Designed with flexibility in mind, every feature of the EP12ACP Ventilation Blower is designed to meet the confined space ventilation demands for many construction, utility, and municipal applications. Straight thru, axial flow design maximizes air flow delivery rates with input horsepower. Sturdy, easy-grip handle molded directly into the housing makes for convenient, reliable transport. The tough, double-walled housing is molded from UV-resistant polyethylene, making it dent-resistant, corrosion-proof and virtually indestructible. Air flows rates are certified by an independent testing agency.
