Air outlet



Powerful and efficient air outlet from SKOV

In a ventilation system from SKOV, air is exhausted from the livestock house through chimneys or wall fans. We provide the most robust and efficient ventilation systems in the market, and we will be happy to create a solution to fit your needs exactly. ​

Exhaust unit
Powerful and energy-efficient solution

SKOV's aerodynamic exhaust unit combines a robust chimney with an efficient, powerful, energy-efficient fan. The air outlet unit design ensures maximum air output with low energy consumption. It is also very robust and long-lasting, whatever the climatic conditions. The unit is suitable for almost all types of livestock houses and can be installed on the roof or the side of the house. The chimney is available in several colour options and can be supplied with accessories, e.g. drip trays.

High performance, low energy consumption

The energy-efficient fan in the air outlet unit features high-pressure stability, making it less sensitive to wind, a major advantage at minimum ventilation where strong wind action could influence the air volume. The fan emits limited noise and has been especially developed for the chimney, giving you a powerful, low-energy fan.​

Wall fans
The best high-capacity fans on the market

Wall fans are ideal as additional capacity for large houses, or where large air volumes are required. When the air requirement exceeds a certain level, one or more of the wall fans can be activated to supplement the chimneys. Alternatively, all air can be let out via wall fans. Wall fans are often installed in Combi-Tunnel and Tunnel-ventilated houses in tropical/subtropical regions.

BlueFan - the next generation of wall fans

BlueFan combines a high airflow ratio with high energy efficiency. This makes it the most powerful fan on the market. It excels in the unique airtight motorized shutter system, among other things, and the fact that it is very silent when in operation.

BF 50 - high performance and energy-efficient

The BF 50 wall fan is ideal for side-mode and tunnel-mode ventilation in Tunnel and Combi-Tunnel houses. You can also combine the BF 50 with other fans of the BlueFan family to keep the animal welfare and investment in focus.






Dynamic MultiStep
Optimum climate and low energy consumption

Modern agriculture has a strong focus on lowering energy consumption, and ventilation in particular is an area ripe for significant improvement. For the past many years, SKOV has worked on developing solutions for optimal conditions for animals in livestock houses that are also energy saving.

More fans and less power consumption

SKOV has developed the control principle Dynamic MultiStep, using much less electricity to exhaust air from livestock houses. Dynamic MultiStep starts fans up at 50% of their maximum performance, and only where additional ventilation is required will the fans be stepped up in parallel to as much as 100% performance. The advantage of coupling several fans is that they all run at reduced output, thus using less power.

6 kWh per pen place per annum

Tests in a Danish slaughter pig setting indicated that energy consumption could be reduced to just 6 - 10 kWh per pen place per annum. Reduced energy consumption and the same, pleasant climate conditions for the animals - only difference noticed was a reduced noise level, a bonus for both staff and livestock.
