self cleaning blast gate questions
Contributor. Join Date. Dec 2006. Location. Toronto Ontario. Posts. 11,270. I use the self cleaning blast gates, and yes there is some leakage, however to put it in perspective, on a 5" gate, the leakage through the open slot is aproximately 0.9% of the air flowing through the gate. Note that this leakage is only present when the gate is open.
