Suited for demanding mixing applications, Model EHR 23/2.4 S Set has load speed of 0–250 and 0–580 rpm. Variable speed mixer is equipped with heavy-duty galvanized paddle that can handle high-viscosity materials in batches up to 200 lb, including epoxies, mortars, plasters, cement, quartz-containing resins, and flooring compounds. Featuring helical design, paddle mixes batch from bottom up, preventing splash and keeping air from being sucked into material.
