JMD Poly-Vent Ducting is a filament-wound product manufactured through the combination of fiberglass roving, polyester resins, and flame-retardant additives. Its rigid design and smooth interior ensure that air flow will not be restricted, resulting in better ventilation at the working face. Our high-impact resin provides for exceptional strength and performance at a fraction of the weight of metal pipe and conduit. JMD Poly-Vent Ducting can be manufactured to meet almost any underground requirement. JMD offers a complete line of elbows, tees, wyes, reducers, slider, and damper sections. Our ducting is manufactured in both round and oval configurations. JMD's in-house engineering department is here to assist you with product selection, design, and installation.
