Blast gates are used to control the flow of air from each tool station permanently connected to the dust collection system. Blast gates are normally closed allowing maximum suction to be delivered to the tool in use. Prior to starting the tool you should open the blast gate and verify it has suction.

We offer three style of blast gates:
4" Standard Plastic Blast Gate - Made from high strength ABS Plastic.
4" Quick Coupling Blast Gate - One coupler is flared slightly to allow for quick connection of standard 4" fittings. The opposite flange can be connected to a standard 4" dust hose.
4" Aluminum Blast Gate - Heavy duty construction makes this blast gate the choice for frequently used tools.
