JIFFY MIXER is an all purpose, heavy duty, extremely efficient industrial/commercial mixer. It is designed to quickly and thoroughly mix dense and viscous substances in an open container. It eliminates waste and unwanted aeration of materials in addition to cutting mixing time up to 90%. It is equally effective with liquids, dry materials, liquid and dry materials combined, or multiple component materials. Made of polished stainless steel 304, its construction and design is for mixing, not just stirring. Its various sizes fit standard 1/4", 3/8", 1/2", 3/4" chucked power tools. 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.
