Central fan, redundancy small

Art. No. 190004

The system consists of two side channel fans and a control cabinet. The fans have been chosen with consideration to performance relating to pressure curves and noise, and are provided with pipe systems with check valves. A double set of regulator systems for the fans are mounted within the control cabinet. The system is entirely automatic (the system does not need to be started or turned off while in use).

The system functions with one system as master and the other system as slave.

The system is programmed with a low flow requirement so that only one fan is necessary; when the flow requirement exceeds the capacity, the other fan is connected.

By means of two fans and double regulation, full system redundancy is attained. If an error in the fan or in the regulation system occurs, the system automatically switches to master.

The motor regulation is connected to Medicvent’s pressure regulator. The pressure regulator is connected to the evacuation channel of the fan and directs the motor regulation by regulating the speed of the fan according to the desired flow.
