HRV Hooded Roof Ventilators

Description

HRV hooded roof ventilators are suitable for industrial supply or exhaust fan applications. They are ideal for a variety of applications, including general ventilation, moisture-laden air, heat or smoke fumes, and mild contaminates in the air stream. HRV hooded roof ventilators offer aerodynamically superior performance, constructed with a heavy duty welded steel base and aluminum hood with bird screen. These powerful industrial fans are available in diameters from 24″ through 60″. The adjustable pitch airfoil axial impeller is constructed of spark resistant die cast aluminum, and is factory set for precise performance matching. HRV hooded roof ventilators are available in either direct drive (HRVD) or belt drive (HRVB) configurations.
