Key Product Advantages

First-stage front protective barrier to extend service life of all downstream precision filter cartridges

Installed at the very front of the four-stage purification system, this EP prefilter intercepts pipeline rust, welding debris, sand dust and massive free condensed water before they reach EM, EH and ES grade fine filters. It dramatically reduces particle and liquid load on subsequent coalescing and carbon elements, cutting overall factory spare parts and maintenance costs.

High dust & liquid holding capacity with slow pressure rise

Thickened composite fiber plus outer thick white foam dual interception design delivers massive dust storage and liquid drainage capacity. Even in humid, dusty production environments, it avoids rapid differential pressure buildup and frequent premature replacement downtime.

Stable solidified media structure with zero fiber shedding secondary contamination

Heat-set composite fiber matched with stainless steel support mesh prevents fiber powder detachment into pipelines, protecting downstream micro spray nozzles, tiny laser optical lenses and precision miniature pneumatic valves from blockage failure.

Ultra-low initial pressure drop to cut compressor energy consumption

Optimized pleat spacing and uniform pore distribution minimize startup airflow resistance. Stable low backpressure reduces continuous power loss of small screw air compressors, lowering long-term factory electricity operating expenses.

Working Principle

Raw unprocessed compressed air flows through the filter cartridge from outside to inside:

Large solid dust, rust particles and bulk water droplets are first trapped by the outer white foam layer; most free water drains down to filter bowl via gravity;

Remaining fine dust and micro water droplets are intercepted by multi-layer deep-pleated composite fiber media;

Primarily cleaned air flows downstream into 0125EM medium coalescing filter for secondary oil-water separation treatment;

Accumulated condensate inside filter bowl is automatically discharged via electronic mini auto drain valve.
