Filcon Bag Filters are compact and efficient coolant filters when the accuracy desired is less than 50 Microns. The unique design of bag filter housing, basket and filter bag enables effective filtration of coolant. The contaminated liquid enters the housing above the bag and passes down through them. Contamination are retained inside the bag, from where they are easily and completely removed by replacing the bag. The outside diameter of the filter bag seals radially against the housing inside diameter and prevents entering of contamination to clean area. A simple cover with gasket is provided for opening and closing of bag filter housing. Bag filters are available from 50 LPM to 200 LPM capacities.
