The JS-40UM (Ultra-Mini) cylindrical venturi vacuum generator is the smallest complete venturi vacuum generator that Vaccon offers. Incredibly compact and powerful – it measures the size of your finger tip and generates up to 27”Hg [914mbar]. Lightweight, quiet and cool operating, JS-40UM generators are ideal for confined spaces, where they can be mounted in-line near the point of use for rapid response.
The single-stage design allows ingested contaminants to flow through the generator without clogging ensuring continuous operation. Constructed of a single material, with no seals or moving parts, J Series generators are virtually indestructible. They can be manufactured in a variety of materials, making them ideal for use in adverse operating conditions. J Series generators provide a constant vacuum flow, rather than a fluctuating flow typically associated with diaphragm generators. They operate with an instantaneous response in pulsed applications or on a continuous basis.
The JS-40UM generator is used in the Vacuum Pencil KIt
for benchtop pick and place operations of small objects.
