Key Product Advantages

Integrated solid-liquid separation for conventional industrial compressed air purification

After P-grade particulate pre-filtration, this medium coalescing element simultaneously intercepts pipeline rust, scale, dry dust, medium-fine oil mist and condensed water droplets that single-stage dust filters cannot fully remove. The outer red hydrophobic foam sleeve prevents secondary liquid re-entrainment; aggregated liquid droplets drain rapidly to the filter bowl, delivering stable medium-cleanliness compressed air for most general manufacturing and pneumatic equipment.

Large deep-pleated filter media reduces airflow resistance and cuts energy consumption

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

Large liquid and dust holding capacity extends maintenance intervals

Thick multi-gradient hydrophobic fiber matrix stores massive condensed oil, water and solid contaminants. It resists rapid saturation under medium-humidity and medium-dust workshop environments, reducing frequent replacement labor and material costs.

Hydrolysis and oil resistant reinforced construction avoids secondary pipeline contamination

Hydrolysis-proof, oil-repellent borosilicate glass fiber paired with stainless steel support mesh eliminates fiber shedding, preventing oil and dust contamination to downstream pneumatic valves, spraying tools and general electronic assembly equipment.

Working Principle

Pre-cleaned compressed air from the particulate filter flows outside-in through multi-layer hydrophobic borosilicate glass fiber media. Coarse solid particles above 1μm are trapped and stored inside fiber layers; micro oil and water aerosols collide and agglomerate into large liquid droplets. The outer red foam sleeve blocks droplets from being re-carried into airflow, and all condensed liquid flows down to the filter bowl drain port by gravity. Dry low-oil compressed air is delivered to subsequent high-efficiency coalescing or activated carbon filter for terminal purification.
