Key Product Advantages

Front-line primary barrier to greatly extend service life of downstream coalescing & carbon filters

Installed as the first precision filter after water separator, PFE grade intercepts massive pipeline rust, welding dust, sand particulates and bulk free liquid oil/water droplets. It drastically reduces solid particle abrasion and liquid contamination load on 1600MFE medium, 1600HFE ultrafine and terminal 1600CFE carbon filters, cutting overall factory spare parts consumption and maintenance frequency by over 40%.

Ultra-large dust holding capacity with stable low differential pressure

Proprietary deep-pleated polyester needle felt media expands effective filtration area, stores massive solid dust without rapid pressure rise, perfectly matching 24/7 continuous heavy-dust industrial production. Outer hydrophobic foam rapidly drains free liquid to filter bowl, avoiding liquid re-entrainment back into large-bore air pipeline.

High-temperature stable polyester media with zero fiber shedding

Polyester filter media maintains stable structure under 80°C long-term operating temperature, no softening, pulverization or fiber shedding. Zero fiber debris enters industrial air piping to block heavy spray manifolds, large laser optical lenses and proportional solenoid valves.

Low permanent differential pressure energy-saving design to reduce large air compressor power consumption

Uniform gradient pleat layout delivers minimal airflow resistance over the full service cycle. Stable low backpressure reduces continuous motor loading of large screw air compressors and slashes long-term factory electricity operating costs.

Working Principle

Ultra-large-volume compressed air flows through filter cartridge from outside to inside:

Large solid dust particles and free liquid water/oil droplets are trapped by outer hydrophobic foam and drain down to the large filter bowl by gravity.

Fine solid particulates ≥5μm are fully intercepted and stored inside deep pleats of polyester needle felt media.

Outer anti-re-entrainment foam barrier prevents separated liquid oil/water from being re-carried by high-speed ultra-large-volume compressed airflow.

Collected liquid condensate is automatically discharged via heavy-duty industrial electronic zero-loss drain valve.

Particle-free primary clean air flows downstream to 1600MFE medium coalescing filter for secondary high-precision purification.
