This option for the EconoMAX™ bulk bag filling system is standard for most filling application. It has a dual diameter fill spout in which the inner diameter is used as a product fill path and the outer diameter is used to hold the fill spout. The annular space created between the inner diameter and the outer diameter is used as the path for dust removal. On the outer diameter, there is an inflatable bladder (which is covered by a rubber sleeve) that will inflate after the bag spout has been slid over the fill spout, and the operator initiates the action, this creates a dust-tight seal and holds the bag spout in place throughout the fill cycle. The actuation of the bladder will be done and supplied using a manual style “joystick” type pneumatic valve located on the end of the bag arms and must be actuated by the operator while hanging the bag prior to the fill cycle.
