Single-stage vacuum generator operation is based on the Venturi principle.
Supplying the generator with compressed air in P, vacuum will be generated at connection U, while both the supply and the sucked air will be released through R.
By interrupting the air supply in P, the vacuum effect in U will also stop. The optimal air supply pressure is normally 6 bar, but for generators with the letters LP in their item, a pressure lower than 4 bar is sufficient to obtain the best performance. Upon request, the vacuum generators can be supplied with a high sound suppression silencer installed on the R exhaust connection.
The single-stage vacuum generators are generally used to control vacuum cups, for gripping and handling non-porous objects and equipment with low flow rate requirements.
They are fully made with anodised aluminium, with brass or aluminium ejectors, depending on the items.

Single-stage vacuum generators with ejector 15 02 10, 15 02 10 LP and 15 02 15 LP
This single-stage vacuum generator operation is based on the Venturi principle. When the generator is supplied with compressed air in P, the vacuum will be generated at connection U and the supply air with the suctioned air will be discharged in R. During the operating cycle, a chamber inside the generator body will be supplied and, when supply stops in P, the compressed air accumulated in it will be discharged through the U connection, quickly the restoring atmospheric pressure of use.
If when using U, for example, it is connected to a vacuum cup, it will disconnect much faster with this ejector system with respect to the previously described vacuum generators. The optimal air supply pressure is normally 6 bar, but for generators with the letters LP in their item, a pressure lower than 4 bar is sufficient to obtain the best performance. They are fully made with anodised aluminium, with brass or aluminium ejectors, depending on the items.

VACUMANAGER VM series units are integrated electro-pneumatic circuits designed to supply and manage single-stage and multi-stage vacuum generators.
VM units house the following in an anodised body/distributor machined from billet aluminium:
- 1 Digital vacuum switch with display
- 1 Compressed air supply valve
- 1 Blow off valve
- 1 Flow regulator for the blow off valve
A compact electro-pneumatic control circuit that incorporates all components for the management of vacuum and blow off generation in a handling system equipped with vacuum cups and powered by pneumatic vacuum generators (single-stage or multi-stage).
In combination with the Vuototecnica Energy Saving cables, these represent the best solution in terms of energy efficiency, as they limit the consumption of the compressed air supplying the pneumatic vacuum generators to the time strictly necessary to empty the vacuum cups.
This energy-saving solution is even more valued and appreciated in all vacuum cup handling operations for products with excellent sealing or with micro-porosity (metal sheets, glass, wood or plastic veneered panels, etc.).
Vuototecnica also recommends VM units for handling all Octopus gripping systems equipped with pneumatic vacuum generators and shut-off valves.
Product codes: VM01 VM03
Single-stage and multi-function vacuum generators, MSVE series
The vacuum generators of this new series can fully drive a negative pressure gripping system. By means of coaxial shutters, the original compressed air supply system feeds large quantities of air to both the ejectors and the ejection system, thereby ensuring faster gripping and release of the load. These vacuum generators are equipped with single-stage ejectors, are powered by low pressure (max. 4 bar), and feature an extremely high emptying speed in relation to their suction flow rate. All this allows for increasingly faster high-performance work cycles. Two micro solenoid valves manage the compressed air supply to the vacuum ejector and adjustable discharge blow off. The intensity and duration of the latter are managed through a screw-type flow regulator. The check valve built into the suction connector maintains the vacuum in the event of a power outage. A digital vacuum switch, equipped with a display and commutation LED, manages the compressed air supply and provides a signal to start a cycle under safety conditions. An anodised aluminium distributor with vacuum connectors has an integrated suction filter that can be easily inspected. By activating the compressed air power micro solenoid valve, the generator creates vacuum for use. As soon as the set maximum value is reached, the digital vacuum switch acts on the electric coil of the micro solenoid valve and stops the air supply, reactivating it when the vacuum falls below the minimum level.
Besides maintaining the vacuum level within set safety values (hysteresis), this modulation allows for considerable compressed air savings. A second signal from the vacuum switch (also adjustable and independent with respect to the first) can be used to start the cycle when the vacuum level reached is suitable for use. Once the work cycle is completed, the micro solenoid valve that supplies compressed air to the generator is deactivated while, at the same time, the ejection solenoid valve is activated for quick restoration of the atmospheric pressure upon use. The MSVE vacuum generators can be installed in any position and are suitable for suction gripping systems, handling metal sheets, glass, marble, ceramics, plastic, cardboard, wood, etc. and, in particular, for the industrial robotics sector, where equipment with excellent performance and limited weight and bulk are increasingly required.

