CV20948 Air Filter for Diesel Engines | Bowei Filter Factory
The CV20948 air filter is engineered for medium-to-large diesel engines operating in generator sets, construction machinery, and industrial environments.
At our Bowei Filter Factory, we build this filter using high-efficiency pleated paper, thickened iron mesh, and a reinforced end-cap design to ensure stable airflow even under heavy engine suction.
This model has a tall cylindrical structure (524 mm), so we increase the mesh tension and use more pleats to prevent deformation during long-hour operation — something our factory has prioritized over many years of manufacturing.

Bowei Factory Manufacturing Quality
Inside our factory, the CV20948 undergoes:
Automated pleating for uniform spacing
Precision mesh wrapping with strong tension
End-cap bonding at controlled temperatures
Airflow resistance testing
Final manual QC before packaging
We are constantly improving production details to deliver filters that survive dusty, high-load generator rooms and continuous-running diesel engines.
We added a thickened iron mesh detail view to show the exact reinforcement used in the CV20948.
This durable mesh prevents collapse and maintains pleat alignment, ensuring stable filtration during heavy-duty operation.
