Key Product Advantages

Deep interception of invisible submicron oil mist for high-standard clean compressed air

Installed downstream of E-B particulate pre-filter, this blue high-efficiency element traps invisible ultra-fine oil aerosol that general coalescing media cannot fully remove. Outer blue hydrophobic foam blocks secondary liquid re-entrainment, condensed oil & water drain rapidly to filter bowl, provides ultra-low residual oil compressed air for spraying, electronic assembly and laboratory precision equipment.

Deep-pleated media balances ultra-high filtration efficiency & low pressure loss

Gradient folded microglass fiber expands effective filtration area, forms smooth internal airflow channels, maintains stable low pressure drop under 24/7 full-load continuous operation, effectively cuts long-term power consumption of air compressor units.

Moderate liquid holding capacity extends maintenance cycles

Thick multi-gradient hydrophobic fiber matrix stores sufficient condensed oil and water, resists rapid saturation under medium-humidity workshop environments, reduces frequent replacement labor and spare parts cost for small & medium air compressor stations.

Hydrolysis & oil resistant construction avoids secondary pipeline contamination

Oleophobic borosilicate glass fiber matched with stainless steel support mesh prevents fiber shedding, eliminates oil-dust secondary pollution to downstream precision instruments, spray guns and electronic components. Silicon-free version available for automotive topcoat painting production lines.

Working Principle

Dust-free 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 anti-re-entrainment foam sleeve stops droplets from being re-carried by airflow;

Condensed liquid flows down to filter drain port by gravity;

Ultra-dry, ultra-low-oil compressed air outputs to subsequent activated carbon filter for deodorization & oil vapor removal.

Application Industries

Small automotive repair spray booths, single-unit laser cutting equipment, small pharmaceutical lab cleanrooms, food small-batch aseptic packaging, electronic small component assembly, laboratory precision analytical instruments, small factory decentralized air compressor stations, small precision pneumatic automation production lines.
