MHW-3BOMBER Espresso Puck Screen 51mm

SKU a-FG5580S

MHW Espresso Puck Screen 51mm – 0.8mm Stainless Steel is a precision-cut mesh designed to promote even espresso extraction, preserve your group head, and improve post-shot cleanliness in your workflow.

Better Extraction with Every Shot

Crafted from SUS304 stainless steel, the MHW 51mm puck screen in 0.8mm thickness features a dense mesh with 11,848 holes, each just 0.18mm wide. Designed to sit directly on top of your coffee puck, it disperses the water flow for consistent saturation and isolates grounds from the group head, ensuring a cleaner machine and a more balanced shot. Perfect for enhancing espresso clarity and structure—especially useful with darker roasts or delicate flavours.

How the MHW Puck Screen Works

Mesh Barrier: Sits on top of tamped grounds inside the portafilter to promote even water dispersion.
Extraction Stability: Prevents channeling by diffusing water pressure across the surface of the puck.
Post-Extraction Cleanliness: Reduces coffee buildup in your group head, making cleanup faster.
Single or Double Layer: This version is the 0.8mm thick, single-piece mesh with no hollow centre.
