Becker SV 7.380/1 4kW Side Channel Blower
The Becker SV 7.380/1 is a single-stage side channel blower delivering 360 m³/h nominal capacity at 50 Hz, with maximum relative vacuum of -225 mbar and maximum positive pressure of +275 mbar.
Powered by a 4kW motor, the SV 7.380/1 provides a balanced combination of industrial airflow and moderate operating differential. Its 360 m³/h capacity makes it suitable for machinery requiring a meaningful volume of air without moving into the considerably larger motor powers associated with higher-capacity blower installations.
Regenerative side channel compression generates vacuum or positive pressure without rubbing carbon vanes and without lubricating oil in the process-air chamber. This provides an oil-free air path for suitable handling, drying, cooling, extraction and general process-air applications.

Balanced Airflow for Industrial Machinery and Process Systems
The Becker SV 7.380/1 provides 360 m³/h nominal capacity from a 4kW motor, giving this single-stage blower a useful position between smaller machine-mounted units and the substantially higher-capacity blowers used on large process installations.
Maximum relative vacuum of -225 mbar provides suction capability for vacuum handling, extraction and machine processes. On positive-pressure duties, the SV 7.380/1 can develop up to +275 mbar relative pressure, allowing it to deliver air through pipework and equipment where moderate system resistance must be overcome.
This combination is particularly useful where the application requires a good volume of air but does not need the much higher differential associated with some more pressure-focused side channel blower configurations. Typical requirements can include moving, holding, drying, cooling or supplying process air within production machinery.
The SV 7.380/1 uses a rotating impeller and regenerative side channel to transfer energy to the air. Air entering the blower is repeatedly accelerated as it travels around the channel, progressively developing vacuum at the inlet and positive pressure at the discharge.
Because the compression process is non-contact, there are no carbon vanes rubbing against the compression chamber. No lubricating oil is required within the process-air path, providing clean, oil-free airflow for suitable industrial duties.
Becker SV 7.380/1 Technical Specification
The 4kW SV 7.380/1 provides 360 m³/h nominal capacity at 50 Hz. Maximum relative vacuum is -225 mbar and maximum relative positive pressure is +275 mbar.
| Model | Stage | Nominal Capacity 50 Hz |
Maximum Vacuum | Maximum Pressure | Motor Power |
| SV 7.380/1 | Single Stage | 360 m³/h | -225 mbar | +275 mbar | 4kW |
The 360 m³/h nominal capacity is not the airflow available at maximum vacuum or maximum pressure. These figures represent different operating conditions within the blower’s performance range.
As resistance in the system increases, the blower develops greater differential and the available airflow changes. Correct selection therefore requires the intended airflow to be considered at the actual working vacuum or positive pressure rather than comparing nominal capacities alone.
Filters, silencers, pipe length and diameter, bends, valves and restrictions within the machine all contribute to system resistance. These factors should be included when establishing the required operating point.
SV 7.380/1 Performance Characteristics
360 m³/h Airflow
Useful medium-capacity airflow for production machinery, handling equipment and industrial process-air installations.
-225 mbar Vacuum
Provides suction differential for vacuum handling, extraction and machine processes requiring a combination of airflow and vacuum.
+275 mbar Pressure
Useful positive-pressure capability for process air, drying, cooling and systems operating against moderate resistance.
Single-Stage Design
One regenerative compression stage provides a practical balance between air volume and vacuum or pressure differential.
4kW Motor
The 50 Hz SV 7.380/1 specification covered here uses a 4kW electric motor to provide its 360 m³/h nominal capacity.
Non-Contact Compression
Regenerative operation requires neither sliding carbon vanes nor lubricating oil within the process-air chamber.
Applications for the Becker SV 7.380/1
The combination of 360 m³/h airflow and moderate vacuum or pressure differential makes the SV 7.380/1 suitable for a broad range of industrial machine functions. It can be applied on either the suction or discharge side where its performance matches the required duty point.
› Vacuum handling and lifting
› Packaging and production machinery
› Printing and paper equipment
› Industrial extraction systems
› Drying and cooling processes
› Process-air supply
› Light pneumatic conveying
› General mechanical engineering
Actual suitability depends upon the airflow required at the intended vacuum or pressure. A process needing close to the blower’s nominal 360 m³/h capacity at low differential is a different duty from one requiring operation nearer its maximum vacuum or pressure.
Vacuum Pumps UK can assist with selection where the required airflow and differential are known, or help assess the operating requirement when replacing an existing blower within production machinery.
Replacing an Existing Becker SV 7.380/1
When a side channel blower is built into production machinery, matching the model number is only one part of establishing the replacement requirement. The operating duty, motor specification, pipework arrangement and function of the blower within the machine should also be considered.
Send Vacuum Pumps UK photographs showing the complete SV 7.380/1 together with clear images of the Becker identification plate and motor nameplate. Photographs of the inlet and discharge connections can help establish how the blower is configured within the system.
Tell us whether the blower is used on vacuum or positive pressure and describe what it does within the machine. Where available, include the normal operating vacuum or pressure, required airflow and any information about the process.
These details allow the replacement to be assessed against the actual requirement rather than assuming that nominal capacity alone determines suitability.
Accessories and System Protection
The performance of an SV 7.380/1 depends on the complete installation as well as the blower itself. Suitable filtration protects the blower, while appropriately sized pipework and accessories help prevent avoidable pressure losses and excessive operating differential.
Inlet Filtration
Correct filtration helps prevent airborne contamination reaching the blower while maintaining sufficient flow area for the required duty.
Relief Protection
Suitable vacuum or pressure relief can limit differential if filtration blocks, a valve closes or the process becomes more restrictive.
Silencers
Inlet or discharge silencers can help reduce transmitted air noise where this is required by the machine or installation.
Pipework & Connections
Correctly sized pipework, flexible connections and suitable fittings help minimise restriction and preserve available airflow.
SV 7.380/1 Service, Repair and Spare Parts
Regenerative compression avoids the rubbing carbon vanes used in dry-running rotary vane pumps, but the SV 7.380/1 still contains bearings, an electric motor and other mechanical components that are subject to wear during industrial operation.
Changes in noise, vibration or operating temperature can indicate a developing mechanical issue. Reduced suction, pressure or airflow should also lead to checks of the surrounding system, because dirty filtration, leakage, restricted pipework or changes to the process can alter performance without an internal blower failure.
