30" x 2.5" with a 1/4" shaft. Mixes 1-2 gallons. Up to 800 RPM. Stainless Steel. It has two sets of specially welded blades. The vertical ones keep the mixing action between them, the horizontal ones employ an exclusive hydraulic-flow principle that prevents sucking air. In addition, the horizontal blades pull the high density material up from the bottom while forcing the low viscosity solvents down from the top. All stress joints are specially welded for extra strength so it is virtually impossible for them to break.
