EFFICIENCY OF AIRFOIL WHEELS vs. BACKWARD INCLINED WHEEL Airfoil wheels provide the highest efficiency of all centrifugal fan designs. The curve overlays at right comparing an SQAF-220 and SQBI-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. SQAF-220 SQBI-220 ADVANTAGES OF DIRECT DRIVE ARRANGEMENT #4 COST Lower initial cost plus lower maintenance cost (no v-belt drives, fan shaft or bearings to replace). RATINGS More ratings available. All sizes offered with two wheel diameters and fan housing widths from 0% to 0% in % increments. COMPACT Requires less space. MOUNTINGS Four discharge positions and two rotations (CW or CCW) plus fans can be mounted horizontally (Maximum 600 pound motor). LESS WEIGHT Requires less supporting structure. CONSTRUCTION Solidly built with continuously welded housings and mounting holes in all support flanges. All fans are mechanically run tested prior to shipment to ensure the balance of the assembled unit. 3

SPARK-RESISTANT CONSTRUCTION For AMCA Type A or B spark resistant construction, please contact our 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. HIGH TEMPERATURE CONSTRUCTION Standard Construction: Arrangement 9 suitable to 300 F. (149 C.) Arrangement 4 suitable to 200 F. (93 C.) 301-400 F. ( -204 C.)

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 SQAF fan to deliver 00 at 8" SP at 200 F., and 000 feet 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 00 at 13" SP. We select a belt driven SQAF-220, Class III at 24 RPM and 21.9 BHP. STEP 4. Correct the BHP for the lighter air: 21.9 1.63 = 13.3 BHP. A 1 HP motor will suffice at 200 F., and 000' but not at standard conditions. Special motor insulation may be required due to altitude.
