New B Grade Dynamic TB002 DN669 Stick Blender. The Dynamic Gigamix Mixer Variable Speed is even more advanced than our original model - with a range of variable speeds up to 4000 RPM, it is specially designed for heavy duty, high volume mixing. The impressive size accommodates for its 400 litre capacity and the variable speed option for greater flexibility. The Gigamix mixer also features an exceptionally sturdy, stainless steel construction which is highly robust and effortless to clean. Its heavy duty locking castors mean that although it is easy and safe to transport, it is also safe and secure when in operation, and its overall design means it is highly convenient to store. Ideal for use in commercial catering environments such as restaurants, canteens and hotels.
