Abstract

Control of the filter unit is effected via the pressure difference between the inflow and outflow sides of the filter on operation. The switching process between the filters is carried out by a device is pre-controlled by a unit functioning in relation to the filter difference-pressure. A time-control unit is connected parallel with the pre-control unit, and regulates the flush-back period of the soiled filter.
