Ventilation in Corrosive Atmospheres

Resolite's ResoFLO FRP gravity ventilation systems are designed to withstand the extremely corrosive environments often associated with pulp and paper mills, chemical plants, steel mills, metal treatment facilities, chlorine cell buildings, and wastewater treatment plants. Operating conditions at these types of industrial sites typically include deadly threats to building components, excess heat, moisture and corrosive gases, liquids and particulates. Working together, they can quickly destroy ordinary ventilation system components and impair critical production processes. Fiberglass reinforced polymer materials, with their excellent resistance to corrosive atmospheres, can substantially increase the service life of ventilation systems.

Resolite's ResoFLO Series (Stationary Blade and Adjustable Blade) FRP Louvers provide excellent corrosion resistance for industrial and commercial air intake or exhaust applications. The center pivot adjustable blade louvers and stationary blade louvers are custom fabricated to fit any size opening. Individual pultruded louver blades are mounted in strong, minimum 6" deep, pultruded FRP channel frames. Mullion covers are provided for multi-unit installations.
