Examples of Proper Application Include:

Powders with fine granules

Concrete, stucco, grout, sand & refractory materials


The Model 720 air packer has a specially designed fluidizing air slide powered by an external source of low-pressure, high-volume air. Product flows by gravity from the supply hopper bin into the product feed inlet at the top of the machine. When a fill cycle is initiated, the product is fluidized by the air slide. The Model 720 is an automatic electronic scale gross weighing filler that simultaneously fills and weighs product directly into the bag.

Clean Operation:

The 720 series air packer has a totally enclosed product flow path from supply hopper all the way into the bag. It is equipped with a dust collection manifold which can be ducted to your plants dust suppression system. Together with our optional 111 Tube Cleanout, optional 116 Tapered Cone Assembly and a filling spout arrangement that is appropriately designed for your application, the Model 720 is the cleanest filling pneumatic (air) style valve bag filler available on the market.
