1 Product description
BF 50 shutter is used in SKOV A/S positive pressure systems where the incoming air is filtrated to avoid air-
borne diseases from infecting the animals.
BF 50 shutter is without fan but with cone and shutter controlled by a stepless or ON/OFF actuator. The shutter
is controlled in relation to the amount of air passing through the livestock house while maintaining the positive
pressure in the house to prevent unfiltered air from entering though leaks.
BF 50 cone helps to prevent air entering from the outside through the shutter.
BF 50 shutter is a corrosion-free shutter.
BF 50 shutter is supplied without outside safety net - this can be ordered as an accessory.
BF 50 is specially designed for harsh livestock house environments. This applies to both climatic and electrical
influences.
