They are used for supply or exhaust applications in commercial, institutional, and industrial HVAC systems. At the heart of the unit is a computer designed, backward inclined, centrifugal wheel. This heavy duty non-overloading aluminum wheel (steel for heat and smoke removal) assures low noise and high efficiency performance. The fan wheel, venturi inlet, housing, and frame are engineered to provide maximum performance and reliability. Fan housings utilize heavy-gauge materials and employ welded construction. Motors and all drive components have been carefully engineered and tested for durability and performance. A wide range of accessories are available to meet various application requirements. Model US centrifugal blowers are designed and built to provide the end user with a highly efficient and extremely reliable air moving unit. These units offer many features as standard equipment that other manufacturers consider options. Each unit is fully assembled, factory set at the specified RPM, and test run prior to shipment.

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. 4 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. 5 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. Gasketed Access Door (Standard) Quick Release Door (Optional) Outlet Flange (Optional) Backdraft Damper (Optional) Weather Cover (Optional) Duct and Transition Companion Flange (Optional) Vibration and Isolation Mounts (Optional) Support Angles (Standard for D18 and Up) 6 Inlet Guard (Optional) Inlet Angle Flange (Standard) YORK® GENERAL PURPOSE CENTRIFUGAL FAN, MODEL US 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. 7 YORK® GENERAL PURPOSE CENTRIFUGAL FAN, MODEL US UNIPAK & UNIPAK FATRAP Curb Mounted Utility Set with Integral Inlet Box Unipak Fatrap Configuration Unipak Unipak Fatrap Includes all the features of the US blower PLUS Includes all the features of the US blower PLUS Integral Galvanized Curb Cap • Eliminates need for costly customized field fabricated transition. • Fully welded corners. • Pre-punched mounting holes.

Motors shown are ball bearing, continuous duty, 1750 RPM or 1750/1140 RPM for two speed, two winding motors. Belt Drive Losses 30 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%. 20 15 10 8 6 4 3 2 1.5 1 0.3 0.4 0.6 0.8 1 2 3 4 6 8 10 MOTOR POWER OUTPUT (BHP) 20 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.

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.

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. 13 YORK® GENERAL PURPOSE CENTRIFUGAL FAN, MODEL US US10 | BELT DRIVE 20 9.0 Do not select shaded area. 18 1/2 8 5/8 RPM BHP 7.0 11 1/4 12 7/8 3800 RPM 6.0 3600 RPM 11 1/4 28 3/8 3200 RPM 5.0 1 1/2 3000 RPM 4.0 2800 RPM 2600 RPM 2400 RPM 2200 RPM 2.0 2000 RPM 1800 RPM 1500 RPM 1.0 1200 RPM 800 RPM 0.0 0 400 800 15 1/2 P 1231 1385 1538 1692 1846 2000 2154 2308 2462 2615 2769 2923 3077 3231 H 800 900 1000 1100 1200 1300 1400 1500 1600 1700 1800 1900 2000 2100 1 3/4 HP H HP P 10 14 1200 1600 AIR FLOW - CFM Max BHP: (RPM/2485)3 .25” SP RPM 949 1063 1176 1291 1412 1537 1664 1793 1923 2055 2191 2325 2461 2598 2734 2871 3009 3146 3284 3422 BHP 0.056 0.076 0.100 0.130 0.169 0.219 0.278 0.348 0.429 0.524 0.634 0.759 0.900 1.059 1.234 1.429 1.645 1.880 2.138 2.419 2.25 SP " RPM 2179 2270 2358 2448 2541 2641 2743 2847 2958 3072 3188 3301 3414 3527 BHP 0.579 0.671 0.779 0.900 1.032 1.174 1.330 1.502 1.668 1.846 2.041 2.247 2.468 2.704 2000 BHP 0.089 0.119 0.155 0.193 0.237 0.289 0.349 0.418 0.503 0.603 0.716 0.844 0.987 1.147 1.324 1.523 1.743 1.984 2.247 2.533 2.50” SP RPM 2265 2348 2438 2526 2617 2713 2814 2916 3021 3134 3248 3364 3477 3589 2400 2800 Outlet Area: 0.65 Sq.

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.” Sound Classification Guide Suggested Loudness Level Area Sone Levels Noise Criteria NC dBA (1) Up to 9 32 to 54 35 to 60 Bingo Hall, Auction Room, Hotel Ballroom, Social Club, Reception Room, Apartment House, Professional Office, Supervisor Office, Courtroom, School and Classroom, Hospital Ward, Operating Room, Correction Facility.

Fans shall be single inlet, single width, AMCA arrangement 10 with clockwise (or CCW) rotation. Air discharge position shall be THD unless specified otherwise. Fan housing shall be heavy gauge galvanized steel for maximum corrosion protection. Housings shall be field rotatable to any of eight 45° incremental air discharge positions. Fan scrolls shall be equipped with a bolted, gasketed (quick release if specified) access door for cleaning and inspection. The test standard 300 “Reverberant Room Method for Sound Testing of Fans.” All sizes must be tested, calculations to other sizes are not acceptable, Air or Sound tests results are to be made available upon request. Fans shall be UL (UL Std. 705, UL Std. 762 optional) listed. If specified (Fatrap option), fan shall additionally provide UL 762 Listing rated at 500ºF, motor pre-wired to a weather-proof 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.
