EFFICIENCY OF AIRFOIL WHEEL vs. BACKWARD INCLINED WHEEL Airfoil wheels provide the highest efficiency of all centrifugal fan designs. The curve overlays at right comparing a CPAF-220 and a CPF-220 illustrates a % increase in static efficiency for the airfoil design versus the backward inclined design in the normal selection range. This benefit results in lower brake horsepower consumption and a reduction in sound levels of 2-6 dba. CPAF-220 CPF-220 2

Maximum RPM Reduction Factor 0% 2% 4% % 11% 1% 20% 30% Fan performance tables are developed using standard air which is 0 F., 29.92" barometric pressure and.0 Ibs. per cubic foot. Density changes resulting from temperature or barometric pressure variations (such as higher altitudes) must be corrected to standard conditions before selecting a fan based on standard performance data. Temperature and/or altitude conversion factors are used in making corrections to standard conditions. EXAMPLE: Select a belt driven CPAF fan to deliver 6300 at 8" SP at 200 F., and 000' altitude. STEP 1. From the table, conversion factor is 1.63. STEP 2. Correct static pressure is: 1.63 x 8" SP = 13.04" SP at standard conditions. STEP 3. Check CPAF catalog for 6300 at 13" SP. We select a belt driven CPAF-200. Class IIP at 3126 RPM and 1.89 BHP. STEP 4. Correct the BHP for the lighter air: 1.89 1.63 = 9. BHP. A HP motor will suffice at 200 F., and 000' but not at standard conditions. Special motor insulation may be required due to altitude. B

SPARK-RESISTANT CONSTRUCTION For AMCA Type A or B spark resistant construction, please contact your local Cincinnati Fan sales representative. Type C: Consists of aluminum inlet bell and aluminum plate on drive side of the fan. Maximum Temperature is the same as for high temperature construction below for each arrangement.! WARNING The use of aluminum or aluminum alloys in the presence of steel which has been allowed to rust requires 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 also does not protect against ignition of explosive gases caused by catastrophic failure or from any airstream material that may be present in a system.

R dimension refers to dimensions shown on page 22. At elevated temperatures, the maximum wheel speed must be derated per the high temperature deration factors listed on page 4. In some cases, the derated maximum wheel speed may be lower than the maximum shaft speed with extended shaft R (shown above). The lower of the two speeds prevails. All maximum shaft speeds are independent of temperature. All plug fans with extended shafts ( R dimension on page 22) include the highest class of wheel construction for each size.! DANGER All fans & blowers shown have rotating parts and pinch points. Severe personal injury can result if operated without guards. Stay away from rotating equipment unless it is disconnected from its power source. Read operating instructions.

TYPICAL APPLICATIONS Typical applications for plug fans include ovens, kilns and dryers, where the plug fan circulates the air inside the equipment to maintain even temperatures. In clean rooms, dust collectors and air handling units, they provide the air flow required to move air through the system. They are used in any system or equipment where a plenum, or a space between two walls, act as the fan housing. Plug fans can also be used with an actual fan housing inside the plenum. TYPICAL OVEN APPLICATION AIR HANDLER APPLICATION DUST COLLECTOR APPLICATION 6

TYPICAL MOUNTING CONFIGURATIONS Plug fans can be mounted to the side wall or ceiling of a plenum. A hole, slightly larger than the plug fan wheel diameter, must be provided in the plenum. When the plug fan is installed, the hole will be covered by the plug fan panel. If the plenum wall or ceiling is insulated, as in an oven or kiln, the plug fan can be provided with an insulated plug box having the same thickness, up to 6 inches, as the plenum wall or ceiling. In this case, the hole in the plenum walls would need to be just large enough to clear the dimensions of the insulated plug box. These two methods allow for the use of a completely assembled fan from Cincinnati Fan. An alternate mounting method is to provide a hole in the plenum wall slightly larger than the shaft diameter of the plug fan. The plug fan panel is mounted to the outside of the plenum and the fan wheel is then mounted onto the fan shaft from the inside of the plenum. In all mounting methods, the inlet bell for the plug fan wheel is mounted last to maintain the proper bell to wheel clearance. Mounting of a fan housing is sometimes also necessary. See optional housing mounting types shown on page 23. TYPICAL INSTALLATION CLEARANCE HOLE FOR WHEEL IN WALL TYPICAL INSTALLATION CLEARANCE HOLE FOR SHAFT IN WALL HOUSED INSTALLATION
