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 glass fiber media with large contaminant holding capacity & stable low pressure loss

Multi-gradient HV glass fiber composite media provides ultra-large oil sludge storage capacity, slowing differential pressure rise throughout the full service cycle. Layered coalescing structure aggregates micro oil droplets into large 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 steel anti-corrosion framework adapts to humid & high-temperature operating conditions

All metal supporting frames adopt anti-rust galvanized treatment, resisting long-term erosion of high-temperature oil vapor and acidic condensate inside the oil tank, avoiding rust debris shedding to contaminate media and downstream production piping.

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 jacket 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.
