Clean low-dust environment: 3,000–6,000 operating hours or 12 months

Initial pressure drop of brand-new element: ≤0.02 MPa

Alarm replacement differential pressure: ≥0.08 MPa

Structural Construction Features

Sealed heavy-duty metal outer shell, anti-corrosion, adapt to outdoor portable compressor working conditions

Built-in integrated sealing gasket, avoid external leakage after installation

Independent central oil return pipeline, returns coalesced lubricant back to oil circuit to prevent secondary oil re-entrainment

Key Product Advantages

Deep-pleated media with stable low pressure loss

Reasonable pleat area accommodates oil sludge and liquid contaminants. Differential pressure rises gently during operation, maintaining stable separation efficiency.

Integrated spin-on design, quick maintenance

No complicated flange disassembly. One person can finish replacement within 5 minutes, greatly reducing compressor downtime.

Rugged shell suitable for outdoor portable compressor

Impact-resistant metal housing, adapt to construction site, mining and mobile harsh working environments.

Built-in oil return system to control residual oil

Coalesced liquid oil flows back to lubrication circuit, prevents oil mist penetration and effectively reduces compressor oil consumption.

Working Principle

High-temperature oil-air mixed gas enters separator outer cavity. 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.

Liquid lubricant flows downward along filter media, converges into built-in oil return channel and flows back to compressor lubrication circuit.

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

Construction engineering sites, mining operations, road construction, automotive component electrostatic painting workshops, small machinery processing pneumatic stations.
