Key Product Advantages

Primary Protective Barrier to Protect Downstream High-Cost Precision Filters

As the first stage of mini compressed air purification system, this GP prefilter intercepts pipeline rust, oxide scale, metal chips, bulk liquid water and coarse oil droplets upfront. It drastically reduces pollution load on HE coalescing, DP fine dust and AC carbon cartridges, extending the service life of expensive downstream filter elements and cutting overall maintenance costs.

Compact Long-Body Design with Large Dust & Liquid Holding Capacity

Slender elongated media bed delivers larger dirt storage volume within narrow housings, suitable for installation space-limited equipment such as laser cutters, SMT machines and small spray booths. It resists frequent clogging under medium dust and high humidity working conditions.

Ultra-Low Flow Resistance for Energy Saving

Deep-pleated gradient glass fiber maximizes effective filtration area, maintaining stable low pressure drop under 24/7 continuous full-load operation, reducing extra power consumption of small air compressors.

Hydrolysis & Abrasion Resistant Fiber-Free Construction

Imported hydrophobic borosilicate glass fiber matched with stainless steel support mesh avoids fiber shedding under long-term humid compressed air operation, eliminating secondary pipeline contamination to pneumatic valves and precision processing equipment.

Working Principle

Raw unpurified compressed air flows outside-in through the filter cartridge:

Outer red foam layer captures bulk liquid water and large solid impurities;

All solid particles larger than 1μm are trapped and stored inside gradient glass fiber media;

Coarse oil & water aerosols coalesce into large liquid drops and drain to filter bowl by gravity;

Pre-cleaned low-contamination compressed air flows downstream to HE high efficiency coalescing filter for precision oil removal treatment.

Application Industries

Single-head laser cutting equipment, SMT electronic pick-and-place machines, small auto repair spray booths, laboratory precision instruments, textile textile looms, small packaging printing equipment, portable air compressor supporting systems, miniature precision pneumatic automation stations.
