Filter flushing unit

The filter flushing unit can be used to fill the hydraulic units, to bleed the actuators and to flush the entire hydraulic tubing. The purity of the oil in the tram can be checked with the integrated oil purity measuring device. If necessary, the device cleans the oil to the prescribed NAS purity class stipulated in the HANNING & KAHL operating manual. The unit switches off automatically when the set values are reached. The values are stored in a memory for printing out at a later date.
