Vacuum pumps for central vacuum supply

In a central vacuum supply, one pumping station generates the vacuum for many machines at once: according to Leybold, several machines are connected to one network with speed-controlled pumps; Becker describes a shared vacuum network instead of individual pumps that works on demand and outside production. Below you can see how the application works, what vacuum the manufacturers name and which of their series are intended for it ā€“ 285 models from 7 manufacturers.

In short

Central vacuum systems: the key facts

  • One networkAccording to Leybold, in a central vacuum system several machines are connected to one network with speed-controlled pumps. For packaging lines Becker describes a shared vacuum network instead of individual pumps, and for the wood industry vacuum that is generated centrally, on demand and outside production.
  • EnergyFor the wood industry, Becker names 30 to 50 % less energy with a payback period of 12 to 36 months, and for packaging lines up to 50 % less energy. For meat packaging, Atlas Copco names up to 50 % less energy and CO2, Leybold energy savings of often more than 50 % (Leybold figure).
  • Pressure and pumping speedFor the house vacuum in IC manufacturing, Atlas Copco names 100 to 400 mbar abs. and 2,000 to 8,000 mĀ³/h, in large fabs more than 12,000 mĀ³/h. For electronics manufacturing Leybold names a central vacuum below 100 mbar, Elmo Rietschle 380 to 1,140 mĀ³/h for the C-VLR 1000 VSD / HV+.
  • Pressure controlAtlas Copco names several lines with precise pressure control; Elmo Rietschle describes the claw vacuum pump as part of a central vacuum system with setpoint pressure control. Leybold names speed-controlled pumps, Becker demand-controlled generation with VARIAIR.

Operating principle

How it works: Central vacuum systems

The drawing shows the basic principle in section. The systems and pumps of the individual manufacturers differ in detail.

  1. GenerationThe pumping station generates the vacuum centrally in one place; Becker names generation outside production.
  2. DistributionThe ring main and buffer tank carry the vacuum to all consumers; according to Leybold, several machines are connected to one network.
  3. ControlThe control system maintains the setpoint pressure (Elmo Rietschle) and adapts the pumps to the demand via their speed (Leybold, Becker).

Vacuum and sizing

Central vacuum systems: how much vacuum is needed

What the manufacturers say about pressure, pumping speed and sizing.

Which vacuum

For the house vacuum in IC manufacturing, Atlas Copco names 100 to 400 mbar abs., Leybold a central vacuum below 100 mbar for electronics manufacturing. The pressure depends on the connected consumers.

Which pumping speed

Atlas Copco names 2,000 to 8,000 mĀ³/h for IC manufacturing and more than 12,000 mĀ³/h for large fabs. For the C-VLR 1000 VSD / HV+, Elmo Rietschle names 380 to 1,140 mĀ³/h (data sheet D1880). Otherwise the pumping speed follows from the number of consumers and their simultaneous demand.

What determines the sizing

The number of consumers and their simultaneous demand: Atlas Copco names several lines with precise pressure control, Becker demand-controlled generation. As benefits, Becker names 30 to 50 % less energy with a payback period of 12 to 36 months, Atlas Copco up to 50 % less energy and CO2, Leybold often more than 50 % (Leybold figure).

Pump types

Atlas Copco names oil-sealed, dry and liquid ring vacuum pumps with frequency control (VSD), Elmo Rietschle a claw vacuum pump with setpoint pressure control, Leybold speed-controlled pumps of the NOVADRY and CLAWVAC series (plus VACUBE). Becker names VACS with VARIAIR (KVT, KVX, VTLF, VXLF, BCV) and VADS, and for packaging lines U and U4 with RBP.

Frequently asked questions

Central vacuum systems: frequently asked questions

What is a central vacuum supply?

A pumping station generates the vacuum in one place and distributes it to many machines via a pipe network. According to Leybold, several machines are connected to one network with speed-controlled pumps; Becker describes a shared vacuum network instead of individual pumps. Atlas Copco names central vacuum systems for food, glass and brick production, Pfeiffer Vacuum as a shared vacuum supply for laboratories.

How does a central vacuum system work?

The pumping station evacuates all consumers via a ring main with a buffer tank. A control system maintains the setpoint pressure in the network ā€“ Elmo Rietschle describes the claw vacuum pump C-VLR 1000 VSD / HV+ as part of a central vacuum system with setpoint pressure control ā€“ and regulates the pumps via their speed (Leybold, Becker). For several lines, Atlas Copco names precise pressure control.

What are the advantages of central vacuum over individual pumps?

Becker names the shared vacuum network instead of individual pumps and generation outside production, centrally and on demand. Leybold names speed-controlled pumps to which several machines are connected, Atlas Copco precise pressure control for several lines. All three name lower energy demand as a result.

How much energy does a central vacuum system save?

For the wood industry, Becker names 30 to 50 % less energy with a payback period of 12 to 36 months, and for packaging lines up to 50 % less energy. For meat packaging, Atlas Copco names up to 50 % less energy and CO2. Leybold names energy savings of often more than 50 % (Leybold figure).

What vacuum does a central vacuum network need?

That depends on the consumers. For the house vacuum in IC manufacturing, Atlas Copco names 100 to 400 mbar abs., Leybold a central vacuum below 100 mbar for electronics manufacturing.

Which vacuum pump for a central vacuum system?

The manufacturers name different types: Atlas Copco oil-sealed, dry and liquid ring vacuum pumps with VSD as well as GHS VSD+, DZS, LRP VSD+, DHS VSD+ and AWL; Becker KVT, KVX, VTLF, VXLF, BCV, VADS and, for packaging lines, U, U4 and RBP; Busch R5, MINK, COBRA and PANDA/PUMA; Leybold NOVADRY and CLAWVAC; Elmo Rietschle the claw vacuum pump C-VLR; Edwards EDC and nEDC; Pfeiffer Vacuum ACP and DuoVane.

How is a central vacuum system controlled?

Via the pressure in the network: Elmo Rietschle names setpoint pressure control, Leybold speed-controlled pumps, Atlas Copco pumps with VSD and precise pressure control for several lines. Becker names demand-controlled generation with VARIAIR, in which the pumps deliver only as much as the consumers need at that moment.

When is a central vacuum supply worthwhile?

The manufacturers name it where many consumers need vacuum: several lines (Atlas Copco), several machines on one network (Leybold), packaging lines and the wood industry (Becker), laboratories (Pfeiffer Vacuum). For the wood industry, Becker names a payback period of 12 to 36 months.

What pumping speed does a central vacuum system need?

For the house vacuum in IC manufacturing, Atlas Copco names 2,000 to 8,000 mĀ³/h, and more than 12,000 mĀ³/h for large fabs. For the C-VLR 1000 VSD / HV+, Elmo Rietschle names 380 to 1,140 mĀ³/h (data sheet D1880). Otherwise the pumping speed follows from the number of consumers and their simultaneous demand.

In which industries do the manufacturers name central vacuum systems?

Atlas Copco for IC manufacturing, meat packaging and food, glass and brick production; Becker for the wood industry, packaging lines and dairies; Leybold for electronics manufacturing and general industry; Pfeiffer Vacuum for laboratories and research; Elmo Rietschle as a central air supply for printing and paper.
