Becker SV5.250/1 2.2kW Side Channel Blower
The Becker SV5.250/1 is a single-stage side channel blower combining 230 m³/h nominal airflow with equally balanced vacuum and pressure capability.
At 50 Hz, the 2.2kW configuration provides maximum relative vacuum of -190 mbar and maximum positive pressure of +190 mbar. This symmetrical performance makes the SV5.250/1 particularly versatile where either suction or discharge pressure may be required.
The non-contact side channel principle produces continuous oil-free process airflow for industrial machinery, handling equipment and process-air systems.

Balanced Vacuum and Pressure Performance
The SV5.250/1 occupies a useful position within the Becker side channel blower range where a substantial volume of air is required without moving into the larger motor ratings. Its 230 m³/h nominal capacity provides considerably more process airflow than smaller blower sizes while retaining a 2.2kW motor.
A notable characteristic of this configuration is its balanced differential capability. Maximum relative vacuum is -190 mbar and maximum positive pressure is +190 mbar, allowing the blower to perform effectively on either the suction or discharge side of an industrial air system.
Side channel compression works by repeatedly accelerating air between the rotating impeller and the surrounding channel. Each pass transfers additional energy to the air until the required differential is developed.
The impeller operates without rubbing contact with the blower housing, and lubricating oil is not required within the process-air chamber. The SV5.250/1 can therefore provide continuous oil-free airflow for machinery and process applications.
Actual operating airflow will vary according to the resistance imposed by the installation. Pipe diameter, pipe length, filters, valves and process restrictions should all be considered when selecting a replacement blower or designing a new system.
Becker SV5.250/1 Technical Data
At 50 Hz, the SV5.250/1 provides a nominal capacity of 230 m³/h from its 2.2kW motor, with equal maximum relative vacuum and positive-pressure differentials of 190 mbar.

SV5.250/1 Performance and Design
230 m³/h Airflow
Provides a useful volume of process air for industrial machinery, handling equipment and conveying applications.
-190 mbar Vacuum
Suitable for suction duties requiring greater differential than lower-capacity side channel blowers.
+190 mbar Pressure
Matching positive-pressure capability allows the blower to serve blowing, aeration and process-air duties.
2.2kW Motor
Combines a relatively modest motor rating with 230 m³/h nominal blower capacity.
Oil-Free Process Air
No lubricating oil is required within the process-air chamber during normal blower operation.
Non-Contact Compression
The side channel principle generates airflow without relying on rubbing vanes within the compression chamber.
Typical SV5.250/1 Applications
The combination of 230 m³/h nominal airflow and balanced -190 / +190 mbar differential allows the SV5.250/1 to be considered for a broad range of industrial vacuum and pressure duties.
› Vacuum lifting and component handling
› Packaging and processing machinery
› Printing and paper equipment
› Sheet transport and separation
› Pneumatic conveying
› Drying and cooling systems
› Waste water aeration and blowing duties
› General industrial process air
SV5.250/1 Supply and Replacement
Vacuum Pumps UK can assist where an SV5.250/1 is required as a replacement for an existing Becker blower or where a side channel blower is being selected for a new application.
For replacement installations, the existing blower nameplate is particularly useful. The model, motor rating and electrical details can be checked together with information about the machinery on which the blower is installed.
Where the blower is being selected for a new system, both airflow and differential should be considered. A requirement for 230 m³/h at little resistance is very different from a requirement approaching the blower’s maximum vacuum or pressure differential.
Becker SV5.250/1 Blower Accessories
Filtration, relief valves and connection components can help protect the blower and allow the SV5.250/1 to be correctly integrated into the vacuum or pressure system.
Inlet Filtration
Filters help prevent airborne particles and process contamination from entering the blower air path.
Vacuum Regulation
Vacuum relief can limit excessive suction differential if system resistance becomes too high.
Pressure Protection
Pressure relief devices help protect the blower where it is operating on the positive-pressure side.
Installation Accessories
Silencers, flexible connections, non-return valves and pipework components can be selected to suit the installation.
Becker SV5.250/1 Service, Repair and Spare Parts
Side channel blowers have relatively straightforward routine maintenance requirements, but bearings, motors, filters and other components can deteriorate during extended industrial service. Reduced airflow, abnormal noise, increased temperature or changes in performance can indicate that inspection is required.
Vacuum Pumps UK can assist with fault diagnosis, servicing and workshop repair requirements for Becker SV side channel blowers.
Blower Service
Technical support and maintenance assistance for installed Becker side channel blowers.
Blower Repair
Workshop assessment of noisy, damaged or poorly performing Becker blowers and motors.
Spare Parts
Replacement filters and Becker spare parts are available through our sister company VacAir Superstore.
