Unitex Blast Gate Dampers provide an extensive range of genuine metric sizes eliminating the problems of adapting imperial sized units to metric spiral ducting. Imperial sizes are also available.

Although principally designed for shutting off branches in dust and fume extract systems they can also be used in a wide range of other applications in existing or new systems. Unitex blast gate dampers are simple to install and easy to operate. The manually operated damper can be locked in its open or closed position by using the thumb screw.

The damper bodies are die cast aluminium alloy and the blades are of zinc plated steel. Stainless steel blades are available to special order. The dampers shown are for manual operation but pneumatically operated versions can also be supplied.
