Key Product Advantages

Heavy-duty pre-filtration to protect rear-stage filter elements

Thick multi-layer depth fiber traps most coarse solid pollutants in advance, greatly reduces dust load of DD coalescing filter and QD activated carbon filter, extends service life of expensive post-stage filter cartridges and lowers overall maintenance cost.

Ultra-low initial pressure drop for energy saving

Uniform deep-pleated large filtration area optimizes internal airflow channels. Pressure loss remains stable during 24/7 full-load continuous operation, effectively cutting compressor power consumption and operation expenses.

Extra-large dust holding capacity to extend maintenance intervals

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

Reinforced anti-corrosion stable construction

Acid-resistant PP support cage and fluorine rubber sealing rings adapt to long-term compressed air mixed with trace oil mist and condensed water. Avoid media deformation, fiber shedding and secondary air pollution.

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 particles above 1μm are fully trapped and stored inside the thick fiber matrix. Pre-cleaned compressed air flows into the next DD coalescing filter for oil & water removal before being delivered to precision production equipment.
