Filteranlage Kompaktfilter KF - KNOLL Maschinenbau GmbH


KNOLL compact filters KF are belt filters for cleaning cooling lubricants of machining processes

  • Use as stand-alone cleaning unit or combined with chip conveyors (e.g. in machining centres)
  • Local (for one machine tool) or central (for several machine tools) use possible



Compact design

Space-saving setup

Good price-performance ratio

Short amortization time

Greater hydrostatic pressure as compared to flat-bed filters

Higher delivery rate, lower fleece consumption and better degree of purity

Sweeping strips and scraper

Problem-free discharge of chips, even light metal ones

Can be used universally for different working processes, materials, cooling lubricants, delivery rates and degrees of purity

Simple design and planning


Filtration process

1. Contaminated liquid flows from the side through the inlet box into the            filter trough
2. The filter fleece holds back the contaminant particles during streaming
3. The contaminant particles form a filter cake, which separates even tiny           dirt particles
4. The filtered fluid collects in the clean tank

Filter belt regeneration

1. The growing filter cakes increase the flow resistance
2. The fluid level in the filter trough increases
3. The belt drive switches on at a defined level                                                        (alternatively: time-controlled)
4. The carrier belt transports a piece of clean filter fleece to the filter surface
5. The fluid level decreases again
6. A sludge container or a winding unit (option) takes up the dirty filter fleece
