Powerful Mixing While Staying Portable. The AOX is a versatile mixer that is ideal for thin-bed mortar and fillers. This compact rotary mixer provides excellent mixing results due to the extra counter-turn motor under the mixing tub. The mixer has an auto safety device, which stops it when the guard hood is opened. The edge and bottom scraper are adjustable and the wheels on the bottom of the mixer make it mobile. This mixer is ideally suited for use at small and medium-sized construction sites.
