Frequently asked questions

Which fan should be used for a greenhouse?

Greenhouses typically use high-airflow square axial fans. 100x100 cm suits small and medium greenhouses, while 140x140 cm delivers the same air exchange with fewer units in large greenhouses. Your greenhouse's width, length and height are enough for an exact selection.

How large an area can a farm fan cover?

The area one fan covers depends on ceiling height, animal density and the required air changes per hour. The Choose Your Fan calculator on this page recommends a fan count based on your building volume.

What is the difference between 100x100 and 140x140 fans?

The 140x140 cm fan moves more air thanks to its larger blade diameter, so large volumes need fewer units. The 100x100 cm fan fits more compact openings and is offered with a 380V motor.

What is the difference between 220V and 380V fans?

220V fans connect directly to single-phase mains. 380V (three-phase) fans run more steadily and efficiently in facilities with industrial power. The 140x140 fan comes in both options; the 100x100 fan comes in 380V.

How many fans do I need?

Fans needed = volume (width × length × height) × air changes per hour ÷ fan airflow. The required air changes depend on the use case. Send us your dimensions on WhatsApp and we will size it together.

Where can the fans be used?

Greenhouses, barns, poultry houses, dairies, factories, warehouses, workshops and production plants — any large space that needs hot, humid, dusty or polluted air removed.
