Get These Benefits:

  • In-line bag filters protect to-the-spindle, through-the-spindle and through-the-tool coolant systems, preventing tool breakage & machine shutdowns
  • Cleaning cutting oil or coolant greatly extends tool life
  • Keller bag filters are easily installed in-shop in the oil or coolant lines
  • Low cost, long life filter bags are easily replaced in a couple of minutes

Removing chips and fines from coolant or cutting oil before fluid enters the distribution manifold prevents blockage in the lines and spray nozzles and ensures that the desired fluid flow rate and distribution is maintained throughout the run. In addition, running with solids-free cutting fluid will increase tool life and minimize the requirement to shut down for machine adjustments and maintain dimensional specifications.

Keller bag filter housings with felted polyester bags provide excellent solids holding capacity to ensure uninterrupted runs. Filter bags are easily changed without tools in a couple of minutes. The economical filter bags are available in ratings from 1 micron to 100 microns at the same prices. 25 micron bags are supplied as standard, or the customer may specify a different micron rating. The filter housings, available in 3/4″ and 1-1/2″ pipe sizes, are easily shop-installed downstream from the oil or coolant pump. Maximum operating pressure is 300 psig.
