Becker SV7.190/2 2.2kW Side Channel Blower
The Becker SV7.190/2 is a two-stage side channel blower with 90 m³/h nominal capacity and balanced -330 mbar vacuum / +330 mbar pressure performance.
Driven by a 2.2kW motor at 50 Hz, this older Becker configuration is suited to applications where relatively modest airflow must be maintained against a useful vacuum or positive-pressure differential.
Its regenerative, non-contact compression system provides oil-free process air without sliding vanes operating within the compression chamber.
Vacuum Pumps UK can assist with Becker SV7 blower identification, supply and technical support.

Balanced Vacuum and Pressure Capability
One of the distinguishing characteristics of the SV7.190/2 specification is its balanced differential performance. Maximum relative vacuum is -330 mbar and maximum relative positive pressure is +330 mbar, giving the blower similar capability on either side of atmospheric pressure.
Its nominal 90 m³/h capacity places the emphasis on moderate air volume rather than the much higher flows associated with larger side channel blowers. This can make the configuration relevant to machinery where the process requires a controlled supply or extraction of air while still encountering appreciable system resistance.
The two-stage arrangement is central to this performance. Instead of passing through a single regenerative section, the air is acted upon through successive side channel stages, enabling additional differential to be developed.
There are no sliding vanes within the compression chamber and no oil is required to lubricate the process-air compression mechanism. This makes side channel technology useful in industrial applications where clean, continuous air movement is required.
As with any regenerative blower, the actual operating airflow depends on system differential. The 90 m³/h figure is therefore a nominal capacity rather than an indication that this airflow is maintained at the maximum vacuum or pressure limit.
SV7.190/2 50 Hz Performance Data
Our technical information lists the following performance for the Becker SV7.190/2:
| Model | Stage | Nominal Capacity | Maximum Vacuum | Maximum Pressure | Motor Power |
| SV7.190/2 | Two Stage | 90 m³/h | -330 mbar | +330 mbar | 2.2kW |
Key Characteristics of the SV7.190/2
90 m³/h Airflow
A moderate nominal air capacity suited to smaller process and machinery requirements.
-330 mbar Vacuum
Useful vacuum differential for suction, handling and extraction applications.
+330 mbar Pressure
Matching positive-pressure capability for blowing and process-air duties.
Double-Stage Operation
Two regenerative sections enable greater differential to be developed from the blower.
2.2kW Motor
The listed 50 Hz configuration uses a 2.2kW electric motor.
Non-Contact Impeller Principle
Regenerative compression does not depend upon sliding vanes to create the required differential.
Typical SV7.190/2 Applications
With 90 m³/h nominal capacity and balanced vacuum/pressure capability, the SV7.190/2 can suit machinery where relatively modest airflow is required against meaningful resistance.
› Packaging machinery
› Printing equipment
› Suction and extraction duties
› Drying and air-knife duties
› Waste water aeration
› General industrial machinery
Replacing an Older Becker SV7.190/2
An older blower should not automatically be replaced purely by matching nominal airflow. Connection arrangement, motor specification and the actual duty performed by the machine should also be considered.
For an existing SV7.190/2, send us photographs of the unit and clear images of the blower and motor identification plates. If possible, tell us what the blower is doing within the machine and whether it operates on vacuum or positive pressure.
This information helps when considering a suitable replacement and avoids relying upon model designation alone.
Filtration, Relief and System Components
The surrounding system can have a direct effect upon blower performance. Filters should be kept clean and correctly sized, while pipe restrictions and closed or partially obstructed valves can increase operating differential.
Air Filters
Correct inlet filtration helps protect the blower from process contamination.
Vacuum Relief Valves
Can protect the blower where inlet restriction may cause excessive vacuum differential.
Pressure Relief Valves
Can limit differential if a discharge line becomes more restrictive than intended.
Installation Parts
Silencers, connectors, valves and other components can be considered as part of the complete blower system.
Service and Repair of Becker SV7 Blowers
Older Becker side channel blowers can remain in service for long periods, making condition assessment useful when performance changes or mechanical noise develops.
Bearing wear, motor condition, contamination and system restriction are among the areas that may need investigation. A reduction in machine performance does not necessarily mean the blower itself is the only cause, so the operating system should also be considered.
Vacuum Pumps UK provides workshop service and repair support for industrial vacuum pumps and side channel blowers.
