Polyester vinyl laminate duct hoses are used to blow or exhaust air for dehumidification, enclosed space ventilation and fume-removal, portable air conditioner, preconditioned air, and general ventilation applications in foundries, municipalities, shipyards, and the aerospace and facility-service industries. These flexible hoses are lighter than neoprene-coated polyester hoses and provide positive pressure movement for air, dust, and fumes at low temperature ranges. They are flame-retardant and self-extinguishing, and they resist damage from oils, moisture, ozone, and UV rays. These hoses also have an external vinyl-coated wear strip that protects the hose from abrasion when dragged. The hoses are highly compressible, which saves space when transporting them.

These silicone-coated fiberglass duct hoses have PTFE liners that resist weather and chemicals. These duct hoses are used in applications that need to remove chemical fumes. The hoses resist UV exposure and weather damage and will not kink. They have a smooth interior that maximizes airflow through the hose and minimizes friction. These hoses are highly compressible, which saves space when transporting them. They are not recommended for use with liquids or abrasive materials.
