Intelli-Sense™ Multi-Speed PVC Blowers handle extremely corrosive atmospheres produced by high order oxidizers such as perchloric acid

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 have a drain connection on the lower portion of the housing so that a washdown system can be utilized. Housings are vacuum formed from unplasticized Type I polyvinyl chloride for complete corrosion protection. Impellers made of injection molded PVDF resist highly corrosive atmospheres, operate quietly and provide optimum delivery. Powder-coated base and weather cover provide long life in extreme weather.
