TECHNICAL DATA
The KL-E type pressure relief damper is a design variant with a control function which, as soon as the opening pressure is exceeded, keeps the pressure in the ductwork almost constant, irrespective of the volumetric flow range.
When the pressure in the ductwork falls back to its normal range after the malfunction has been corrected, the damper closes automatically.

The overpressure / high-pressure / high-flow damper is recommended for high opening pressures.
