Permeability Tests

In order for powders and granular materials to exit storage silos and containers, air must flow through the powder mass. Permeability is the study of the air flow through a powder mass as various pressures are applied to the powder.

The EVOLUTION Powder Tester measures permeability using a sophisticated air pump to measure the pressure differential across a powder bed while varying the pressure on the powder bed.
