AXIAL FANS WITH DIRECT DRIVE FOR BUILDING VENTILATION AND AERATION
This series has the highest fan efficiency and therefore the lowest electricity consumption out of all the fans in its performance class. It is over 50% more efficient than normal round duct fans. Roughly 70% to 90% of a fan’s
total costs can be attributed to electricity costs. These costs are cut by more than 30% with GLDF fans! What’s more, the GLDF series is surprisingly affordable despite its good product properties. Its extraordinary performance data, and particularly its high fan efficiency, are due to the profiled blade shape and the continuous meridian channel. This results in very low-loss energy conversion in the fan
