Absolute Separation Precision: 0.1 μm micro oil mist aerosols

Oil Mist Capture Efficiency: ≥99.999% interception rate for all oil particles ≥0.1 μm

Max Continuous Working Pressure: 1.0 MPa

Continuous Operating Temperature Range: -10°C ~ +110°C

Compatible Lubricant: DEMAG original mineral & fully synthetic compressor coolant oil

Standard Replacement Cycle

Clean low-dust factory workshop: 4,000–6,000 operating hours or 12 months

Heavy dust, paint workshop & 24/7 full-load continuous production: Shorten service life to 3,000–4,500 hours

Alarm replacement differential pressure: ΔP ≥ 0.08 MPa

Outer thick perforated galvanized steel mesh jacket: Anti-rust, resistant to long-term erosion of high-temperature oil vapor & acidic condensate inside oil tank

Extra thickened perforated central support tube: Anti-collapse deformation under large-volume high-speed airflow surges

Integrated wide flat steel flange + matched original high-temperature fiber sealing gasket (included), zero air/oil bypass leakage

Central built-in micro oil return drain pipe: Collects coalesced liquid oil and refluxes back to tank oil sump to avoid secondary liquid re-entrainment by turbulent high-speed airflow

Key Product Advantages

Oversized deep-pleated gradient glass fiber media with ultra-large dirt holding capacity & stable low pressure loss

Extra wide deep pleated filtration area stores massive oil sludge, carbon deposits and liquid contaminants; differential pressure rises gently throughout full service cycle even under continuous heavy full-load oil flow. Layered coalescing structure aggregates micro oil droplets into continuous liquid film for gravity reflux, maintaining consistent ultra-high separation efficiency without performance decay.

Integrated central oil return pipeline eliminates secondary oil carryover risk

Coalesced liquid oil flows down dedicated central drain tube directly back to tank bottom oil sump, preventing separated oil from being blown back into clean air stream by large-volume turbulent airflow, sustaining stable low oil carryover performance for full service life.

Heavy-duty full galvanized anti-corrosion & anti-static metal framework adapts to harsh tank environments

All metal support frames adopt thick galvanized anti-rust coating, resisting long-term erosion of high-temperature oil vapor and acidic condensate inside oil tank; built-in static conductive structure eliminates hidden static accumulation fire hazard inside the separator element

Working Principle

High-temperature large-flow oil-air mixed gas discharged from screw rotors enters outer cavity of separator element. Large oil droplets collide with outer steel perforated jacket and drop into oil tank by gravity for primary coarse separation.

Fine submicron oil mist aerosols penetrate multi-layer gradient glass fiber media; tiny oil particles collide, aggregate and coalesce into continuous liquid oil films on fiber surfaces.

Coalesced liquid oil flows downward along media layers, converges into central built-in oil return tube, and refluxes back to oil sump for circulation reuse.

Clean low-oil compressed air (residual oil ≤3 ppm) passes through inner core support tube and flows out of oil tank to downstream air treatment equipment and production terminals.

When media is fully saturated with carbon sludge and oil deposits, differential pressure rises sharply; excessive pressure difference may crack glass fiber media and cause massive oil carryover failure.

Application Scope

Automotive component electrostatic painting workshops, metal cutting & welding factories, medium-large plastic injection molding production lines, food & beverage sterile packaging pneumatic systems, textile factory central compressed air supply, pharmaceutical aseptic production gas supply, general machinery processing pneumatic tool stations.
