Dongfeng GX Drying cylinder assembly 3543080-TL380

As a critical component of the Dongfeng GX’s air brake system, the 3543080-TL380 assembly is responsible for removing moisture, oil, and solid impurities from compressed air—protecting downstream air brake components (e.g., valves, cylinders, sensors) from damage. The assembly uses a high-performance desiccant (typically molecular sieve or silica gel) with large adsorption capacity: it effectively absorbs water vapor from compressed air (reducing dew point to -40°C or lower), preventing condensation that could freeze in cold weather (causing brake failure) or corrode metal components. Additionally, a multi-layer filter element (e.g., polyester fiber + metal mesh) traps oil droplets (from the air compressor) and solid particles (e.g., dust, rust) with filtration precision up to 5μm. By delivering clean, dry compressed air to the brake system, the assembly ensures reliable brake operation and extends the lifespan of air brake parts by 30% or more

The 3543080-TL380 drying cylinder assembly features a robust, corrosion-resistant structure built to withstand the harsh conditions of automotive air systems and under-vehicle environments. The outer cylinder body is made of high-strength aluminum alloy (e.g., 6061-T6) with a hard anodized finish, providing excellent resistance to impact from road debris, vibration (up to 15G peak acceleration, compliant with ISO 16750-3), and corrosion from road salt or moisture. The desiccant chamber is sealed with a high-temperature-resistant rubber gasket (e.g., fluororubber FKM) that maintains airtightness even at operating temperatures up to 120°C (generated by compressed air and engine heat). The filter element uses a reinforced frame to prevent deformation under high airflow pressure (up to 1.2 MPa), ensuring consistent filtration efficiency over time. Additionally, the assembly’s end caps are secured with heavy-duty bolts, preventing disassembly due to vibration during vehicle operation

The 3543080-TL380 is engineered with Dongfeng GX-specific technical parameters to match the vehicle’s air brake system requirements. Its rated airflow capacity is optimized for the GX’s air compressor output (e.g., 200-300 L/min at 0.8 MPa), ensuring it does not restrict airflow or cause pressure drops in the brake system. The desiccant has a high moisture adsorption capacity (e.g., 20g or more per unit), allowing it to handle the moisture generated by the GX’s air compressor during long-haul operations. The assembly’s working pressure range (0.6-1.0 MPa) aligns with the Dongfeng GX’s air brake system pressure specifications, ensuring stable performance under normal and peak load conditions. It also features an automatic regeneration function (triggered by the vehicle’s air system pressure cycle): when the air compressor stops, the assembly releases dry air to purge moisture from the desiccant, restoring its adsorption capacity without manual maintenance—ideal for the Dongfeng GX’s commercial use scenarios (e.g., long-distance transportation)

The 3543080-TL380 drying cylinder assembly meets strict automotive quality standards and undergoes comprehensive testing to ensure reliability. It is manufactured in accordance with ISO/TS 16949 (automotive quality management system) and complies with Chinese national standards for air brake components (GB/T 13887-2019). Each unit undergoes 100% factory testing, including: airtightness testing (no leakage at 1.2 MPa pressure), moisture removal efficiency testing (verifying dew point reduction), filter precision testing (capturing particles ≥5μm), and durability testing (simulating 500,000+ air pressure cycles to mimic 5 years of use). The desiccant and filter element are tested for chemical compatibility with automotive lubricants and coolants, ensuring no degradation in performance. To support customers, the assembly comes with a manufacturer’s warranty (typically 12 months or 100,000 kilometers) and includes installation guidelines—making it a trusted choice for Dongfeng GX owners, fleet operators, and repair facilities seeking to maintain air brake system reliability
