IMS Precision E61 Group Screen - 60mm, 200 Micron A gasket-retained (no screw) shower screen for E61-style group heads, built by IMS to the same 200 micron spec as their screw-type screens. Because it's held in place purely by the group gasket's compression, it's about as close to a drop-in fit as shower screens get on E61 groups. SPECIFICATIONS Outside diameter: 60 mm 98 perforations at ø 3 mm AISI 304 food-safe stainless steel with integrated 200 micron membrane COMPATIBILITY Fits: E61-style group heads on select models from Ascaso, Azkoyen, Bezzera, BFC, Bianchi, Brasilia, Casadio, ECM, Expobar, Faema, Faimac, Fiamma RST, Fiorenzato, Grimac, Iberital, Italcrem, La Nuova Era, Orchestrale, Promac, Reneka, Royal, Sab Italia, Sanremo, Scala, VFA Expres, Vibiemme, and Wega, not every model from every listed brand uses this exact screen, so confirm your machine takes a gasket-retained (no-screw) screen first Works with: the OEM E61 group gasket, which holds the screen in place without a separate screw INSTALLATION Easy DIY swap, no screw to remove, the screen simply seats against the gasket. PRO TIPS If your current screen is held by a screw, this is the wrong screen, don't force a no-screw screen into a screwed group. Check the back of your old screen for a screw hole before ordering.
