Non Insulated

Air Ducts

Non-insulated UL181 Class 1 flexible air duct, extremely strong with doucle laminated polyster film permanently bonded to a corrosion resistant spring steel wire helix, for all pressure heating and cooling systems. A superior alternative in applications where insulated duct is not required or cannot be used, e.g., clean room applications. Unlike connector-rated products, is not limited to length of run.
