These neoprene-coated fiberglass duct hoses have smooth liners that provide maximum airflow and minimize friction loss. Neoprene-coated fiberglass duct hoses blow or exhaust hot air in applications such as pellet drying, pre-launch fuel venting, and Lav waste fume removal. These lightweight, flexible hoses are flame-retardant and self-extinguishing. They handle fumes at low pressures and moderately high temperatures, but they are not recommended for applications with continuous flexing, liquids, or abrasives.

Neoprene-coated polyester duct hoses are used to blow or exhaust air for dehumidification, enclosed space ventilation, portable air conditioner, preconditioned air, and general ventilation applications in foundries, municipalities, shipyards, and the aerospace and facility-service industries. These flexible hoses are flame-retardant and self-extinguishing. They 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 fiberglass duct hoses have been coated with PVC (polyvinyl chloride). They are used to blow or exhaust low volumes of cool and warm air in general fume-removal and welding fume-removal applications in the metal-processing and shipyard industries. They are also well suited for ventilating photo-reproduction machines and fine-dust collection systems. These flexible hoses are flame-retardant and self-extinguishing. They also resist damage from exposure to UV rays and ozone.

These thermoplastic rubber duct hoses are reinforced with a wire helix that provides strength and durability, preventing collapsing or kinking under pressure or vacuum. They are used for fume-removal and dust-collection applications in the facility-service and municipal industries. These hoses provide excellent crush resistance and resist abrasion, chemicals, moisture, ozone, and UV rays.
