Supply ventilation shaft (CFI)
Supply air shafts (CFI) are used to bring air into the room. Depending on the ventilation scheme used, the supply shaft is equipped with various air supply and distribution systems. For systems with equal pressure in the mines, a fan with a "Corona" divider or a mixing section is installed. For negative pressure systems, the shaft is equipped with an adjustable air distributor. The supply shaft CFI (Chimney Flow Inlet) has an aerodynamic shape and is made of plastic resistant to the aggressive environment of livestock buildings. The mine is easy to clean using high pressure water jet machines. The CFI mine is equipped with a rain umbrella and ebb tide - resistant to sunlight and low temperatures. The protective net from wild birds is made of plastic, it is not subject to frost.
