Fiberglass Centrifugal Roof Ventilator, Direct Drive
The FA 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 FA’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.
