Blast gates vs. air gates Blast gates are used to focus a dust collection system's vacuum pressure for maximum material extraction at the desired location. Blast gates are positioned near individual pieces of machinery and are closed by default — blocking air flow. When one blast gate is opened, all available suction is focused at that location, maximizing the [...]
