YORK® GENERAL PURPOSE CENTRIFUGAL FAN, MODEL US
FEATURES & BENEFITS
Self Aligning Pillow Block Bearings
Bearings are sized for a minimum L50 life exceeding 200,000
hours of operation. They require no maintenance other than
periodic lubrication. Standard Zerk lube fittings allow for ease
of lubrication. Extended lube lines are available as an option to
facilitate lubrication when a weather cover is used.
Solid Steel Shafts
Sized to withstand a minimum of 125% of maximum catalogued
operating speed, shafts are precision ground, polished, and
treated for rust resistance.
Durable Housings
US blowers are manufactured of heavy gauge zinc coated
galvanized steel to insure a long, corrosion resistant life.
Galvanized steel resists rust and will help maintain the unit’s
integrity even in environments such as coastal regions where
salt air will rapidly deteriorate black iron, even when it is painted.
Typical Drive, Shaft, and Bearings Assembly
Versatile Operation
Spark Resistant Aluminum Wheels
All unit sizes are field rotatable to any of eight discharge positions.
Both clockwise and counter-clockwise rotations are available.
Motors and Drives
The motors and belt drives are pre-set at the factory to the
specified RPM. These drives allow for system balancing in the
field. All pulleys are sized for at least 150% of driven horsepower.
High quality, open drip proof motors are standard. Totally
enclosed, explosion proof, and two speed motors are available.
Heavy Duty Support Frame
The heavy duty support frame provides a strong structural
foundation for the motor and drive assembly, as well as rigid
reinforcement for housing members.
Standard Gasketed Access Door
The standard gasketed access door enables easy maintenance
of internal components.
Inlet Angle Flange
The inlet angle flange is standard to facilitate connection to the
duct work.

US blowers use our computer designed, aluminum wheel. They
are backward inclined and non-overloading, using heavy gauge
aluminum to provide AMCA “C” spark resistant construction.
AMCA “B” construction is available as a moderate cost option.
This wheel design provides a high level of static efficiency while
reducing start-up torque, thus extending drive component life.
All wheels are statically and dynamically balanced for quieter
operation.
Steel Wheel (Heat & Smoke Removal)
The wheel is a standard duty, all welded wheel (standard duty
and high pressure belt drive). The blades are curved for improved
air performance while increasing their strength and rigidity. The
wheel assembly is fully welded to provide extremely durable and
consistent performance. The wheel is dynamically balanced.
Balancing weights are mechanically attached to the inside of the
rims of both the back plate and wheel inlet. This allows a precise
placement of the weights anywhere within a full 360° range on
two separate planes, without the possibility of detachment.
Integral Lifting Lugs
All units come standard with integral lifting lugs. These are built
into the back support structure of the scroll housing and can be
used with or without the weather cover installed.
YORK® GENERAL PURPOSE CENTRIFUGAL FAN, MODEL US
OPTIONS & ACCESSORIES
Finishes
Extended Lube Lines
Coatings, such as Polyester Powder Coat, Epoxy Powder Coat,
Phenolic Epoxy Powder Coat, and others are available. See the
coatings brochure for details.
Preloaded at the factory, lube lines allow bearing maintenance
when a weather cover is installed or when easy access to the
bearings is unavailable.
Drain Connections
Spark-Resistant Construction
Drains are made of 2” pipe which is mechanically fastened and
sealed to prevent leakage at the lowest point of the scroll. All fans
can be supplied with drains except bottom horizontal discharge,
where it is not required.
AMCA “C” and “B” construction are available. AMCA standards
offer the following definitions and notes concerning sparkresistant construction:
Dampers
Dampers can be installed at the discharge outlet to prevent
backdrafts when fans are not in operation. Dampers can be used
when outlet velocities do not exceed 4000 FPM for all discharge
positions. Gravity dampers are not effective for use in topangular-down, bottom-angular-down or down blast discharge
positions.
Variable Inlet Vanes
Also known as vortex dampers, vanes provide efficient regulation
of fan output over all operating ranges with substantial increases
in energy efficiency when full fan output is unnecessary. This
accessory is suitable for inlet temperatures up to 200ºF. (Not
available for US10.)
Vibration Isolators, Hangers, and Rails
These items are available in both rubber-in-shear and springtype to mitigate residual vibration transmission. All isolators are
properly sized to the unit. Floor flex pads are also available.
Safety Switches
Switches in housings are available to turn fans on and off for
service only. Field wiring is required.
C. The fan shall be so constructed that a shift in the impeller or shaft will not permit two ferrous parts of the fan to rub or strike.
B. The fan shall have a non-ferrous impeller and non-ferrous
ring about the opening through which the shaft passes.
Ferrous hubs, shafts and hardware are allowed provided
construction is such that a shift in impeller or shaft will not
permit two ferrous parts of the fan to rub or strike. Steps must
also be taken to insure that the impeller, bearings and shaft
are adequately attached and/or restrained to prevent a lateral
or axial shift in these components.
Notes:
1. No bearings, drive components or electrical components shall be placed in the
air or gas stream unless they are constructed or enclosed in such a manner that
failure of that component cannot ignite the surrounding gas stream.
2. The user shall electrically ground on all fan parts.
3. For this standard, non-ferrous material shall be material with less than 5% iron
or any other material with demonstrated ability to be spark-resistant.
4. The use of aluminum or aluminum alloys in the presence of steel which has been
allowed to rust required special consideration. Research by the U.S. Bureau of
Mines and others has shown that aluminum impellers rubbing on rusty steel may
cause high-intensity sparking.
The use of the above standard in no way implies a guarantee
of safety for any level of spark resistance. Spark-resistant
construction does not protect against ignition of explosive gases
caused by catastrophic failure or from any airstream material that
may be present in a system.
Arrangement 10 Single Width, Single Inlet
Fans are constructed with the motor and bearings out of the
airstream. Motors are mounted inside of the pedestal on an
adjustable motor plate. This arrangement allows for the use
of a weather cover and can be used in ducted or non-ducted
applications.
These fans are one component of a system. As such, fan performance is directly
effected by that system. It is critical that system designers determine the actual
system losses to ensure that the actual flow is as specified in the system design.

