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 high-speed turbulent airflow

Key Product Advantages

It limits outlet air residual oil below 3 ppm, fully protects downstream refrigerated dryers, adsorption dryers and inline precision coalescing filters from heavy oil contamination and premature failure.

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

Multi-gradient HV glass fiber composite media provides generous oil sludge storage capacity, slowing differential pressure rise throughout full service cycle even under continuous heavy oil load. 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 high-speed turbulent airflow, sustaining stable low oil carryover performance for full service life.

Lightweight anti-corrosion aluminum flange & galvanized steel framework adapts to humid high-temperature tank environments

All metal support frames adopt 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.

Air-Oil Separation 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 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 painting workshops, metal cutting & welding factories, small plastic injection molding lines, food & beverage packaging pneumatic systems, textile factory central compressed air supply, small pharmaceutical aseptic production gas supply, general machinery machining pneumatic tool stations.
