Key Product Advantages

Deep capture invisible submicron oil mist for high-standard clean air

Installed after E-B particulate pre-filter, this blue high-efficiency element traps invisible ultra-fine oil aerosol that general coalescing filters cannot remove. Outer blue hydrophobic foam stops secondary liquid re-entrainment, condensed oil & water drain quickly to filter bowl, providing ultra-low residual oil compressed air for painting, electronics, laboratory equipment.

Deep-pleated media balances high efficiency & low pressure drop

Gradient folded microglass fiber expands effective filtration area, smooth internal airflow channel, stable low pressure loss under 24h full-load operation, reduce long-term power consumption of air compressors.

Large liquid holding capacity extends maintenance interval

Thick multi-gradient hydrophobic fiber matrix stores massive condensed oil & water, not easy to saturate in high-humidity workshops, cut frequent replacement labor & spare parts cost.

Hydrolysis & oil resistant structure avoid secondary pipeline pollution

Oleophobic borosilicate glass fiber + stainless steel support mesh prevent fiber shedding, no oil-dust contamination to downstream precision instruments, spray guns, electronic components. Silicon-free version available for automotive topcoat painting lines.

Working Principle

Pre-cleaned compressed air from particulate filter flows outside-in through multi-layer hydrophobic borosilicate glass fiber media:

Tiny oil & water aerosols collide and aggregate into large liquid droplets;

Outer blue foam sleeve block droplets from being re-carried by airflow;

Condensed liquid flows down to drain port by gravity;

Ultra-dry, ultra-low-oil compressed air output to subsequent carbon filter for deodorization.

Application Industries

Automotive high-gloss electrostatic painting, multi-line laser cutting, pharmaceutical sterile cleanrooms, food aseptic packaging, electronic PCB & component assembly, laboratory precision analytical instruments, medium-large factory central air compressor stations, precision pneumatic automation lines.
