With its...

CHICAGO AIRFOIL WHEEL The airfoil blade is recognized as the industry’s most efficient and quietest design, creating a smooth lifting airflow 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. Wheels are constructed of stitch welded high strength steel with keyed straight bore. Continuously welded construction is also available. Wheels are statically and dynamically balanced. REDUCED ENERGY COSTS Because the airfoil blade glides through the air with less turbulence, the fan...

HOUSINGS Housings are fabricated from heavy gauge steel. They are suitable for CW or CCW rotation as inlet cones are mounted on both sides. Sizes 445 and 490 include welded stiffeners, INLET CONES Full width cones are used with either full width housings or no housing as an open wheel installation. The cone is held to the housing with flat washers to facilitate proper positioning. A 72% cone is needed for 72% housings, or the cone can be used with no housing. INLET VOLUME CONTROLS The Inlet Volume Control (IVC) is ideal for variable volume systems. It provides more economical performance...

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". Closed Plenum...

Fan capacity tables are based on standard air at 70°F and sea level. For other operating conditions, correct the required Static Pressure (SP) before using the rating tables. Brake Horsepower (BHP) is corrected after the fan selection has been made. EXAMPLE: Select a D/62 fan kit to handle 5500 CFM at 2" SP, 120°F and 1500 feet above sea level. 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: TABLE r - Temperature and Altitude Correction EXAMPLE: Size 150 fan...
