Overview Precision group shower screen for La Spaziale machines. The screen gives off an even water distribution, allowing for better extractions, less channeling, and more body and roundness in your cup. Coated vs. Non Coated The coated shower screens have a protective nanotech coating which helps to eliminate coffee oil residue and build up, and makes cleaning much easier. However, this coating will breakdown overtime during back flushing (using detergent such as FCL500) so we advise you to remove it and replace it with a standard shower screen when performing your routine maintenance. Note: when installing, the smaller of the 2 screens goes on top/outside.
