Spiral Manufacturing’s Air Gates are advanced, electrically controlled, compressed air-actuated blast gates designed to optimize airflow in dust collection systems. Unlike manual blast gates, Air Gates automatically activate when the connected machine is turned on, ensuring efficient dust extraction without manual intervention. Constructed with a rigid cast aluminum frame and a patented “floating” piston/cylinder assembly, they operate seamlessly across various system pressures and orientations. Compatible with duct sizes ranging from 3″ to 36″, Air Gates are ideal for applications where manual operation is impractical, enhancing both convenience and system performance.
