A line of chlorinated polyvinyl chloride (CPVC) duct fittings, blast gates, and dampers for use in ventilation systems offers standard sizes from 6-24 inches; custom sizes or variations can be fabricated with quick turnaround. According to the manufacturer, CPVC duct is resistant to most acids and alkalis and is FM 4910 approved and UL-94 rated due to its self-extinguishing properties that limit fire spread and smoke damage, which make CPVC ideal for use in ventilation systems in clean rooms or where corrosive exhaust is present. CPVC keeps its physical integrity in temperatures up to 200º F.
