Type C Fan shall be so constructed that a shift of the wheel or shaft will not permit two ferrous parts of the fan to rub or strike. Corrosion Resistant & Special Alloys For applications involving handling of corrosive fumes, a wide variety of protective coatings and special alloy metals are available. Consult your American Fan representative or factory for full details. Arrangements Arrangement 1 Arrangement 4 Arrangement 8 Arrangement 9 The fan wheel is overhung with both bearings mounted on a common pedestal. Arrangement 1 is suitable for high temperature and/or corrosive environment. Fan can be belt driven or directly coupled to drive motor mounted on a separate base. Direct drive fan with wheel mounted directly on motor shaft. Unit is designed for standard temperature applications only. With no belt loss, the direct drive fan operates at a higher efficiency. Direct drive fan through shaft and bearings. Efficiency of Arrangement 4 is maintained. However, Arrangement 8 may be used for high temperature and/or corrosive applications that require the motor shaft to be outside of airstream. The fan wheel is overhung with both bearings mounted on a common pedestal. Fan belt is driven with drive motor mounted on bearing pedestal for a more compact unit suitable for high temperature and/or corrosive environment. Maximum Motor Frame Sizes Arrangement 1 Unitary American Fan Co. offers unitary bases constructed of heavy channel iron for high horsepower or high temperature applications where Arrangement 9 is impractical. The unitary base design is a complete packaged unit simplifying handling and installation while providing a more uniform weight distribution necessary when vibration isolators are used. Unitary bases also allow excellent access for routine maintenance. FAN SIZE ARR T 1 UNITARY ARR T 4 ARR T 8 ARR T 9 STD. BASE ARR T 9 EXT.

5 Temperature & Altitude Corrections Using Density Correction Factors The capacity tables in this bulletin are based on fans handling standard air at a density of.7 pounds per cubic foot equivalent to air at 7 F and 9.9" Hg barometric pressure. Therefore, when a fan handles air or other gases at other than standard density due to temperature, altitude or the types of gas, the published tables should be used in the following manner. Example Select a Turbo Pressure Blower with a VP wheel for 16 1 oz. SP F and ' elevation. 1. Determine the equivalent static pressure in the following manner: SP = required SP x density factor for conditions from the table below, ie., equivalent SP = 1 x 1. = 18 oz. SP.. Using the required A and the equivalent SP, select a VP blower from the quick selection table, ie., Model VP-3-8-1A with a of Correct for operating conditions by dividing from the table by density factor, i.e., 13.8 = 8.7 at conditions. 1. AIR TEMP. ALTITUDE IN FEET ABOVE SEA LEVEL DEG. F

6 Blower Selection Instructions 1. Based on application, determine which wheel type(s) would be appropriate. Example: Select blower for 17." SP, Clear air, 7 F. See BC Wheels.. Using the required and SP (equivalent SP if density is other than.7lbs./ft.) Choose a model from quick selection chart that is nearest your requirement. Note the Model No. and Curve No. Example: From BC A produces 17.3" SP, 3.9, Curve No.. 3. Refer to the appropriate curve no. to determine exact and at required SP. Read across grid at required SP until line intersects curve. Read Scale straight down point of intersection. Example: 17." SP intersects curve at Where line intersects curve, read straight across to right on the scale. Example: 89 intersects curve at 3.9. HP motor is required.. Find numbered point on curve nearest selection point and locate corresponding sound analysis point in sound analysis chart, interpolating when necessary. Example: Selection point is approximately equidistant from points 6 and 7. Referring to sound analysis chart on page, sound analysis of points 6 and 7 is: TD-/ BC-1 6", " OUTLET 34 RPM,.7 IV = /.1963, OV = /.1364 IV = VELOCITY OV = OUTLET VELOCITY = BC A = BC A 1 63% 8% BC A Interpolating for selection PT >

10 Performance Curves & Sound Data Note: All Octave band (Hz) readings shown in charts are sound power (PWL x 1 watts). The levels shown were obtained in American Fan Company s semi-reverberant laboratory with open inlet and ducted outlet to within the laboratory. Because sound pressure varies depending on surroundings and system, values obtained from your installation may be different. Reductions of levels is also possible if blower is ducted on the inlet and/or outlet. levels shown are intended for comparative purposes only.
