Yes, the M4 is specifically designed to work exclusively with Fiorenzato F64 and F83 grinder models. The mounting system and dimensions are engineered to stack perfectly with these grinders, creating an integrated grinding and tamping station.

The M4 is available with four piston sizes: 58.3mm, 58mm, 57.3mm, and 54.3mm. The 58.3mm is most common for commercial applications, while the 54.3mm works well with smaller portafilters used in some specialty applications.

By mounting directly under your Fiorenzato grinder, the M4 uses zero additional counter space. The stacked configuration typically saves 9-12 inches of counter depth compared to a separate tamping station, crucial in busy café environments.

Absolutely. The M4 is built for commercial environments processing over 66 pounds (30kg) of coffee weekly. The 1.3-second cycle time and robust construction ensure it keeps pace with the busiest coffee services without missing a beat.

The LCD display allows you to adjust tamping pressure from 22-66 lbs (10-30kg) in precise 2.2 lb (1kg) increments. Simply use the adjustment buttons to dial in your preferred pressure, which is then consistently applied to every tamp.

Yes, the M4 features universal portafilter compatibility with an adjustable lower clamp height. It works with all commercial portafilter brands and styles, including both single and double spouts, bottomless portafilters, and various handle designs.

Minimal maintenance is needed thanks to the non-stick tamper finish. The one-touch cleaning button disables the piston for safe cleaning. We recommend wiping the tamper head periodically and checking the adjustment mechanisms monthly for optimal performance.
