Key Product Advantages

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

After P-grade particulate pre-filtration, this Grade07 element traps ultra-fine oil aerosol that ordinary Grade10 coalescing filters cannot fully remove. The outer blue hydrophobic foam prevents secondary liquid re-entrainment, aggregated liquid droplets drain rapidly to filter bowl, supplying ultra-low residual oil compressed air for strict cleanliness production processes.

Optimized deep-pleated media balances high efficiency & low airflow resistance

Gradient folded glass 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

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 glass 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.
