Pyroplex® Intumescent Air Transfer Grille

Quick Overview

We offer a comprehensive range of Fire Rated Air Transfer Grille Systems that are suitable for use in fire resisting doorsets and compartment walls for up to 60 minutes fire resistance.

In normal use, the Pyroplex® system allows air to be circulated and moved throughout the building. During a fire the system is designed to close and provide a fire barrier to restrict the passage of hot gases.

Pyroplex® Fire Rated Air Transfer Grille Systems are tested for 30 and 60 minutes fire resistance.

  • Grilles are of a modular robust construction.
  • The frames are constructed from Zintec Mild Steel [0.65mm thick] with matching Zintec clips.
  • The system is easy to install and is maintenance free.
  • Pyroplex® intumescent material is totally unaffected by water, robust, ‘non-flaking’ and difficult to tear.
