Pyrogrille 100 Air Transfer Grilles
Pyrogrille – Air transfer seals
Square, rectangular and circular fire rated air transfer grilles for use in doors, walls and ducts.
Pyrogrille 100 is designed for use in fire rated doors walls and ducts, where there is a need for free air movement in normal conditions. However, when subjected to heat in a fire situation, the intumescent material swells to many times its original size and seals the aperture, forming a solid mass. Being only 38mm thick, the slim design can be used in most applications. A wide range of covers are available to enable an aesthetic view when installed.
