Key Product Advantages

Deep interception of invisible ultra-fine oil mist for high-standard precision manufacturing

After NE particulate pre-filtration, this A-grade element captures invisible submicron oil aerosol that general coalescing filters cannot fully intercept. The outer white hydrophobic foam layer 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.

Deep-pleated media design balances high filtration 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 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.

Hydrolysis-proof reinforced construction eliminates secondary pipeline contamination

Working Principle

Pre-cleaned compressed air from NE 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 white 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.
