Automated Bulk Waste Disposal Results in Significant Savings for Larger, Commercial Shops

Rotary Air Locks provide operators with the most economical, productive, and efficient way to handle bulk dust and debris, making them ideal for cabinetmakers, furniture manufacturers, and other commercial shops generating high volumes of waste material.

Our Air Locks use a high-efficiency helical drive, US-made 0.25HP hollow shaft gear motor to control the flow of discharge material from the dust collector via a rubber padded wheel that rotates at a preset speed. The airtight seal with the collector is maintained at all times, ensuring peak airflow performance while waste is continuously deposited into open bins, industrial hoppers, or transfer blower systems.
