Cylindrical Venturi Vacuum Generators (J Series)
The J-Series Venturi Vacuum Generators utilize a fixed venturi design, manufactured for inline use employing a cylindrical body for ease of installation and mounting near the point of use for rapid response. Lightweight, quiet and cool operating, J-Series generators offer a complete range of venturi vacuum performance, with vacuum levels up to up to 28"Hg [948mbar] and vacuum flows from 0.5 to 28.0 SCFM [14.2 to 792.9 L/min]. The J Series generators can be manufactured in a wide range of materials for chemical compatibility and environmental requirements.
- Ultra-Small - The JS-40UM (Ultra-Mini) cylindrical generator is the smallest complete venturi generator that Vaccon offers. Incredibly compact and powerful – measuring the size of your fingertip while generating up to 27”Hg [914mbar].
- Compact Design - The J Series “M” (Mini) generators feature 11 models with a high power-to-size ratio, generating up to 28”Hg [948mbar] and 3.5 SCFM [99 LPM] of vacuum flow, in a unit measuring only 3” long by 3/4” in diameter.
- The Mid and Max J Series generator offer higher vacuum flows for rapid evacuation of large vessels and to overcome leakage to sustain high vacuum levels while handling porous materials.
