Backblast Dampers Isolate Explosion or Fire
Backblast dampers from Air Purifiers, Inc. provide a way to automatically and immediately isolate any occurrence of explosion or fire, preventing energy from returning back through the ductwork to the building or work area and meeting NFPA standards for dust collector safety.
Available in various diameters, our CARZ Explosion Isolation Flap is constructed of materials light enough to respond in milliseconds, yet strong enough to withstand the pressure of an explosion.
The flap is designed to open whenever there is normal airflow in the duct. The damper offers protection by both preventing the effects of a dust explosion from spreading, and also by preventing stray dust from returning along the duct when the dust collector is stopped.
