SECTION 1
EQUIPMENT CHECK
Before uncrating, check the packing slip carefully to be sure all the parts have been received. All
accessories are listed as separate items on the packing slip, and small important accessories such as
relief valves can be overlooked or lost. After every item on the packing slip has been checked off,
uncrate carefully. Register a claim with the carrier for lost or damaged equipment.
Customers are cautioned to provide adequate protection, warning and safety equipment
necessary to protect personnel against hazards involved in installation and operation of this
equipment in the system or facility.
STORAGE
Your Gardner Denver Blower was packaged at the factory with adequate protection to permit normal
storage for up to six (6) months.
If the unit is to be stored under adverse conditions or for extended periods of time, the following additional
measures should be taken to prevent damage.
1.
Store the blower in a clean, dry, heated (if possible) area.
2.
Make certain inlet and discharge air ports are tightly covered to prevent foreign material from
entering the air box.
3.
All exposed, non-painted surfaces should be protected against rust and corrosion.
4.
Provide adequate protection to avoid accidental mechanical damage.
5.
In high humidity or corrosive environments, additional measures may be required to prevent
rusting of the blower internal surfaces.
6.
To prevent rusting of gears, bearings, etc., the oil reservoirs may be filled with normal
operating oil.
Before running the blower, drain the oil and replace to the proper operating level with clean,
fresh lubricant.
7.
Rotate the blower shaft (10 to 25 turns) monthly during storage. Inspect the blower shaft
(near the shaft seal area) monthly and spray with rust inhibitor if needed.
8.
For long term storage (over six (6) months), contact Gardner Denver Compressor Division
Customer Service for recommendations.
TF-7-600
Page 9
REMOVING PROTECTIVE MATERIALS
The shaft extension is protected with rust inhibitor which can be removed with any standard solvent.
Follow the safety directions of the solvent manufacturer.
Blower inlet and outlet are temporarily capped to keep out dirt and other contaminants during shipment.
These covers must be removed before start-up.
The internal surfaces of all TriFlow blowers are mist sprayed with a rust preventative to protect the
machine during shipment. Remove this film upon initial startup, using any commercial safety solvent.
Position the blower so that the inlet and discharge connections are in the vertical position (vertical
airflow). On vertically mounted units, it will be necessary to lay the unit on its side supporting the ends of
the unit so as not to restrict the portion on the bottom side. Place a shallow pan on the under side of the
unit. With the blower disconnected from power, spray the solvent in the top port, rotating the impellers by
spinning the shaft manually. Continue this procedure until the unit is visibly clean.
Rotating components will cause severe injury in case of personal contact. Keep hands away
from blower inlet and discharge ports.
TF-7-600

