Key Product Advantages

Deep interception of invisible submicron oil mist for high-end precision manufacturing

After P-grade particulate pre-filtration, this S-grade element captures ultra-fine oil aerosol that M general coalescing filters cannot fully intercept. The outer blue hydrophobic foam prevents secondary liquid re-entrainment; aggregated liquid droplets drain rapidly to the filter bowl, delivering ultra-low residual oil compressed air for strict cleanliness production processes such as automotive topcoat painting and semiconductor assembly.

Deep-pleated media balances ultra-high efficiency & low airflow resistance

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

Extra-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 labor & material costs for central air stations.

Hydrolysis-proof reinforced construction eliminates secondary pipeline contamination

Oil-repellent borosilicate glass fiber matched with stainless steel support mesh avoids fiber shedding, preventing oil-dust contamination to downstream precision instruments, spray guns and electronic assembly equipment.

Working Principle

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