Rotary Airlocks

Industrial Rotary Air Locks

Rotary air locks create a system that continuously dumps waste from the dust collector hopper to the conveyor system or collection container. The motorized valve deposits waste automatically while maintaining the air suction of the dust collector. This means less downtime, reduced dust exposure to workers, and less material and particulate running back into the system. Rotary air locks make dust collection more efficient, while keeping workers safer, and equipment protected.
