galvanised steelstainless steelfor pressure relief

The DRK pressure-relief damper has a convincing construction due to its purely mechanical and reliable function and use of the Lucoma modular design. The DRK is available in any combination of galvanised steel or stainless steel with aluminium or stainless steel blades. Application: The DRK is installed in duct systems or on machinery to maintain overpressure. They are mainly fitted in stairwells and smoke extraction systems. Function: Release pressure > 80 Pa The DRK is adjusted to the required release pressure at our factory to customer specifications. 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.
