WG9000360521 Air Dryer Cartridge

WG9000360521 is a high-precision air dryer assembly for SINOTRUK HOWO/SITRAK/Steyr heavy-duty trucks, compatible with WABCO matching air brake systems. As the core of the truck air brake purification system, it filters moisture, oil and impurities in compressed air, pressurizes and dries the air to a stable state, delivering clean and dry air to air storage tanks, brake valves, clutches and door pumps to ensure safe and stable operation of the brake system. Its optimized filter element and drying chamber design ensure efficient dehumidification and filtration, preventing air circuit freezing, corrosion and blockage, reducing brake system failure rate by 30%-40% and extending the service life of brake components by 50%. It resists frequent load changes in heavy transport, mining and plateau operations, maintaining stable air supply without air leakage or pressure fluctuation, and meets national automotive safety and emission standards.

①Applicable Vehicles: Fits SINOTRUK HOWO A7, T7H, T5G, SITRAK C7H, C5H, Steyr and Golden Prince. Also works for heavy trucks, engineering vehicles and special vehicles with SINOTRUK air brake systems.

②Adaptable System: Directly fit original air brake parts, including air compressor, air tank, brake valve and air pipe. No cutting, no drilling and extra adjustment needed.

③OE Reference Number: WG9000360521

④Interchangeability: Follows original installation dimensions, mounting holes and air interfaces. Direct replacement without adjusting brackets, air pipelines or fixed parts, saving maintenance time and labor costs.

⑤Value-added Service: Verifies fit via VIN, truck model and air brake system type; provides pre-installation cleaning and post-installation pressure testing guidance.

Core Materials

Dryer body uses high-strength aluminum alloy (ADC12) with good heat dissipation, corrosion resistance and light weight. Filter element adopts high-efficiency composite material (glass fiber + activated carbon) for efficient filtration of moisture and oil. Valve core and valve seat are made of GCr15 bearing steel (HRC58-62 after quenching) for wear resistance and sealing. Sealing rings are high-temperature and oil-resistant fluorine rubber, preventing air and oil leakage. Drainage valve uses engineering plastic with good impact resistance and aging resistance.

Surface Treatment

Dryer body is anodized for corrosion resistance and scratch resistance. Filter element shell is electrostatically sprayed to prevent rust. Valve core surface is polished and chrome-plated to reduce friction and improve sealing performance. Mounting surfaces are precision machined and coated with anti-seize agent to facilitate installation and disassembly. Air interfaces are chrome-plated to enhance wear resistance and air tightness.

Production Craftsmanship

Dryer body is precision die-cast with advanced molding technology, ensuring dimensional accuracy and dense structure. Filter element is made of composite material through high-temperature pressing, ensuring filtration efficiency and service life. Valve core and valve seat are paired and ground with 0.001-0.002mm clearance. Assembly with precision positioning tools ensures stable performance and low noise. Each air dryer passes air tightness test, pressure test, drying efficiency test and drainage test before delivery.

Q1: Is it compatible with SINOTRUK HOWO T7H trucks?

A1: Fully compatible. WG9000360521 is the original OE number for HOWO T7H air dryer, which can be directly replaced without modification. If you are unsure, provide the truck VIN or engine model for confirmation.

Q2: Any tips for installation?

A2: Clean all air pipes and connectors first. Use good gaskets to prevent air leak. Tighten bolts evenly, then check the drain function after fitting. Run the truck idle for a few minutes to check normal air pressure.

Q3: Can foreign trade packaging be customized?

A3: We offer neutral packing with no logo, or custom logo packing as requested. We can also change carton size and provide multi-language files for different export markets.

Q4: What if the air dryer leaks air within warranty?

A4: Just send us fault pictures, batch code and installation info. If confirmed as quality problem, we offer free replacement and cover all shipping cost.
