Professional upgrade kit for manual flow control in the E61 bridge group.
Adjustment of the flow rate at which the water in the brewing group hits the coffee.
This extension allows you to vary another factor for espresso extraction in addition to grinding and weight. With a low flow at the beginning of the brewing process, the risk of uneven extraction is minimized.
Fits all Profitec and ECM espresso machines with E61 brew grip. If you are unsure, please contact us and we will help you.
