The ultimate in flexibility: commercial or industrial clean air intake, exhaust, return or make-up air.
The fan housing is constructed of rigid structural members and formed galvanized steel panels
Aluminum, backward-inclined, non-overloading, centrifugal wheel delivers maximum efficiency; each wheel is statically and dynamically balanced
Inlet and discharge duct collars are provided for easy duct connection
Square design provides a larger discharge area than tubular centrifugal and vane axial fans, so outlet velocities are reduced for quieter operation
Belt adjustment is accomplished by loosening fasteners, sliding motor plate and retightening fasteners.
Permanently lubricated, sealed ball bearing motors are selected to provide years of trouble-free operation with minimal maintenance
Bearings are 100% factory tested and designed specifically for air handling applications with a minimum L(10) life in excess of 100,000 hours [L(50) average life of 500,000 hours].
Drives are sized for a minimum of 150% of driven horsepower. Machined cast iron pulleys are factory set to the required RPM and adjustable for final system balancing. Belts are static-free and oil-resistant
Precisely sized, ground and polished so the first critical speed is at least 25% over the maximum operating speed
Close tolerances, where the shaft contacts bearings, results in longer bearing life
NEMA-1 disconnect switch is factory mounted and wiring is provided from the motor as standard. All wiring and electrical components comply with National Electric Codes and materials are UL Listed. Other NEMA enclosure disconnect switches are optional.
The cabinet construction features two side panels for easy access to all internal components
