This unit is Footswitch operated & has an integrated scale under filling nozzle to weigh product as your container/bag is being filled. Filler will stop once weight has been achieved. All contact parts are stainless except there is a steel bracket welded onto the infeed of the hopper lid. Hopper has agitation as well as a level sensor. This is currently sitting on a steel frame & rides on casters. This was last used to run large containers of hot chocolate powder and is in good condition.
