Vacuum Venturi VAK 200

spectro pur

Dimensions: Vacuum Venturi VAK 200 propellant gas waste gas

Vacuum Venturi VAK 200

Product features

• All gas-wetted parts made of stainless steel

SS 316L

• High surface quality

• Connectors: In-/Outlet UNF 9/16-18

(1/4” VCR-compatible)

Product description

• 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

Specifications

•

• SPECTROPUR - components guarantee maximum quality by using high grade materials

All parts which come into contact with the medium are cleaned in an ultrasonic cleaning system (CFC-free) with the special cleaning process SPECTROCLEAN and are then baked out. They then undergo the MEGACLEAN process in a cleanroom class 100/10, are

® assembled and packed in PE foil under an atmosphere of inert gas.

• SPECTROPUR - components undergo a 100%

Helium-leak-test and optionally a particle test

• Analysis of the metallic surfaces by the methods AES, ESCA and SEM (scanning electron microscopy) are available upon request.

Important note regarding component selection

• In order to assure safe operation it is essential to take the configuration of the whole system into account when selecting components.

• The function of the vacuum venturi, the compatibility of the materials, correlating temperature ranges, correct installation, operation and maintenance in accordance with the relevant regulations are the responsibility of the system designer and the user.
