Blast Gates Maximize your Vacuum Pressure

By using our blast gates to close off lines that are not in use, you can keep the vacuum suction strongest at the point where you need it.  This will result in the maximum possible dust or debris extraction at a particular location.

Selection The Blastgate Company offers a full line of standard and custom fabricated blast gates. We also make specialty blast gates such as self-cleaning gates, positive seal (vapor-proof) gates and automatic blast gates.
Materials Construction materials are mild steel, galvanized steel, 304 and 316 stainless steel and cast aluminum.
Delivery Most Blast Gate sizes from 2" to 30" are in stock and ship the same day.
