800152627 XCMG GR2605 motor grader oil bath air filter

800152627 XCMG GR2605 motor grader oil bath air filter

The XCMG GR2605 grader’s 800152627 oil bath air filter is a heavy-duty core component of the engine’s intake system. Manufactured strictly according to XCMG’s original design standards and construction machinery intake filtration specifications, it is specifically designed for the Cummins QSB6.7 turbocharged intercooled engine and suitable for extreme and harsh operating environments with high dust, strong sandstorms, and high loads, such as mining operations, desert construction, and large-scale earthmoving. As an “intake protection expert” in dusty environments, it employs a triple filtration mechanism of “inertial impaction + oil adsorption + filter interception” to efficiently remove large particles of sand and fine dust from the air (≥5μm particle filtration efficiency ≥98%), providing clean intake air for the engine and preventing failures of core components such as cylinders and piston rings due to severe wear. It is a high-quality original factory accessory for the GR2605 grader’s intake system protection under extreme dust conditions, and is especially suitable for harsh scenarios where dry air filters are prone to clogging.

This oil bath air filter features a high-strength cold-rolled steel sheet shell, stamped and formed, with a double-layer anti-corrosion treatment of electrophoresis and powder coating. The shell is 3mm thick, with a tensile strength ≥345MPa, providing strong structural rigidity and withstanding severe vibrations and impacts from sand and gravel during equipment operation. It is not easily deformed or cracked. The shell’s internal spiral air intake channel guides dust-laden air tangentially into the air, generating high-speed rotation. Centrifugal inertia forces throw over 70% of large particles (≥20μm) towards the inner wall of the shell, where they fall into the bottom oil bath, completing the first stage of purification. The bottom oil bath, with a 1.2L capacity and leak-proof welding process, contains dedicated filter oil (compatible with a wide temperature range of -40℃ to 120℃). When air impacts the oil surface, it forms an oil mist that traps and adsorbs remaining dust particles, achieving a second stage of oil bath purification. A drain plug at the bottom of the oil bath facilitates regular oil changes and cleaning of deposited impurities, making maintenance convenient.

The filter housing features a multi-layered, wound metal wire mesh with an S-shaped corrugated structure, providing a filtration area of ​​0.8㎡. After being soaked in machine oil, it forms a viscous filtration barrier, providing a third layer of interception for fine dust (5-20μm) remaining after the oil bath. Simultaneously, oil mist condenses into droplets on the filter surface, flowing back to the oil sump along the mesh, forming a “filtration-recirculation” cycle to continuously maintain filtration efficiency. The filter mesh is woven from 304 stainless steel with uniform pore size (≤80μm), corrosion-resistant, and not easily clogged. It can be repeatedly washed and reused, making it more economical than disposable paper filter cartridges. The connection between the filter mesh and the housing is equipped with a nitrile rubber sealing gasket with a sealing gap ≤0.05mm, preventing unfiltered air from bypassing and ensuring thorough air purification.

The product’s air intake interface and mounting flange are precisely matched to the original XCMG GR2605 vehicle air intake system piping, with hole tolerances controlled within ±0.03mm. The flange end face is precision milled, with a flatness error ≤0.02mm, ensuring a tight connection with the air intake pipe. Equipped with original high-strength mounting bolts and anti-loosening washers, it remains secure even under 25g peak vibration conditions, without loosening or abnormal noise. A liquid level observation window is provided on the housing surface, allowing for direct viewing of the oil level in the oil sump for convenient and timely replenishment. The overall design balances filtration efficiency and air intake smoothness, with initial air intake resistance ≤3kPa, and resistance remaining ≤6kPa even with a dust capacity of 200g, without affecting the charging efficiency and power output of the engine’s turbocharger system.
