Air Gates & Control Dampers
Blast Gates
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.