Single-stage and multi-function vacuum generators series AVG – General information
These generators are independent vacuum units capable of driving a vacuum gripping system They have been specially designed for the AUTOMOTIVE sector and they are equipped with single ejectors that, given the same flow rate as the multi-ejector generators, allow for a quicker grip.
They are provided as standard with a built-in pneumatic energy-saving device.
They are composed of an anodised aluminium mono-block structure, inside of which are installed the ejectors, the servo-controlled slide valve for the compressed air supply and are contained the vacuum chambers as well as the various connections.
The following are instead installed on the outside:
- A bistable impulse solenoid valve for controlling the slide valve.
- A solenoid valve for blowing the ejected compressed air.
- A flow regulator for dosing the ejected compressed air.
- Two silencers for removing noise from the ejected air.
- An aluminium manifold provided with vacuum connections with built-in:
• A pneumatic vacuum switch for managing the compressed air supply according to the set level of vacuum (energy saving).
• A check valve for maintaining the vacuum in case of electricity or compressed air failure.
• A suction filter, easy to inspect through the transparent polycarbonate lid. OPERATION
By providing an electric impulse to the two-position solenoid valve, the compressed air supply slide valve will be activated and vacuum will be created at the application. Once the preset maximum value has been reached, the pneumatic vacuum switch acts on the servo-controlled valve and interrupts the compressed air supply, restoring it when the value returns below the minimum value.
Besides maintaining the level of vacuum within preset safety values, this modulation also allows a considerable saving of compressed air and occurs even in the absence of electricity. Once the work cycle is completed, the power supply solenoid valve is deactivated by means of an electrical pulse while, at the same time, the ejection solenoid valve is activated for quick restoration of the atmospheric pressure of use.
AVG vacuum generators are fitted for the installation of a digital vacuum switch. Also these vacuum generators can be installed in any position. SECTORS OF USE
AVG vacuum generators are suitable for suction gripping systems, for the handling of metal sheets, glass, marble, ceramics, plastic, cardboard, wood, etc. and, in particular, for the AUTOMOTIVE sector, where equipment with excellent performance and limited size and weight are increasingly required.
Multi-stage vacuum generators - General description
Our multi-stage vacuum generators produce a maximum vacuum of 90%, equal to a final vacuum level of 100 mbar abs., with different suction capacities. They operate by use of compressed air from 1 to 6 bar. Working principle
Each ejector is based on the Venturi principle: the supply fluid (compressed air) is led high speed by a convergent pipe into the fluid to be extracted (volume of the air to be sucked). This mixture is then led into two or three divergent pipes, where its kinetic energy is transformed into pressure energy for it to enter in the environment at a higher pressure (atmospheric pressure at the exhaust). Technical features
The main asset of multi-stage vacuum generators is its ability to exploit the kinetic energy of the supply compressed air via several specially dimensioned in-line ejectors, before releasing it in the atmosphere. This system allows, given the same capacity, a reduced compressed air consumption compared to the single-stage vacuum generators.
The suction flow rate is indirectly proportional to the differential between the pressure of the fluid to be sucked and the external (atmospheric) pressure.
The reduced size and weight make multi-stage vacuum generators compact in relation to their great suction capacity.
The absence of moving parts make them particularly silent and allow them to be used continuously, without developing heat. Being supplied exclusively by compressed air, these vacuum generators are explosion-proof and can be used in work environments with temperatures ranging from -20 to +80 °C.
They are fully made with stainless materials.
Thanks to all these features, a good filtration of the supply and sucked compressed air is sufficient to make these generators are fully maintenance-free.
These new design vacuum generators feature multiple state of the art ejectors assembled onto small modules. One of their distinctive features is their great suction flow rate compared to their reduced size.
With a compressed air supply of 4 - 5 bar, they can produce a maximum vacuum equal to 85% and a suction flow rate of 3.6 - 18 m3/h, according to the number of modules.
The silencer is built-in.
They are fully made with slightly anodised alloys and can be installed in any position. The multi-stage vacuum generators in this range are suited for interconnecting vacuum cup gripping systems and, in particular, in the industrial robotics sector, which requires equipment with excellent working performance, but with weight and size reduced to the minimum.
Product codes: M3 M7
These vacuum generators share the same technical features as the others of the M series described above. Their distinctive feature is their silent operation.
In fact, along with the built-in silencer, they also have an external SSX silencer for a further noise reduction.
These generators are particularly recommended in work environments where the noise level must be kept within very low values.

