Compact filter KF-E


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

  • Use as stand-alone cleaning unit to provide pre-filtration for ultra-fine filtration or combined with chip conveyors (e.g. in machining centers)
  • 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

Endless filter belt

Reduction of consumable and disposal costs

No carrying of cooling lubricant by the filter fleece

Reduction of costs for cooling lubricants


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 belt to the filter surface
  5. The fluid level decreases again
  6. A brush and back-flushing device clean the filter belt
