Max J Series Cylindrical Venturi Vacuum Generator

Max J Series
The J-300 & 350 Series cylindrical venturi vacuum generators 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 3 models that can generate up to 28”Hg [948mbar] and 28 SCFM [793LPM] of vacuum flow.

These high vacuum flow generators are ideal for providing vacuum to large cups or a group of cups. When handling non-porous items like sheet metal, the J300 & 350 generators provide rapid evacuation to reach vacuum quickly for every high-speed handling. When handling porous materials these generators will overcome leakage and maintain a strong grip.

Lightweight, quiet and cool operating, J Series generators are ideal for confined spaces, where they can be mounted 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.
