Recirculation fans | our products
Recirculation fans
Recirculation fans are specially designed to create an aerodynamic airflow. They ensure even air distribution in the barn and have a cooling effect. Do you have questions about these fans? We are happy to help you make the right choice.
Multifan recirculation fan
Recirculation fans are specially designed to create an aerodynamic airflow. These fans are extremely efficient and provide a long throw. They are resistant to harsh climatic conditions, including high temperatures.
Thanks to their reflective white color, they are particularly suitable for use in horticultural greenhouses in series or parallel ventilation systems. They are also ideal for poultry houses, milking parlors, smaller industrial halls, or other spaces.
Eco-Prop recirculation fan
The Eco-Prop stands out thanks to its excellent energy efficiency. Thanks to its large diameter, this Stienen fan moves just as much air as smaller, conventional fans, but at a much lower speed.
This offers three important advantages:
- Significant energy savings
- Low noise level.
- Less draught and/or drying out
The Eco-Prop can be precisely controlled with the MPM-5 or SPM-6/12 power controller or via a frequency converter (inverter).
V-FloFan
The V-FloFan is specially designed for vertical ventilation. For the uniform development of animals, it is important that heat is distributed optimally throughout the barn. With the V-FloFan, you can limit the negative effects of temperature differences in the barn while also using energy efficiently.
Vertical ventilation brings warm air down, resulting in an optimal microclimate at animal level. In addition to its use in intensive livestock farming, this fan is also ideal for use in horticultural greenhouses and (other) industrial environments.
Recirculation fan basket fan
The Multifan recirculation fan in basket design is suitable for a wide range of applications thanks to its combination of air circulation and extraction. Thanks to the variable diameters and capacities, these fans can be used in various building structures and under different conditions.
Examples include:
- Distribution of fresh air to improve the working environment

- In harsh production conditions
- In humid environments
- For more aggressive vapors
Dairy/Basket Fans (incl. MFD)
The dairy/calf fan is the ideal solution for maintaining optimal climate conditions for dairy cattle throughout the year. Make your dairy fan adjustable and even more energy efficient with an MFD frequency converter.
The MFD inverter is a highly energy-efficient controller, specially developed and programmed for the dairy fan and mounted directly on the fan.
The cabling between the frequency converter and the fan is carried out in accordance with Kleventa's EMC guidelines. This means that only a 230V power supply and a 0–10 V control signal need to be connected.
The Multifan ceiling fan PV-600 ensures optimal air distribution during both hot and cold periods. The aerodynamically shaped blades deliver maximum air movement to all corners of the room and prevent cold zones. During warm periods, the fan provides a cooling wind chill effect for humans and animals through evaporation, which significantly reduces heat stress and supports high production in poultry, pigs, and dairy cattle.
During colder periods, the fan supports the heating system by moving the warm air that accumulates at the top of the building back into the living area. In addition to use in intensive livestock farming, this fan can also be used in factories, halls, warehouses, offices, restaurants, and other locations.
