Upblast centrifugal exhaust with a direct motor to eliminate belt losses. Opt for our Vari-Green motor for the ultimate in efficiency.
An aluminum, backward-inclined centrifugal wheel generates high-efficiency and minimal sound. Matched to the venturi for maximum efficiency, each wheel is robotically welded and statically and dynamically balanced for long life and quiet operation.
NEMA-1 disconnect switch is factory mounted and wiring is provided from the motor as standard (other switches are available)
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
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].
Motor is carefully matched to the fan load and mounted out of the airstream to avoid crease build up
Motor cover is constructed of aluminum with stainless steel fasteners attached for easy removal and access to the motor compartment and drive assembly
Stainless steel fasteners allow for easy removal and access to the motor compartment and drive assembly
Cooling fins draw outside air directly into the motor compartment; this positive motor cooling with fresh air results in maximum motor life
Select models have various lifting points located on the drive frame or bearing plates
True vibration isolators contain two independent studs with rubber neoprene to support the drive assembly and wheel for long life and quiet Simple system operation—no steel-on-steel contact
Select the Accurex Vari-Green motor with integrated balancing pot or add our low cost speed controller to quickly balance your system at start-up
One-piece, heavy-gauge aluminum windband, with a rolled bead for extra strength, directs exhaust air away from the mounting surface
One-piece windband is continuously welded to the curb cap and drain trough for grease leak-proof protection
Aluminum curb cap has pre-punched mounting holes to ensure correct attachment to the roof curb
The drain-trough allows for one-point drainage of water, grease and other residue
