The Series 59 Fiberglass Direct Drive Wall Ventilators are designed for general ventilation where corrosive elements exist in fume or vapor form. The units are manufactured out of solid fiberglass and designed to pass through a framed-up wall opening as a complete assembly, either by itself or with accessories.
Hartzell Wall Ventilators utilize a highly efficient, one-piece, solid-fiberglass, airfoil-type propeller from an RTM mold. The fan housing incorporates the Hartzell Air Seal, which allows the orifice ring to overlap the propeller tips. This practically eliminates backflow of air and increases efficiency by 10% or more. AMCA-certified for air performance, Series 59 Fans are available in sizes 12 to 60″ with flow rates from 1,315 to 55,500 CFM at free air.
