  • COOLANT FILTRATIONOberlin Filter

    Oberlin filters pressurize the liquid by pumping it into a chamber whose only outlet is through the unwanted solids on the media. The pressure is limited only by the size of the pump not by atmospheric pressure. 30-40 psi is typical of an Oberlin filter. This is about three to four times more pressure than gravity or vacuum filters can develop.
