The 51mm Delonghi HD Kit
Water dispersion is the foundation of great espresso. Get it wrong, and you increase the chance of channeling, weak, flavourless shots no matter how good your beans are. This kit tackles the problem at every stage of the shot, from pre-infusion through to extraction.
1. 51mm HD High Diffusion Shower Screen
18 integrated channels direct water to the exact same positions across the entire puck bed, every single time. During pre-infusion, when the puck is most vulnerable to uneven soaking, this consistent diffusion stops micro-channeling before it starts, before pressurisation exaggerates it into a ruined shot.
2. 51mm EP Electro Polished Filter Basket
Reduced friction means the liquid flows more freely through the basket and sides. The result: smoother, more consistent coffee flow and balanced, reliable shots, extraction that matches the even dispersion up top.
3. Free 0.2mm Contact Mesh
Sits on top of the puck to retain its structure, further reducing channeling and improving diffusion. Bonus: it keeps your HD shower screen cleaner for longer, so there's less maintenance between pulls.
Together, all three components work as a system, even dispersion, low-friction extraction, and puck protection, so every shot pulls the way it's supposed to: full-bodied, balanced, and repeatable.
