Key Product Features

Front-stage protective performance

Blocks pipeline rust, dust, condensed water and large oil mist droplets, protects downstream PD high-efficiency filter cartridges and QD activated carbon filters to extend their service life.

Low pressure drop energy-saving design

Multi-layer gradient pleated media ensures smooth airflow, maintains low differential pressure during long-term operation and cuts power consumption of air compressors.

Hydrophobic & oleophobic surface treatment

Special coating on filter media accelerates drainage of oil and water, prevents core clogging and offers high dirt & liquid holding capacity.

Stainless steel inner support cage

Prevents filter layer collapse & deformation under high flow conditions, suitable for long-term continuous industrial operation.

Application & Industries

Serves as the first-stage pre-filter in compressed air post-processing systems, used in combination with PD and QD cartridges for staged purification.

Widely applied in general machinery, packaging, textile, general spray coating, pneumatic tools, sheet metal processing, mining equipment air source purification.
