Product Details

Centrifugal Belt-Drive Upblast Exhaust Ventilators

• Wall mount applications Aluminum, backward-inclined, nonoverloading centrifugal wheel design NEMA 1 junction box located in motor enclosure Max. inlet air temp.: 300°F UL 762 Listed Restaurant Exhaust Appliances (YZHW)
Designed for use in restaurants, schools, commercial, and industrial applications to exhaust contaminated air from kitchen range hoods. 1-pc. rolled aluminum windband fully welded to the base creates a virtually leakproof seal between the ventilator and the mounting surface. Internal steel support braces; round mounting plate included. Motor, drive frame, and blower wheel are isolated from the mounting base by the use of independent neoprene studs—no metal-to-metal contact, greatly reducing overall noise. Motor compartment is isolated from the contaminated air stream and is cooled by outside air pulled in through an oversized breather tube by the spinning action of the wheel.
UL and C-UL Listed.
