Core Filter Types & Functions
Air Intake Filter: The first line of defense; it traps dust and particles (above 0.3μm) to prevent internal wear on the compressor head.
Oil Filter: Removes metal shavings, carbon deposits, and debris from the lubricant to protect bearings and rotors.
Air/Oil Separator: Separates suspended oil mist from the compressed air before discharge, recycling the oil back into the system to minimize oil carryover.

Depending on the air quality requirements, additional inline filters may be installed:
Particulate Filters: Remove rust and pipe scale.
Coalescing Filters: Merge fine liquid droplets (water/oil) into larger drops for removal, filtering down to 0.01 ppm.
Activated Carbon Filters: Remove odors and organic vapors, essential for food and pharmaceutical industries.

To avoid energy loss due to pressure drops, common replacement intervals are:
Air & Oil Filters: Every 2,500 hours (shorter in dusty environments).
Oil Separator: Generally every 2,800 to 3,500 hours depending on oil quality.