YORK® GENERAL PURPOSE CENTRIFUGAL FAN, MODEL US
OPTIONS & ACCESSORIES
An extensive selection of accessory items to cover various
application requirements is available at additional cost.
Inlet and Outlet Guards
Inlet and Outlet Guards provide safety in non-ducted installations.
Guards are constructed of expanded steel in a removable
frame attached to the fan housing. They are easily removed by
maintenance personnel for cleaning or inspection.
Ventilated Weather Cover
The weather cover protects the shaft, bearings, motor and drive
components from weather and other detrimental conditions.
Galvanized steel covers are easily removed and reinstalled
with thumb screws, requiring no tools. On larger sizes, the
cover incorporates a removable end panel for easy access to
drive components without removing the entire cover. Weather
covers also act as drive guards to protect personnel and drive
assemblies.
Flanges
Outlet flanges facilitate the connection of duct work. Companion
flanges are also available when the unit is connected to duct
work by a transition section. The companion flange fits the fan to
the transition and guarantees proper sizing.
Access Door
While a gasketed access door is standard, an optional quick
release type door is available to allow for periodic inspection and
cleaning.
Support Angles
Heavy gauge angles, appropriately sized by unit, mean easy
assembly mounting to support surface.

US HEAT & SMOKE CONFIGURATION
UL Power Ventilator for Smoke Control
The Heat and Smoke (-HS) option provides a superior option for smoke control. The UL smoke control listing references UL705,
UL793, Industrial Risk Insurers (IRI), and Southern Building Code Congress International (SBCI). The UL standard requires the
fan to run at 500°F for 4 hours (IRI) and 1000°F for 15 minutes (SBCCI). YORK® by Johnson Controls Heat and Smoke Removal
configured units are listed at 500°F for 4 hours and 1000°F for 41 minutes. The additional 26 minutes at 1000°F will buy precious
time in the event of a fire. The –HS option is available for all sizes offered.
FATRAP CONFIGURATION
Our fans can be specially configured for food service applications with the addition of a group of accessories that either meets a
requirement or eases installation requirements according to NFPA 96. NFPA 96 “Standard for Ventilation Control and Fire Protection of
Commercial Cooking Operations” is the generally recognized authority nationwide for restaurant installation requirements. However,
local codes may vary.
This special configuration is called a “Fatrap.” Fatrap configured fans are ideal for use in commercial kitchens over grills, charcoal
broilers, deep fat fryers, steam tables, ranges, dishwashers, and other appliances.
UL 762 Listing
Grease Collector / Separator Box
Fatrap configured units are listed at 500°F, which is 200°F higher
than UL requirements and is the highest in the industry.
Designed for easy installation, the grease is routed from a single
swiveling collection spout to an amply sized durable galvanized
steel box, trapping grease and residue, and avoiding discharge
onto the roof surface. Additionally, these boxes separate the
water from the grease, prolonging the time required between
periodic maintenance.
US Unipak fans consist of a standard up blast US unit attached
to a fully welded inlet plenum and mounted on a curb cap. The
resulting curb mounted assembly provides a unique solution to
restaurant grease exhaust applications and is UL762 listed. The
Inlet plenum is equipped with a triple sealed removable access
panel which allows cleaning of the fan and duct work without
removal or hinging. This eliminates potential roof or fan damage
caused by cleaning crews. All unwelded mating surfaces (to allow
for service) are sealed with high temperature, UV rated silicone.
The high velocity discharge of the exhaust air stream helps to
disperse contaminants away from the restaurant and minimize
the cloud that sometimes forms as a result of high volume, intense
cooking. The high static pressure capability of these heavy duty
blowers (sometimes greater than 5” w.g.) makes them ideal for
long, complicated duct runs or for use with specialized filtration
equipment. An easily removable weather cover allows access to
motors, belts, bearings, etc., for inspection or maintenance.
Unipak units are available in sizes US10DPFT, US13DPFT,
US16DPFT, US20DPFT and US24DPFT. For performance data,
refer to the corresponding units shown on pages 14 through 22.
Ventilated Curbs
NFPA 96 requires the use of ventilated mounting curbs to provide
an approved arrangement for connecting a range hood and
duct work to the roof fan for buildings two stories or higher. Our
ventilated mounting curbs, 18” high, comply with that standard
when properly installed. Ventilated curbs have a flat mounting
flange for fastening directly to the roof deck. This flange should
be securely fastened and flashed to ensure weather-tightness.
Ventilated pedestals are designed to fit on an existing curb. They
provide cap flashing when so installed.
Pre-Wired Junction Box
A weather-proof junction box is factory wired and mounted to
the housing exterior. An appropriately sized disconnect switch
is commonly selected as an additional option. These items meet
the code requirements for positive electric shut-off.

