About BACKWARD INCLINED & AIRFOIL CENTRIFUGAL FANS
Wheel Specifications
BOTH BACKWARD INCLINED AND AIRFOIL FANS ARE NON-OVERLOADING TO FREE DELIVERY.
Each wheel type has backward sloping blades that are recognized as the most efficient blade orientation in the industry. These highly efficient wheel designs reduce energy consumption and have significantly lower noise levels than other fan types.
Type B Backward Inclined
Wheels utilize heavy gauge, flat, backwardly inclined blades. The wheel performs to high efficiencies at relatively low tip speeds, maintaining smooth, quiet operation. Easily made of special alloys. Standard catalog sizes range from 122 (12.25” Dia.) to 982 (98.25” Dia.), with custom sizes available.
Maximum flow (ACFM): 600–450,000 SWSI / 1,200–800,000 DWDI
Maximum pressure: 26 in. wg
Maximum temperature: 1,200ºF
Static efficiency: 80%
Material handling: None to dry & very light particulates
Type A Airfoil
Wheels utilize hollow double-thickness airfoil blades. The blade splits airflow, creating a smooth flow over the entire blade surface. Similar to Type B but operating at slightly higher speeds while consuming less horsepower. Standard catalog sizes range from 182 (18.25” Dia.) to 982 (98.25” Dia.), with custom sizes available.
Maximum flow (ACFM): 1,600–375,000 SWSI / 2,400–675,000 DWDI
Maximum pressure: 24 in. wg
Maximum temperature: 1,000ºF
Static efficiency: 82%
Material handling: None to dry & very light particulates

BACKWARD INCLINED & AIRFOIL CENTRIFUGAL FANS
One of the most popular choices of IAP products fulfilling many industrial performance requirements with high efficiencies at economical prices.
Backward Inclined (Type ‘B’) and Airfoil (Type ‘A’) fans utilize the same continuously welded heavy gauge housings, spun inlet cones & wheel shrouds, plate steel pedestals and structural steel bases. This attention to robust construction is coupled with engineered blade profiles and housing scrolls for highly efficient air movement at low to moderate pressures. Both fan types are available in single (SWSI) and double (DWDI) width and inlet!
