Vacuum pumps for dental suction systems
Consistent suction performance for modern dental suction systems
Whether in a single dental practice, a group practice or a clinic with multiple treatment rooms, the reliable performance of a dental suction system depends heavily on the vacuum generation technology used. One particular challenge is the simultaneous operation of multiple suction units. In these situations, the system must provide a consistent airflow, withstand frequent start-stop cycles and remain reliable and ready for use at all times.
Manufacturers of dental suction systems and dental units face a wide range of requirements. Alongside dependable suction performance, factors such as energy efficiency, noise levels, space requirements and maintenance effort play an important role. At the same time, systems must be flexible enough to accommodate different installation sizes and usage scenarios.
Drawing on decades of experience, Becker develops and manufactures high-performance vacuum solutions for dental applications. Our side channel blowers and radial blowers in particular, along with a range of other vacuum technologies, help equipment manufacturers and system integrators develop modern dry and wet dental suction systems.

Typical applications of vacuum pumps in dental suction systems:
- Dental practices
- Central dental suction systems
- Group practices
- Dental clinics
- Dry dental suction systems
- Wetdental suction systems
- Integrated suction solutions for dental equipment
The requirements for modern dental suction systems
In a dental practice, suction must be reliable at all times. At the same time, demand can vary considerably depending on how busy the practice is.
In larger practices, dental centres and clinics, multiple treatment units often operate simultaneously. The vacuum generation system must therefore be designed to provide sufficient suction capacity even during peak demand. Key requirements for vacuum generation include:

In centralised systems in particular, the correct sizing of the vacuum generation system is a key factor in the overall performance of the dental suction system, while also contributing to ease of use and patient comfort.
Dry or wet dental suction systems?
When planning a dental suction system, one of the first decisions is the choice of system concept.
In general, a distinction is made between dry and wet suction systems. Both approaches are based on different technical principles and place different requirements on the vacuum generation system.
Dry suction systems
In dry systems, the separation of air and liquid takes place directly at the treatment unit or within an upstream separation system. As a result, the vacuum generation system primarily handles air, making operation particularly efficient. Advantages of dry systems:
- High energy efficiency
- Reduced contact with media
- Flexible system design
Wet suction systems
In wet systems, air and liquid are transported together to a central separation unit. This design is widely used in existing installations and comes with its own requirements for pipework design and system sizing.
The choice of the most suitable vacuum technology therefore always depends on the system architecture and operating conditions of the individual installation.
Why side channel blowers are particularly well suited to dental suction systems
Side channel blowers are used in many modern dental suction systems. They offer exactly the characteristics required for dental applications that demand high air flow rates at moderate vacuum levels.
Unlike many other vacuum technologies, side channel blowers operate oil-free and contact-free. There is no mechanical contact between rotating and stationary components within the compression chamber. This significantly reduces wear, allowing for long maintenance intervals and helping to minimise servicing costs.
For central dental suction systems with multiple treatment chairs connected to a single installation, high operational reliability and minimal downtime are important advantages and can be a significant competitive differentiator.
Advantages of side channel blowers in dental applications:
| ✓ | Oil-free and contact-free operation | ✓ | Low-maintenance, low-wear performance | |
| ✓ | High air flow rates | ✓ | Reliable continuous operation | |
| ✓ | Compact design | ✓ | Wide range of accessory options | |
| ✓ | High flow rates of up to 1,250 m³/h | ✓ | Low-noise operation | |
| ✓ | Energy-efficient performance | ✓ | Flexible integration into new and existing installations |
These characteristics make side channel blowers suitable for a wide variety of system configurations in dental practices and dental clinics.
Depending on the system design, side channel blowers can supply multiple treatment stations simultaneously without compromising the required suction performance during concurrent operation. In addition, versions with VARIAIR for demand-based performance control and GAS-TIGHT for applications requiring gas-tight operation are available.

Optimising dental suction systems: suction power, noise reduction and energy efficiency
A common challenge in dental suction systems is a noticeable drop in suction performance when several treatment chairs are used at the same time. In many cases, the vacuum source is initially assumed to be the cause. However, the root issue often lies in the overall system design.
Possible causes include:
- Insufficient airflow capacity
- Incorrectly sized pipework
- Unfavourable pipe routing
- Clogged filters
- Leaks within the system
- Insufficient performance reserves during peak demand
A holistic assessment of the vacuum generation system, pipe network and actual usage patterns helps identify the most suitable vacuum solution for your specific dental suction system.
In centralised dental suction systems, blowers and vacuum pumps are often installed in dedicated plant rooms or basement areas. Even with this type of arrangement, however, vibration and noise can still be transmitted through the building and remain noticeable in treatment rooms.
For manufacturers and system planners, low noise and vibration levels are therefore important considerations when designing the overall system.
Possible measures to reduce noise and vibration include:
- Vibration-isolated mounting
- The use of high-performance silencers
- Optimised pipework design
- Adjustment of speed control settings
- Demand-driven performance control
When these factors are considered during the planning stage, they can have a significant impact on user satisfaction later on. With its range of vacuum pumps and a carefully considered system-wide approach, Becker helps ensure the right solution is selected for each application.
As dental suction systems are often operated for many hours each day, energy consumption is becoming an increasingly important consideration.
This is particularly true for larger dental groups and clinics, where optimising vacuum generation can have a direct impact on operating costs.
Modern side channel blowers equipped with VARIAIR demand-driven control can be adjusted to match actual system requirements more closely, helping to avoid unnecessary energy consumption.
As an alternative, Becker radial blowers offer significantly higher efficiency thanks to their operating principle, resulting in lower operating costs per m³/h. These units can also be equipped with VARIAIR to provide demand-based performance control.

Frequently asked questions about vacuum pumps for dental suction systems
For applications with multiple treatment chairs, side channel blowers are often used because they can deliver high flow rates while requiring minimal maintenance. The most suitable solution depends on factors such as the system design, the number of treatment chairs and the operating conditions.
The key factors are the number of treatment chairs, the expected simultaneity factor, the pipework layout and the required suction performance at each workstation.
Possible causes include an undersized blower, pressure losses within the pipework, clogged filters or insufficient performance reserves within the overall system design.
Side channel blowers deliver high airflow rates, operate without oil and without internal contact between moving components, and are well suited to continuous operation with minimal wear.
Yes. The specific system design depends on the application requirements and the overall suction system concept. Side channel blowers can be used in both wet and dry dental suction systems when they are properly matched to the operating conditions and performance requirements.
