Ideal for fume hood exhaust systems in moderate to highly corrosive conditions.
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.
Features & Benefits
- 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
- Direct drive, UL listed, ECM motor uses one third less energy than belt drive motors
- Inlet and discharge diameters are sized to receive rigid PVC ducting material directly for easy installation
- Thermal override protection. RPM speeds are automatically reduced when motor is overloaded
- Flow-through vent holes and louvers allow air to circulate
- Speed control box included for mounting on top of customer-supplied fume hood and blower switch and label* for multiple speed operation
- When blower is properly installed to ductwork, sound levels range from 50 to 70 dba
- Variable exhaust orientation adjusts to eight outlet positions for installation flexibility (vertical discharge is recommended)
Models without control boxes are for use with Protector I-S Hoods ONLY. All other hoods require the blower with the control box.