SECTION 2
INSTALLATION
LOCATION
If possible, install the blower in a well lit, clean, dry place with plenty of room for inspection and
maintenance.
FOUNDATIONS
For permanent installations we recommend concrete foundations be provided, and the equipment should
be grouted to the concrete. It is necessary that a suitable base be used, such as a steel combination
base under blower and motor, or a separate sole plate under each. Before grouting equipment must be
leveled, free of all strains, and anchored so no movement will occur during setting of grout. After grout
has completely hardened, a recheck is necessary to compensate for shrinkage, etc. If required, add
shims under blower feet after final tightening of foundation anchor bolts to remove strain from the blower
housing. Where jack screws or wedges are used during grouting, they must be backed off or removed
before final tightening of anchor bolts.
Where a concrete foundation is not feasible, care must be taken to insure that equipment is firmly
anchored to adequate structural members.
MOUNTING CONFIGURATIONS
The blower flex-mounting design enables horizontal and vertical mounting configurations with top or
bottom hand, right or left hand shaft positioning. The units are discharge timed allowing rotation in only
one direction (refer to FIGURE 2-1). If converting a blower from vertical bottom hand drive to vertical top
hand drive or vice versa, the oil slinger on each end must be moved to the lower rotor.
FIGURE 2-1 – BLOWER MOUNTING CONFIGURATIONS
TF-7-600
Page 11
NOTICE
When changing mounting configuration, it will be necessary to reposition oil level gauge (H),
and drain plug (A). Refer to FIGURE 3-1, for correct location.
For Vertical Models, the oil slinger must be on the lower rotor or blower failure is immediate.
DRIVE INSTALLATION
When selecting a V-belt drive, check to be sure the shaft overhung load limitation is not exceeded. Refer
to FIGURE 2-2 for overhung load calculations and limitations.
Belt drives must be carefully aligned. Motor and blower sheaves must be parallel to each other and in the
same plane within 1/32 inch. Belt tension should be carefully adjusted to the belt manufacturer’s
recommendation using a belt tension gauge. Check tension frequently during the first day of operation.
Overtightening belts leads to heavy bearing loads and premature failure.
On the direct connected units, alignment and lubrication of couplings to specifications of the coupling
manufacturer is very important. When mounted drives are supplied from the factory, proper alignment
has been established before shipment. However, during shipping, handling, and installation, it is likely
that the alignment has been disturbed and final adjustment must be made before startup.
Exceeding overhung load limitations leads to unwarrantable premature bearing failure and shaft
breakage.
The location of the sheave on the blower shaft greatly affects the stress in the shaft. The optimum blower
sheave positioning is as close as possible to the blower drive cover, not to exceed dimension “C” in Drive
Shaft Illustration, FIGURE 2-2.
The calculated shaft moment must not exceed the maximum allowable moment listed in Maximum
Allowable Moment Chart, FIGURE 2-2. If the calculated shaft moment exceeds the maximum allowable
moment:
•
Increase Sheave Diameters to Reduce Belt Pull
•
Use Jackshaft Drive
•
Use Direct Coupled or Gearbox Drive
To calculate shaft moment for a given V-Belt Drive Arrangement:
1.
Use the formula for Calculation of Belt Pull, FIGURE 2-2, to calculate belt pull. Refer to Arc
of Contact Factor Chart, FIGURE 2-2.
2.
Insert the calculated belt pull into the formula for Calculation of Shaft Moment, FIGURE 2-2,
to arrive at the calculated shaft moment.

PIPING
Inlet and discharge connections on all blowers are large enough to handle maximum volume with
minimum friction loss. Reducing the pipe diameter on either inlet or discharge will only create additional
line loss and increase the overall pressure differential.
Excessive weight of piping and fittings will cause internal misalignment and premature wear. Never allow
the blower to carry the weight of the pipe. If possible, a spool or sleeve-type expansion joint should be
installed between the unit and the piping. Where a flexible connection is not practical, the weight of the
rigid connection must be separately supported. All system piping must be cleaned internally before
connecting to the blower.
Gardner Denver blowers are shipped dry from the factory. Do not attempt to operate the blower
before following proper lubrication instructions. Permanent damage to the gears, bearings and
seals will occur.

Add fresh oil as required to maintain proper level. If premium grade mineral oil is used, the oil should be
drained, the gearbox flushed and the oil replaced every 1500 hours or more frequently if inspection so
indicates. The oil drain plug is located at (A). With AEON PD synthetic blower lubricant, perform the
above oil-change maintenance after 4500 to 7500 hours.
Do not overfill as this will tend to cause excessive heating of the gears and may damage the
unit.

For continuous operation, where the lubricant temperature exceeds 200° F, synthetic lubricant
is recommended.
AIR FILTERS AND FILTER SILENCERS
Servicing the air filters is one of the most important maintenance operations to be performed to
insure long blower life.
Servicing frequency of filter elements is not time predictable. A differential pressure indicator, with a
continuous gauge reading, should be installed across the inlet filter. It will tell how much of the service life
of the filter element has been used. It will also eliminate both premature filter servicing and premature
blower failure due to a plugged filter when the filter pressure drop is used to establish maintenance
points.
In all cases refer to the filter manufacturer’s service instructions. Due to the many types of filters, it is not
practical to give specific instructions covering all models.
NOTICE
No matter what type of filter is used, always make sure all seats, gaskets, clamps and hose
connections on the filter and inlet line are absolutely air tight. Each time the filter is serviced,
inspect interior of the blower for dirt.
TF-7-600

