Core Benefits for Extraction & Maintenance
The A.5.110 Diffuser Screw is a critical component for baristas solving "uneven water distribution on espresso puck" or "poor espresso extraction" issues.
-
Enhanced Steam Flush: The modified internal geometry facilitates a more efficient cleaning cycle, crucial for high-volume environments where group head hygiene is paramount.
-
Advanced Backflushing: Designed to allow deep cleaning of the shower screen without total disassembly. When used with a blind basket, the screw optimizes water turbulence to dislodge coffee oils and grounds.