Rotation & Discharge
Dimensions
The direction of rotation is determined
from the drive side of the fan. On
single inlet fans, drive side is always
considered as the side opposite the
fan inlet. Direction of discharge is
determined per diagrams shown.
Angle of discharge is referred to the
vertical axis of the fan and designated
in degrees.
All dimensions in inches.

380V/3Ph/50Hz motors are available. On horsepowers less than 1, motor frame sizes may change due to variations in voltage, special features, and motor manufacturer.
Motors shown are ball bearing, continuous duty, 1750 RPM or 1750/1140 RPM for two speed, two winding motors.

DRIVE LOSS
(% MOTOR POWER OUTPUT)
The AMCA Review Committee has developed the chart
shown below for the purpose of estimating belt drive losses.
To calculate total BHP (including drive losses): Find the
BHP of your operating point on the x‑axis on the graph
below. Follow the vertical line to the curves indicating
the range of drive losses. Look at the y-axis on the left
and find the drive loss percentage. Calculate the total BHP
by adding the drive loss to the operating point BHP.
For BHP’s below 0.3, use 30%.

Range drive loss for standard belts. Higher fan speeds
tend to have higher drive losses than lower fan speeds
at the same horsepower.
For totally enclosed, explosion proof, multi-speed and all 1.0 Service Factor
motors, fan BHP plus drive losses should not exceed motor rated HP.

The values of full-load currents, shown on the left, are for
motors running at usual speeds and motors with normal torque
characteristics. Motors built for especially low speeds or high
torques may have higher full-load currents, and multi-speed
motors will have full-load current varying with speed, in which
case the nameplate current ratings shall be used.
The voltages listed are rated motor voltages. The currents listed
shall be permitted for system voltage ranges of 110 to 120 and
230 to 240 volts.
The table data shown on the left is from the NEC 2005 edition,

The values of full-load currents, shown on the left, are typical for
motors running at speeds usual for belted motors and motors
with normal torque characteristics. Motors built for low speeds
(1200 RPM or less) or high torques may require more running
current, and multi-speed motors will have full-load current
varying with speed, in which case the nameplate current ratings
shall be used.
The voltages listed are rated motor voltages. The currents listed
shall be permitted for system voltage ranges of 230 to 240 and
440 to 480 volts.
The table data shown on the left is from the NEC 2005
edition, table 430-150.
The amperages given here are approximate values only and represent averages compiled from the tables of leading motor
manufacturers. Overload relay heaters should not be selected on the basis of these tables only. Heaters must be selected in
accordance with the actual motor current as shown on the nameplate. It is also important that ambient temperatures of the area in
which the motor control is located be taken into consideration when making heater selections. Ambient compensated overload relays
are available for abnormal temperature conditions.
On most Belt Drive YORK® by Johnson Controls roof exhausters, the motor synchronous speed is 1800 RPM.

