1.1 Definition and core functions
The Air Filter For Compressor is a core component used to filter particulate impurities in the engine intake air. It protects key components such as cylinders and pistons from wear by intercepting harmful particles such as dust and gravel, thereby extending the engine life and improving fuel efficiency. Its technical classification includes dry type (paper/non-woven fabric) and wet type (metal mesh/polyurethane sponge), accounting for approximately 75% and 25% respectively.
1.2 Industry chain structure
Upstream: raw materials (polypropylene fiber, polyurethane, metal mesh) and equipment suppliers.
Midstream: filter element manufacturing and integration (OEM and aftermarket).
Downstream: applications in automobiles, engineering machinery, industrial equipment and new energy fields.
1.3 Application Areas
| Application scenarios | Demand share | Technical requirements |
| Passenger cars | 45% | High filtration efficiency, lightweight |
| Commercial vehicles | 30% | High temperature resistance, long life |
| Construction machinery | 15% | Moisture-proof, vibration-resistant |
| Industrial equipment and new energy vehicles | 10% | Low resistance, adaptable to electric intake system |