SECTION 4
OPERATION
Future operating problems can be avoided if proper precautions are observed when the equipment is first
put into service.
Before starting under power, the blower should be turned over by hand to make certain there is no
binding, or internal contact. DO NOT OPERATE THE BLOWER UNLESS OIL LEVEL IS AT MIDDLE OF
EACH SIGHT GLASS. DO NOT OVER FILL.
Each size blower has limits on pressure differential, running speed and discharge temperature and
temperature rise which must not be exceeded. These limits are shown FIGURE 4-1.
Operating beyond the specified operating limitations will result in damage to the unit.
It is important that the pressures and temperatures are measured directly at the ports of the blower to
avoid error that may be caused by intervening pipe runs, fittings, etc.
Relief valves should be used to protect against excessive pressure or vacuum conditions. These valves
should be tested at initial startup to be sure they are adjusted to relieve at or below the maximum
pressure differential rating of the blower.
NOTICE
Relief valves should be placed as close as possible to the blower inlet or discharge.
In some instances, pressure may be relieved at a lower point than the blower maximum in order to protect
the motor or the equipment served by the blower.
Discharge temperature switches are recommended to protect against excessive inlet restriction or inlet
temperatures. Check valves in the discharge line on pressure blowers and in the inlet line on vacuum
blowers are recommended to protect the blower from motoring backwards when shut down under load.

BLOWER STARTUP CHECKLIST
This startup procedure should be followed during the initial installation and after any shutdown periods or
after the blower has been worked on or moved to new location. It is suggested that the steps be followed
in sequence and checked off (√) in the boxes provided.
1.
Check the unit and all piping for foreign material and clean if required.
2.
Check the flatness of the feet and the alignment of the drive. Feet that are bolted down
in a bind can cause housing distortion and internal rubbing. Misaligned V-drives can
cause the rotors to rub against the headplates and cause a reduction in the volumetric
efficiency of the unit. Misaligned couplings can ruin bearings.
3.
If the blower is V-belt driven, check the belt tension and alignment. Over-tensioned belts
create heavy bearing/shat loads which lead to premature failure.
4.
Be sure adequate drive guards are in place to protect the operator from severe personal
injury from incidental contact.
5.
Check the unit for proper lubrication. Proper oil level cannot be over-emphasized. Too
little oil will ruin bearings and gears. Too much oil will cause overheating and can ruin
gears and cause other damage.
6.
With motor electrical power locked out and disconnected, turn the drive shaft by hand to
be certain the impellers do not bind.
7.
“Jog” the unit with the motor a few times to check that rotation is in the proper direction,
and to be certain it turns freely and smoothly.
8.
The internal surfaces of all Gardner Denver units are mist sprayed with a rust preventive
to protect the machine during the shipping and installation period. This film should be
removed upon initial startup.
9.
Start the unit and operate 15 minutes at no load. During this time, check for hot spots
and other indications of interference.
10.
Apply the load and observe the operation of the unit for one hour. Check frequently
during the first day of operation.
11.
If malfunctions occur, do not continue to operate. Problems such as knocking rotors can
cause serious damage if the unit is operated without correction.
TF-7-600

