Mid J Series Cylindrical Venturi Vacuum Generator

Mid J Series Cylindrical Venturi Vacuum Generator
The J-100 and J-150 models offer the same performance as their sister generators, the J-100M and J-150M Min Series generators, but with larger ports. The J-200 and 250’s offer higher vacuum flows for rapid evacuation of large vessels and to overcome leakage to sustain high vacuum levels while handling porous materials. Choose from 6 models that can generate up to 28”Hg [948mbar], and 10 SCFM [283LPM] of vacuum flow.

Lightweight, quiet and cool operating, J Series 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.
