3" OD Self Cleaning No Clog Aluminum Blast Gate Cut Off Valve for Dust Collection System ABG3
These 3" OD blast gates are used to open and close branch ducts and direct
airflow only to those machines in operation. This conserves air volume and
keeps suction strongest where dust is being produced, thus maximizing dust
extraction. Outer case made from cast aluminum with sliding steel gate and
locking knob. Typical gate allow debris to accumulate in the groove preventing
the gate from closing fully, causing leaking and reducing suction. The slot on
these units extends through the base to allow debris to be pushed out of the
groove and prevent buildup.
