A non woven ( paper ) fabric band is used as the filter media for the separation of the chips from the coolant oil that is made to fall over it. The filter paper is stored as a roll on the unit and is pulled out by an endless chain belt on top of which the paper rests, after use of the front portion. This filter is extensively used on grinding honing machines for filtering cast iron aluminium fine steel particles from coolant, where coolant filtration is critical. Filtration levels of 5 to 40 microns are possible. There is no cleaning of filter needed except change of filter paper roll after a long roll of paper ends. When the paper roll ends, an optional “paper end” signal can be provided to fix a new roll.
