Vacuum Generator Maintenance Guidelines
Some E XATRON Changeover Kits contain a vacuum generator (a.k.a. "venturi") to create the vacuum
used in the operation of the specific kit.
Please refer to F IGURE 7-3 following this section for vacuum generator assembly mechanical details.
Please note that in some cases, the venturi assembly will not include the control valves. Please refer to
the manufacturer's data sheet, "P
ISCO Vacuum Switch," in Chapter 10 of this manual for additional
information.
To Order from E XATRON :
P ISCO VACUUM GENERATOR ASSEMBLY WITH CONTROL VALVES , PART #VGH10F-1/4-1/4.
P ISCO VACUUM GENERATOR ASSEMBLY WITHOUT CONTROL VALVES , PART #VGH10B-1/4-1/4.
R EPLACEMENT AIR FILTER , PART #VGFE10.
1. Inspect the vacuum generator's air filter weekly. The filter should be clean and white. These filters
can be cleaned, however, E XATRON highly recommends replacing dirty filters with new filters instead.
How frequently you need to replace the vacuum generator filter is a function of how clean your
environment is and how clean the devices being run are.
REMEMBER: A Dirty Filter = Poor Handler Operation.
