PBCA

High efficiency backwardly inclined airfoil bladed wheel designed for clean, dry air applications, exhibiting non-overloading horsepower characteristics and stable performance over the entire pressure curve. Noise levels are the lowest in the peak efficiency range of the performance curve.

Class 3 wheels utilize internal blade stiffeners for higher tip speed and temperature capability.The Plug Fan eliminates the need for connecting duct work. Its mounting panel permits assembled-unit installation to any well-supported plenum wall.

PBCS

High efficiency backwardly inclined single thickness curved wheel has a blade shape similar to the convex shape of the BCA airfoil wheel. This shape provides nearly identical performance characteristics at a given speed at a slightly lower efficiency.

Designed for moist or lightly contaminated air systems, and exhibiting non-overloading horsepower characteristics and stable performance over the entire pressure curve. Noise levels are the lowest in the peak efficiency range of the performance curve.

Class 3 wheels utilize a circumferential blade stiffener for higher tip speed and temperature capability. 16 fan sizes from 12-1/4" through 54-1/4" diameter wheels, in Class I, II, III construction. The Plug Fan eliminates the need for connecting ductwork. Its mounting panel permits assembled-unit installation to any well-supported plenum wall.
