Mazzer Robur S Electronic 3.5 lbs On-Demand Espresso Grinder, 500 RPM, Matt Black

The Mazzer Robur S is a commercial on-demand espresso grinder built for high-volume restaurant and cafe environments. Crafted in Venice from aluminum die casting, it delivers a sturdy, professional-grade build suited for the demands of a busy commercial kitchen or espresso bar.

At the heart of the Robur S is a 71mm conical burr set spinning at 500 RPM, paired with a 3.5 lb hopper capacity. Micrometric grind adjustment allows baristas to dial in grind size with precision, while three programmable dosing time settings via the electronic control panel keep service consistent across shifts. The adjustable portafilter holder accommodates a range of portafilter sizes commonly used in commercial espresso setups.

The GFC (Grind Flow Control) System manages coffee flow for uniform dose delivery, and the Memory Track System records usage data to support maintenance scheduling. A double fan cooling system helps manage operating temperatures during extended use periods. IoT connectivity allows the grinder to be monitored and configured remotely, a useful feature for multi-station commercial kitchen operations. The unit runs on 120V at 800 watts and measures 9.25" (W) x 11.5" (D) x 28.5" (H), with a product weight of 62 pounds.

The Mazzer Robur S carries ETL Listed, ETL Sanitation Listed, CE, VDE, GS, KC, EAC, RCM, and Espresso Italiano certifications, reflecting its compliance with a broad set of commercial and international safety standards. It includes a 1-year warranty by the manufacturer.
