The negative pressure suction filter cleans liquids such as coolant or process water without the use of filter aids, by extraction. It can be used in all kinds of areas such as grinding, turning, drilling, milling, lapping as well in graphite machining.

The flat-bed filter is used for fully automatic, continuous cleaning of cooling lubricants and process water. It is characterised above all by a high level of purity. It is easy to maintain and has a long service life, making it one of the most cost-effective solutions combined with very low investment costs.

The inclined bed filter is used for fully automatic, continuous cleaning of cooling lubricants and process water. Its compact design means that a high level of cleanliness can be achieved even in conditions where space is at a premium. The filter system is suitable above all for metal processing, especially with graphite and aluminium, and can also be used in the chemicals industry, the foodstuffs sector as well as washing plants. Its simple maintenance and long service life as well as 100% exploitation of the filter material make it one of the most cost-effective filter solutions. Further advantages of this filter system are the pre-drying of the filter cake and simple separation of the waste product from the nonwoven material by means of a scraper.

The new compact filter is designed for the filtration of oil, water, emulsion and solutions with a minimum requirement of space. Working on the same principle such as paper belt filters, it can filter between 30 and 1500 l/m – according to the customer-specific design.

The magnetic filter is used for fully automatic, continuous cleaning of liquid media to remove ferromagnetic substances. The magnetic filter consists of a stainless steel housing with an electrically driven magnetic roll that is jacketed by a thin-walled stainless steel sleeve. Optionally, it can be equipped with high-performance neodymium magnets, and its modular construction means it can be individually adapted to the available space.
