Hmm. That's an interesting idea; but if a blast gate what would be the purpose of multiple doors? I have no idea, just wondering if blast gates have multiple doors. Wikipedia says: "Blast gates are used to focus a dust collection system's vacuum pressure for maximum dust (or other material) extraction at the desired location. Blast gates are positioned near individual pieces of machinery and operate by being, by default, closed — blocking air flow. When one blast gate is opened, all available suction is focused at that location, maximizing the amount of material collected".
Is this what you mean by blast gate or are you talking about a "firewall"?
