Intelli-Sense™ Multi-Speed Fiberglass Blowers are ideal for fume hood exhaust systems in moderate to highly corrosive conditions

They feature a direct drive ECM motor, which consumes one third less energy and is easier and less expensive to maintain than belt drive motors, and a phenolic-coated impeller and housing. Unit comes with control box and 3 speed blower switch. Adjustable over broad range of airflows.

The Intelli-Sense Blower provides an economical alternative to traditional on/off blowers. Users may close the sash and turn the Intelli-Sense Blower switch to standby mode so that the hood operates at a lower velocity yet fulfills minimum air exchange requirements. Lower velocity modes have the added benefit of quieter operation than full velocity mode.

They are not recommended for use with perchloric acid. Housings are made from molded fiberglass reinforced polyester for durability and long life. Balanced, forward-curved impellers made of injection-molded polypropylene resist corrosive atmospheres, operate quietly and provide optimum air delivery. Powder-coated base and weather cover provide long life in extreme weather.