DISASSEMBLY INSTRUCTIONS
1. Inspect the interior of the blower for any signs of rotor contact (rotor to rotor, tip to case, rotor end to
bearing housing). If there are signs of contact then the various clearances should be measured with
feeler gauges prior to any disassembly.
2. Inspect the areas around the drive shaft seal and vent passages in the bearing housing and air
cylinder for any signs of oil leaks.
3. Drain the oil from the gear end and drive end sumps by removing their drain plugs (2). A small
amount of oil from each sump should be saved in the event that an oil analysis will be required.
4. Remove the screws (5) from the drive end sump cover (29). Remove the sump cover by sliding it off
the drive shaft.
5. Inspect the drive shaft in the area of the oil seal for damage and wear. Inspect the oil seal (31).
6. Support the external surface of the drive end sump cover near the oil seal with blocks of wood. Drive
the oil seal from the cover.
7. Remove the screws (5) from the gear end sump cover (3). Remove the sump cover.
8. Remove the bolt (8), washer (6), and oil slinger (26) on the gear end from the rotor shaft.
9. If it appears the gears can be reused their backlash should be measured. Lock the idler rotor from
turning by wedging a shop rag between the tip of a lobe and the air cylinder. Measure the backlash of
the gears using a dial indicator and magnetic base. The backlash should be measured in 3 places
(every 1/3 turn). Permissible gear backlash is shown in Figure 7-18.
10. If timing gears are reusable match mark the gears by making small punch marks on the ends of 2
meshing teeth.
11. The taper pin should back out with gear as the gear is being removed. Use caution not to damage
gear teeth with puller if gears are to be used again.
12. Remove the gears (9) from both rotor shafts, using a gear puller.
13. On gear end, remove the 4 bearing retaining screws (10) and washers (12) from the air cylinder.
14. Position the blower assembly vertically with the drive end up. Support the gear end of the air cylinder
on blocks to protect the ends of the rotor shafts.
15. Remove the locknuts (36) from both of the rotor shafts on the drive end using nut driver tool
(EQ143816).
16. Remove the oil slinger (27) from its rotor shaft.
17. Remove the spacer (49) from each rotor shaft.
18. Remove the 6 socket head screws (21) and washers (20) that attach the bearing housing (24) to the
air cylinder (22).
TF-7-600
Page 28
19. Remove the bearing housing from the air cylinder using two 2 jaw pullers. The jaws of the puller must
be narrow enough to fit in the rectangular holes in the bearing bosses. A shaft protector (soft spacer)
must be placed over the end of each rotor shaft. Both pullers must be tightened evenly during this
process. There are 2 dowel pins that locate the bearing housing relative to the air cylinder. If the
bearing housing is tilted during removal these dowel pins may break out of their holes.
20. Remove the 2 seal flingers (34) from their bores in the bearing housing.
21. Remove the ball (14) and roller bearing (35) from their bores in the bearing housing using a ball peen
hammer and punch. Exercise care not to damage the bearing bores.
22. Position the blower assembly horizontally.
23. Match mark the rotors by making small punch marks on the ends of the meshing lobes.
24. Push the drive rotor (23B) shaft through the air cylinder using a 2 jaw puller. The puller jaws must be
narrow enough to fit in the rectangular holes in the bearing boss. A shaft protector (soft spacer) must
be placed over the end of the rotor shaft. Remove the driver rotor from the air cylinder.
25. Push the idler rotor (23A) shaft through the air cylinder using a 2 jaw puller. Remove the idler rotor
from the air cylinder.
26. Remove the 2 seal flingers (34) from their bores in the air cylinder.
27. Remove the 2 ball bearings (14) from their bores in the air cylinder using a ball peen hammer and
punch. Exercise care not to damage the bearing bores.
28. Inspect the 3 piston rings (15) on both ends of both rotors for signs of damage and abnormal wear.
Remove the piston rings from each of the 4 ring carriers (33).
29. Inspect the ring carriers for signs of damage and abnormal wear. Normally it is not required to replace
the ring carriers.
30. If a ring carrier is damaged it may be removed by heating with a torch. The rotor should be placed in a
vertical position and continuously rotated while the ring carrier is being heated. Caution should be
used when performing this procedure as the rotor can be damaged by uneven and extreme heating.
31. Inspect the inserts (32) in the 4 bearing bosses (2 in bearing housing and 2 in air cylinder) for signs of
damage and abnormal wear. Normally it is not required to replace the inserts.
32. If an insert is damaged it may be removed by using a hydraulic press and suitable driver tool. It must
be removed from the air side of the bearing housing or air cylinder.
TF-7-600

SECTION 7
ASSEMBLY INSTRUCTIONS
1. Make sure all metallic parts are clean and free of any nicks or burrs prior to assembly.
2. Apply Loctite 620 to the outside diameter of the bearing carrier inserts (32). The large diameter side
of the inserts are to be flush with the air or pressure side of the bearing housing. Be sure to orient the
air vent holes in the inserts at 0, 90, 180, and 270 degrees before pressing them into the housing.
Support the housing under the bearing bosses. Use a hydraulic press and insert driver tool
(EQ143639) to install the inserts (32) into the bearing housing (24) from the air side.

