Oil Separators Filters

Core Technical Specifications

Absolute Separation Precision: 0.1 μm fine oil aerosols

Oil Mist Separation Efficiency: ≥99.9999% for oil particles ≥0.1 μm

Operating Pressure Range: 0.4 ~ 1.6 MPa

Clean indoor workshop, stable continuous load: 4,000–6,000 operating hours or 12 months

Dusty workshop, frequent start-stop, heavy intermittent load: 3,000 hours maximum

Mandatory Replacement Trigger

Differential pressure across separator ≥ 0.08 MPa or obvious excessive oil consumption, oily fog & liquid oil droplets flowing out of compressed air terminal pipelines

Differential Pressure Thresholds

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

Blockage alarm differential pressure: ≥0.08 MPa

Key Product Advantages

Independent central vertical oil return tube design

Coalesced liquid lubricant rapidly drains back to the compressor oil sump via dedicated central tube, effectively reducing machine oil consumption and cutting frequent oil refilling costs.

Robust perforated steel outer support shell prevents media collapse

Galvanized perforated metal protective cage avoids fiber media deformation under long-term high airflow negative pressure, maintaining stable separation performance throughout full service cycle.

High-temperature composite fiber flange seal

Heat-resistant fiber composite gasket fully bonded to the flange surface, eliminates flange oil leakage under high operating temperature and pressure, lowering routine maintenance frequency.

Working Principle

High-temperature oil-air mixed gas discharged from screw rotors enters the separator cartridge from outside to inside.

Large liquid oil droplets sink to the tank bottom via gravity for primary gravity separation.

Fine 0.1 μm oil aerosols collide with multi-layer gradient glass fiber media, coalesce into large liquid oil droplets and flow down along the media surface to the central oil return tube.

Clean compressed air free of oil mist flows out from the separator top to post-treatment dryers and pipeline precision filters; recovered lubricant flows back to the compressor oil sump for recycling.

Separator media cannot be cleaned, washed or regenerated; full cartridge replacement is mandatory once saturated by carbon sludge and oil contaminants.

Application Scope

Automotive component manufacturing workshops, general machinery processing, plastic injection molding lines, textile pneumatic equipment, food packaging air supply, construction engineering mobile air stations, pharmaceutical factory compressed air systems.
