Air Handling


PolyFab provides:

Custom duct and air handling assemblies of all materials built to your design. We also offer rectangular and large cylindrical duct rolled from PVC, CPVC, Polypro, HDPE, and Kynar®. Our oven is 14 ft long inside so we can roll the largest pieces. Very large round duct is assembled from 2 pieces. We have a line bender that is 10 ft long so rectangular duct is no problem. We also fabricate all the special fittings you need to complete the system, including elbows, tees, reducing tees, no back-draft dampers, square to round transitions, offsets, and tapered reducers.
