Key Product Advantages

Ultra-fine coalescing for ultra-clean compressed air

Built-in pleated cellulose pre-layer intercepts coarse dust first; multi-layer hydrophobic microglass captures invisible submicron oil mist and condensed water that ordinary CU grade cannot filter out. Outlet residual oil ≤0.01ppm, meets high-standard production air requirements.

Optimized pleated structure for low energy loss

Large effective filtration area reduces airflow resistance, stable low pressure drop under 24/7 full-load continuous operation, effectively lowering long-term compressor power consumption.

Large liquid holding capacity extends maintenance cycle

Thick gradient fiber matrix stores massive condensed oil and water, not easy to saturate in high-humidity workshop environments, reducing replacement frequency.

Reinforced anti-corrosion all-metal support structure

Stainless steel mesh resists air impact, vibration and oil corrosion; epoxy-saturated glass fiber avoids fiber shedding, no secondary pipeline contamination.

Working Principle

Polluted compressed air passes through PU pre-filter to trap solid particles, then flows outside-in through multi-layer hydrophobic microglass media. Tiny oil & water aerosols collide, aggregate into large liquid droplets, flow down along the fiber surface to filter bowl drain port by gravity. The discharged air reaches Class 1 ultra-low oil purity standard for precision equipment.
