Folding impellers allow the use of a large impeller in a closed container due to their unique collapsible blade design. Our 4" and 7" folding impellers can fit through a 2" NPT fitting and our 10", 12" and 14" folding mixer impellers can fit through a 6" NPT like that on an IBC Tote. With our folding mixers, agitation can now be accomplished in areas that were otherwise inaccessible to mixing equipment. Constructed of 316 stainless steel, these folding impellers provide a high level of chemical and abrasion resistance.
