Key Product Advantages

Medium Polishing Stage for Standard Precision Manufacturing

Installed downstream of 50075R general coalescer, this M grade cartridge removes fine 0.1μm oil/water aerosols that R grade cannot intercept. The outer white hydrophobic foam prevents secondary liquid re-entrainment; coalesced oil and moisture drain rapidly to the filter bowl, delivering medium-clean compressed air for common precision pneumatic processes.

Deep-Pleated Low-DP Media for Energy Saving

Optimized deep-fold gradient glass fiber maximizes effective filtration area, maintaining stable low pressure drop under 24/7 full-load continuous operation, lowering long-term power consumption of medium & large air compressor units.

Sufficient Liquid Holding Capacity Extends Maintenance Intervals

Thick multi-gradient hydrophobic fiber matrix provides ample oil & water storage volume, resisting rapid saturation under medium-humidity workshop environments and cutting frequent replacement labor and spare parts costs.

Hydrolysis & Abrasion Resistant Fiber-Free Construction

Oleophobic borosilicate glass fiber paired with stainless steel support mesh eliminates fiber shedding under long-term humid compressed air operation, avoiding secondary pipeline contamination to downstream valves and processing equipment.

Working Principle

Pre-cleaned compressed air from 50075R coalescer flows outside-in through the filter cartridge:

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

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

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

Medium-clean dry compressed air is delivered to downstream S high-efficiency filter or general precision production equipment.

Application Industries

General precision automation production lines, small batch food packaging, low-demand pharmaceutical labs, ordinary electronic assembly workshops, medium factory centralized air compressor stations, general metal spraying workshops, textile printing equipment, packaging machinery.
