VUOTOTECNICA PVR50

Working principle These vacuum generators operate based on the Venturi principle. Unlike those previously described, the ejectors with which they are supplied are adjustable, in addition to having a considerably higher flow diameter. This detail lets them vary the flow rate and level of vacuum of the device, without altering the level of vacuum of the supply air. The compressed air consumption is also related to the actual performance of the vacuum generator. Features The special shape of these adjustable vacuum generators, as well as their straight-flow working principle allow sucking and transferring products of various nature with no interference, just like flow generators, only, unlike these, they allow overcoming much higher level differences. They are suited for transferring powders, granulated products, sawdust, metal chips, dry or liquid food products, etc. They are also recommended for controlling vacuum cups in presence of large amounts of dust or liquids, as well as for sucking fumes, cooling mists, water and oil condensation, etc. The absence of moving parts allows for a continuous use without developing heat. The noise level, which is quite high for this kind of equipment, can be considerably reduced with a silencer screwed on the exhaust connection. They do not require electricity, therefore, they can even be used in work environments with hazardous environments where an ignition source would be dangerous. Available in anodised aluminium and stainless steel. Thanks to all these features, a good filtration of the compressed air supply will be sufficient to make these devices fully maintenance-free.
