• No regular control test according to ÖNORM H 6027
• Pipe connection pieces for further air ducts
• Low pressure loss
• Simple installation and retrofitting

The PRODEC-R ceiling penetration seal for inset installation is used to seal off air ducts made of spiral ducts.

It consists of a white powder-coated sheet steel housing with a pipe connection piece. Inside the housing are the intumescent and the powder-coated damper blades, which are held in the open position by a thermal release device.

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.
