Fans Special Process

Your project incorporates a fan. In spite of many documents at hand, you are not finding the appropriate machine in the catalogues.

A fan is however always an apparently simple device, just intended to move air or gas ; but this time, additional and unusual requirements complicate the deal :

  • the air is associated with a number of abrasive metal oxide particles.
  • no special steel, even no stainless steel, would resist corrosion in your process.
  • your 850C furnace needs gas circulation to equalise its temperature.
  • your circuitry requires gas tightness as an inert atmosphere is a necessity.
