Explosion Isolation Valve

Camfil Air Pollution Control has introduced an explosion isolation valve that isolates dust collector explosions to prevent a deflagration from traveling back through the inlet pipe of the dust collector into the workspace.

Camfil APC Stinger Explosion Isolation ValveCamfil Air Pollution Control has introduced the Stinger™, an explosion isolation valve that isolates dust collector explosions to prevent a deflagration from traveling back through the inlet pipe of the dust collector into the workspace. Following extensive testing, Camfil APC reports that the Stinger is the first U.S.-made explosion flap valve to be certified by an independent testing agency to comply with NFPA standards.  It may be retrofitted onto most dust collection systems and used with new or existing Farr Gold Series® dust collectors where the risk of a combustible dust explosion exists.

A key feature of the Stinger valve is a lightweight, patent-pending composite blade that reacts with the highest possible speed in the event of an explosion. It closes faster than heavier steel blades typically used for dust collector inlet protection. Because of its light weight, less pressure drop is needed to hold the blade open during normal flow, saving on energy use. Also, the composite material has a smooth surface and does not use stiffeners which can allow dust to build up on the blade to compromise performance.
