Key Features and Characteristics (as seen or inferred from the image):
- Shape: Cylindrical/Round – This shape provides a large surface area for filtration within a compact design
- Filter Media: The white, pleated material visible inside the metal mesh is the filter media. This is typically made from:
- Pleated Paper: Most commonly, it’s a specialized, high-density paper media folded into pleats to maximize the surface area for filtration. This allows for higher airflow while effectively trapping particles.
- Synthetic Fibers: Some filters might use synthetic media, especially for specific applications or enhanced durability.
Outer Mesh/Cage: The metal mesh (often expanded metal or wire mesh) on the exterior acts as a protective cage. It provides structural integrity to the pleats, preventing them from collapsing under the suction pressure of the engine’s intake, especially as the filter accumulates dust.
End Caps: The black material at the top and bottom (visible in parts) are the end caps. These are typically made of rubber or polyurethane and serve to seal the filter within the air filter housing, ensuring all incoming air passes through the filter media.
