PVC & CPVC Dampers
- Sizes from 4" to 24" in PVC and CPVC
- Precision welded construction with fine tolerances
- Multiple types: Gravity, Butterfly, Blastgate options
Butterfly dampers for backdraft applications provide reliable airflow control in PVC and CPVC plastic ventilation systems. Precision-welded construction and fine tolerances support ductwork damping and industrial ventilation, while corrosion-resistant thermoplastic materials help manage harsh, chemical-laden gas streams in demanding facility environments.


A butterfly damper uses a rotating disc to regulate or stop airflow within a ventilation duct. In backdraft applications, it can help limit reverse airflow when the ventilation system is not operating. PVC and CPVC butterfly dampers are suited to plastic ventilation systems where corrosion resistance and compatibility with chemical-laden gas streams are important considerations.
