  AIRTRAK-FR - Fire resisting ventilators
The Airtrak-FR ventilators incorporate an intumescent seal which activates in the instance of fire or at temperatures of 180-200°C. These ventilators will effectively close off ventilation apertures up to 25mm and help to control the spread of fire.


  AIRTRAK-E - ventilators for exposed and coastal locations
For increased resistance to both wind uplift in exposed locations and corrosion in coastal locations, the Airtrak ventilators can be supplied in 1.0 mm-thick, 316 grade stainless steel. Where extreme weather conditions are likely, consideration should be given to providing more weathering cover to upstands and slating or tiling to improve the integrity of the detail.
