Spectropur Vacuum venturi VAK 200

Spectropur Vacuum venturi VAK 200

  • By applying a vacuum in the course of a purge cycle the dilutional effect of purge and process gas can be improved significantly.
  • The vacuum venturi VAK 200 offers a simple and cost-effective alternative to a vacuum pump and can achieve an effective vacuum of up to 200 mbar (abs) with a propellant gas pressure of approx. 7 bar.
