Pressure-relief dampers

+10

Pressure-relief dampers, also called overpressure dampers, with purely mechanical trigger system. The blades are closed in home position. When pressure rises above the specified value, the blades open and return automatically to their home position when pressure drops again.

Designed for actuation pressures from 10 up to 400 Pascal. The blades are closed in normal position. If the pressure rises above the pre-set actuation pressure, the blades begin to open. When the pressure drops below said point the blades close again.
