Asymmetric Sintered Metal Filter

The outer layer features larger pores to capture coarse particles, while the inner layer provides finer pores for precision filtration. This creates an integrated two-stage filtration mechanism within a single filter element.

Compared with conventional single-layer sintered metal filters, the asymmetric structure delivers improved permeability, lower pressure drop, higher dirt-holding capacity, and longer service life.

These filters are particularly suitable for applications requiring both high flow rates and stable fine filtration performance.
