Key Product Advantages

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

After primary particulate filtration, this Grade07 element removes micro oil mist that cannot be trapped by general Grade10 coalescing filters. Aggregated liquid droplets drain rapidly through the outer hydrophobic foam layer to avoid secondary re-entrainment, delivering ultra-low residual oil compressed air for precision manufacturing processes.

Large pleated filtration area for low airflow resistance & energy saving

Gradient deep-pleated glass fiber media optimizes internal airflow channels, maintains stable low pressure drop under 24-hour full-load continuous operation, effectively cutting long-term power consumption of large air compressor units.

Super large liquid holding capacity extends maintenance intervals

Thick multi-gradient hydrophobic fiber matrix stores massive condensed oil and water, resisting rapid saturation under high-humidity workshop environments and reducing frequent replacement costs.

Oil & hydrolysis resistant all-metal reinforced construction prevents pipeline secondary pollution

Hydrolysis-proof, oil-repellent glass fiber matched with stainless steel support mesh eliminates fiber shedding, avoiding contamination to downstream precision instruments, spray guns and electronic assembly equipment.

Working Principle

Pre-cleaned compressed air from particulate filter flows outside-in through multi-layer hydrophobic borosilicate glass fiber media. Tiny oil and water aerosols collide and aggregate into large liquid droplets; the outer hydrophobic foam sleeve prevents droplets from being carried back into airflow, and all condensed liquid flows down to the filter bowl drain port by gravity. Ultra-dry, low-oil compressed air is delivered to the subsequent activated carbon filter for terminal purification.
