Key Product Advantages

Integrated solid-liquid separation for conventional factory air purification

After PDp particulate pre-filtration, this DDp element simultaneously intercepts pipeline dry rust, scale, submicron oil mist and condensed water droplets that single dust filters cannot fully remove. Aggregated liquid drains fully to filter bowl, supplying stable medium-cleanliness compressed air for general processing production lines.

Optimized pleated media to reduce airflow resistance & cut energy consumption

Large-area deep-pleated gradient glass fiber forms smooth internal airflow channels, maintains stable low pressure drop under 24/7 full-load continuous operation, effectively lowering long-term power consumption of air compressors.

Large liquid & dust holding capacity extends maintenance intervals

Thick hydrophobic glass fiber matrix stores massive condensed oil, water and solid contaminants, resisting rapid saturation under medium-humidity and medium-dust workshop environments, reducing frequent replacement costs.

Oil & hydrolysis resistant reinforced construction avoids secondary pipeline pollution

Hydrolysis-proof, oil-repellent glass fiber matched with stainless steel support mesh prevents fiber shedding, eliminating contamination to downstream pneumatic valves, instruments and production equipment.

Working Principle

Pre-cleaned compressed air from PDp particulate filter flows outside-in through multi-layer hydrophobic borosilicate glass fiber media. Coarse solid particles above 1μm are trapped and stored in fiber layers; micro oil and water aerosols collide and agglomerate into large liquid droplets, then flow down fiber surface to the filter bottom drain port by gravity. Dry low-oil compressed air is delivered to subsequent activated carbon filter for terminal purification.
