RSK 250 TERUGSLAGKLEP VENTILATIE Ø 250 MM
SKU: e6095

Non-return damper for installation in a ventilation duct. Recommended for ventilation systems, extractor hoods, etc. Prevents outside air from re-entering the house through the duct when the fan/vapor hood is at a standstill.

Ventilation check valves are designed to ensure that, when the fan is switched off, the air in an air duct can only move in one direction. In other words, the air cannot flow back.
If there is no air movement, a spring mechanism ensures that the butterfly valve remains closed.

Diameter Ø 250 mm
