Fire Testing / Structural Integrity

-Fabricated from 1st class extruded and sheet aluminium not cheaper recycled aluminium as used by the principle competitor - Colt.
- Framing is made from extruded aluminium which is typically 2.0mm thick. Colts equivalent ventilator is roll formed from 1.2mm thick sheet aluminium.
- The ventilator has been tested for structural integrity at temperatures exceeding 625°C in independent test laboratories. This exceeds the requirement of the relevant British Standard - BS7346 Pt.1.

Technical Support

-Full worldwide technical support with central back up from Zefyr Consultants in the UK.
- In house structural engineering expertise with full computational / FEA modelling facilities and physical test facilities.
- In house aerodynamic modelling facilities with 3-D computational modelling facilities for system and integration development.Ventilators and buildings can be simulated on the computer under different airflow conditions.
