Farm building fan ZLV Vario

for livestock buildingsfor air circulationceiling

The ZLV Vario can be controlled centrally, i.e. multiple fresh air distributors via one actuator, or on a decentralised basis. With decentralised control every ZLV Vario can be controlled via its own motor, which is installed in the pipe. Vario fresh air distributor automatically switches to winter, transition and summer mode by means of fan module movement. The ZLV Vario’s sliding fan module makes it possible to variably adjust the recirculation gap. This makes 100% of fan output available as fresh air capacity during summer operation. Thus, the number of fresh air ducts required can be halved in comparison to standard recirculation systems. The Vario fresh air distributor delivers fresh air over the roof, with each fresh air distributor activated by a motor.
