RSK 100 TERUGSLAGKLEP VENTILATIE Ø 100 MM
Non-return valve for installation in a ventilation duct. Recommended for ventilation systems, extractor hoods, etc.
Non-return damper fitted with self-retracting blades with air seal for installation in a ventilation duct. Recommended for ventilation systems, extractor hoods, etc. Prevents outside air from 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 100 mm
