Key Product Advantages

Heavy-duty pre-filtration protects downstream filter stages

Thick multi-layer depth fiber traps most coarse solid pollutants in advance, drastically reduces dust load on coalescing and carbon filter elements, extends service life of high-cost rear-stage elements and cuts maintenance expense.

Ultra-low initial pressure drop for energy saving

Uniform deep-pleated large filtration area optimizes internal airflow passages. Stable low pressure loss under 24/7 full-load continuous operation, effectively lowering compressor power consumption and overall operation cost.

Super large dust holding capacity to prolong maintenance cycles

High-capacity gradient fiber matrix stores massive solid particulate pollutants, resists rapid clogging in dusty factory environments and lengthens filter replacement intervals.

Reinforced anti-corrosion stable construction

Acid-resistant PP support cage and fluorine rubber sealing rings adapt to long-term compressed air mixed with tiny oil mist and moisture. Prevent media deformation, fiber shedding and secondary air contamination.

Working Principle

Contaminated compressed air carrying dry dust, rust chips and coarse solid impurities flows from outside to inside through multi-layer composite fiber media. All solid particulates above 3μm are fully trapped and stored inside the thick fiber matrix. Pre-cleaned compressed air flows into the next coalescing filter for oil & water removal before being delivered to precision production equipment.
