Medway Mistral Air Packer

The complete solution for valve sack applications

The Mistral valve sack filling machine offers high speed packing of powders and granular materials and also mixtures of these products.  The machine is complete with its own weighing system.

The Mistral air Packer is of the fluidising type, using air to convey the material into the sack.  The material enters the machine through a control valve into a conditioning chamber and a porous pad is fitted at the base to provide aeration. A cut-off valve allows the material to pass through the filling tube and into the sack.  The base of the sack is supported on a pivoting saddle which is also used to discharge the filled sack.  A blower may be supplied to provide the air for aeration of the material.
