Structural Construction Features

Sealed heavy-duty metal outer shell, anti-impact and anti-corrosion, suitable for indoor factory long-term continuous operation

One-piece integrated bottom sealing gasket, effectively eliminate external thread leakage after installation

Independent central built-in oil return pipeline, recover coalesced oil back to compressor lubrication circuit to prevent secondary oil re-entrainment

Full anti-static filter media, safe for painting, chemical and flammable industrial working environments

Key Product Advantages

Deep-pleated gradient glass fiber media with stable low pressure loss

Reasonable pleat area stores large volume of oil sludge and carbon deposits, differential pressure rises gently during full service cycle, reduce compressor energy consumption.

Spin-on quick replacement design, minimal downtime

No complicated tank flange disassembly; one worker completes replacement within 5 minutes without special tools, greatly shorten equipment stop time.

Rugged sealed metal housing, long service life

Anti-rust coating outer shell, resist oil vapor and condensate corrosion, not easy to deform under continuous pressure.

Built-in independent oil return system to control exhaust oil content

Coalesced liquid oil automatically flows back to lubrication circuit, effectively reduce compressor oil consumption and prevent oil pollution to downstream equipment.

Working Principle

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

Remaining 0.1 μm ultra-fine oil mist penetrates multi-layer gradient glass fiber media. Tiny oil particles collide, aggregate and coalesce into continuous liquid oil film.

Coalesced lubricant flows downward along filter media, converges into built-in central oil return channel and flows back to compressor oil circuit for recycling.

Clean compressed air with residual oil ≤3 ppm flows out to dryers, precision filters and production pneumatic terminals.

The element cannot be cleaned or regenerated. Once media is saturated with sludge and impurities, differential pressure surges and separation efficiency fails; full replacement is required.

Application Scope

Automotive component electrostatic painting workshops, metal cutting & welding factories, small plastic injection molding lines, food packaging pneumatic equipment, textile small workshop air supply, general machinery processing pneumatic stations.
