Airlite is a high performance natural louvred ventilator. It is dual purpose, giving highly efficient natural ventilation as well as smoke control ventilation. It is suited either for extraction or as an inlet, as well as the entry of natural daylight for most kinds of industrial and commercial buildings. It can be fitted into most types of walls and roofs. Double weather seals ensure that air leakage and heat losses are greatly reduced when it is closed. It is tested to and in compliance with EN 12101-2 and is CE marked. It is made from tough, corrosion resistant aluminium alloy and is manufactured under the ISO 9001 quality and ISO 14001 environmental management standards.

Features:

  • Certified performance.
  • Durable.
  • Energy efficient.
  • High aerodynamic and acoustic performance.
  • Wide range of applications.
