Key Product Advantages

Intermediate Coalescing Stage for Standard Industrial Air Treatment

Installed downstream of 7212620010 particulate prefilter, this green Gr10 element intercepts 1μm fine dust, bulk liquid water and coarse oil droplets that pass through the prefilter stage. It greatly reduces liquid contamination load on high-efficiency and carbon filter elements, extending the service life of downstream precision cartridges and cutting overall system maintenance costs.

Large Liquid Holding Capacity for High-Humidity Workshop Conditions

Thick multi-gradient hydrophobic fiber matrix provides abundant oil & water storage volume, resisting rapid saturation in environments with poor aftercooler and dryer performance.

Low Flow Resistance for Energy Saving

Deep-pleated glass fiber maximizes effective filtration area, maintaining stable low pressure drop under 24/7 full-load continuous operation, lowering extra power consumption of medium air compressor units.

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 pneumatic valves and general processing equipment.

Push-Fit Quick Replacement Without Housing Modification

Overall dimension and dual-gasket sealing structure perfectly match original FIAC Gr10 series filter housings; a single operator can complete cartridge swap within minutes without full housing disassembly.

Working Principle

Pre-cleaned compressed air from particulate prefilter flows outside-in through the filter cartridge:

Bulk liquid water and large solid particles are blocked by outer green hydrophobic foam;

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

Outer green 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 high-efficiency coalescing filter for further precision polishing treatment.
