Eheim Lattice Screen for Classic 150 (2211) (7271808) The Eheim Lattice Screen (7271808) is a genuine OEM replacement lattice screen designed specifically for the Eheim Classic 150 (2211) external canister filter. The lattice screen prevents filter media from clogging the in-flow of water and from restricting the outflow from the motor head — vital for the proper function of the filter — and allows water to be properly displaced throughout the filter media. Home page Positioned inside the filter canister, the lattice screen acts as a physical barrier that holds filter media in place while allowing unrestricted water flow through the filtration stages. Over time the screen can crack, warp, or become damaged — compromising media placement and water flow distribution inside the filter. Replacing with a genuine Eheim OEM lattice screen restores correct media separation and full filter performance.
