The combination of the filter chambers and the pumps created a big series most different filter units. The cover the range from 500 - 30.000 l/h. They are almost all equipped with a pressure gauge, air release valve, splash guard on the lid, a hand priming pump and an drain tap.
The most noticeable development in the youngest time are our alluvial filter units. Quality requirements showed that the filter capacity is a decisive factor. This knowledge leaded to bigger capacity as well as a better filtration quality. Nowadays an agitation of 10 times the continence of the tank per hour are no exception. In modern plating plants for high class surfaces as we know them in the PCB production and the plating on plastic this is already state of the art. The rules of protection of our envirorunent hardly allows the use of cartridges and papers any longer.
Our alluvial filter units are a systematic solution which respects these rules. In tead of bigger units we install one unit per position. In this way each cell is filtered separately. The complicated lay out of the pipes to realize a symmetrical flow and agitation of the bath are not necessary any more. For the filter we choose plastic alluvial elements. The are covered with filter aid and are cleaned with only a few gallons water without being removed. With the right filter aid it's easy possible to filter < 1 mm. But for water and filter aids there is no waste of expendable material.
Our concept provides that several filter units (10.000, 20.000 or 30.000 1/h) and a slurry tank are installed on stainless U-section. Its a tum key plant. That means, that all the pipes and valves are completely installed. Only the connections to the bath have to be made.
