These highly effective, quiet power units are a VAC-U-MAX innovation. They are ideal for low rate, intermittent use where sufficient plant air is available when required. Simple in construction and operation, the venturi power units have no moving parts and thus require minimum maintenance. Regular shop air, reduced to 60 psig, is passed through the venturi, developing a powerful vacuum which draws air and material through the conveying lines. Variable orifice normally set for 8" HG vacuum can be adjusted to a maximum of 16" HG.

Venturi power units are available in single to quadruple venturi versions. Cycling can be controlled manually with a manual air control valve or automatically utilizing an air control valve actuated by a timer control panel or by a signal from other control devices. A patented muffler system keeps sound levels well below OSHA limits.
