Pure Guard SS

Why the best?

• Pure Guard SS has the thickest corrosion liner in the industry (for FM Approved products, by far)
• Pure Guard SS has the best flame performance – the only FM Approved duct that did not ignite in the FM 4910 (Clean Room Protocol) battery of tests.
• Pure Guard SS has unlimited height approval without the use of internal sprinklers
• Pure Guard SS comes standard in up to 10 ft (3m) lengths, eliminating up to 20% of your handling and flange joint leak paths.
