Oil Separators Filters

Core Technical Specifications

Filtration Grade: 0.1μm high-efficiency coalescing separation

Absolute Separation Precision: 0.1 μm submicron oil aerosol capture

Filter Media: Multi-layer hydrophobic & oleophobic borosilicate glass fiber composite, hydrolysis resistant, max continuous working temp 110°C

Mandatory Replacement Trigger: Differential pressure ΔP ≥ 0.08 MPa or visible oil carryover downstream

Differential Pressure Thresholds

Initial pressure drop of new element: ≤0.02 MPa

Blockage alarm differential pressure: ≥0.08 MPa

Structural Construction Features

Sealed impact-resistant metal outer shell, adapt to portable compressor outdoor construction harsh environment

One-piece integrated bottom sealing gasket, eliminate thread joint oil leakage after installation

Independent central oil return channel, recycled coalesced oil back to compressor lubrication circuit to cut oil consumption

Anti-static glass fiber media, avoid static spark risk in flammable painting & chemical workshops

Key Product Advantages

Deep folded glass fiber media with large dirt holding capacity

Store massive carbon sludge and dust, slow differential pressure rise during service life, reduce compressor energy loss.

Tool-free quick spin-on replacement

No complicated oil tank disassembly; one worker finishes swap within 4 minutes, minimize construction equipment downtime.

Heavy-duty anti-corrosion shell for mobile equipment

Anti-rust coating shell resist rain, dust and oil vapor corrosion, not easy to deform under frequent vibration of mobile compressors.

Stable low oil emission performance

Built-in independent oil return system, effectively control exhaust residual oil, protect downstream dryers and precision filters.

Working Principle

High-temperature oil-air mixed gas flows into separator outer cavity from compressor oil tank outlet; large oil droplets sink by gravity for primary separation.

Remaining 0.1μm ultra-fine oil mist penetrates multi-layer gradient glass fiber media; tiny oil particles collide and aggregate into large liquid oil droplets.

Coalesced lubricant flows down along filter media, converges into central oil return tube and flows back to compressor oil circuit for recycling.

Clean compressed air with residual oil ≤3 ppm flows out to post-processing purification equipment and pneumatic terminals.

Filter element cannot be cleaned or regenerated; once media saturated, differential pressure surges and separation efficiency fails, full replacement required.

Application Scope

Road construction engineering sites, mining mobile air stations, automotive component painting workshops, small metal cutting & welding factories, general machinery pneumatic equipment.
