Working:-

The filter unit consists of a filter base, two or four filter housings, an electric motor, a pump, an electric connection box, two sample valves and two threaded connections. There is also a pressure switch that could be used by the customer. This switch gives a signal when the pressure drop over the filter is such that a filter insert replacement is necessary. This switch does not stop the motor; it only gives information about the filter status. The oil pump is mounted on the motor. The pump is of the screw type. Two sample valves and the motor are mounted on the filter base.
The filter housings are also mounted on the filter base. Filter inserts are delivered separately and must be mounted in the filter housings before starting the filter unit. There is also a pressure gauge which measures the pressure drop over the filter. At a certain pressure drop a filter insert replacement is necessary. Each of the filter housings contains a lid with o-ring and a filter insert. The inlet connection is placed on the underside of the pump. The outlet connection is placed on the filter base.
