PVC Ductwork

Polyvinyl Coated Ductwork (PVC duct) brings together the strength and durability of steel along with the corrosion resistance of polyvinyl chloride. This makes PVC duct perfect for underground air delivery and fume exhaust applications.

At Hranec Corporation, we take a leading role in designing and fabricating your PVC air ducts. Download our Catalog, or contact Hranec today to learn more.

Advantages of PVC Duct

PVC ductwork has been used successfully in underground applications for more than 30 years. PVC duct is light, easy to maneuver on the job site, and can be cut with circular or saber saws (outfitted for metal cutting).

PCD Diagram PVC duct can be encased in concrete and requires no protection from the minerals and salts often found in backfill. It can be placed in direct contact with the soil, assuming proper drainage is employed to prevent standing water.

These are just a few of the advantages of using PVC ductwork in your underground applications. To talk to the experts and learn more, contact Hranec today.
