Filter apparatus for filtering contaminants from a fluid, such as machine tool coolant, are disclosed. One filter apparatus includes a filter drum unit having a generally cylindrical open perforated support sheet with a cylindrical screen element mounted thereabout. Circumference varying mechanisms, such as turnbuckles, are connected relative to the support plate to vary the circumference of the support plate and the tautness of the screen element. A disc filter assembly having a mandrel and fluidly attached annular disc filter elements is also described. Each annular disc filter element has an inner structure with concentric ribs forming concentric grooves therebetween which are connected to radially extending grooves. A screen element is supported by the ribs so that the microscreen will not tear while allowing filtering of fluid into the grooves which are in fluid communication with the mandrel. A disc filter assembly having a mandrel in fluid communication with a plurality of rectangular disc filter elements is also described. Each disc filter element has a rectangular inner structure which is pleated or folded in an accordion-like fashion. A retainer secures screen elements about the inner structure to prevent contaminants from passing therebetween.

Disc filter assembly for machine tool coolant

Immersible filter drum unit and method for assembling thereof

A filter apparatus for filtering machine tool coolant is disclosed as including a drum filter or a disc filter assembly including a hollow rotatable mandrel mounting a drum filter assembly or plurality of removable hollow disc filter elements each element having a foraminous non-reticulated metal screen having minute openings and a smooth planar surface for providing improved scrape cleanability and preventing movement of machining chips, particulate and also elongate contaminants from one side of the filter to the other side thereof.

Filter apparatus for machine tool coolant

A filter apparatus (10) for filtering machine tool coolant is disclosed as including a filter assembly (12) including a foraminous non-reticulated metal screen (30) having minute openings and a smooth planar surface for providing improved scrape cleanability and preventing movement of machining chips, particulate and also elongate contaminants from one side of the filter (12) to the other side thereof.
