Conveyor adjustable vacuum generators PVR 25 and PVR 50
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.

Accessories for conveyor adjustable vacuum generators
The noise level of Conveyor adjustable vacuum generators, which is always quite high, can be considerably mitigated by a suitable silencer screwed onto the air exhaust connection.
SSX series silencers can be supplied upon specific request. These are suitable for all Conveyor vacuum generators.
The table below shows the codes of the silencers related to the various vacuum generators.

Conveyor vacuum generator PVR 25 MS, with support for fastening to vacuum cups
The particular shape of this rectilinear flow vacuum generator allows for the supply of vacuum cups, especially in the presence of abundant quantities of dust, liquids, sawdust, of various origins, and shavings, without interference. It can reach a level of vacuum of -70KPa, a suction flow rate of about 10 m3/h, with a supply pressure of 3 bar.
The support it is equipped with allows it to be fixed to flat vacuum cups, starting from Ø 200 mm, while a special adapter, available upon request, allows the generator to be fixed at a distance. A "free-flow" silencer is installed on the intake air exhaust with high sound reduction, equipped with appropriate safety protection to prevent the dispersion of the sucked solid impurities in the work environment.
Also upon request, it is possible to supply a digital micro vacuum switch, item 12 05 11 P, for checking the level of vacuum inside the vacuum cup, and a vacuum gauge item 09 03 15, for direct reading of the level.
A good filtration of the compressed air supply will be sufficient to make these devices fully maintenance-free. Their use is recommended in particular on vacuum cups for gripping marble and granite, bricks, rusty metal sheets, rough wooden boards and anything else with especially dirty gripping surfaces.
