Pressure Relief Dampers

This device is used to control pressure level in adjacent zones/ areas.
Two types of Pressure Relief Dampers are available:
1) Motorized: a continuous control actuator adjusts damper blades so that the desired pressure will be obtained in the place.The actuator gets the signal from a deferential pressure transmitter
2) Counter weight: Desired pressure in the area will be obtained by opening the damper blades against or closing the damper blades by the “ adjusted counter weights” on the damper linkage
