Professional FAQ: Technical Aspects of Weichai Engine Oil Filter

Q1. What is the precise filter media structure used in Weichai Engine Oil Filters?

A: The filter core utilizes a hybrid of synthetic glass fiber and cellulose, arranged in multi-layer pleats. This arrangement ensures a high dust-holding capacity while maintaining minimal differential pressure—key for consistent oil flow in severe duty cycles.

Q2. What is the micron rating and why does it matter?

A: Micron rating defines the minimum particle size trapped—in Weichai Engine Oil Filter, it is 12–25μm. Lower ratings mean finer particles are filtered, reducing engine wear and prolonging oil life.

Q3. Which international installation standards are supported?

A: All mounting threads & gaskets comply with SAE J512, DIN 4762, and Weichai OEM standards for easy retrofit and secure fitment.

Q4. How is burst strength tested?

A: Filters are subject to hydraulic burst testing (ISO 4548-6), requiring a minimum of 1.3 MPa before rupture. Each batch is validated in-house and randomly checked by third-party SGS labs.

Q5. Are the filter seals resistant to modern synthetic engine oils?

A: Yes, NBR rubber or optional Viton is used—tested for 720h in contact with full-synthetic and high-alkaline diesel oils according to ASTM D471.

Q6. How often should Weichai Engine Oil Filter be replaced?

A: For standard highway trucks, replacement is recommended every 35,000–50,000 km or every 500–600 hours for off-road engines. Heavy mining or metro fleets should adhere to oil condition monitoring as well.

Q7. Can you provide traceability and anti-counterfeiting?

A: Yes, every Weichai Engine Oil Filter has a unique laser marking and QR code linking to its test data and origin, supporting end-user verification.
