Low Energy Louvre
The Patented Design (Patent GB2580119) has an increased effective free area, when compared to a conventional louvre, reducing resistance and therefore power required to drive the fan. With a lower fan speed running costs are reduced with the added benefit of lowering fan sound levels.
Example – Typical Louvre 1m W x 0.3 H = Resistance of 20Pa @1.5m/s
Eco-Airvent Low Energy Louvre 1m W x 0.3 H = Resistance of 4Pa @1.5m/s
Eco-Airvent Louvres can be manufactured in Steel or Aluminum with optional powder coating in any standard RAL Colour.
