Squire-Cogswell/Aeros Instruments, Inc. was
formed in 1916 as a supplier of railway and foundry
equipment in Chicago. In 1951 the company was purchased
by Walter F. Devereux and began to concentrate its efforts
on a line of non-lubricated air compressors and vacuum pumps. A niche was found
servicing the printing press industry with new and rebuilt pumps. Utilizing this expertise,
the company began to supply custom pump packages for various applications. In the
early 1950's, Squire-Cogswell/Aeros Instruments, Inc. sold its first hospital vacuum
pump package, the cornerstone of today's business and product lines.
In 1962 Herbert E. Schifter, Mr. Devereux's son-in-law, became president. The business
then grew significantly as a supplier of custom designed and constructed vacuum and air
compressor systems for medical and industrial use. To date, Squire-Cogswell/Aeros
Instruments, Inc. has manufactured over 15,000 hospital pumping systems that have been
installed literally around the world.
Today, in the third generation of family ownership by Craig Schifter and his sister, Carol
Lewis, the company continues to serve the worldwide needs of hospitals, laboratories,
and industrial companies. Squire-Cogswell/Aeros Instruments, Inc. products are
distributed through the company's direct sales force and through a network of dealers and
distributors.
Aeros Instruments, Inc. (now known as Squire-Cogswell/Aeros Instruments, Inc.) is an
FDA registered, ISO 13485 certified, UL listed medical device manufacturer. Aeros was
formed in 1962 as a wholly owned subsidiary of the Squire-Cogswell Company for the
purpose of supplying suction equipment to the medical industry. Aeros now offers
multiple models of electric and battery operated suction machines for hospitals,
surgicenters, homecare, and EMS applications.
Along with its own branded products, Aeros Instruments also manufactures and sells
other devices for medical suction and medical gas regulation to other marketing
companies on a private labeled, OEM basis. Primary to the Aeros Instruments product
mix is the assembly and distribution of suction regulators and flowmeters for one of the
largest sellers of such devices in the world.
Aeros Instruments and Squire-Cogswell are both regular suppliers to the military and U.
S. government.
In the 1950's and 60's the companies were located in Chicago, Illinois. In 1969 we
constructed a 48,000 square foot building and moved to Northbrook, Illinois. On
December 1, 1993, Squire-Cogswell/Aeros Instruments, Inc. began operations in a brand
new 84,000+ square foot corporate headquarters along Interstate 94 in Gurnee, Illinois,
mid-way between Chicago and Milwaukee.

SELECTION GUIDE
ZERO CITY WATER USAGE Laboratory Air Compressor and Vacuum Pump Systems
LABORATORY AIR COMPRESSOR SYSTEMS
Single-Stage & Two-Stage Oil-Less Piston Air Compressor Systems are used for many applications generally
installed in mechanical rooms at facilities. Most air pressure requirements are for 50 PSIG delivery pressure
to facility’s main air distribution line. For compressed air pressure requirements of 85 to 130 PSIG delivery
pressure, Two-Stage Oil-Less Piston Air Compressors are suggested. Chilled water cooled compressed air
after-coolers are available to reduce room heat load/temperature/possibly size of dryers. Air-Cooled and
COMBINATION AIR-COOLED / CHILLED WATER COOLED AFTER-COOLER Air Compressor Systems
are also available to accommodate particular situations.
Oil-Less Scroll Air Compressor Systems are suggested when low noise level is needed close to occupied areas,
low vibration is needed close to vibration sensitive instruments/occupied areas, and/or when needed for a small
capacity unit at higher delivery pressures up to 130 PSIG. Air-cooled after-coolers are common. Chilled
water cooled after-coolers are available to accommodate special situations.
LABORATORY VACUUM PUMP SYSTEMS
Oil-Sealed Liquid Ring Vacuum Pump Systems are one of the most reliable and low maintenance vacuum
sources available. Systems sealed with 10 WT Food Grade Oil (or equivalent) containing anti-wear agents,
anti-oxidents, and corrosion inhibitors are tolerant to many corrosive vapors/gasses. Chilled water cooled
systems are suggested to reduce room heat load/temperature and to accurately control operating temperature at
optimum level. Air-Cooled and COMBINATION AIR-COOLED / CHIILED WATER COOLED Systems are
also available to accommodate particular needs.
Single-Stage Liquid Ring Vacuum Pumps are used for maintaining design vacuum levels up to 19 to 21”HGV.
Two-Stage Liquid Ring Vacuum Pumps should be considered for design vacuum levels greater than 22”HGV.
Oil-Lubricated/Recirculated Single-Stage Rotary Vane Vacuum Pump Systems are used for general service
when (as a rule) corrosive vapors/gasses and liquids are not present. These are not recommended for low
vacuum applications. CHIILED WATER COOLED ASSIST OPTION is used to prolong pump life, extend
maintenance intervals, and/or compensate for expected high equipment room temperatures/altitudes.
Oil-Less Dry-Running Single-Stage Rotary Vane Vacuum Pump Systems are suggested for mildly corrosive
vapors/gasses, and when low to medium vacuum levels are sufficient to service facility.
NOTES:
1. GENERAL RULE OF THUMB SIZING CRITERIA FOR TYPICAL MEDIUM SIZED LABS:
COMPRESSED AIR --- ¾ SCFM PER OUTLET WITH 50% USAGE FACTOR.
VACUUM --- 1.0 SCFM PER OUTLET WITH 50% USAGE FACTOR.
Consult factory for other lab sizes and applications.
1. Determination of delivered pressure dew point of compressed air is important for optimal dryer selection.
Other vacuum systems are available such as water sealed and recirculated LRVP systems for “wet” service.
2. CAPACITY SPECS - Air Systems in terms of SCFM @ __ PSIG & Vacuum Systems as SCFM @ __ “HGV.
For performance spec consistency and definition, suggest SCFM capacity basis of 14.7 PSIA, 68F, and 36% R.
H. for compressors and 29.92”HGA, 68F, and 50% R.H. for vacuum pumps.
1. Performance levels listed apply to standard barometer conditions. Consult factory for other conditions.
2. Systems meet latest edition of NFPA 99 for Lab Facilities and conform to National Electrical Code.
3. Standard motors are rated for room ambient temperatures up to 104F.
4. Factory (authorized) start-up assistance/in-service training are included in scope of supply.

