Explosion Isolation Flap

Explosion Isolation Flap Type CARZ

The CARZ Explosion Isolation flap prevents the devastating effects of a pressure wave and flame front, from a dust explosion downstream, from traveling back along the duct which it is fitted. It is effective up to a maximum declared reduced explosion pressure within the protected enclosure (typically ATEX Zone 20 internally) and acts as an isolating valve during the explosion. In normal operating mode it is held open against gravity by the dust laden air stream flowing in the direction opposite to that of the explosion pressure wave.
