Key Product Advantages

Third-Stage Ultra-Pure Polishing Core for Large-Scale Critical Production

It drastically reduces trace liquid oil load on terminal activated carbon filter, extends carbon service life and cuts overall system maintenance and spare parts expenditure. Silicon-free variants are optional for automotive topcoat painting lines to avoid paint surface speck defects.

Extra-Large Liquid Holding Capacity for High-Humidity Heavy-Duty Factories

Thick multi-gradient pleated micro glass fiber matrix provides massive oil & water storage volume, resisting rapid saturation in large workshops with insufficient aftercooler or refrigerated dryer performance. Widely used upstream of adsorption dryers to protect molecular sieve from oil pollution.

Low Flow Resistance for Massive Energy Saving on Central Compressor Stations

Optimized deep-fold gradient micro glass fiber maximizes effective filtration area, maintaining ultra-stable low pressure drop under 24/7 full-load large-flow continuous operation, drastically cutting long-term power consumption of large centralized air compressor stations.

Hydrolysis & Abrasion Resistant Fiber-Free Construction

Oil-repellent borosilicate micro glass fiber matched with stainless steel support cage prevents fiber shedding under long-term high-flow humid compressed air impact, eliminating secondary pipeline contamination to downstream large precision production equipment.

Working Principle

Residual bulk liquid water and fine solid particles are blocked by outer red hydrophobic foam;

Trace micro oil & water aerosols collide and coalesce into large liquid droplets across multi-layer gradient borosilicate micro glass fiber media;

Outer red anti-re-entrainment foam sleeve stops coalesced liquid droplets from being re-carried by high-speed large-volume airflow;

Condensed oil and water drain down to the filter bowl by gravity and automatic drain valve;

Ultra-dry, trace-low-residual-oil compressed air is delivered downstream to activated carbon filter for complete oil vapor adsorption treatment.

Application Industries

Large automotive electrostatic painting workshops, multi-line heavy laser cutting equipment, large pharmaceutical sterile filling production lines, mass food aseptic packaging, PCB & semiconductor chip assembly plants, laboratory large precision analytical instruments, medical centralized breathing air pretreatment, heavy factory central air compressor stations, solvent mass spraying production lines, full-automatic ultra-precision large pneumatic automation production lines, front protection filter for large adsorption dryers.
