FILTER DEVICE TO REMOVE PARTICLES FROM A VAPOUR STREAM

      
Application Number EP2015077925
Publication Number 2016/096377
Status In Force

  • Commandeur, Colin
  • Beentjes, Petrus Cornelis Jozef

Abstract

The invention relates to a filter device for reducing the amount of non-vaporous components in a vapour stream, comprising a carbon foam as filter material that is capable of being penetrated by the vapour stream and that is arranged in such a way that the only route for the vapour stream to pass the carbon foam is via penetration of the carbon foam. The device is in particular suitable for coating a substrate by physical vapour deposition of the vapour. The homogenous and single phase vapour stream produced by the filter device results in a smooth coated substrate wherein splashes are virtually absent.
