Vacuum systems are responsible for dewatering of the paper web in the former section and for sheet transfer and felt conditioning in the press section.The vacuum system consists of the suction elements at the paper machine, the vacuum control loops, vacuum piping, water separation system, vacuum generators and exhaust line with silencer. When designing an xVac vacuum system, the experienced Voith experts ensure that the vacuum requirement of the paper machine is met as well as the specific demands and objectives of each customer – such as budget, energy requirement, flexibility and robustness. Other special conditions, like availability of space and water or ambient temperature, must also be taken into account.
As an independent partner, Voith advises the customer in choosing the most suitable vacuum system for his paper machine. After the choice is made, we support you with the design, supply and installation of the system. We work together with all industry-proven suppliers of vacuum generators and find the perfect fit for every application. Based on more than 80 years of experience, we combine your specific demands with the requirements of your paper machine and the characteristics of the different vacuum generators in an optimal way. In doing so, we keep the balance between investment and operating costs of your xVac vacuum system in line with your objectives.
Your benefits with xVac vacuum systems by Voith
- Experienced partner in designing and supplying vacuum systems
- Independent partner for the selection of the most suitable vacuum components
- Selection of well-proven equipment for highest runability
- Perfect match of paper machine and overall vacuum system including all involved components
- Responsibility in one hand with Voith as full-line supplier

Water ring vacuum pumps
Water ring vacuum pumps provide an operating vacuum range from 20 to 90 kPa.
Vacuum blowers provide an operating vacuum range from 25 to 75 kPa.
Low vacuum fans
Low vacuum fans are perfectly designed to cover the vacuum requirements of the first suction boxes in the former section. A balanced combination of low vacuum fans with vacuum blowers or water ring vacuum pumps results in higher energy efficiency and lower installation costs.
Low vacuum fans provide an operating vacuum range from 5 to 25 kPa.
Special Service: xVac vacuum audits
In a xVac vacuum audit conducted by Voith, you benefit from our extensive expertise, long-term experience and supplier neutrality.
The steam and condensate system supplies the individual heating groups and the included drying cylinders with the amount of steam required for drying the paper. The distribution of steam to the heating groups is controlled by the Quality Control System (QCS) and the heating curves of the heating groups. In addition, the steam and condensate system ensures that the condensate produced is reliably discharged from the cylinders. Through this system, other units can also be supplied with steam.
Based on its long-term expertise in papermaking, Voith designs, develops and installs safe and reliable xSteam solutions, including steam and condensate systems. Our experts will support you in choosing the ideal system for your machine, taking into account your individual requirements. As a result, you can optimize your paper production and reduce operating costs.
Your benefits with xSteam steam and condensate systems by Voith
- The best drying process for your product
- Energy-efficient technology
- Advanced drying concepts
- Improved dryer control concept
Energy-efficient cascade systems are appropriate for the production of all types of paper and are easy to maintain.
The steam and condensate mixture from a heating group is transferred to a separator and subdivided there. The condensate produced is fed to the boiler house via a condensate collector. The resulting flash steam is adjusted by a thermocompressor to the steam pressure of the heating group, so that it is ready for paper drying again.
Thermocompressor systems are suited best for the production of board and packaging papers but can be used for all types of paper.
xSteam TopDry reduces soiling and sticking due to surface drying on the first drying cylinders. This results in better runability.
The xSteam Pro also enables savings in cooling water, resulting in lower operating costs. The system is highly accepted due to the substantial savings of steam and cooling water, as well as the low investment costs.
- Steam savings, up to z 9.6u00 t/a
- Savings in cooling water, up to 20,800 m³/a
- ROI < 1.5 years
