Fluid centrifuge CA 100

Flüssigkeitszentrifuge CA 100 – KNOLL Maschinenbau GmbH


The CA 100 automatic fluid centrifuge is a centrifugal separator for the continuous fine cleaning of cooling lubricants (CL) and other oils.

Ideal areas of application are

- Bath maintenance on centralized or decentralized filter systems (prevents the concentration of fine particles of steel, carbide, silicon, ceramic, graphite, etc.)
- Sludge concentration of reverse flow filters
- Full-flow cleaning of smaller fluid volumes from precision machining processes



Short regeneration cycle due to mechanical braking system

Fast and dynamic adaptation to the machining processes

Frequency-controlled, wear-free direct drive via coupling

Permanently low operating costs

Sound and oil mist isolation by means of closing flap

Low environmental impact from noise and emissions

Electronic vibration monitoring with automatic stop function

High process reliability

Separate speed monitoring of motor and drum

High process reliability

Automatic flushing of rotor and centrifugal valves

Low maintenance requirement


1. Separation

  • The drum accelerates to maximum speed.
  • After the fluid to be cleaned enters, it spreads out in a ring on the drum wall due to the centrifugal forces.
  • The dirt particles migrate outward due to their greater weight.
  • A scraper tube picks up the cleaned fluid and conveys it out of the drum.

2. Drying 

  • The fluid supply stops.
  • At reduced speed, the centrifugal valves open.
  • The residual fluid emerges from the drum.

3. Discharge

  • The brake stops and blocks the drum.
  • The scraper blades rotate in the opposite direction.
  • The semi-solid dirt falls down out of the centrifuge.

4. Flushing

  • The drum accelerates, fluid flows into the centrifuge again.
  • Then the drying and discharge phases start again.
