Pneumatic vacuum generators

The VU-type pneumatic vacuum generators provide in-line installation with vacuum pads and devices. The space-saving generators reduce the system’s footprint. Made of engineered polymers, the generators weigh between 7 and 22 gm.

Three models are available to meet varying pressure requirements, including high vacuum, medium flow (Model H); medium vacuum, high flow (Model L); and high vacuum, low flow (Model E). Service pressure (at 20°C) is 21.8 to 102 psi (0.15 to 0.7 Mpa); vacuum levels (at 73 psi, 50 psi for E) range from –19.7 to -27.2-in. Hg (66 to 92 kPa); and suction flow (at 73 psi, 50 psi for E) ranges from 0.25 to 0.9 scfm (7 to 24-lpm ANR).

The vacuum generators come in metric and inch sizes, with port sizes of ¼ and 5/32-in. ports as well as 4 and 6 mm. Six nozzle sizes are available including the popular 0.5 and 0.7-mm diameters.
