Air Gates & Control Dampers
Air Gates (Cast Aluminum with Stainless Steel Cylinder)
A unique, electrically controlled, compressed air actuated blast gate. Mount them in even the remotest areas, and let them work for you. The operating slide design is encapsulated in a rigid cast aluminum frame and is powered by a patented “floating” piston/cylinder assembly designed for trouble free operation regardless of velocity pressures in the air handling system. Operates in any position and adapts to pipe or fittings from 3″ to 16″. Operating air pressure from 40 to 150 PSI. Factory tested and ready to install.

Control Dampers
Our series 83 Volume dampers are made of 20 gauge galvanized steel, utilizing heavy gauge plated steel quadrants, designed with excellent handle action as well as quick wing nut adjustment for locking the damper. The frame is marked to show the exact position of the damper. It uses a 3/8″ square end bearing in conjunction with a 3/8″ spring lock pin adjacent to it. Body length equals diameter plus 4″(L=D + 4). Our series 78 Double Quadrant Damper is designed for quick installation in the field and lower air pressure. This damper utilizes two fully retractable threaded spring bearings, one washer with pointer handle, and a 5/16-18 wingnut.
