▪Aluminum, backward-inclined, nonoverloading centrifugal wheel design ▪NEMA 1 junction box ▪Max. inlet air temp.: 300°F ▪Air handling quality bearings meet min. L10-100,000 hr. ▪Bearings—units without drive package: sealed pillow block up to 16 1⁄2"

wheel dia., regreasable pillow block for 18 1⁄2" wheel dia. and larger ▪Bearings—assembled units: sealed pillow block up to 18 1⁄2" wheel dia.,

regreasable pillow block for 21 1⁄4" wheel dia. and larger ▪UL and C-UL 762 Listed Restaurant Exhaust Appliances Designed for use in restaurants, schools, and commercial and industrial applications to exhaust contaminated air from kitchen range hoods up and away from roof. 1-pc. rolled aluminum windband is fully welded to base for virtually leakproof seal between the ventilator and the mounting surface. Internal steel support braces and a fully rolled windband dramatically increase the rigidity of the ventilator. Motor, drive frame, and wheel are isolated from the mounting base by 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 that is pulled in through an oversized breather tube by the spinning action of the wheel. Performance certified is for installation type A: free inlet, free outlet. Power rating (BHP) does not include transmission losses. Performance ratings do not include the effects of appurtenances (accessories). The sound ratings shown are loudness values in fan sones at 5 ft. (1.5m) in a hemispherical free field calculated per AMCA Standard 301. Values shown are for installation type A: free inlet hemispherical sone levels. Drive package consists of appropriate motor, belts, and sheaves to obtain performance listed.

WARNING: Do not use a damper in any kitchen installation.
