Product Description

How to distinguish the quality of tractor air filters? update:2025-06-16
First, look at the material and structure. High-quality filters use multi-layer composite fiber paper with a filtration efficiency of ≥ 99%. Secondly, observe whether the sealing ring has good elasticity and high-temperature resistance rubber to ensure sealing performance. Inferior products may use recycled rubber, which is prone to aging and cracking. Then, the air filter breathability test shows that the low resistance air circulation is smooth and does not affect the engine power.

Next, we will use text + icon + image + test data to show the product performance. Please be patient, we'll surprise you.
