Oil Filtration Systems has announced a new line of portable filtration equipment for hydraulic and lube oils. These filter carts can be used for new fill or kidney loop filtration. These new filter carts can remove four types of contaminants from industrial oils. Particulates are removed by pleated microglass filter elements to achieve particle counts as low as ISO 14/13/11. Water is removed via absorptive elements. Acid can be removed by Fullers Earth or Activated Alumina cartridges to neutralize acids, lowering the TAN (Total Acid Number) and helping to improve oil color. Finally, varnish can be removed by either granular absorbent media cartridges or depth media filters, depending on the oil temperature. The carts and skids have capacities ranging from 3 gallons per minute (gpm) to 15 gpm.
