Poly Vinyl Duct (PVS/PCD) Products

PCD Polyvinyl Coated Ductwork For Underground Air Ducts and Fume Exhaust Systems

Some manufacturers refer to PCD As PVS. Both are basically the same and work identically.

What is PCD?

The PCD manufacturing process begins with (1) prime, hot-dipped galvanized steel that is cleaned and fire treated. Then (2) a special epoxy primer is bonded to both sides of the metal. Finally, (3) a 4-mil polyvinyl coating is heat-fused to one side (4 x 1) or both sides (4 x 4).

PCD is used for underground ductwork and as an alternative to the use of stainless steel in fume exhaust systems.

4 x 1 PCD For Underground Duct Systems
4 x 1 PCD has the 4 mils of polyvinyl coating on the outside to provide protection against corrosion from the soil. (For fume exhaust PCD, see the last page of this brochure.)

By combining the strength of steel and the chemical inertness of plastic, PCD Ductwork is both lightweight and corrosion and weather-resistant. PCD will not rust, chip, crack, peel, corrode or produce odors. Although light in weight, PCD Ductwork is strong enough to walk on and will not collapse under concrete.

4 x 4 PCD For Fume Exhaust Systems PCD is an ideal material for many fume exhaust applications. Combining the strength of steel with the chemical inertness of plastic PCD offers completely integrated systems with diameters from 4” – 60” spiral pipe and all standard and special fittings that may be required. The assembly of the system is completed by the use of PCD duct sealer, PCD tape and stainless steel screws.

TEMPERATURES Practical usage range is from -30°F to 200°F.

LIMITATIONS – (See PVS lab test data at the back of this catalog) PCD has been used with great success for many major exhaust systems. However, it is up to the user to determine the suitability of PCD for any particular job. Samples will be provided upon request.
