Key Product Advantages

Oversized deep-pleated gradient glass fiber media with ultra-large dirt holding capacity & stable low pressure loss

Extra tall deep pleated filtration area stores massive oil sludge, carbon deposits and liquid contaminants; differential pressure rises gently throughout full service cycle even under continuous heavy full-load oil flow. 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 massive turbulent airflow, sustaining stable low oil carryover performance for full service life.

Heavy-duty full galvanized anti-corrosion & anti-static metal framework adapts to harsh large tank environments

All metal support frames adopt thick galvanized anti-rust coating, resisting long-term erosion of high-temperature oil vapor and acidic condensate inside oversized oil tank; built-in static conductive structure eliminates hidden static accumulation fire hazard inside the separator element.

Working Principle

High-temperature ultra-large-flow 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 (residual oil ≤3 ppm) 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 large-body electrostatic painting workshops, heavy metal fiber laser cutting factories, super-large plastic injection molding production lines, bulk food & beverage sterile packaging pneumatic systems, textile mill central compressed air supply, medium-large pharmaceutical aseptic production gas supply, heavy mining machinery processing pneumatic tool stations.