LIQUID COOLING…IT’S BTU-TIFUL!
The good news is that there are effective ways to deal with the problem. Even though all manufacturers of air cooled
equipment provide adequate cooling for their own equipment, the cumulative effect of multiple units can have a
detrimental effect on the performance and longevity of mechanical, electrical, and electronic components.
The use of a facility’s chilled water system can greatly assist in the reduction of local heat loads and the
extension of component life. For example, on liquid ring vacuum systems the local heat load can be reduced by 25 to
30 BTU’s/minute per HP through the use of chilled water. On oil sealed rotary vane systems the heat reduction can
average 15 to 20 BTU’s /minute per HP. And chilled water aftercoolers on oil-less piston compressors can help remove
15 BTU’s /minute per HP.
In the case of oil sealed rotary vane systems, the use of a small adapter and liquid to liquid heat exchanger represents an
inexpensive addition with substantial benefits. Cooler operation translates into longer service intervals. It is estimated
that, for every 15 to 18 degrees F above the maximum rated operating temperature of an oil in a rotary vane pump on
clean service, the oil degradation rate doubles. To the extent that the pump is operating on less than clean service
(often the case), the maximum operating temperature of the pump’s oil will be reduced.
Reduction of local heat loads also provides advantages to electrical components. Electric Motors Rule of Thumb is that
each 18 degree F rise above the highest allowable stator winding temperature reduces the motor insulation useful life in
half. Motor contactors inside electrical panels can also be adversely affected by excessive heat, especially due to short
cycling of pumps. The use of minimum run timers and properly sized receivers will help prevent this condition.
How much will this heat reduction cost in terms of chilled water? For removing 15 BTU’s/minute from either an air
compressor or vacuum pump system, the additional load is about 0.085 chiller HP for water-cooled chillers (via
cooling towers) and about 0.10 chiller HP for air cooled chillers.
The use of chilled water on the systems described can help reduce the air temperature around the systems by 7 to 20
degrees F, depending on type of system. Temperature reduction is based on access space of 2 to 3 feet around systems
and ceiling height of 12 feet.
Selection Guide / Liquid Cooling
Remember that mechanical room that used to be 75 degrees back when there were only 3 pieces of equipment in the
room? Chances are that, as the facility’s equipment needs have grown, the ambient temperature of the room has grown
right with it. It’s well known that heat is a major enemy of mechanical equipment.

