Rotary Air Locks

Rotary air locks eliminate the need for an air-tight seal with the waste container below the dust collector. Waste is automatically deposited by the motorized valve while maintaining the dust collection system's air suction performance. This significantly reduce shutdown time for emptying bins, limits dust exposure in the shop, and minimizes material back-up in the system.
