We manufacture Fab-Tech PermaShield™ Duct, a revolutionary hybrid fluoropolymer coated stainless steel duct system recognized worldwide as the premier solution for corrosive and hazardous fume exhaust needs. PermaShield is a fully engineered, modular fume exhaust system that combines the reliability of stainless steel with the superior corrosion-resistance of Exential's proprietary fluoropolymer barrier coating. PermaShield duct carries a highly regarded FM 4922 approval, and is certified by a “0” flame spread rating and a smoke generation index of less than “20” according to ASTM E-84 tests. This means that PermaShield does not burn and will not generate meaningful smoke in the event of a facility fire.
