Operating Working Conditions

Max Working Pressure: 17 bar

Operating Medium Temperature: -10°C ~ +120°C

Applicable Medium: Mixed fluid of compressed air & compressor lubricant oil mist

Standard Service Life: 3,500–6,000 running hours (clean indoor workshop); Max 3,000 hours for dusty, heavy-load workshops

Sealing Material: FKM fluororubber flange gasket, high temperature & oil resistant, no leakage

Structural Design Features

Double-layer galvanized perforated metal support mesh (inner & outer), prevents filter media collapse under long-term high airflow pressure

Central vertical oil return tube: Condensed lubricant flows back to the compressor oil sump automatically

Integrated metal flange end cap, matching the original tank mounting holes for direct replacement

Dual-stage separation design: Gravity sedimentation for large oil droplets + coalescence separation for fine oil mist

Working Principle

High-temperature oil-air mixture discharged from the compressor airend flows into the separation tank; large liquid oil droplets sink to the tank bottom via gravity for primary separation.

Aggregated oil flows down the inner wall of the filter element and drains back to the lubrication system through the central oil return pipe for cyclic reuse.

Clean compressed air without oil mist passes through the central channel of the separator core and is delivered to downstream dryers, filters and pneumatic equipment.

Common Failures Caused by Damaged Separator Element

Excessive oil carryover in compressed air, contaminating downstream precision filters, refrigerated dryers and painting equipment, leading to mass defective products.

Sharp rise in compressor lubricant consumption, increasing regular oil refilling costs.

High differential pressure from clogged media increases motor power consumption by 10%–18%, raising electricity expenditure.

Broken filter media allows large oil droplets to enter post-processing equipment, causing permanent damage to downstream air treatment consumables.
