Inlet Switcher Model GCVI-I


Automatically switch between ISO and CVI inlets, clear-sky and GCVI inlets, or any two sample lines using the Inlet Switcher: a custom 3-way valve with a straight-through flow path.

The Inlet Switcher is a convenient way to automatically switch between any two inlets with flow rates up to 20 lpm and particles smaller than 10 micrometers. The unique straight-through flow path design of the three-way valve minimizes particle losses while matching the up and downstream flow tubing inside diameters. Move the 3-way valve in just a few seconds by providing either a 5 volt DC or 100-240 volt AC control signal to the rack mountable chassis. The GCVI-I is automatically switched when integrated with the Model 1205 GCVI so instruments can sample from a clear-sky inlet when no cloud is present at the site.
