Offered separately or as an integral component of our scrubber systems, our HEE-Duall brand custom fiberglass reinforced plastic (FRP) exhaust duct, hoods and stacks are an ideal and preferred method of venting in a variety of applications over traditional materials.
Our manufacturing process ensures uniform thickness and the highest quality finish, and we use premium quality resin and glass systems with rich resin interiors for corrosion resistance and fire retardant exteriors that are UV stabilized.
We manufacture both round and rectangular duct. Round duct is available in standard 3 to 144 inch diameters, with non-standard and rectangular sizes available which we design to suit your specific needs. Our duct and fittings are manufactured utilizing filament winding and hand lay-up techniques and comply with applicable ASTM (American Society for Testing and Materials) and National Bureau of Standards (NBS) standards.
