Key Product Advantages

All-round solid-liquid separation for conventional industrial air purification

After PD310+ particulate pre-filtration, this DDP grade simultaneously intercepts pipeline dry dust, submicron oil mist and condensed water droplets that cannot be fully trapped by single-stage dust filters. Aggregated liquid drains fully to filter bowl, supplying stable medium-cleanliness compressed air for general production lines.

Optimized pleated media for low airflow resistance and energy saving

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 reducing long-term power consumption of air compressors.

Large liquid & dust holding capacity extends maintenance cycles

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