Vacuum components

What are the values of maximum overpressure (e.g. with blow-off impulse) for which the components (filter, vacuum valves, etc.) have been designed?


There are different values for each component. These are listed in our Product Section in most cases.

When do you use oil-free or oil-lubricated vacuum pumps?


Oil-lubricated vacuum pumps achieve a very high level of the final vacuum of 99.9% (= -999.5 mbar max.), generate high volume flow and can sometimes be used even in moist or humid ambient conditions. Moreover, they are suitable for continuous operation.

Oil-free or non-lubricated vacuum pumps generate high volume flow and a high level of vacuum (up to -880 mbar max.). They are particularly suitable for dry air, when the vacuum level changes frequently, and also for constant low-vibration extraction.

When is a side channel blower suitable?


Side channel blowers generate a high volume flow with a low to medium level of vacuum. They are particularly suitable for handling porous materials (e.g. paperboard containers, insulating materials or similar) and compensate for leakages with their high suction power. Side channel blowers can also be used as extractors for particles that are not too coarse or abrasive.

At what values of pressure can vacuum pumps be operated in continuous mode?


Most of the oil-lubricated vacuum pumps can be used in continuous mode of operation only under full load. For this purpose, a vacuum level of at least 99.8 % is necessary.

What are the significant differences between an ejector and a vacuum pump?


Vacuum pumps (a) are vacuum generators driven by a motor, in which the vacuum is generated from suctioned ambient air either in accordance with the displacement principle (= rotary vane pumps) or the impulse principle (= side channel blowers).

Ejectors (b) are vacuum generators, without a motor, that generate the vacuum from compressed air using the Venturi principle.

The FIPA product range covers ejectors having air consumption from ~ 10 l/min up to a maximum of about 800 l/min as well as vacuum pumps from ~ 2 m3/h. up to ~ 310 m3/h.

When do you use a vacuum pump and when do you opt for an ejector to generate a vacuum?


Rotary vane vacuum pumps are primarily used in applications demanding a high level of the final vacuum with a large volume flow at the same time. Areas of application are, for example, vacuum supply for centralised vacuum systems or for handling sealed work-pieces.

Their performance range: Final vacuum up to ~ - 999.5 mbar, volume flow ~ 2 m3/hr. up to about 300 m3/h.

Side channel blowers offer a very high volume flow with a low to medium level of vacuum: Performance range: Final vacuum up to ~ -300 bar, volume flow up to 310 m3/h.

Their application areas: Handling of porous products or products having a high degree of leakage, pneumatic extraction or evacuation of particles that are not too coarse or abrasive, for example, extraction of wood dust in the timber processing industry

Ejectors provide a high level of final vacuum (~ -900 mbar) with low to medium volume flows at the same time (10 l/min. up to around 800 l/min.). They can be mounted directly in the suction line or on the vacuum cups.

Their application areas: targeted vacuum supply directly at the material to be handled, e.g. supply to vacuum cup units in a packaging machine. They represent an economic alternative to vacuum pumps, particularly for smaller quantities of suctioned air. Over and above this, FIPA ejectors are practically maintenance-free.

Which ejector do you use and when?


In-line and mini ejectors:

These types of vacuum generators are single-chamber ejectors having a vacuum nozzle.

They are installed either directly in the hose line or directly at the vacuum cup or solenoid valves. Their air consumption values range from ~ 10 l/min. up to about 100 l/min.

Products with expandable options are also available (e.g. EMI models: Blow-off feature for short cycle times, vacuum switch connection and silencer options).

Compact ejectors:

These include the single-chamber ejectors of the models EKP, EKPP and EMM, which provide add-on features such as vacuum and blow-off control.

They are practically maintenance-free as a result of the dirt-proof design that does not use any filter. Moreover, the intelligent pressure control saves up to 50 % of compressed air or energy costs compared to other models available in the market without having to make any compromises. The EMM model is suitable for block assembly

Multi-chamber ejectors:

Multi-chamber ejectors have several ejector nozzles connected one after another. As a result, they need up to 3.5 times less compressed air compared to single-chamber ejectors.

They provide an economical alternative particularly for high values of air consumption and are used for large volume flows and high vacuum levels.

They are used for handling air-permeable and porous materials (e.g. paperboard containers, wooden fiber boards and insulating materials) having extremely high air requirement.

Heavy-duty ejectors:

Heavy-duty ejectors are the robust vacuum generators for harsh working conditions. They are insensitive to fluctuations in the compressed air network (3-6 bar). Their square design facilitates space-conserving installation of ejector blocks.

Partially available with the blow-off feature, with air consumption values up to about 100 l/min.

What is the service life of the FIPA vacuum pumps?


Since the service life of a vacuum pump depends on the application to a large extent, it is not possible to make any blanket or across-the-board statement in this regard.

When do you use vacuum grippers?


Foam vacuum grippers can be used in almost all automated handling processes, such as, for example, stacking and unstacking pallets, separating and sorting. They are suitable particularly when the gripping position is not fixed or the quantum of material varies (you grip either a piece or an entire layer of the product).

In the process, gripping is independent of the surface, porosity, size or weight of the product.

What are the significant differences between directly controlled vacuum valves and those supported by compressed air?


Directly controlled vacuum valves

When using a solenoid to control the valve, the valve flap is operated directly and a pneumatic line is not necessary. Versions with the switching functions NO (normally open) and NC (normally closed) are available separately.

Valves supported by compressed air

These valves are used in applications that require short cycle times and correspondingly fast switching operations. The valve function is supported by controlled compressed air.

The switching functions, NO and NC, can be realized with the same valve, since the vacuum supply and blow-off / bleeding or vent connections can be interchanged. It is not necessary to have a pneumatic line for these vacuum valves.

What is a Bernoulli vacuum cup?


A Bernoulli vacuum cup generates a vacuum based on the Bernoulli principle from compressed air and thus facilitates low-contact and torsion-resistant transport of sensitive products.

Extremely thin, air-permeable and sensitive work-pieces (e.g. in the photovoltaic and semiconductor industry - wafer) can be handled in this manner.

When do you use vacuum tanks and how large should the tank be?


Vacuum tanks are used whenever compressed air, vacuum or non-corrosive liquids need to be stored. They ensure efficient and energy-conserving utilization of compressed air and vacuum.

Vacuum tanks are particularly suitable when the compressed air or vacuum networks have highly fluctuating consumption patterns.

The size of the vacuum tank depends on the requirement of your application. We would be pleased to assist you with the selection, if you get in touch with us: +49 89 962489-0
