Key Product Advantages

Front-stage protection for downstream filters

Capture large volume of liquid water, liquid oil and dust, extend service life of EM coalescing filter, EH high efficiency filter and EC activated carbon filter.

Simple cartridge design for fast maintenance

No complicated tools required; one person completes replacement within 3 minutes to minimize system downtime.

Wide industrial adaptability

Suitable for general machinery, packaging, laser cutting, workshop pneumatic equipment as primary purification stage.

Working Principle

Compressed air flows from outside to inside through filter media.

Large solid particles are intercepted by fiber layers. Liquid water and oil droplets collide on fiber surface, coalesce into bigger droplets and drain downwards to filter bowl.

Pre-cleaned compressed air flows out to next-stage precision filters.

The element cannot be cleaned or regenerated. Once saturated by contaminants, full replacement is required.

Application Scope

General machinery processing, laser cutting equipment, food packaging, textile machinery, small pneumatic workshops, pre-filter stage before painting air pipelines.
