JET Filter

JET Filter

The fully automatic backwash filter type JET eliminate undesirable solid particles from cooling and service water supply systems and from other hydrostatic pressure systems. The impurities are separated from the liquid by retention in special slotted tube cartridges with axial slots (100% surface filtration).

The JET Filter Type 2000 can be installed in the pipeline in any fitting position (horizontal or vertical). The filter has no moving parts.

Filterautomat DDF

Filterautomat DDF

The fully automatic operated Filterautomat DDF eliminates solids contamination in pressurised cooling and process water systems by arresting contaminants across the whole surface of a specially constructed slotted strainer element in the filter drum where these retained contaminants then become part of the filtering function (100 % surface filtration).

The Filterautomat is distinguished by an extremely robust design and an excellent backflushing performance.

Backwash Drum Filter S

Backwash Drum Filter S

The automatic Backwash Drum Filter S is distinguished by an excellent backwash performance and a compact design. An individual choice of materials for more demanding mediums can be realized.

Cleaning of the strainer with discharge of the contaminations is effected by backwashing opposite to the filtration direction from outside to inside against atmospheric pressure. The backwashing cleans the strainer without interrupting the filter process.
