Air Dryer Cartridge Assembly OE 3543080-90009 for Dongfeng GX & KX Heavy Trucks

This genuine air dryer cartridge with OE number 3543080-90009 is factory original replaceable filter core exclusively matched for Dongfeng GX and KX heavy-duty truck air dryer units, model FI23 integrated with molecular sieve desiccant and oil separation filter to purify compressor compressed air before entering brake air tanks. The thick steel canister body adopts anti-rust metal coating, built-in multi-layer composite filter media first intercepts compressor oil mist, then high-efficiency molecular sieve absorbs water vapor, outputting dry oil-free air to safeguard all brake valves and pipelines. Standard threaded mounting base with full-circle rubber sealing gasket avoids air leakage after replacement. It supports automatic regeneration cycle to restore desiccant adsorption capacity and extend service interval. This dryer cartridge strictly passes DFCV OEM moisture absorption efficiency test, oil separation filtration test and long-term pressure fatigue test. Authorized third-party brake component inspection verifies thread size, desiccant filling volume and sealing dimension fully consistent with factory original assemblies, widely used as routine maintenance replacement parts for saturated, failed dryer cartridges on Dongfeng GX & KX long-haul fleets.

PRODUCT DESCRIPTION

FI23 Integrated Oil Separator, High-Capacity Molecular Sieve, Full Seal Anti-Leak Base

This OE 3543080-90009 FI23 dryer cartridge integrates built-in fine oil separation filter and high-capacity molecular sieve desiccant in one canister. The composite filter layer efficiently traps engine compressor oil mist to stop oil contamination blocking brake valves, while high-density molecular sieve absorbs large volume of water vapor even under high humidity weather. The cylindrical shell is made of thick stamped steel with anti-corrosion electroplating finish, resisting rust from humid road environment. The bottom threaded mounting base matches Dongfeng GX & KX air dryer housing perfectly, equipped with a full-circle elastic rubber sealing ring to eliminate compressed air leakage between cartridge and dryer tank. Multi-hole uniform air inlet design ensures full contact between airflow and desiccant, maximizing drying efficiency, and the cartridge supports automatic air regeneration during vehicle parking to recover moisture absorption performance without frequent replacement.

Single Layer Desiccant Poor Oil Filtration, Thin Canister Easy Rust, Mismatch Thread Cause Air Leakage

Heavy truck brake maintenance technicians often face brake system failures caused by inferior aftermarket dryer cartridges: single-layer desiccant without oil separator allows oil mist to stick on brake valve spools and lead to valve jamming; thin uncoated steel canisters rust quickly after water intrusion, causing shell perforation and air pressure loss; non-OEM thread size mismatches create gaps between cartridge and dryer tank, generating continuous air leakage and insufficient brake air pressure. This genuine DFCV OEM FI23 dryer cartridge completely eliminates these hidden dangers: dual oil-water separation design purifies air thoroughly; anti-rust thick steel shell extends service life; 1:1 matched thread & seal prevents leakage, cutting brake system overhaul frequency and cold-season pipeline freeze faults for Dongfeng GX & KX fleets.

DFCV OEM GX/KX Brake Air Standard, Multi-Round Filtration, Absorption & Pressure Lab Testing

As a core consumable maintenance spare part of Dongfeng GX & KX heavy truck air brake air treatment system, this FI23 air dryer cartridge fully complies with Dongfeng Commercial Vehicle official brake air purification component production quality standards. Every finished dryer cartridge completes three mandatory professional durability laboratory tests: long-term oil mist separation efficiency test, high humidity moisture absorption saturation test, alternating air pressure cycle anti-leakage test, maintaining stable drying and filtration performance under coastal rainy weather, cold northern winter and high-load mountain transportation environments. Anti-counterfeit QR code label with printed OE part number is attached on original packaging carton for genuine product traceability, all bottom thread specification, canister outer diameter and sealing gasket size strictly follow original vehicle factory engineering drawings, zero assembly mismatch after replacement for all Dongfeng GX and KX heavy truck models.
