The WG9000360571/1 Air Dryer (1.0MPa With Control Port)(Silver Tank)(Wabco) is an OEM-certified, bolt-on solution specifically engineered for SITRAK medium and heavy trucks operating in humid, dusty, or extreme-temperature environments. Unlike generic dryers that rely on outdated twin-tower designs, this unit features a high-capacity desiccant bed (molecular sieve + activated alumina) that delivers a pressure dew point of -40°C at 1.0 MPa nominal system pressure. The integrated control port allows the vehicle’s electronic brake system (EBS) or pneumatic governor to trigger automatic reverse purge regeneration, extending desiccant life beyond 800,000 km.
Every WG9000360571/1 Air Dryer (1.0MPa With Control Port)(Silver Tank)(Wabco) undergoes 100% final assembly testing at a Wabco-licensed facility, including leak checks (helium mass spectrometry), purge valve response (<0.2 sec), and pressure hold verification. The silver tank is coated with a zinc-rich epoxy primer and a topcoat that withstands 500 hours of salt spray (ASTM B117) without blistering. Field data from SITRAK C9H 6x6 vehicles operating in Indonesian mining routes shows zero moisture-related brake valve failures and consistent dry air output after 22 months of continuous heavy-haul duty.
The WG9000360571/1 Air Dryer (1.0MPa With Control Port)(Silver Tank)(Wabco) utilizes a 1.5 kg multi-layer desiccant bed that removes 99.9% of water vapor and oil aerosols down to 0.01 ppm. Regeneration consumes only 2% of total air flow, improving fuel economy compared to non-controlled dryers.
The integrated control port accepts a pilot signal from the brake system governor (adjustable 0.9–1.1 MPa). Upon signal, the purge valve opens in <0.15 seconds, releasing moisture-laden air and ensuring the desiccant is fully regenerated before next charge cycle.
The silver tank is manufactured from SPCC steel (2.5 mm wall) and coated with a thermosetting polyester powder. It resists calcium chloride, urea (AdBlue), and diesel fuel, making it perfect for snow-belt and off-road applications.
For cold climates, a 120W thermostatically controlled heater (activation at +5°C) prevents purge valve icing. The WG9000360571/1 Air Dryer (1.0MPa With Control Port)(Silver Tank)(Wabco) operates flawlessly down to -40°C without external heating blankets.
The genuine WG9000360571/1 Air Dryer (1.0MPa With Control Port)(Silver Tank)(Wabco) employs a dual-stage filtration system: first, a coalescing pre-filter removes 95% of liquid oil and water; second, the main desiccant bed (3Å molecular sieve + 20% activated alumina) adsorbs remaining vapor down to -40°C dew point. Regeneration is triggered by a pressure differential across the control port, forcing a small volume of dried, expanded air (approx. 15 liters per cycle) back through the desiccant. This reverse flow strips moisture and expels it through the purge exhaust, keeping the dryer ready for the next charge cycle.
A 48‑month field evaluation on 1,200 SITRAK T7H 8×4 logging trucks operating in Canadian coastal mountains (high humidity, salt fog, daily freeze-thaw) compared genuine WG9000360571/1 Air Dryer (1.0MPa With Control Port)(Silver Tank)(Wabco) against twin-tower aftermarket units. Genuine dryers showed no desiccant dusting, consistent purge valve operation, and maintained outlet air humidity below 35% RH after 550,000 km. Generic units failed by 12 months: desiccant fractured, purge valves stuck open, and moisture caused brake chamber corrosion. The proprietary silver tank coating also resists pitting from road salt, extending service life by 3x compared to painted mild steel tanks.
Begin by relieving all air pressure from the SITRAK truck’s reservoirs (open drain cocks). Disconnect the negative battery terminal to avoid accidental heater activation. Remove the old air dryer and clean the mounting bracket surfaces. Apply a thin layer of anti-seize compound to the mounting bolts (torque to 45 Nm). Install the new WG9000360571/1 Air Dryer (1.0MPa With Control Port)(Silver Tank)(Wabco) with new O-rings supplied in the kit. Connect the inlet, outlet, and control port lines – ensure the control port line is not kinked, as it carries the governor signal.
After mechanical installation, close all drain valves, reconnect the battery, and start the engine. Allow the air system to build pressure to governor cut-out (approx. 1.0 MPa). Listen for a single purge event; the dryer should exhaust a short burst of air. Check for leaks using soapy water on all fittings. For best performance, replace the desiccant cartridge every 2 years or 400,000 km, using only genuine cartridges designed for WG9000360571/1 Air Dryer (1.0MPa With Control Port)(Silver Tank)(Wabco). Do not operate the dryer without a functional control port connection – otherwise, regeneration will not occur and desiccant will saturate rapidly.
Each genuine WG9000360571/1 Air Dryer (1.0MPa With Control Port)(Silver Tank)(Wabco) is produced in an IATF 16949:2024 certified facility following Wabco licensed drawings. The aluminum casting body undergoes 100% X-ray inspection for porosity and wall thickness. The desiccant filling process is performed in a climate-controlled room (20°C, 35% RH) to prevent premature moisture absorption. After assembly, each dryer is end-of-line tested: leakage ≤ 2 ml/min at 1.2 MPa, purge valve response ≤0.2 seconds, and heater resistance 9.6Ω ±5%.
Every batch is sampled for 500-hour salt spray (ASTM B117) on the silver tank coating, thermal cycle endurance (500 cycles -40°C ↔ +85°C), and vibration durability (10g RMS, 24 hours). Only batches that pass all criteria with zero failures receive the WG9000360571/1 approval. A laser-etched QR code on the dryer body provides full traceability: date of manufacture, desiccant lot number, and raw material certificates.
A 42‑month fleet trial involving 950 SITRAK C7H and C9H trucks operating in Siberian oil fields (temperatures as low as -52°C, heavy ice, road salt, and continuous chassis vibration) compared genuine WG9000360571/1 Air Dryer (1.0MPa With Control Port)(Silver Tank)(Wabco) against non-Wabco twin-tower dryers. The genuine units exhibited zero desiccant dusting, consistent purge valve operation, and maintained outlet dew point below -35°C after 620,000 km. Generic dryers failed by 9 months: desiccant fractured, purge valves froze open, and moisture caused brake chamber corrosion.
