Key Product Advantages

Deep capture of invisible ultra-fine oil mist for high-standard precision production

After AA particulate pre-filtration, this AO-grade element intercepts submicron oil aerosol that general AR coalescing filters cannot fully remove. 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 manufacturing processes.

Deep-pleated media design balances high filtration efficiency and 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 and material costs.

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. Silicon-free version meets strict coating production requirements with zero silicone pollution risk.

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.
