The reliability of a truck’s air brake and pneumatic accessory systems depends on clean, dry compressed air. For SINOTRUK Howo vehicles, the BG1047080011 Water Trap Filter is a vital chassis-mounted component that safeguards the entire air supply network. This device is engineered to efficiently remove water, oil vapor, and solid contaminants from compressed air before they can reach sensitive valves and actuators. When sourcing dependable and high-quality Sinotruk howo parts, this specific filter stands out for its OEM-grade construction and reliable separation technology.
Designed to operate continuously under pressure, this unit is essential for preventing freeze-ups in winter, corrosion in air lines, and the premature failure of expensive pneumatic components. Regular maintenance of this filter is a cornerstone of fleet safety and reliability.
The BG1047080011 is a specialized filter designed for the air brake system of SINOTRUK Howo trucks. It is installed downstream from the air compressor, typically in the primary wet tank or supply line. Its primary function is to cool the hot, saturated air from the compressor and separate out liquid water, oil, and larger particulate matter. The unit operates on principles of centrifugal force, condensation, and coalescence. As air enters the filter bowl, it is forced into a cyclonic spin, throwing heavier water and oil droplets to the walls.
The construction typically features a durable metal or composite housing capable of withstanding high system pressures. A transparent or semi-transparent collection bowl allows for visual inspection of accumulated contaminants. A manual or automatic drain valve is integrated at the bottom to facilitate regular purging. The effectiveness of this component is critical in all climates. In cold weather, removing water prevents ice from forming in air lines and valves, which could disable the braking system.
The internal filter media of the BG1047080011 is designed to coalesce fine oil and water aerosols into larger droplets that can be easily separated and drained. This ensures extremely dry air output, protecting sensitive downstream components from moisture-related damage.
A clear collection bowl on the BG1047080011 allows for quick visual confirmation of contaminant levels without disassembly. The integrated manual drain valve enables routine purging of accumulated water and oil, which is a crucial daily maintenance task.
Manufactured from high-grade materials, the BG1047080011 housing is built to endure the constant pressure cycles, vibration, and environmental exposure typical of heavy-duty truck operation, ensuring long-term reliability and leak-free performance.

This component, specifically the BG1047080011, is not an optional accessory; it is a fundamental safety device within the truck’s air brake circuit. Moisture is the primary enemy of any pneumatic system. Water in the air lines can wash away lubricants from valves, leading to sticking or seizure. During freezing temperatures, this water can turn to ice, completely blocking small air passages in relay valves or causing brake chamber diaphragms to freeze, resulting in brake failure or unintended application.
A fully functional water trap filter, such as the BG1047080011, is the most effective defense against air system freeze-ups in cold climates. Ensuring it is drained daily and the element is replaced as needed is a critical winter safety procedure for all Howo operators.
Installation of the BG1047080011 should be performed on a depressurized system. Identify the correct location in the air line, typically after the compressor and before the primary air tank. Ensure the flow direction arrow on the filter housing aligns with the system’s air flow.
Securely mount the filter body using the provided bracket. Connect the inlet and outlet air lines using appropriate fittings, ensuring they are tightened to specification to prevent leaks. Hand-tighten the collection bowl. The BG1047080011 is designed for straightforward installation to minimize downtime.
Daily operation requires a simple but vital step: draining the collected contaminants from the BG1047080011. With the engine running and the air system pressurized, open the manual drain valve at the bottom of the bowl for a few seconds until only clean air escapes.
Periodically inspect the transparent bowl of the BG1047080011 for an abnormal amount of oil, which could indicate compressor issues. The filter element itself has a service life and should be replaced according to the vehicle’s maintenance schedule.
To replace the element or clean the bowl, depressurize the system completely. Unscrew the bowl, remove the old element, clean the bowl with soapy water, dry it thoroughly, install the new element, and reassemble. Following these steps ensures your BG1047080011 continues to function effectively.
This component, the BG1047080011, is universally critical for all Howo trucks equipped with air brakes. In regions with high humidity, the air compressor ingests more moisture, making the BG1047080011’s role even more important for daily water removal.
For trucks operating in cold climates or at high altitudes, the risk of freezing is paramount. A well-maintained BG1047080011 filter is a key component in cold-weather preparation kits to ensure brake system reliability.
In construction, mining, and dusty environments, the BG1047080011 also captures a significant amount of solid particulate. This protects the finely machined surfaces of air system components from abrasive wear.
For fleet operations, standardizing on the OEM BG1047080011 filter ensures predictable maintenance intervals and uniform protection across all vehicles. It simplifies driver training on daily drain procedures.
Genuine parts like the BG1047080011 are engineered to the precise flow and filtration efficiency specifications of the Howo air system. They ensure optimal balance between air drying and minimal flow restriction for quick brake system recovery.
Aftermarket filters may use inferior sealing materials or less effective coalescing media. This can lead to air leaks, inadequate moisture removal, or premature clogging, compromising system safety and performance.
The OEM BG1047080011 component guarantees perfect compatibility with mounting brackets and air line connections. This eliminates installation issues that could cause leaks or misalignment, ensuring the filter functions as intended.
Using the specified BG1047080011 filter supports the long-term integrity of the entire air brake system. It is a cost-effective investment that prevents far more expensive repairs to valves, tanks, and actuators down the line.
If water is found in the downstream air tanks or valves, the primary suspect is a failed or saturated filter element in the BG1047080011. The element may be damaged, incorrectly installed, or simply overdue for replacement.
If the drain valve on the BG1047080011 is stuck or leaking air, it may be clogged with debris or have a damaged seal. The valve should be cleaned or replaced to ensure the collected contaminants can be purged effectively.
A cracked or cloudy collection bowl on the BG1047080011 compromises the ability to inspect fluid levels and poses a safety risk under pressure. The bowl should be replaced immediately with a genuine part.
If the air pressure builds up slower than usual, a severely restricted filter element in the BG1047080011 could be the cause. This increases compressor workload and should be addressed by replacing the element.
The water trap filter, specifically the BG1047080011, is a small but indispensable guardian of the truck’s pneumatic systems. Its continuous operation is vital for safety, reliability, and the longevity of expensive air system components. Trust in the BG1047080011 for consistent protection.
Incorporating a daily drain ritual and adhering to scheduled element replacements for the BG1047080011 are among the most effective preventative maintenance practices an operator can perform.
Choosing the genuine BG1047080011 replacement part guarantees that this critical protection is maintained at the level originally engineered for the vehicle, ensuring compliance with safety standards.
For SINOTRUK Howo owners and fleet managers, proactive maintenance of the air filtration system with the correct components, such as the BG1047080011, is a direct contribution to vehicle uptime, safety records, and reduced total operating costs.