Multi-stage, multi-function and modular vacuum generators, series GVMM – General description
Modular multi-function vacuum generators are true independent vacuum units that offer an entire vacuum control system.
They feature a reduced thickness and weight compared to their suction flow rate and they have been designed to be assembled with screws to one or more intermediate modules MI. The original internal connection system for the compressed air supply allows communication with no need for external manifolds.
This modular system allows increasing the number of independent vacuum units according to the requirements. In fact, you can order a multi-function vacuum generator and the intermediate modules with the desired capacities, already assembled, or you can assemble one or more intermediate modules to the GVMM generator that has already been installed on the machine, without having to make particular modifications. GVMM vacuum generators are composed of an anodised aluminium mono-block with lid, inside of which the silenced multiple ejectors are installed and the vacuum chamber and the compressed air supply connection are contained.
The following are instead installed on the outside:
- A micro solenoid valve for supplying compressed air to the generator.
- A micro solenoid valve for blowing the exhaust compressed air.
- An adjustable flow regulator for dosing the exhaust air.
- A digital vacuum switch provided with display and commutation LEDs, for managing the compressed air supply and for signalling the safety cycle start-up.
- An anodised aluminium or transparent Plexiglass manifold provided with vacuum connections with built-in suction filter, easy to inspect, and a check valve for maintaining the vacuum in case of electricity or compressed air failure.
By activating the compressed air power micro solenoid valve, the generator creates vacuum for use. As soon as the preset maximum value is reached, the digital vacuum switch acts on the electric coil of the micro solenoid valve and stops the air supply, reactivating it when the vacuum falls below the minimum level.Besides maintaining the level of vacuum within set safety values (hysteresis), this modulation allows for considerable compressed air savings.
A second signal from the vacuum switch (also adjustable and independent with respect to the first) can be used to start the cycle when the level of vacuum reached is suitable for use.

GVMM multi-function vacuum generators can be installed in any position and are suited for interconnecting vacuum gripping systems for handling sheet steel, glass, marble, ceramic, plastic, cardboard, wood, etc., and, in particular, for the industrial robotics sector which requires equipment with excellent performance and several independent vacuum units for controlling several applications but with reduced size and weight.
Multi-stage, multi-function and modular intermediate vacuum modules series MI - General description
Intermediate modules are non-independent multi-stage and multi-function vacuum generators to be assembled to the generators of the GVMM range.
Their thickness and weight are reduced to the maximum compared to their suction flow rate and they have been designed to be enclosed between the lid and the base of the GVMM vacuum generator and fixed with screws. The internal connections for the compressed air supply allow communication between them and the basic generator, with no need for external manifolds.
This way, each module becomes an independent vacuum unit that can control an entire vacuum system.
They can be ordered in the desired amount and flow rate, either already assembled onto the GVMM multi-function vacuum generator, or separately, to be assembled to the GVMM generator previously installed onto the machine. In this case, we suggest ordering a screw kit suitable for the number of modules to be assembled.
MI intermediate vacuum modules are made up of the same elements that compose GVMM generators, except for the lid. They operate and they are used as the GVMM multi-function vacuum generator onto which they are assembled.
GVMM multi-function vacuum generators can be assembled with one or more intermediate modules, thus forming a modular vacuum system, featuring a compact shape and reduced size and weight.
As a standard, up to 6 vacuum units can be assembled, but using threaded bars instead allows assembling even more.

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.
Product codes: PVR25 PVR50

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.

