Becker SV5.1050/2 11kW Side Channel Blower
The Becker SV5.1050/2 is a large two-stage regenerative blower providing 530 m³/h nominal capacity from an 11kW motor, combining substantial airflow with high vacuum and pressure capability.
At 50 Hz, the SV5.1050/2 reaches a maximum relative vacuum of -480 mbar and maximum positive pressure of +500 mbar. This combination makes it particularly relevant where a larger industrial process requires significant air volume while also operating against a considerable system differential.
Its non-contact side channel compression principle provides an oil-free process-air path without the rotor vanes associated with rotary vane pumps, reducing the need for more regular servicing and maintenance.

High Airflow for Demanding Two-Stage Duties
The SV5.1050/2 sits at the high-capacity end of the older Becker SV5 two-stage models in our technical reference information. Its 530 m³/h nominal capacity is accompanied by a maximum relative vacuum of -480 mbar and maximum positive pressure of +500 mbar.
That performance profile is significant because larger industrial systems can require both air volume and differential. Moving a useful volume of air through long pipe runs, filters, process equipment or conveying systems creates resistance, and the blower must be selected around the resulting operating point rather than airflow alone.
The SV5.1050/2 uses two regenerative compression stages. Air entering the blower is repeatedly accelerated by the impeller and returned through the side channel, progressively increasing its energy before continuing through the second stage. This allows considerably greater vacuum or pressure differential than would normally be associated with a simple low-pressure air mover.
Its -480 mbar maximum relative vacuum also gives this model substantial capability on the suction side, while the +500 mbar maximum pressure makes it suitable for consideration in demanding positive-pressure systems.
The process-air chamber does not require lubricating oil and the regenerative principle eliminates rubbing carbon vanes from the compression mechanism.
Becker SV5.1050/2 Technical Specification
The 11kW SV5.1050/2 provides 530 m³/h nominal capacity at 50 Hz. Maximum relative vacuum is -480 mbar and maximum relative positive pressure is +500 mbar.
| Model | Stage | Nominal Capacity | Maximum Vacuum | Maximum Pressure | Motor Power |
| SV5.1050/2 | Two Stage | 530 m³/h | -480 mbar | +500 mbar | 11kW |
For system selection, the nominal capacity and maximum differential figures should not be treated as simultaneous operating values. The available airflow varies according to the actual vacuum or pressure differential imposed by the installation.
SV5.1050/2 Performance Characteristics
530 m³/h Airflow
The higher nominal capacity makes this model relevant to larger industrial systems requiring substantial air movement.
-480 mbar Vacuum
Considerable suction capability for higher-differential vacuum handling and process applications.
+500 mbar Pressure
Strong discharge capability for applications where process and pipework resistance create substantial back pressure.
Two Compression Stages
Successive regenerative stages enable the SV5.1050/2 to develop its high vacuum and pressure differential.
11kW Motor
Provides the drive power required for this combination of higher air volume and demanding differential performance.
Oil-Free Air Path
Regenerative compression avoids the need for lubricating oil within the process-air chamber.
Where the SV5.1050/2 Can Be Used
The combination of 530 m³/h nominal capacity and high differential capability makes the SV5.1050/2 particularly relevant to larger machinery and process installations. The exact suitability depends upon the required airflow at the intended operating pressure or vacuum.

› Large drying systems
› Process-air supply

› Packaging and production equipment
› General industrial engineering
Identifying or Replacing a Becker SV5.1050/2
Older side channel blowers frequently remain installed on machinery long after the original equipment was commissioned. When an SV5.1050/2 requires replacement, it is useful to identify the complete configuration rather than relying only upon the basic model designation.
Send Vacuum Pumps UK photographs of the complete blower, the Becker identification plate and the motor nameplate. Details of whether the unit is being used for vacuum or pressure, together with any known process requirements, are also useful.
For new applications, we can consider required airflow, vacuum or discharge pressure, duty cycle and the resistance introduced by pipework and process equipment.
System Accessories for the SV5.1050/2
A 530 m³/h blower requires appropriately sized system components. Undersized pipework, restrictive filtration or unsuitable valves can introduce unnecessary differential, reduce available airflow and increase operating temperature.
Inlet Filters
Protect the blower from airborne contamination while maintaining adequate flow capacity for the installation.
Relief Valves
Vacuum or pressure relief can protect the blower when changing system conditions create excessive differential.
Silencers
Suitable inlet or discharge silencers can form part of a correctly designed blower installation.
Connections & Valves
Pipe diameter, flexible connectors and valve sizing should reflect the higher airflow of the SV5.1050/2.
SV5.1050/2 Service, Fault Diagnosis and Repair
Although regenerative blowers use non-contact compression, their bearings, motor and associated components remain subject to wear. System condition is equally important because restricted airflow or excessive differential can increase temperature and load.
A change in noise, vibration, temperature, airflow or process performance can therefore justify investigation of both the blower and the installation around it.
Vacuum Pumps UK can inspect and assess Becker side channel blowers in our workshop and assist with servicing, fault diagnosis and repair.