4. Apply Swagelok thread sealant to vent plugs (47) and thread them into the cylinder housing.
Figure 7-6
Figure 7-7
5. Apply Loctite 620 to each end of the drive rotor shaft (23B) and each end of the idler rotor shaft (23A).
Heat the ring carriers (33) to 275°F and press up against the face of the rotor body on each end of
both the drive rotor and the idler rotor using a hydraulic press and driver (EQ143806) tool.
Figure 7-8
Figure 7-9
Figure 7-10
Figure 7-11
After heating use a gauss meter to check the ring carriers for magnetism. The magnetic flux density
must be less than one gauss. The carriers must be orientated so that their stepped face does not
contact the rotor body. After the ring carriers have cooled ensure that they are still tight against the
face of the rotor.
TF-7-600
Page 31
6. Install the ring seals (15) to the gear end of both rotors. Lock the ring ends together after installation.
Alternate the location of adjacent ring connections by 180 degrees.
Figure 7-12
7. Lightly oil the ring seals and the bearing carrier bores of the cylinder housing. Gently slide both rotors
into the cylinder housing using assembly guide tool (EQ143805) shown on page 24. Rotate the
assembly so that both rotors are supported vertically and the cylinder housing is resting flat against
the ends of the rotor lobes.
Figure 7-13
Figure 7-14
8. Heat the slingers (34) to 375°F and press onto the gear end of both shafts using a hydraulic press
and insertion tool (EQ143806) shown on page 23. No loctite is required. Each rotor must be
supported firmly from the opposite end when pressing on the slinger.

9. Place false bearing (149908) (shown on page 24) into each bearing pocket and take measurements
with a depth micrometer to calculate the proper amount of shims to be used to meet the end
clearances shown in table FIGURE 7-18. Remove false bearing after measurements are taken.
Figure 7-17
How to calculate the proper thickness of shim stock to use:
Measure the step between the inner and outer ring of the false bearing.
If the inner bearing ring is higher than the outer ring, then subtract this amount from the end
clearance requirement shown in Figure 7-18, and the difference between these two numbers will
be the amount of shims required.
If the outer bearing ring is higher than the inner ring, then add this number to the end clearance
requirement shown in table Figure 7-18, and the sum of these two numbers will be the amount of
shims required.

If there is no step between the inner and outer bearing rings, then the amount of shims required will
be exactly equal to the end clearance requirement shown in table Figure 7-18.
NOTICE
Both rotors must be held firmly against the gear end of the cylinder housing when
measurements are taken. Rotors that are not seated against the cylinder will result in
improper end clearances and may cause poor performance or damage to the blower.
Figure 7-19
10. Add shims (13) to each shaft and press the gear end bearings (14) into position using a hydraulic
press and insertion tool (EQ103807-1) shown on page 25. Add a few drops of oil to the bearings
after assembly.
Figure 7-20
Figure 7-21
Figure 7-22
Note: Because the bearing is slightly thicker than the bearing bore depth, the outer race should
remain slightly higher than the bearing pocket when fully seated.
TF-7-600
Page 34
11. Assemble the bearing retainer bolts (10) and washers (12) to the bearing housing. Torque bolts to
38-41 ft-lbs.
Figure 7-23
12. Place a paper chip cover or shield over the unit leaving only the rotor ends exposed, to prevent metal
chips from contaminating the bearings. Apply a small amount of grease to the O.D. near the end of
each rotor shaft. Clean and install the gears (9) onto the rotor shafts. Be sure to orient the timing
marks of each gear 180° apart to minimize gear backlash. Press both gears onto the rotor shafts at
the same time using a hydraulic press and gear driver tool (EQ144034). The gears should be
pressed down until flush with the ends of the rotor shafts. No loctite is required. Gears will be pinned
to the shafts after the interlobe clearance is set.
Figure 7-24
13. Rotate the blower to the horizontal position and install ring seals (15) to the drive end ring carrier of
both rotors. Lock the ring ends together after installation. Alternate the location of the adjacent ring
connections by 180°.
Figure 7-25
TF-7-600
Page 35
14. Rotate the blower so that the drive end is up. Be sure to support the blower by the gear end rotor
shafts and not by the cylinder housing. Measure the distance from the top end of the rotor lobes to
the machined face of the cylinder housing using a depth micrometer. If this distance does not match
the required drive end clearance requirement from table Figure 7-18, then paper shims must be
added to achieve the proper end clearance. Add paper shims if required. Supporting the cylinder
housing tap the locating dowel pins (19) into the top side of the cylinder housing. Lower the bearing
housing over the top of the rotor shafts and onto the cylinder. Install six bolts (21) and washers (20)
into the bearing housing and torque to 38-41 ft-lbs.
Figure 7-26
Figure 7-27
15. Be sure to support the blower by the gear end rotor shafts and not by the cylinder housing. Heat
slinger (34) to 375°F and press onto the drive end of both shafts. No Loctite is required. Same
procedure as shown in step #8.

