Key Product Advantages

Deep removal of invisible submicron oil mist for high-cleanliness compressed air

After particulate pre-filtration, this DD element intercepts ultra-fine oil mist and water aerosol that cannot be blocked by dust filters. Tiny liquid droplets aggregate and drain down to the filter bowl, lowering residual oil content to meet strict industrial production air standards.

Optimized pleated media with low airflow resistance to cut compressor energy cost

Large-area gradient glass fiber forms smooth air flow channels, maintains stable low pressure drop under 24-hour full-load continuous operation, effectively reducing long-term power consumption of air compressors.

Large liquid holding capacity extends maintenance cycle

Thick hydrophobic glass fiber matrix stores massive condensed oil and water, avoids rapid saturation in high-humidity workshop environments and reduces frequent replacement costs.

Oil & hydrolysis resistant composite construction to prevent secondary pipeline contamination

Oil-repellent, hydrolysis-treated glass fiber matched with stainless steel mesh resists corrosion from compressor lubricant and condensed water, eliminating fiber shedding that pollutes downstream pneumatic valves and precision instruments.

Working Principle

Pre-cleaned compressed air from PD particulate filter flows outside-in through multi-layer hydrophobic borosilicate glass fiber media. Micro oil and water aerosols collide and agglomerate into large liquid droplets, then flow down along 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.
