Pneumatic conveying (plastics - toner - talc - fire extinguishers - food - chemical - pharmaceutical etc.)

Used in a multitude of applications, to transfer powdery products without dispersion from the point of withdrawal to a container, molding unit, dosing unit or packaging unit. Other applications are transfer to production machines or in dry lubrication.

The filtration of these processes must therefore take into account the following specific parameters:

  • very variable particle size, often very fine and self-lubricating (risk of migration) or food grade
  • possibility of chemically aggressive (strongly acidic or alkaline) or moisture-reactive dust
  • presence of toxic, carcinogenic, mutagenic chemicals, etc.
  • high risk of agglomeration and gelling
  • possible risk of explosion
