G9WD-RH specifications

The Bunn G9WD-RH is a premier commercial coffee grinder designed for high-demand environments, such as cafes, restaurants, and coffee shops. Renowned for its efficiency, durability, and consistency, this grinder is an essential piece of equipment for any establishment that values quality coffee.

One of the standout features of the Bunn G9WD-RH is its powerful grinding capabilities. Equipped with a 1.1 horsepower motor, it can easily handle high volumes of coffee beans, making it ideal for busy locations. This grinder operates at a speed of approximately 3,600 RPM, allowing for quick and uniform grinding, which is crucial for achieving optimal flavor extraction.

The G9WD-RH utilizes a unique patented design for its burrs. The burrs are made of high-quality stainless steel and provide a precise grind size that can be easily adjusted.
