WG9000360417 air dryer is a key component of the air brake system for Sinotruk heavy-duty trucks. It is installed between the air compressor and the air storage tank, used to remove water, oil vapor and impurities from compressed air generated by the air compressor. This protects brake valves, air chambers and other pneumatic components from corrosion and icing, and extends the service life of the whole air brake system. The product adopts high-efficiency desiccant and reliable pressure control structure. Each air dryer passes air tightness, pressure and dehydration performance tests before delivery. It is delivered as a complete assembly for direct replacement. We keep sufficient stock and stable bulk supply for repair workshops, fleet operators, auto spare parts dealers and global cross-border export customers.
