Oil Separators Filters

Core Technical Specifications

Core Function: External spin-on air-oil mist primary separation

Absolute Separation Precision: 0.1 μm fine 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 hydrophobic & oleophobic HV borosilicate glass fiber composite, anti-thermal aging, compatible with all mineral and synthetic compressor lubricants

Standard Replacement Interval

Clean indoor workshop, stable continuous load: 3,500–5,200 operating hours or 12 months (whichever comes first)

Dusty workshop, frequent start-stop, heavy intermittent load: 2,200–3,500 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

Imported multi-layer HV glass fiber media for stable high-temperature separation

Adopts USA HV ultra-fine glass fiber composite material, maintains consistent oil removal efficiency under continuous 120°C high-temperature operation, no media softening or secondary oil re-entrainment.

Independent central vertical oil return tube design

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

Double-layer metal mesh anti-collapse protective structure

Internal & external perforated metal support mesh prevents fiber media deformation under long-term high airflow negative pressure, maintaining stable separation performance throughout full service cycle.

Working Principle

High-temperature oil-air mixed gas discharged from screw rotors flows into the separator canister from outside to inside.

Large liquid oil droplets sink via gravity for primary gravity separation inside the canister shell.

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.

Application Scope

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