The Series 83 fiberglass belt drive downblast roof exhauster is a centrifugal industrial roof exhaust fan providing a low profile exhaust solution for roof and wall installations.
Featuring a resin-coated fiberglass construction, the Series 83 belt drive exhaust fan is ideal for general ventilation applications where concentrations of corrosive elements exceed the limits of standard fans. The fiberglass construction also offers advantages in terms of weight, strength and dimensional stability. Constructed for use in temperatures up to 125°F, Series 83 downblast exhausters feature a fiberglass housing and one-piece, solid fiberglass centrifugal FE wheel with backward curved blades for non-loading performance. All fiberglass surfaces are protected with a resin coating for superior protection from chemicals, flame, and ultraviolet light, and to provide smooth airflow. Airstream hardware is stainless steel, while structural airstream parts are fiberglass resin and epoxy-coated stainless steel.
Series 83 exhauster fans are available in sizes from 12 inches through 40 inches, supplied assembled and ready to install. Sizes 12-inch through 18-inch are available as either roof- or wall-mounted units, while larger sizes are roof-mounted units. All Series 83 exhauster fans are dynamically balanced at the factory before shipping. Accessories include special motors, disconnect switch, bird screen, fiberglass damper and more.
