Belt drive, mixed-flow, inline exhauster with the motor, drives and bearings located outside the airstream. This design exceeds the efficiency of comparably sized tubular centrifugal and vaneaxial fans, resulting in lower motor horsepower requirements and lower operating costs.

Features

Housing

Heavy gauge, rolled steel construction and continuously welded to eliminate air leakage
Straightening vanes are welded to the housing to ensure maximum efficiency and strength
Standard coating is charcoal baked enamel

Access Door

Bolted, over-sized access door with gasketing for servicing

Mixed-Flow Wheel

Hybrid (centrifugal and axial) wheel
Wheels are made of welded, high-strength steel
Precision balanced for smooth, trouble-free operation
Non-overloading design for high efficiency and minimal sound.

Inlet

Streamlined inlet optimally matched to the impeller
