Mistraal Drum Fan Greenhouse Circulation
The Mistraal Drum Fan is a true directional airflow fan which provides maximum greenhouse air movement. Unlike regular open cage fans which tend to move the air in a “ball”-shaped flow around the fan, Mistraal Drum Fans (which are set inside a stainless steel drum) force the air down the greenhouse. Mistraal Drum Fans improve heat distribution and reduce temperature gradients. For larger areas use 8 fans per acre.
NOTE: Fans should be installed at a maximum 2.4 metres from the floor.
