PermaShield Fume Exhaust Duct

PermaShield combines the reliable strength of stainless steel, the superior corrosion resistant attributes of fluoropolymers and an array of innovative fittings to provide safe, reliable and clean corrosive fume exhaust systems. For new construction or facility renovations, consider the benefits of PermaShield duct.

PermaShield EZ Duct Clamp System

PermaShield duct systems can also accommodate even faster and easier installation with the EZ Clamp option. When you specify EZ for a system joint, companion angle rings with multiple fasteners are replaced with a single fastener and band style clamp.

Dampers & Blastgates

As your trusted partner for your next fume exhaust duct system, Exentec also offers a broad range of standard coated and uncoated airflow control devices or custom engineered and built devices for any damper configuration required.

Adapters & Accessories

Specialty adapters allow the transition from PermaShield duct to a wide range of threaded or other flanged duct systems. We also offer an extensive selection of accessories and flexible design capabilities including modular options, allowing our customers the ease of one stop shopping.
