Recommended for low to moderately corrosive applications
Intelli-Sense Multi-Speed Blowers are weatherized, direct drive, non-explosion-proof blowers controlled by a two or three position switch. Each blower has a reliable electronically commutated motor (ECM), which consumes one third less energy and is easier and less expensive to maintain than beltdrive motors.
Intelli-Sense Blowers take much of the guesswork out of blower selection. Since they are adjustable over a broad airflow range, they may be used to exhaust fume hoods from 3' to 7' in width at full sash open height and 100 fpm face velocity. The blowers may also be used with hoods from 8' to 16' in width with reduced air volume modifications. As needs change, the blower settings may be adjusted to accommodate new airflow requirements.
