Patent number: ZL2010102100538840
Flat metal mesh structure is unreliable, and it is not easy to locate during installation. Strength of flat metal mesh is not enough, so the air filter is easy to deform, which reduce its service life. In order to improve the strength of the metal mesh, products of our company are set a certain number of arcs in mesh surface according length to increase the strength and stress tolerance.