PRINCIPLE OF OPERATION
LIQUID RING VACUUM PUMPS
Figure 1 shows a cross section of a liquid ring vacuum pump. The impeller is cylindrical in shape
with a multitude of fins and is located eccentrically in the impeller housing which is partially filled
with the sealing liquid, either water or oil. A port plate with suction and discharge openings is located
on each side of the impeller cell.
As the impeller rotates, the centrifugal force pushes the sealing liquid outward where it forms a liquid
ring which follows the contour of the impeller housing. Starting at point "A" the impeller cell is completely filled with the sealing liquid.
As the impeller advances, the liquid in the cell recedes and creates a vacuum in the empty space, which
draws in the air or gas through the suction port. Continued rotation increases the gas volume in the impeller cell until the end of the suction cycle at point "B".
From point "B", the liquid is gradually forced back into the impeller cell, compressing the gas to near
atmosphere, until at point "C" the compressed gas is expelled through the discharge port together with
a portion of the sealing liquid.
The complete cycle can be compared with a piston in a cylinder where the piston is the liquid ring and
the impeller cell is the cylinder. The heat generated by the pump during the compression cycle is dissipated into the sealing liquid.
The discharged sealing liquid is recirculated back from the separator tank to the pump on Partial Recirculating Systems. Any fresh make-up seal liquid is controlled by the liquid temperature and level
switches, reducing consumption of fresh water.
Total Recirculating Systems are available in either water sealed or oil sealed configurations, utilizing a
heat exchanger, and eliminating the requirement for fresh make-up seal liquid. The heat exchanger removes the heat from the seal liquid before it is re-introduced into the pump.

ROTARY VANE VACUUM PUMPS
Discharge
The SelecTORR® vacuum pump operates as follows:
The rotor is mounted on the drive shaft and positioned eccentrically in the cylindrical casing. The
rotor has slots for radially sliding vanes, which divide the pump chamber into segments. The centrifugal force of rotation pushes the vanes out of these
slots and toward the wall of the casing. As the rotor
turns, the gas is drawn through the inlet, compressed
and pushed out through the exhaust.
Inlet
Vanes
In lubricated vacuum pumps, the lubricating oil collects in the bottom of the exhaust oil separator chamber as the gas passes through a demister, then
through an exhaust filter, before finally exhausting to
the atmosphere.

OIL-LESS RECIPROCATING PISTON AIR COMPRESSORS
With the down stroke of the piston, air is
drawn through an intake valve in the head of
the compressor and into the cylinder. At the
bottom of the stroke the intake valve closes
and air is trapped in the cylinder. The air is
then compressed in the cylinder and pushed
through the discharge valve on the up stroke
of the piston. Total compression, from atmospheric pressure to the final discharge
pressure, is accomplished in one stroke of
the piston.

Refrigerated Air Dryers
Principal of Operation
Compressed air enters the air-to refrigerant heat exchanger (A) where it is cooled
by the refrigeration system to the desired
dew point temperature. As the air is
cooled in the heat exchanger, water vapor
condenses into liquid droplets.
The air and entrained water droplets then
enter the separator (B) where liquid water
droplets are removed from the air stream.
An automatic drain (C) discharges the collected water from the system. As long as
the temperature of the compressed air
does not fall below the dew point temperature produced in the dryer, the remaining
water vapor will not condense into troublesome liquid in downstream air lines. This
dryer fully meets the NFPA 99 requirements for 32°F.
Desiccant Air Dryers
Principal of Operation
A single desiccant dryer consists of two towers, primary and secondary and a instrument panel. This dryer fully meets the
NFPA 99 requirement for 32°F.
Compressed air enters the bottom of the desiccant dryer where the switching valve directs the compressed air to the
primary tower. The up flow drying allows water and heavy contaminates to drop out of the air stream as they enter the
tower protecting the desiccant bed from contamination. The air is dried in the tower and directed through a series of check
valves and discharged through the outlet.
A portion of the dried air is diverted through an
adjustable purge valve where it is throttled to
near atmospheric pressure and the secondary
Purge
tower.

This dried low-pressure air is called purge air,
which regenerates the desiccant in the
secondary tower by carrying off the water
collected. The purge air is then exhausted to
atmosphere through the purge valve and
muffler.
After regeneration, the purge valve closes and
the secondary tower depressurized to line
pressure.
An inlet switching valve on the secondary
tower then opens and the inlet switch valve on
the primary tower closes and the purge valve
on the primary tower is opened. The inlet air is
now being dried in the secondary tower while
the primary tower is being regenerated.
