Unlike mineral and alkylbenzene oils, POE oil has solvent-like tendencies. POE oil has the ability to suspend and recirculate small, solid contaminants left from system installation or retrofit. The OF Series oil filters are designed to be 99% efficient in removing 3 micron sized particles and yet have sufficient flow capacity at a low pressure drop. The Sporlan OF Series oil filters were designed to virtually eliminate the need for oil changes resulting from suspended solid contaminants in circulation. Typically, an OF Series oil filter would be installed in the oil line between the oil reservoir and the oil header of a refrigeration rack with a low pressure oil system. If the OF-303-BP is used on a low pressure oil system, it should be installed between the oil separator and oil reservoir. On a high pressure oil system, an OF Series oil filter would be installed between the oil reservoir and the oil header.
