Air, oil and separator filters keep the compressor clean and efficient. Each has its own service interval and warning signs.
Intake Air Filter
Replace on schedule or when differential pressure rises; a clogged filter reduces output.
Oil Filter
Change with every oil change to keep lubrication clean and the air end protected.
Oil Separator
Replace when differential pressure is high or oil carryover rises, to protect air quality.
Keep Records
Log hours and replacements so no element runs past its safe life.
