Vacuum auto loaders are used to transfer pellets, regrind and powders from a single source to a single destination (usually a blender, drying hopper or machine throat). A pickup lance is inserted into the material source container and a length of flexible hose connects the lance to the loader. The loader is mounted on top of the destination point and a small powerful motor creates a vacuum that sucks the material up through the pickup lance and flexible hose into the body of the loader.
