The Model K Vibra-Jet bin aerator has the extreme flexibility to throttle the compressed air as required to handle almost any dry bulk solid material which is finer than 20 mesh (800 micron), regardless of its bulk density. This feature also maximizes process performance and minimizes the compressed air demand, plus it reduces the overall energy requirements. Some unique construction features have been designed into the Model K Vibra-Jet bin aerator to prevent back feeding and truly set it apart from all other types of bin aerators available. This is extremely important because as the very fine dry bulk materials become fluidized and more flowable they can, under certain circumstances, backfeed into the air source. In addition, This model is easily installed and very adjustable.
