Vac-Stac Series of venturi vacuum generators are designed specifically to integrate with all ISO 5599/1 Size-1 directional control valves. Vaccon's Vac‑Stac generators provide the quickest and most efficient way to incorporate vacuum with individual ISO valve bases or manifold assemblies for automation applications including pick & place and material handling operations in packaging, automotive and food processing industries.
Similar to “sandwich” flow control valves or pressure regulators, Vac-Stac generators offer Original Equipment Manufacturers (OEMs) and machine designers an efficient solution to control air and vacuum in one compact unit. Modular, lightweight and easy to install, Vac-Stac generators are compatible with any manufacturer's ISO 5599/1 Size-1 valves including SMC, Numatics, Festo, Parker and others.
Vac-Stac generators eliminate the need for separate vacuum generators and air lines, minimizing the number of pneumatic components and fittings saving money, time, and space. Installation is quick and easy, simply remove the ISO valve body from its base, mount the Vac-Stac generator to the valve base, and reattach the valve body to the combined generator/base. Vac-Stac generators add less than 2 inches to the valve stack height and can be easily retrofitted into existing equipment and systems.
Vac-Stac generators are available in 11 different performance levels up to 28” Hg [948 mbar] vacuum level and 3.2 SCFM [90.6 LPM] vacuum flow. As with all Vaccon products, the Vac-Stac series generators operate continuously without maintenance or costly filters, eliminating downtime, increasing productivity and improving profitability.

Vac-Stac Series Generator Operating and Installation Requirements
||0-10”Hg, [0 to 339mbar] for l vacuum/high flow applications
||0-20”Hg, [0 to 677mbar] for medium vacuum/high flow applications
||0-28”Hg, [0 to 948mbar] for high vacuum/standard flow applications
|The ISO 5599/1 valve top must be separated from the valve base to install the Vac-Stac venturi vacuum generator. Please refer to ISO 5599/1 valve manufacturer’s documentation for instructions.
||Mounting screws are included with ISO 5599/1 valve, however, these screws will have to be replaced with similar screws that are 1.25” [32mm] longer to account for the additional height of the generator. Please refer to valve manufacturer for screw specifications
