Know before you buy
This screen is specifically designed as a direct retrofit for ROK and Presso espresso makers equipped with the GC (Glass Composite) brew chamber. It will not fit older models that do not feature the GC chamber.
Traditional screens often have a bolt in the center that can disrupt water flow. By removing this, the ROK Competition Screen allows for a more uniform, laminar flow of water across the entire coffee puck, which helps prevent channeling and promotes a more balanced extraction.
Yes, the screen acts as a barrier that prevents coffee grounds from migrating back into the brew chamber. This keeps the internal components cleaner and makes your post-brew cleanup significantly faster.
The 300-micron rating is the 'sweet spot' for manual espresso brewing. It is fine enough to filter out unwanted sediment while remaining porous enough to ensure consistent water flow without creating excessive backpressure.
The screen comes with an overmoulded food-grade silicone seal already attached. It is ready to install directly into your machine right out of the box.
