2Pages

Use The BEF is designed to provide movement of air in exhaust and air supply systems. Suitable uses include comfort ventilation, make-up air for laundry and mechanical rooms, and exhaust and air supply in kitchens/bathrooms/laundries in multi-story, multifamily buildings. Description The BEF is a highly efficient box ventilator with an electronically commutated permanent magnet motor, that uses a backward curved centrifugal impeller to provide high capacity at a high static pressure. The ventilator cannot be used for transport of large particles. The fan is designed to exhaust lint-laden air from single or multiple Type I and Type II residential and commercial clothes dryers. It can be installed indoors as well as outdoors. The design meets Type B, Spark Resistant Construction, and is completely insulated against fire, noise, condensation and heat with 2" fiberglass insulation. A service door is provided to allow easy access to the impeller. The unique design allows the fan to be oriented in multiple positions, standing on a flat surface or suspended from a ceiling. It can be installed indoors as well as outdoors. The box ventilator can operate with exhaust temperatures within 10°F (-12°C) and 400°F (200°C), and at ambient temperatures within -20°F (-30°C) and 120°F (50°C). Material The ventilator housing is galvanized steel while the impeller is welded aluminum.* The aluminum impeller is statically and dynamically balanced with permanently attached balancing weights. * Stainless steel housing and impeller optional Motor The motor is a TEFC air cooled, maintenance-free variable speed permanent magnet motor with pre-lubricated and sealed ball bearings and a Class H temperature rating. The motor with controller is rated at 92% efficiency and able to operate as low as 50 RPM. It has integrated protection against overloading, blocking over and under voltage and over-heating. The motor shaft in internally isolated to eliminate the need for external shaft grounding. It is rated for outdoor installation. The included EDrive motor control (NEMA4X) is factory programmed by ENERVEX for optimal operation of the ventilator.
