MATRIX concave shower screen in marine-grade AISI 316L stainless steel, with a porous microsphere structure and 4 to 5 µm channels instead of conventional holes. Water at 9 bar is forced through thousands of micro-channels and turned into micro-droplets and nanobubbles, for a denser crema and even extraction. For groups using the E61 standard.
It is made for E61-standard groups, such as Wega, Rocket, ECM, Vibiemme, Rancilio, La Marzocco and Bezzera. If the group's diameter is non-standard, measure the seat first.
What is the microsphere structure?
The body is made of bonded steel spheres, leaving thousands of 4 to 5 µm channels between them. Water passes through that dense network and comes out far finer.
Does it really improve crema?
The micron channels create nanobubbles and spread water evenly; many baristas report a denser crema. The result also depends on the coffee and the grind.
How do I clean it without damage?
With a dilute solution and regular backflush. Do not use abrasive powders, needles or pads, which damage the porous structure.
Do you ship and quote?
Yes, to Portugal and across Europe. For availability, request a quote.
