Becker SV 5.490/1 7.5kW Side Channel Blower
The Becker SV 5.490/1 is a single-stage side channel blower delivering 472 m³/h nominal capacity at 50 Hz, with maximum relative vacuum of -300 mbar and maximum positive pressure of +410 mbar.
Powered by a 7.5kW motor, this SV5 configuration combines higher-volume airflow with substantial differential capability. The 472 m³/h nominal capacity makes it suitable for larger machinery and process systems, while +410 mbar maximum pressure and -300 mbar maximum relative vacuum provide useful operating range on either side of atmospheric pressure.
The blower generates airflow through regenerative side channel compression rather than rubbing carbon vanes or oil-sealed compression. This provides an oil-free process-air path for a broad range of industrial vacuum and positive-pressure applications.

Higher-Capacity SV 5.490/1 Vacuum and Pressure Performance
The Becker SV 5.490/1 provides 472 m³/h nominal capacity, giving this single-stage SV5 configuration substantial airflow for larger industrial machinery and process systems. Maximum relative vacuum is -300 mbar, while maximum positive pressure reaches +410 mbar.
This combination is useful where air volume cannot be considered independently from system resistance. The blower can move a significant quantity of air while also developing the differential needed to work through pipework, filtration, machine components and the process itself.
For suction applications, the -300 mbar maximum relative vacuum provides capability for vacuum handling, extraction and industrial machine processes. On the discharge side, the +410 mbar maximum positive pressure allows the SV 5.490/1 to serve applications requiring substantial pressure from a single-stage side channel blower.
Air enters the blower and is repeatedly accelerated by the rotating impeller as it travels through the side channel. This regenerative transfer of energy progressively develops the required pressure differential before the air reaches the outlet.
Because vacuum and pressure are generated without rubbing carbon vanes, the compression principle is non-contact. No lubricating oil is required within the process-air chamber, providing oil-free airflow for suitable industrial applications.
Becker SV 5.490/1 Technical Specification
The 7.5kW SV 5.490/1 has a nominal capacity of 472 m³/h at 50 Hz. Maximum relative vacuum is -300 mbar and maximum relative positive pressure is +410 mbar.
| Model | Stage | Nominal Capacity 50 Hz |
Maximum Vacuum | Maximum Pressure | Motor Power |
| SV 5.490/1 | Single Stage | 472 m³/h | -300 mbar | +410 mbar | 7.5kW |
The nominal capacity, maximum vacuum and maximum pressure figures should not be read as one simultaneous operating point. Actual airflow changes as the blower works against increasing vacuum or positive-pressure differential.
When selecting a blower for a new application, or assessing a replacement against a changed process, the required airflow should be considered at the intended working differential. Pipe diameter, pipe length, bends, filtration, valves and other restrictions all contribute to the resistance experienced by the blower.
SV 5.490/1 Performance Characteristics
472 m³/h Airflow
Higher nominal air volume for larger machinery, process-air systems and industrial applications with substantial airflow demand.
-300 mbar Vacuum
Strong suction performance for vacuum handling, extraction and industrial process applications.
+410 mbar Pressure
Substantial positive-pressure capability for conveying, process air and systems operating against significant resistance.
Single-Stage Design
Regenerative single-stage compression provides higher airflow together with useful vacuum and pressure differential.
7.5kW Motor
This SV 5.490/1 specification is powered by a 7.5kW electric motor at 50 Hz.
Oil-Free Compression
Regenerative operation requires no carbon vanes or lubricating oil within the process-air chamber.
Applications for the Becker SV 5.490/1
The SV 5.490/1 is particularly relevant to applications requiring greater air volume while retaining a substantial operating differential. It can be applied on either the vacuum or positive-pressure side of suitable industrial systems.
› Pneumatic conveying
› Vacuum handling and lifting
› Packaging machinery
› Printing and paper machinery
› Drying and process-air systems
› Aeration applications
› Industrial extraction
› General production machinery
The suitability of the SV 5.490/1 for a particular machine should be assessed from the required airflow at the actual working vacuum or pressure. The complete system resistance and operating conditions should also be considered when selecting the blower.
Replacing an Existing Becker SV 5.490/1
When an SV 5.490/1 forms part of production machinery, the correct replacement requirement should be established from the installed blower and its actual duty rather than nominal airflow alone.
Send Vacuum Pumps UK photographs of the complete blower together with clear images of the Becker identification plate and motor nameplate. Photographs of the inlet and discharge arrangement can also provide useful information about the installation.
Tell us whether the blower operates on vacuum or positive pressure and, where possible, describe the process or machine function it serves. If operating vacuum, pressure or airflow figures are known, include these with your enquiry.
These details allow us to assess the blower requirement against the application and help identify an appropriate replacement specification.
Accessories and System Protection
At 472 m³/h, unnecessary restriction in filtration or undersized pipework can have a significant effect on system performance. Suitable accessories should protect the blower while allowing the required airflow to move through the installation efficiently.
Inlet Filtration
Correct filtration helps prevent contamination entering the blower while maintaining sufficient flow area for the application.
Relief Protection
Vacuum or pressure relief can help 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 higher-flow blower installations.
Pipework & Connections
Appropriately sized pipework, fittings and flexible connections help reduce avoidable pressure loss and restriction.
SV 5.490/1 Service and Repair
The regenerative compression principle avoids rubbing carbon vanes, but bearings, the motor and other mechanical components remain subject to wear during extended industrial operation.
Increasing noise, vibration or operating temperature should be investigated. If airflow or machine performance has deteriorated, the complete system should also be checked because blocked filtration, pipework restriction, leakage or changes to the process can produce similar symptoms.
