Structural Advantages

Galvanized perforated outer cage: Anti-rust, resists long-term erosion of high-temperature oil vapor and acidic condensate

Thickened central support tube: Anti-collapse under small-medium volume high-speed airflow surges

Integrated flat flange + matched heat-resistant gasket: Zero bypass leakage

Built-in central oil return pipeline: Automatically recovers coalesced lubricant back to oil sump to prevent secondary oil re-entrainment

Key Product Advantages

Deep-pleated media with sufficient dirt holding capacity & stable low pressure loss

Sufficient pleated area holds massive oil sludge, carbon deposits and liquid contaminants; differential pressure rises slowly throughout the full service cycle even under continuous full-load operation. Layered coalescing structure aggregates micro oil droplets into continuous liquid film for gravity reflux, maintaining stable ultra-high separation efficiency without performance decay.

Independent central oil return channel suppresses oil carryover

Coalesced liquid oil flows back to tank bottom via dedicated internal tube, prevents high-speed turbulent airflow from blowing separated oil back into air pipeline, keeps exhaust residual oil stably below 3 ppm and greatly reduces compressor oil consumption.

Anti-corrosion & static-safe metal frame for general industrial environments

All metal supports adopt galvanized anti-rust coating, resistant to high-temperature vapor and condensate corrosion inside oil tanks; static conductive media eliminates static discharge fire hazard in oil-air mixed atmosphere.

Working Principle

High-temperature medium-flow oil-air mixed gas from screw host enters the outer cavity of separator core; large oil droplets are intercepted and settle on outer drainage fleece via gravity for primary separation.

Remaining 0.1μm submicron oil mist penetrates multi-layer gradient glass fiber media; tiny oil particles collide, aggregate and coalesce into continuous liquid oil film.

Coalesced lubricant flows downward along media layers, converges into central built-in oil return tube and recirculates back to oil tank for reuse.

Clean compressed air with residual oil ≤3 ppm flows out from inner core air outlet to post-treatment dryers, precision filters and production pneumatic terminals.

The element cannot be cleaned or regenerated. Once media is saturated with sludge and dust, differential pressure surges and separation efficiency fails, requiring full core replacement.

Application Scope

Automotive component electrostatic painting workshops, metal cutting & welding factories, small plastic injection molding lines, food & beverage packaging pneumatic systems, textile small workshop air supply, general machinery processing pneumatic tool stations.
