Our insurance loss control was out last week and we got a clean bill except for the new DC we are installing. He is saying we need a high speed abort gate on the return air. Anyone have one or know what they are all about? I searched google and it looks like a huge monster!
(Dust Collection and Safety Equipment Forum)
From Curt Corum, forum technical advisor:
When required, they would be located on the return air duct from dust collector and prior to dust collector. In the event of a bag house explosion, diverts to outside instead of back into the building. Pyroguard has them from 4" diameter to 60" diameter.
