GV45 gable fan with automatic flap register
This gable fan is equipped with an automatic flap register and is in practice ideally suited to bring in cool dry air from outside.
The automatic valve register prevents too cold air from entering the greenhouse during the winter period.
The valve register is controlled by the actuator, after which the fan is activated.
Thanks to the wide profile of the gable fan on the outside of the greenhouse, wind and rain impact is prevented.
The GV45 is also available with an energy-efficient EC fan, whose speed is very adjustable.
