Truck Air Dryer Assembly OE 3543010-CB4001 for Dongfeng Captain DFAC Light Commercial Trucks

This genuine integrated air dryer assembly with OE number 3543010-CB4001 is factory original pneumatic system core component exclusively matched for Dongfeng Captain DFAC light-duty trucks. It integrates drying tank, desiccant cartridge, pressure control valve and four-circuit protection valve as one complete unit, absorbing water vapor and oil mist inside compressed air from air compressor to deliver dry clean air for service brake, parking brake and auxiliary air equipment. The main housing adopts high-strength cast aluminum alloy with anti-corrosion sandblasting finish. Built-in high adsorption molecular sieve desiccant maintains stable drying efficiency under long-hour continuous operation. Standard mounting bracket, air inlet/outlet thread ports and wiring plug fully match original vehicle chassis layout for direct bolt-on replacement. This air dryer strictly passes DFCV OEM air tightness leakage test, alternating pressure cycle test and low-temperature freeze resistance test. Authorized third-party pneumatic component inspection verifies all pipeline flow, pressure protection and dimension parameters fully consistent with factory original assemblies, widely used as replacement spare parts for brake pipeline icing, rusted air valves and slow air pressure build-up on Dongfeng Captain light truck fleets.

PRODUCT DESCRIPTION

Metal mounting bracket long fixing slot and bolt hole dimension outline detail OEM air dryer unit

All-In-One Integrated Unit, High Adsorption Desiccant, Four-Circuit Overpressure Protection Valve

This OE 3543010-CB4001 air dryer combines drying tank and four-circuit protection valve into one compact assembly, eliminating separate valve matching work during maintenance. The built-in high-capacity molecular sieve desiccant efficiently captures water vapor and oil mist, preventing pipeline freeze in cold weather and internal valve corrosion. Integrated four-circuit protection valve independently controls multiple air loops, automatically cutting off air supply for individual circuit overpressure to guarantee basic brake safety. All air port thread specifications, mounting hole spacing and electrical sensor plug pin definition fully comply with Dongfeng Captain DFAC original chassis design standards. No pipeline cutting or bracket refitting required during replacement. Optimized internal air flow channel reduces air resistance to speed up vehicle air pressure accumulation.

Moisture Freeze Pipeline, Oil Corrode Air Valves, Discrete Valves Complicate Installation

Light truck maintenance technicians often encounter typical pneumatic system faults of inferior aftermarket air dryers: low-efficiency desiccant fails to filter moisture, causing pipeline blockage and brake failure in cold areas; incomplete oil separation corrodes air valves and leads to air leakage; split dryer and protection valve require complicated pipeline assembly. This genuine DFCV OEM integrated air dryer eliminates these hidden risks: all-in-one integrated structure simplifies installation; high-performance desiccant thoroughly purifies compressed air, lowering brake pneumatic system overhaul frequency for Dongfeng Captain light-duty fleets.

DFCV OEM Captain Pneumatic Standard, Multi-Round Low Temp & Pressure Lab Testing

As core air purification spare part of Dongfeng Captain DFAC light truck brake pneumatic system, this air dryer assembly fully complies with Dongfeng Commercial Vehicle official light commercial vehicle pneumatic component production quality standards. Every finished air dryer completes three mandatory durability laboratory tests: long-cycle alternating pressure fatigue test, minus 40℃ low temperature freeze resistance test, continuous air tightness leakage aging test, maintaining stable drying and pressure protection performance under cold northern winters, humid coastal and mountain bumpy transportation environments. Unique OEM part number casting mark and anti-counterfeit label are fixed on aluminum housing for genuine product traceability. All overall dimension, pipeline thread and mounting bracket outline strictly follow factory engineering drawings, zero assembly mismatch after replacement for all matching Dongfeng Captain light truck models.
