Key Product Advantages

Primary core separation component to control residual oil content of compressed air

This built-in flange separator is installed at the outlet of the oil tank to capture tiny oil aerosols generated after rotor compression. It limits outlet air residual oil below 3ppm, protecting downstream refrigerated dryers, desiccant dryers and precision inline coalescing filters from heavy oil contamination.

Multi-layer gradient HV glass fiber media with long service life & stable low pressure loss

Imported US HV multi-gradient glass fiber composite media provides ultra-large oil holding capacity, slowing differential pressure rise during full service cycle. The layered coalescing structure efficiently gathers micro oil droplets into large liquid oil for gravity reflux, maintaining consistent low airflow resistance.

Integrated oil return pipeline design avoids secondary oil re-entrainment

Coalesced liquid oil flows down the central built-in drain tube directly back to the bottom oil sump, preventing separated oil from being blown back into clean air stream by high-speed airflow, maintaining stable low oil carryover output all service cycle long.

Full galvanized steel anti-corrosion framework adapts to humid industrial working conditions

All metal supporting structures adopt galvanized anti-rust treatment, resisting long-term erosion of high-temperature oil vapor and acidic condensate inside the oil tank, avoiding mesh rust debris contaminating the media and downstream pipelines.

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 mesh and drop into the oil tank via gravity for primary separation.

Fine submicron oil mist aerosols penetrate multi-layer gradient glass fiber media; tiny oil particles collide, aggregate and coalesce into large 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 oil sludge, differential pressure rises sharply; excessive pressure difference will break media and cause massive oil carryover failure.

Application Scope

Automotive component spraying workshops, metal cutting & welding plants, 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.
