CHICAGO AIRFOIL WHEEL The airfoil blade is recognized as the industry’s most efficient and quietest design, creating a smooth lifting airllow over the entire surface of the blade. Chicago's airfoil wheel has a broad efficiency curve that offers a wide operating range with more selections from each fan size. Sizes 135 to 490 are available with Standard or Hi-Speed wheels, both constructed of continuously welded high strength steel with either keyed straight bore or with taper-lock bushing. Wheels are statically and dynamically balanced. AIRFOIL WHEEL TYPES Cast Aluminum Wheels Aluminum...

HOUSINGS Housings are fabricated from heavy gauge steel and can be welded or bolted to a panel wall When the plenum wall does not serve as a side cover, a drive side cover plate can be furnished. Sizes 100 through 402 are suitable for CW or CCW rotation as the inlet cone can be mounted on either side. Sizes 445 and 490 includes welded stiff eners and solid drive side sheet, available in CW or CCW rotation. INLET CONES 72% Width Housings Same as full width, except with the narrower housing the installation needs less plenum space and will use a correspondingly shorter fan shaft. A matching...

OPEN WHEEL DATA Turbulence is caused by sharp bends and abrupt area changes beyond the fan housing. This loss can be prevented by baffles or turning vanes. As an option, open wheel factors can be applied to compensate for the loss. Apply the following factors to Capacity in the performance tables and maintain a minimum clearance of one wheel radius between the wheel and the wall or walls of the discharge plenum. Open Wheel Factors CLOSED PLENUM • Fan Size refers to “nominal size" derived by adding a decimal point one place from the right. Example -122 = nominal size 12,2". PLENUM EFFECTS...

Fan capacity tables are based on standard air at 70°F and sea level. Correct the required Static Pressure (SP) before using the rating tables. The Brake Horsepower (BHP) is Corrected after the fan selection has been made. EXAMPLE: Select a D/62 fan kit to handle 2600 CFM at 3" SP, 300°F and at 1500 feet above sea level. TABLE I - Temperature and Altitude Correction RA Fan was specifically designed for improved efficiency and lower sound levels in low pressure, high volume applications. A typical example of an advantageous RA selection follows: EXAMPLE: A Size 150 fan with 5400 CFM at 1" SP,...
