Fans
Multifan produces many types of fans. In gardening, fans are mostly used for parallel and serial operation. They serve to equalize the temperature in the greenhouse by forcing air movement. Recently, also gutter fans appeared, that are increasingly more often used in combination with top fans systems.

Parallel recirculation:
For parallel recirculation of air, the fans are suspended in a greenhouse in one row, for example at the passage, towards the wall. The air travels over the crop towards the walls. This allows for quick temperature equalization and for relative humidity in the facility.
Serial recirculation:
The fans are suspended in series, one after the other, above the crop, from wall to wall. Such setting makes it possible for the air blown out of one fan to be drawn in by the next fan standing in a row. This causes air movement over the crop, providing a weak breeze. For this type of fans we can install speed controllers for smooth speed control.
