In certain environments, like indoor swimming pools and saunas, textile mills, greenhouses and other agricultural facilities, wastewater treatment plants, aquariums, oil refineries, and more, centrifugal exhausters are charged with moving humid or corrosive air out of the building. These exhaust fans must be designed to withstand moisture and chemicals. 

That's where fiberglass exhaust fans come in. With molded fiberglass housings, these heavy-duty centrifugal fans offer corrosion resistance and high efficiency in challenging environments. Fiberglass fans are available in belt drive and direct drive models. 

At NorthStock, we maintain an extensive inventory of HVAC products, including fiberglass exhaust fans in dozens of models and sizes. Search by part number or browse our selection here:
