Jump to:
+44 (0)1296 652800 Website

Application

Ventilation louvres suitable for applications with permanent mechanical extract ventilation, in areas where:

  • High free area / high airflow solution is required;
  • Economy is primary consideration;
  • In exhaust areas where low pressure drop is needed, such as data centres.

Description

Modular ventilation louvres with excellent airflow performance, suitable for applications with permanent mechanical extract ventilation such as data centres.

Features and benefits:

  • Wide blade pitch maximizes airflow performance.
  • Channels in blades and vertical sections help to collect and drain away rain water. Louvres are classified as rain defence Class C at 0.0 m/s.
  • Visible mullions, to align with other facade elements; invisible vertical joint detail can be achieved with hidden mullions, for continuous blade appearance.
  • Delivered to site as pre-fabricated modules, for efficient installation.

Tested in accordance with EN 13030 for Rain Defence and Airflow Performance.