Working principle
The compressed air supply blown into a ring chamber concentric to the device, flows at a very high speed towards the centre of the main pipe, thus forming a cyclonic effect.
The latter creates a vacuum inside the device and leads a great volume of air towards its outlet.
Therefore, a variation of the air supply pressure will modify the level of vacuum and the amount of sucked air. Features
The special shape of the flow generators and their straight-flow working principle allow for the suctioning and handling of various nature products without interference. Vacuum Jets are in fact suitable for the handling of powders, granulated products, sawdust, corn, metal chips, liquid or dry food products, etc., or for extracting fumes, coolant mists, water or oil condensation, etc.
The absence of moving parts allows them to be used continuously, without developing heat.
They do not require electricity; therefore, they can 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.

Mini pneumatic pump sets are small independent vacuum-producing units, exclusively supplied with compressed air, with reduced size.
They are composed of:
- A small welded sheet steel tank
- A shut off valve to intercept compressed air
- A pressure regulator with filter and pressure gauge
- A compressed air vacuum generator
- A pneumatic drive valve for supplying the vacuum generator operated by the vacuum switch
- A pneumatic vacuum switch for adjusting the level of vacuum
- A vacuum gauge for reading the level of vacuum
- A manual valve for vacuum interception
- A suction filter with FC series paper cartridge
- A cock for condensation drainage from the tank
The level of vacuum, preset via the mini vacuum switch is automatically maintained in the tank.Mini pneumatic pump sets are suited for equipping fixed or mobile working units that require vacuum, such as:
- Trolleys with vacuum cups for fixing and transporting glass and crystals.
- Vacuum clamping systems for ski maintenance, marble drilling and processing, for polishing objects in pewter, copper, silver, etc.
- Hoists with vacuum cups for lifting television sets and household appliances in general, for glass installation in door and window frames, for feeding sheet metal into presses, etc.
The mini pneumatic pump sets do not require any electrical current but only compressed air at 4-6 bar pressure. Recommended in working environments where ignition sources could cause a fire hazard.

This mini pump set is set apart from the previously ones for the vacuum generator installed, as well as for the tank volume.
Vacuum generators of the series PVP... MDX ES are in fact equipped with an energy saving device which automatically maintains the preset level of vacuum inside the tank.
The other accessories installed, except the vacuum switch and the pneumatically driven valve for vacuum generator supply, are the same installed on DOP 06 and DOP 10. Their intended use is the same as the previously described mini pneumatic pump sets.

Pneumatic pump sets are self-contained vacuum production units, fed exclusively by compressed air.
They are composed of:
- A welded sheet steel tank
- A compressed air vacuum generator of the series PVP ... MDX ES, equipped with an energy saving device
- A vacuum gauge for reading the level of vacuum
- A manual valve for vacuum interception
- A suction filter with FC series paper cartridge
- A pressure regulator with filter and pressure gauge
- A shut off valve to intercept compressed air
- A cock for condensation drainage from the tank
The level of vacuum in the tank, previously set with the vacuum switch in the generator, is automatically maintained. The pneumatic pump sets are normally used to handle particularly heavy or valuable loads, as it allows vacuum cups to maintain grip for a certain period of time (varies according to tank capacity) even during unexpected absence of power. These pump sets are recommended for multi-point applications, to centralise vacuum. In both cases, use of the pump set is especially advantageous under the profile of energy savings as the generator only operates when a vacuum is required by the utility machine.
The pneumatic pump sets do not require any electrical current but only compressed air at 4-6 bar pressure. Recommended in working environments where ignition sources could cause a fire hazard.

The level of vacuum in the tank, previously set with the vacuum switch integrated in the pneumatic coaxial shutter supply valve, is fully automatically. The pneumatic pump sets are normally used to handle particularly heavy or valuable loads, as it allows vacuum cups to maintain grip for a certain period of time (varies according to tank capacity) even during unexpected absence of power. They are also recommended for centralising vacuums, for powering multiple utility machines. In both cases, use of the pump set is especially advantageous under the profile of energy savings as the generator only operates when a vacuum is required by the utility machine.
The pneumatic pump sets do not require any electrical energy but only compressed air at 4-6 bar pressure. Recommended in working environments where ignition sources could cause a fire hazard.
