Fiberglass Centrifugal Roof Ventilator, belt Driven


The FAB Fiberglass Roof Ventilator is specifically designed for the exhaust of moisture-laden, corrosive, or chemically contaminated air frequently associated with natatoriums, aquariums, indoor swimming pools, laboratories, and waste water treatment plants.

The FAB’s fiberglass housing is virtually impossible to dent, crack, or break and is resistant to weather, salt spray, and most chemicals. Fiberglass housings also absorb noise and vibration.
