Economical operation and conservation of expensive coolants used in the machine tool industry requires high quality of filtration. Correct maintenance and care of the coolant in central supply and dedicated supply systems has a direct influence on the service life of the coolant and on production costs.

To achieve optimum results, filters must:
  ensure through their precision that the fluid to be treated is cleaned to a defined degree,
  guarantee through their reliability the uninterrupted and trouble-free operating of the complete plant and
  contribute to keeping operating costs low through minimum maintenance and long service life

BOLLFILTERs can be integrated as components into all the usual plant configurations without problems like e.g.
Cold forming
CNC processing
