The Sporlan Catch-All or SF-283-F Suction Filter has been used for

many years as an oil lter in refrigeration rack systems with mineral

or alkylbenzene oil.

With the use of the new polyolester (POE) oils, system chemistry

changed. 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 retrot.

Analysis of POE oil samples taken from actual systems have shown

the oil to suspend and recirculate a high concentration of 2-20 micron

sized particles, with the largest percentage between 2-10 microns. Al-

though some particles are smaller than bearing tolerances, studies

have shown bearing life can still be affected. Bearing wear depends

upon the size, hardness, and concentration of particles in circulation.

To effectively remove these small particles, Sporlan developed a new

type of oil lter.

The OF Series Oil Filters are designed to be 99% efcient in remov-

ing 3 micron sized particles and yet have sufcient ow capacity at

a low pressure drop. The unsurpassed ltration ability of the oil l-

ters will assure clean POE, mineral or alkylbenzene oil is returned to

the compressors. Clean oil ensures proper operation of the oil level

control and minimizes compressor wear. The Sporlan OF Series Oil

Filters were designed to virtually eliminate the need for oil changes

resulting from suspended solid contaminants in circulation.
