Oil Separators Filters

Core Technical Specifications

Function: Primary tank air-oil separation

Absolute Separation Precision: 0.1 μm oil aerosols

Oil Mist Separation Efficiency: ≥99.99% for oil particles ≥0.1 μm

Operating Pressure Range: 0.4 ~ 1.6 MPa

Filter Media: Multi-layer high-temperature hydrophobic & oleophobic glass fiber composite, compatible with all KAESer mineral and synthetic compressor lubricants, resistant to thermal aging up to 120°C

Standard Replacement Interval

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

Differential pressure across separator ≥ 0.08 MPa or obvious excessive oil consumption & oil carryover at compressed air outlets

Differential Pressure Thresholds

Initial pressure drop of new separator: ≤0.02 MPa

Blockage alarm differential pressure: ≥0.08 MPa

Key Product Advantages

Specially formulated glass fiber composite maintains consistent oil removal efficiency under continuous 110°C high-temperature compressed air, no media softening or oil re-entrainment.

Central independent oil return tube design

Coalesced liquid lubricant drains rapidly back to the compressor oil sump via dedicated central tube, effectively reducing machine oil consumption and protecting downstream air treatment equipment.

Robust metal outer support shell prevents media collapse

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

High-temperature fluorine rubber flange seal

Heat-resistant FKM gasket eliminates flange oil leakage under high operating temperature and pressure, reducing maintenance frequency.

Working Principle

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

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

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

Separated clean compressed air flows out of the separator top to post-treatment filters and dryers; recovered lubricant flows back to the compressor oil sump for recycling.

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

Application Scope

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