In the compressor system, the oil itself must be filtered on a regular cycle so as to remove contaminants that may enter the compressor and damage the unit.
This is accomplished through the installation of a lube oil filter, either in cartridge, or spin-on form, which then ensures that all of the oil is cleaned as it moves through the filter.
Filtering in 5-25 micron range (depending upon application), it is again, the depositing of oil-borne contaminant over time (similar to the oil-separator), that causes the oil filter to continually increase in differential pressure to a point at which it must be replaced in order to continue proper filtration of the compressor oil.
Wanhe oil filters are built of the highest quality materials and workmanship.
Specific filtration levels are obtained through the exclusive use of high grade filter media and consistent surface area control, obtained by a strict maintenance of pleat quantity and depth. Leakages are prevented by the positive seals obtained with both plastisol and epoxy encapsulation.
Viton seals are used where applications of synthetic oil are typical.
