OF SERIES OIL FILTERS

DESIGN BENEFITS
The Sporlan Catch-All or SF-283-F Suction Filter has been used
for many years as an oil filter in systems using mineral or alkyl­­­­­­­­­­
benzene oil.

With the use of the new polyolester (POE) oils, system chem‑
istry has changed. POE oil has solvent-like tendencies and
can suspend and recirculate small, solid contaminants. POE
oil suspends and recirculates a high concentration of 2-20
micron sized particles, with the largest percentage between
2-10 microns. Although some particles are smaller than bearing
tolerances, studies have shown bearing life can still be affected.
Bearing wear depends upon the size, hardness, and concentra‑
tion of particles in circulation. To effectively remove these small
particles, Sporlan developed the OF Oil Filters.

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 unsurpassed filtration abil‑
ity assures clean POE, mineral, or alkylbenzene oil is returned
to the compressors. Clean oil ensures proper operation of the oil UL Listed under SA1756-SMGT/SMGT7 for the USA and Canada

Series Oil Filters were designed to virtually eliminate the need
for oil changes resulting from suspended solid contaminants in
circulation.
