PureGuard II


PureGuard II™ Fluoropolymer Coated Stainless Steel Duct

PureGuard II DuctPureGuard II ™ is our welded stainless steel exhaust duct system coated with our proprietary hybrid fluoropolymer PureGuard coating.  Our combination of welded stainless substrate and proprietary PureGuard coating satisfied all testing requirements necessary to gain Factory Mutual standard 4922 approval for corrosive fume and smoke exhaust without sprinklers.  Additionally PureGuard II is approved by Factory Mutual for installation in clean rooms.

Developed from years of experience, our PureGuard coating provides the best corrosion prevention available in the coated duct market today. Along with excellent corrosion protection, PureGuard also provides excellent flame spread resistance and limited smoke generation. 

The bonding of the fluoropolymer coating to the stainless steel substrate is what makes our product a frontrunner in our marketplace.  To date we have never experienced a reported failure of a PureGuard II product, making PureGuard II a name you can truly rely on. This coating is also proven to not spread fire while providing years of maintenance free operation in your facility.
