Fumus

Fumus

The fresh air chimney for fresh air, mixed air and recirculated air

Fumus is equipped with a fan in the lower part of the chimney, which pushes the fresh air drawn in by the chimney through the fresh air distributor and into the barn. The amount of air entering the barn is regulated using a butterfly valve above the fan.

Depending on the position of the butterfly valve, anywhere between 100% fresh air (vertical position) and 100% recirculated air (horizontal position) enter the barn. Between these positions, a certain amount of fresh air is mixed with the house air, which is drawn in through the 10 cm wide opening at the chimney. This allows the barn to be supplied with fresh air, mixed air or recirculated air, depending on ventilation requirements.

For minimum ventilation (in the cold seasons or while heating is necessary), Fumus works with balanced pressure or slightly positive pressure.

Advantages

  • Provides good ventilation of the barn
  • Offers ideal conditions to dry the litter
  • Creates a constant warm breeze (from the mixed air)
  • Perfect for cold weather because the airflow always guarantees an ideal throwing range
  • Ensures constant air movement

Technical

  • Available with the following diameters: 650, 730, 820 or 920 mm
  • The fan ensures constant air movement – the CL 74 actuator controls the position of the butterfly valve and creates fresh air, mixed air or recirculated air as required (recommendation: individual control).
