The AIR FIRE TECH PRODEC ceiling penetration seal enables the fire protection sealing of air ducts made of spiral ducts and plastic pipes in various ceiling constructions such as solid ceilings and cross-laminated timber ceilings. It has also been tested for installation in combination with the unique TIROTECH® fire protection mortar and soft penetration seal systems.

The PRODEC cross-section-free ceiling penetration seal consists of a corrosion-resistant housing with an integrated intumescent layer. The multi-layer damper blade inside the housing is secured by the thermal release device. The free cross-section in this damper blade position makes it easy to clean the air duct using rotating brushes.

When exposed to temperatures between 70 °C and 75 °C, the triggering device reacts and the damper blade closes the cross-section by means of spring force. The integrated intumescent expands and prevents temperature transfer.
