The KPK 125 odour-resistant non-return damper is equipped with a permanent magnet, which ensures the closing of the KPK 125 tight damper when pressure drops. The closing and opening pressure of the damper can be adjusted with a screw. The KPK extra tight non-return damper prevents odours and cold air from entering the ductwork. The design of the tight non-return damper allows a direct insertion into a ventilation duct. The odour-resistant non-return damper is suitable for kitchen hoods.


- prevents the penetration of undesirable odours 
- suitable for connecting of a kitchen hood to a common exhaust shaft in residential buildings
- eliminates condensation in the ductworks
- prevents the penetration of unwanted insects
- prevents the passage of smoke, e.g. from cigarettes
- reduces crosstalk noise
- quick and easy installation

Description

The KPK odour-resistant non-return damper is a magnetic, one-wing, self-closing damper used to prevent unwanted odours, cold smoke or cool air from passing through a kitchen hood into an apartment or house.

The KPK odour-resistant non-return damper is used in ventilation air extraction equipment and is designed for direct insertion into circular ventilation ducts.

The KPK airtight damper is made of ABS plastic, silicone membrane, rubber gasket, screw and magnet.

Thanks to the chosen materials, the KPK damper guarantees maximum tightness with a long-term temperature resistance of 80°C and short-term resistance up to 85°C.

The silicone used to make the damper membrane guarantees the KPK's odour-tightness for an indefinite lifetime.

The silicone membrane is made of a rubber gasket, a screw and a magnet.

Thanks to an adjustable screw in the damper body and a magnet in the plastic frame of the membrane, the KPK odour-proof damper is leak-proof and automatically closes.

There is a magnetic force between the screw and the magnet, which can be manually adjusted by tightening or loosening the screw to affect the membrane pressure.

To increase the membrane pressure, adjust the screw closer to the magnet. The reason for this step may be a higher negative pressure in the duct.

The rear of the KPK damper body is aerodynamically shaped to minimize air resistance as it passes through the damper, thus affecting the exhaust performance of the hood or centrifugal fan as little as possible.

The rubber gasket, which is located around the perimeter of the KPK damper is U-shaped, thus ensuring the strength and tightness of the damper in the duct.
