Standard Models: Portable blower / exhauster with turbine blades to deliver a constant source of clean air in even the most difficult to ventilate conditions. These rugged industrial blowers have corrosion and chemical resistant ABS (Acrylonitrile Butadiene Styrene copolymer) housings, cast aluminum turbine fan blades and heavy duty cycle switched motors. Anti-static intrinsically safe models are recommended for use in hazardous atmospheres containing explosive and combustible gases and vapors.
