Oil Separators Filters

Core Technical Specifications

Filtration Grade: Primary submicron high-efficiency coalescing separation for medium-flow mobile industrial screw compressors

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

Filter Media: Multi-layer gradient HV borosilicate glass fiber composite media, hydrolysis resistant, continuous temperature resistance up to 108°C

Max Continuous Working Pressure: 1.0 MPa

Stable low-dust construction site: 3,000–5,000 operating hours or 12 months

Heavy dust, mining, road construction & 24/7 full-load continuous operation: Shorten service life to 2,000–3,500 hours

Mandatory Replacement Trigger: Differential pressure ΔP ≥ 0.08 MPa or obvious oil carryover in downstream air pipelines

Differential Pressure Thresholds

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

Outer perforated galvanized steel mesh jacket: Anti-rust, shock-resistant, adapts to mobile construction site vibration environment, resists long-term erosion of high-temperature oil vapor & acidic condensate

Thickened perforated central support tube: Anti-collapse deformation under airflow surges and equipment bump vibration

Integrated flat steel flange + full-face heat-resistant fiber sealing cushion, zero air/oil bypass leakage under vehicle vibration

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

Vibration-resistant heavy-duty structure for construction mobile equipment

Reinforced welding between media cage and flange, anti-loose design for frequent bumping during transportation and site operation, avoid media deformation and oil leakage failure.

Multi-layer gradient glass fiber media with large dirt holding capacity & stable low pressure loss

Large pleated filtration area stores massive construction dust, oil sludge and liquid contaminants; differential pressure rises gently throughout full service cycle even under continuous heavy oil load, 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 turbulent airflow, sustaining stable low oil carryover performance for full service life.

Working Principle

High-temperature 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, construction dust and oil deposits, differential pressure rises sharply; excessive pressure difference may crack glass fiber media and cause massive oil carryover failure.

Application Scope

Road construction, mine drilling, bridge engineering, municipal pipeline repair, quarry blasting, temporary factory pneumatic equipment supply, remote site welding & sandblasting work.
