Becker SV 5.300/1 5.5kW Side Channel Blower
The Becker SV 5.300/1 is a single-stage side channel blower delivering 325 m³/h nominal capacity at 50 Hz, with maximum relative vacuum of -350 mbar and maximum positive pressure of +430 mbar.
Powered by a 5.5kW motor, this SV5 configuration combines substantial airflow with particularly strong differential capability for a single-stage blower. Its +430 mbar maximum positive pressure makes it well suited to applications where air must be moved against significant system resistance, while -350 mbar relative vacuum provides strong suction capability.
The regenerative side channel principle generates vacuum or pressure without rubbing carbon vanes or oil-sealed compression. This provides an oil-free process-air path suitable for a broad range of industrial machinery and process applications.

High Differential Single-Stage SV 5.300/1 Performance
The Becker SV 5.300/1 combines 325 m³/h nominal airflow with a notably strong operating differential for a single-stage side channel blower. Maximum relative vacuum reaches -350 mbar, while maximum positive pressure extends to +430 mbar.
This gives the 5.5kW configuration a different performance emphasis from lower-powered blowers intended primarily to move large volumes of air at relatively small differential. The SV 5.300/1 can provide substantial airflow while also working against meaningful suction or discharge-side resistance.
On vacuum applications, its -350 mbar maximum relative vacuum provides useful capability for handling, extraction and industrial machine processes. On pressure duties, the +430 mbar maximum makes the blower particularly relevant where air must pass through restrictive pipework, process equipment or conveying systems.
The SV 5.300/1 uses regenerative side channel compression. Air entering the blower is accelerated by the rotating impeller and repeatedly circulated through the side channel. Energy is progressively transferred to the air as it travels around the casing, developing the required vacuum or positive-pressure differential.
The compression process is non-contact. There are no carbon vanes sliding against the compression chamber and no lubricating oil is required within the process-air path, providing continuous oil-free airflow for suitable industrial applications.
Becker SV 5.300/1 Technical Specification
The 5.5kW SV 5.300/1 has a nominal capacity of 325 m³/h at 50 Hz. Maximum relative vacuum is -350 mbar and maximum relative positive pressure is +430 mbar.
| Model | Stage | Nominal Capacity 50 Hz |
Maximum Vacuum | Maximum Pressure | Motor Power |
| SV 5.300/1 | Single Stage | 325 m³/h | -350 mbar | +430 mbar | 5.5kW |
The nominal 325 m³/h airflow and maximum vacuum or pressure values represent different operating points. As system differential increases, the volume of air available from a side channel blower changes according to its performance characteristic.
For a new installation, the required airflow should therefore be considered at the actual working vacuum or positive pressure rather than selecting from nominal capacity alone. Pipework diameter and length, bends, filters, valves, silencers and restrictions within the process can all contribute to the total system resistance.
SV 5.300/1 Performance Characteristics
325 m³/h Airflow
Substantial nominal capacity for industrial machinery, process-air systems and applications requiring continuous air movement.
-350 mbar Vacuum
Strong relative vacuum capability for demanding suction, handling and industrial process applications.
+430 mbar Pressure
High positive-pressure differential for systems where airflow must overcome significant discharge-side resistance.
Single-Stage Design
A regenerative single-stage configuration combining useful airflow with strong vacuum and pressure performance.
5.5kW Motor
The SV 5.300/1 specification covered on this page is powered by a 5.5kW electric motor at 50 Hz.
Oil-Free Air Path
Regenerative compression requires neither rubbing carbon vanes nor lubricating oil within the process-air chamber.
Applications for the Becker SV 5.300/1
The combination of 325 m³/h nominal airflow and strong single-stage differential gives the SV 5.300/1 scope for demanding industrial duties on either the vacuum or positive-pressure side of a system.
› Pneumatic conveying
› Vacuum handling and lifting
› Packaging machinery
› Printing and paper equipment
› Drying and process air
› Aeration systems
› Industrial extraction
› General mechanical engineering
For a new application, the required working point should be established from both airflow and differential. The +430 mbar maximum pressure figure can make this model particularly relevant where the system presents substantial resistance, but the complete duty should be considered before selection.
Replacing an Existing Becker SV 5.300/1
Side channel blowers are frequently incorporated into production machinery for long periods, and the exact operating requirement may not be obvious from the basic machine information. When replacing an SV 5.300/1, the complete blower and motor specification should therefore be checked.
Send Vacuum Pumps UK photographs of the complete unit together with clear images of the Becker identification plate and motor nameplate. Photographs showing the inlet, discharge and surrounding installation can also help us understand how the blower is being used.
Where possible, tell us whether the blower operates on vacuum or positive pressure and describe its function within the machine or process. Known operating vacuum, pressure or airflow information should also be included.
This allows the replacement requirement to be considered against the actual duty rather than relying solely on nominal airflow or the basic model designation.
Accessories and System Protection
With up to -350 mbar relative vacuum or +430 mbar positive pressure available, suitable filtration, relief protection and correctly sized pipework are important. Excessive system restriction can increase differential and operating temperature, while contamination can adversely affect blower condition.
Inlet Filtration
Correctly selected filtration helps prevent airborne contamination entering the blower without creating unnecessary suction restriction.
Relief Protection
Vacuum or pressure relief can protect the blower if system differential rises beyond the intended operating condition.
Silencers
Suitable inlet and discharge silencers can help manage transmitted air noise within industrial blower installations.
Pipework & Connections
Correct pipe sizing, suitable fittings and flexible connections help minimise avoidable restriction and system pressure loss.
SV 5.300/1 Service and Repair
The regenerative compression principle does not rely on rubbing carbon vanes, but the blower still contains bearings, an electric motor and other mechanical components that can deteriorate during extended industrial service.
Changes in noise, vibration or operating temperature should be investigated. A reduction in vacuum, pressure or airflow does not necessarily indicate an internal blower fault; blocked filters, leakage, restricted pipework or changes elsewhere in the process can produce similar symptoms.
Vacuum Pumps UK can inspect Becker side channel blowers in our workshop, investigate mechanical and performance problems and advise on servicing, repair or replacement.