16. Press the drive end bearings (14 and 35) into position using a hydraulic press and insertion tool
(EQ143807-1)shown on page 25 Install roller bearing (35) with the inner race flange on the outside.
See Figure 7-29 & 7-30. Place a tie wrap or O-ring on the OD of the bearing to keep the rollers
engaged with inner race during installation. Be sure that the blower is being supported from the
bottom side by the two rotors and not by the cylinder housing. Add a few drops of oil to the bearing
after assembly.

18. Add spacer rings (49) to each rotor and install the oil flinger (27). The oil flinger will be installed on
the idler rotor if the unit is a horizontal configuration and it will be installed on the bottom (lowest) rotor
if the unit is a vertical configuration. Apply Loctite 262 to the threads of each rotor shaft and
assemble a bearing lock nut (36) to each rotor. Torque the lock nuts to 45-50 ft-lbs using the socket
tool (EQ143816) shown on page 26.
Figure 7-31
TF-7-600
Page 37
18. Rotate the blower to a horizontal position and check the interlobe clearances. Check the interlobe
clearances by inserting a feeler gauge between the rotor lobes as they are rotated to their closest
position. Both the “closed” and “open” clearance must be checked. The “open” clearance is the
minimum gap between the leading edge of any drive rotor lobe and the trailing edge of the nearest
idler rotor lobe. The “closed” clearance is the minimum gap between the trailing edge of any drive
rotor lobe and the leading edge of the nearest idler rotor lobe. Minimum interlobe clearance values
are shown in Figure 7-18. If the actual measured total clearance is larger than the sum of the open
minimum and the closed minimum specified in Figure 7-18, then the total clearance should be divided
such that 1/3 of it is on the closed side and 2/3 of it is on the open side. Neither of the actual
clearances can be less than the minimum specified clearances.
Figure 7-32
If the interlobe clearance does not meet the minimum values shown in the table, then the clearances
must be adjusted. To adjust the clearances, place a thin piece of shim between the two lobes you
wish to adjust and rotate the drive rotor until contact is made. This is called “bumping” the timing and
can be used to manually set the interlobe clearances.
19. Check the rotor end clearances by inserting a feeler gauge into the gap at the end of each rotor. The
minimum end clearances are listed in Figure 7-18.
20. Rotate the blower to a vertical position with the gears up. Drill a 7/32” diameter hole into the top side
of each gear. Center the holes midway between gear and the shaft so that half of the hole is cut into
the gear and half of the hole is cut into the shaft. Drill down to approximately 1/8th inch from the
bottom of the gear. Do not drill completely through the gear. Ream the holes using a #4 taper
reamer. Apply a very thin coat Loctite 620 to each taper pin (18) and drive them into the holes,
locking the gears into place.
Figure 7-33
TF-7-600
Page 38
21. Check the gear backlash by using a magnetic base and a dial indicator. Lock one gear in place by
wedging a shim between the rotor tip and the cylinder wall. Then measure the total movement of the
opposite gear. Gear backlash should be within the allowable range shown in Figure 7-18.
22. Assemble gear end flinger (26) to the shaft using flinger bolt (8) and washer (6). Apply Loctite 262 to
the flinger bolt before assembly. The oil flinger will be installed on the idler rotor if the unit is a
horizontal configuration and it will be installed on the bottom (lowest) rotor if the unit is a vertical
configuration. Torque the flinger bolt to 29-32 ft-lbs.
