Wind driven fan Penn 200mm metal
The Penn is a wind driven roof fan. The rotating movement creates an underpressure area in the suction neck of the fan. When it is windless, the wind driven roof fan Penn functions as a good ventilation.
This fan is free of rain and is reinforced by extra brackets that fix the shaft on two sides. The wind driven roof fan achieves very fast results because it already works at wind speeds of 3m/s.
The Penn roof fan is very suitable for areas where natural ventilation does not work due to too small static pressure differences. Particularly for industrial spaces such as stairwells, factory halls, sheds, toilet buildings and the like.
This fan is only suitable for mounting on a flat roof.
