Centrifugal 1006411880 Oil Filter For Weichai Engine

The 1006411880 is a centrifugal oil filter element primarily used in heavy-duty diesel engines, such as those manufactured by Weichai Power for marine and power generation applications (e.g., Baudouin engines) .

Unlike conventional full-flow filters that rely on a replaceable paper cartridge to trap particles, this is a rotor-type filter. It operates on the principle of centrifugal force to separate and retain contaminants from the engine oil .

Key Features and Working Principle:

• Centrifugal Separation: Engine oil pressure is directed into the filter's rotor assembly, causing it to spin at high speeds (often over 5,000 rpm). The high centrifugal force, which can exceed 1,800 G's, throws heavier contaminants and sludge particles outward against the inner walls of the rotor bowl, where they accumulate as a solid mass.

• Replaceable Element: While some centrifugal filters have a permanent rotor that must be manually cleaned, this part number refers to a replaceable filter element or rotor insert designed to be swapped out during routine maintenance, ensuring consistent filtration efficiency and easy servicing.

• Specifications: According to product listings, this filter element has a standard size of approximately Φ97*122 mm and is compatible with specific applications, including DAF truck engines.

Maintenance Note:
The trapped dirt and sludge form a dense cake on the rotor's inner wall. During maintenance, the filter is disassembled, the solid deposits are scraped away, and the element is replaced to restore optimal performance. This design provides highly effective oil cleaning, especially for removing very fine particles that can pass through standard filter media.
