Betec Cad Gas Tight Dampers 

Type : Gas Tight Damper

Model : For Electric Drive : GTD-GB-40-B-E

Blade : Aerofoil Type

Construction : Galvanized Steel (GI)

Construction : Stainless Steel (SS)

Gas tight dampers are designed such that they can isolate sections of a ventilation system with 

a very high level of sealing (gas tight). This can be required for safety reasons in certain operational conditions.

GTD-GB-40-B-E shut of dampers are designed so that after closure, even with failure of power 

supply to the actuator, the damper maintains the sealed closure in accordance with KTA 3601 

(Guidelines for Nuclear Plant) and A0 A60 (type approved) for Marine, Oil & Gas applications. 

The compact design and robust actuator

mechanisms of these shut-off dampers enable them to be installed in any orientation.