YORK® GENERAL PURPOSE CENTRIFUGAL FAN, MODEL US
SOUND POWER LEVELS, SONE RATINGS, & SOUND CLASSIFICATION GUIDE
Sound Power Levels
Since any mechanical device generates some sound energy into
the air, fans will create some noise. Because of the great number
of factors influencing sound output it is invalid to compare fans
based on RPM, tip speed or outlet velocity. The only accurate
basis of comparison is the sound power level generated by the
fan at the required point of operation.
Having sound power levels for a specific fan at a specific
operating point allows the system designer to determine the
theoretical sound pressure level at any point in the occupied
space. AMCA Publication 303 and the ASHRAE Guides provide
more information on this process. Another typical application
of sound power levels is to compare similar fans. Generally
differences of 6 dB in the 63 Hz band and 3 dB in all other bands
are considered insignificant.
System designers use many methods to predict acoustic
acceptability of an occupied space.
The A‑weighted sound pressure level provides a single number
that corresponds well to the human judgement of relative
loudness. OSHA bases their requirements regarding exposure
to noise on A‑weighted sound pressure levels. The disadvantage
of this method is that A-weighted sound pressure levels do not
provide information as to the quality of the sound. Noise Criteria
(NC) curves are also widely used. To determine the NC level,
the sound power spectrum is compared to defined limits. Other
methods include RC curves, Sones, SIL and Noise Rating
Curves.
Each method relies on sound pressure level information because
the human ear “hears” sound pressure fluctuations, not sound
power (watts). Sound pressure is a function of the attenuation
of the space and the distance from the source. Consider a 100
watt light bulb. It provides adequate light for a closet, but not
for a classroom, and in a stadium it would be imperceptible.
While the light source was the same power (100 watts), the
brightness level changed dramatically. Similarly, the same sound
power level (acoustical energy) produces greatly different sound
pressure levels (noise).
Sone Ratings
YORK® by Johnson Controls has provided sone ratings to allow
designers to make an educated judgment as to the noise level
a fan will develop in a space. Sone ratings are a loudness index
developed from sound power level data. The calculation is at 5’
from the fan inlet and in front of a reflecting plane (hard wall).
Sones are weighted similarly to the A-weighting scale in that
more weight is given to frequencies that people can hear “well”
and less weight to frequencies that people do not hear “well”. A
significant feature of the sone scale is that it is linear rather than
logarithmic. This means that 40 sones is 33% louder than 30
sones, as opposed to 40 dB being twice as loud as 30 dB.
Since the sone rating is determined from well defined assumptions
and is linear in nature, it is ideal for comparing different fans
moving air at the same CFM and SP. When using sones for this
purpose, differences of 3 sones are considered negligible. The
suggested loudness level chart below is a practical guideline for
acceptable installed performance.
The sone values shown in this catalog are based on the sound
power levels determined above, and calculated in accordance
with AMCA Standard 301 “Methods for Calculating Fan Sound
Ratings from Laboratory Test Data.”

junction box, and drain connection leading into a grease collector/
separator box. If specified (heat and smoke removal option), fan
shall additionally provide UL power ventilator for smoke control
systems listing rated for 500°F at 4-hours and 1000°F at 41
minutes, including a steel wheel.
The bearing supports shall be constructed of welded structural
steel members to prevent vibration and rigidly support the shaft
and bearings, bearings shall be heavy duty, self-aligning, pillow
block ball bearings, grease lubricated and selected for minimum
life (L50) of 200,000 hours at maximum operating speed. Shafts
shall be turned, ground, and polished. Shafts shall be sized so
the first critical speed is at least 20% over the maximum operating
speed. Close tolerances shall be maintained along the length of
the shaft.
The standard fan wheel shall be aluminum (steel for smoke
removal), non-overloading backward inclined type. The wheels
shall be statically and dynamically balanced. The wheel and inlet
shall be aerodynamically designed and constructed to provide
maximum performance and efficiency.
Steel Wheel (Heat and Smoke Removal) - The wheel is a standard
duty, all-welded wheel. The blades are curved for improved air
performance, while increasing their strength and rigidity. The
wheel assembly is fully welded to provide extremely durable and
consistent performance. The wheel is dynamically balanced.
Balancing weights are mechanically attached to the inside of the
rims of both the backplate and wheel inlet. This allows a precise
placement of the weights anywhere within a full 360° range on
two separate planes, without the possibility of detachment
Pulleys shall be adjustable (through 20 HP) cast iron, machined,
keyed, and securely attached. Belts and pulleys shall be sized
for 150% of the installed motor horsepower. Motors shall be
heavy duty, ball bearing, open drip proof (totally enclosed or
other type if specified) motors. After assembly, the entire unit,
with drive train installed and set to specified RPM, shall have
a computerized vibration analysis performed. Vibration shall be
measured in the horizontal, vertical, and axial directions at each
bearing to assure quality and smooth operation.
Fans shall be licensed to bear the AMCA Air and Sound Certified
Ratings Seal. Fan air performance ratings shall be bear on test
conducted in an AMCA registered laboratory for AMCA 210 air
performance testing. The test standard used shall be ANSI/
AMCA Standard 210-85, ANSI/ASHRAE Standard 51-1985
“Laboratory Methods of Testing Fans for Rating.” All sizes must
be tested, calculations to other sizes not acceptable. Fan sound
performance shall be based on tests conducted in an AMCA
registered laboratory for AMCA 300 Sound Performance Testing.
