8N6309 Air Filter for Caterpillar G3516 / G3512 / 3508 Series | Bowei Filter Factory
This heavy-duty air filter (490×250×250 mm) is designed for large diesel engines and industrial generator sets.
At our Bowei Filter Factory, we produce this model using high-strength steel mesh, uniform pleated paper, and a solid end-cap structure to deliver stable filtration performance in dusty and high-load environments.
Sometimes customers ask why our filter looks more rigid than others. The reason is simple — we use thicker metal mesh and tighter pleating density, something we insist on in our factory to make the filter last longer in real working conditions.

Manufacturing Highlights (Bowei Factory)
In our factory, this air filter is produced on automated pleating lines to ensure every pleat is straight and evenly spaced.
We also apply a double-layer metal mesh structure, which increases durability when the engine creates strong suction.
We are very strict about QC:
pleat uniformity check
mesh strength test
sealing inspection
airflow & resistance test
final manual inspection before packing
That is why many distributors choose Bowei over trading companies.
Durable End-Cap Structure
The steel end-cap provides excellent sealing strength and resists deformation.
This design suits high-temperature generator rooms and engines running long hours.
