The FA filter unit is used to filter out dirt particles from the cleaning solution and enables the service life of the ultrasonic bath to be extended from a volume of 13 litres. The cleaning system is suitable for filtering aqueous cleaning media up to a maximum liquid temperature of 70 °C.
The filter unit FA consists of two filter housings made of polypropylene (PP) and a magnetically coupled centrifugal pump, which are mounted together on a bracket made of stainless steel sheet. The pre-filter serves to protect the pump from coarse contamination. The fine filter is used for depth filtration.
Further equipment includes a pressure switch, a ball valve, a switch box with ON button, a main switch and 2 metres of connection cable with earthing contact plug.
- The pressure switch switches off the pump when the fine filter is clogged. The fine filter can then be replaced.
- The ball valve can be used to adjust the flow rate.
- The pump of the filter unit must be below the liquid level of the tub.
