787 Force Flow Packer Valve Bag Filling Machine

The Model 787 Force Flow Packer is a simple, rugged, economic, easy to operate filling machine. Multiple units may be banked together under a single hopper to provide higher production rates.

The Model 787 is engineered to fill all types of valve bags with a wide range of products from powders to granules or pellets producing a weighing accuracy of +/- 4-8 oz. @ 2 standard deviations on most products.

Features
  • Low-pressure air fluidizes the product causing it to flow freely and more uniformly which results in greater accuracy.
  • Simple fine weight adjustments make product or container changes quick and easy.
  • The enclosed flow path and pneumatic pinch tube cutoff combine to produce a relatively dust free operation.
  • Single-beam, low maintenance type scale system.
  • Air bag clamp and manual tilting bag rest optimize bag support and provide easy bag discharge.
