Product description

The PROVENT-A fire protection damper with mechanical closing element is used to seal off air ducts made of spiral ducts.

It consists of a white powder-coated sheet steel housing with internal and external intumescent panels. The powder-coated damper blades are held in the open position by means of a thermal release device. The U-lip seal ensures a secure hold in the air duct. The volume flow is adjusted by turning the cone.

Functionality

In the event of a fire, the thermal release device reacts between 70°C and 75°C and the damper blades close by means of spring force. The intumescent layer then expands - the pipe cross-section is closed and heat transfer to the side facing away from the fire is restricted.
