Blast Gates for Spiral Ducting Systems

Standard blast gates made from cast aluminum to manually stop air flow within spiral ducting systems. They are available in full or half circle designs with diameters ranging from 3" - 12".  Larger diameters are available upon request. 

We recommend using other blast gates, such as the QF Manual Blast Gate NFMES, QF SD Automatic Blast Gate or EcoBOSS Automatic Blast Gate, because they are better quality and utilize cutting edge technology. However if you have a spiral ducting system and want a very simple blast gate, this product will work well.
