Key Product Advantages

Core separation component to control residual oil content of compressed air

This internal tank separator is installed at the outlet of the oil receiver to capture micro oil aerosols generated after rotor compression. It limits outlet air residual oil below 3ppm, protecting downstream refrigerated dryers, desiccant dryers and inline precision coalescing filters from heavy oil contamination and premature failure.

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

Imported multi-gradient glass fiber composite media provides massive oil sludge storage capacity, slowing differential pressure rise throughout the full service cycle. Layered coalescing structure aggregates micro oil droplets into continuous liquid film for gravity reflux, maintaining consistent low airflow resistance without efficiency decay.

Integrated central oil return pipe eliminates secondary oil re-entrainment

Coalesced liquid oil flows down the dedicated central drain tube directly back to the 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 for the entire service life.

Full galvanized anti-corrosion & anti-static framework adapts to harsh industrial conditions

All metal supporting frames adopt galvanized anti-rust treatment, resisting long-term erosion of high-temperature oil vapor and acidic condensate inside the oil tank; built-in static conductive structure eliminates static accumulation risk inside the filter element.

Standard original flange direct replacement design for fast maintenance

Original matching multi-hole fixed flange fits factory tank mounting position perfectly. After full compressor shutdown, pressure venting and partial oil draining, maintenance staff can complete disassembly and installation within 10 minutes without pipeline modification.

Air-Oil Separation Working Principle

High-temperature oil-air mixed gas discharged from screw rotors enters the outer cavity of the separator element. Large oil droplets collide with outer steel perforated cage and drop into the oil tank via 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 the central built-in oil return tube, and refluxes back to the oil sump for circulation reuse.

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

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 fault.

Application Scope

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