Integrated flat steel flange + full-face heat-resistant fiber sealing cushion, 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 gradient glass fiber media with high dirt holding capacity & stable low pressure loss

Large pleated filtration area stores massive oil sludge, carbon deposits 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.

Independent central oil return pipeline prevents secondary oil carryover

Separated liquid oil flows back to tank bottom oil sump via dedicated central drain tube, effectively avoiding re-atomized oil mist being carried into precision production pipelines by high-speed turbulent airflow.

Full galvanized anti-corrosion conductive metal framework adapts to harsh tank environments

All metal support frames adopt galvanized anti-rust coating to resist humid high-temperature corrosive atmosphere inside oil tank; static conductive design eliminates static accumulation and hidden fire hazards.

Working Principle

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

Fine 0.1μm submicron oil mist penetrates 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.

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

Application Scope

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