The multi-stage vacuum generators of the ZL250A series from SMC bring about 112% higher suction volume flow compared to a single-stage model. On the basis of the highly efficient 3-stage diffuser construction, they are very powerful. The lightweight powerhouses are also 8% narrower and 60% lighter.

This compactness, which is a trend, reduces the loads on the moving parts, especially in highly dynamic applications Industrial robotsn. At the same time, the air consumption has been reduced again by 10% compared to the previous models. This energy saving was achieved by lowering the operating pressure for the maximum vacuum from 0,4 MPa to 0,33 MPa. The air consumption is therefore only 57 l/min.

In the compact housing of the multi-stage vacuum generator, all elements are housed in a single unit: 3 stage diffuser, vacuum pressure sensor, pilot valves for supply and ventilation, and filter and silencer unit. This makes the ZL112A models very easy to maintain. For example, no tools are needed to replace the silencer or filter unit. With the push of a finger, latches can be opened and easy access to the parts to be replaced.

High vacuum, ultra high vacuum and extremely high vacuum

The ZL112A series is particularly suitable for use on workpieces in the packaging industry where high pressure leakage is to be expected, such as with porous or uneven surfaces, e.g. B. occurs in cardboard or wood materials. The weight-reduced design of the vacuum generator predestines it specifically for use on moving parts Industrial robotsn.

Depending on requirements, the ZL112A series models can be equipped with three different pressure gauges: In addition to the digital vacuum switch, a vacuum gauge and a vacuum connection adapter are available. Equipped with a digital vacuum switch, the pressure in the field can be read directly on the ZL112A vacuum generators. The current values ​​are shown on a display and the switching points can be changed quickly using pushbuttons.
