Becker SV 700/1 5.5 kW Side Channel Blower
The Becker SV 700/1 5.5 kW is a high-volume single-stage side channel blower delivering 750 m³/h nominal airflow at 50 Hz for industrial vacuum and positive-pressure applications.
Maximum relative vacuum is -200 mbar and maximum positive pressure is +185 mbar at 50 Hz. At 60 Hz the 6.6 kW motor increases nominal airflow to 900 m³/h, with maximum relative vacuum of -170 mbar and maximum pressure of +150 mbar.
The 5.5 kW configuration is particularly relevant where the installation requires the considerable airflow capacity of the SV 700/1 but does not need the greater differential available from the 7.5 kW or 11 kW versions.

High Airflow with Moderate Operating Differential
The SV 700/1 5.5 kW provides a useful combination of substantial air volume and moderate vacuum or pressure capability. Its nominal 750 m³/h capacity at 50 Hz allows a large quantity of air to be moved without automatically requiring the greater motor power of the other SV 700/1 configurations.
This distinction is important when selecting a side channel blower. The three motor versions share the same nominal 50 Hz airflow, but their permissible operating differentials are significantly different. A larger motor should therefore not be selected simply on the assumption that it will provide more free airflow.
For applications operating within the -200 mbar vacuum or +185 mbar pressure capability of this version, the 5.5 kW configuration can provide the required SV 700/1 airflow while avoiding unnecessary motor sizing.
Air movement is produced by a rotating impeller accelerating the gas through the side channel. Because the compression mechanism is non-contact and does not require oil within the air chamber, the blower provides clean airflow with relatively straightforward routine maintenance.
Correct selection still depends on the actual operating point. Pipework, filters, valves, silencers and restrictions within the connected process influence the pressure differential and airflow that the blower must deliver in service.
Becker SV 700/1 5.5 kW Technical Specifications
At 60 Hz the corresponding 6.6 kW motor increases nominal volume flow from 750 to 900 m³/h. Maximum relative vacuum is -170 mbar and maximum positive pressure is +150 mbar.
| Frequency | Nominal Capacity | Maximum Vacuum | Maximum Pressure | Motor Power | Weight |
| 50 Hz | 750 m³/h | -200 mbar | +185 mbar | 5.5 kW | 89 kg |
| 60 Hz | 900 m³/h | -170 mbar | +150 mbar | 6.6 kW | 89 kg |

Key Features of the SV 700/1 5.5 kW
750 m³/h Airflow
High nominal 50 Hz capacity makes the blower suitable for industrial processes requiring substantial volumes of air.
Moderate Differential
The -200 mbar vacuum and +185 mbar pressure ratings provide useful operating capability without requiring the larger SV 700/1 motors.
Oil-Free Air Path
No lubricating oil is required within the compression chamber, helping provide clean process airflow.
Non-Contact Compression
The side channel principle generates differential aerodynamically without rubbing compression components in the airflow path.
Integrated Silencers
Inlet and discharge silencers are incorporated into the blower construction to help control operating noise.
Sealed Bearings
Sealed bearing construction eliminates routine bearing greasing and supports the blower’s low-maintenance design.
High-Volume Vacuum and Pressure Applications
The 5.5 kW SV 700/1 is particularly useful on systems where a large airflow is required but the normal operating differential remains within its moderate vacuum or pressure range.

› Printing and paper machinery
› Packaging equipment
› Drying systems
› Cooling airflow

SV 700/1 5.5 kW Supply and Application Support
Vacuum Pumps UK can assist with the supply of Becker SV 700/1 5.5 kW blowers for machinery replacement, maintenance requirements and new industrial installations.
Where an existing blower is being replaced, send us the complete blower and motor nameplate information. The SV 700/1 designation alone does not identify the motor configuration, and the three versions have very different permissible vacuum and pressure differentials.
For new applications, tell us the required airflow together with the normal vacuum or positive-pressure operating point. Considering the actual duty can prevent a larger motor being selected unnecessarily where the 5.5 kW configuration already provides sufficient differential capability.
Accessories for Becker SV 700/1 Installations
The connected system has a direct effect on blower performance. Correctly sized filters, relief valves and pipework help protect airflow while keeping the blower within the intended operating differential.
Inlet Filters
Correct filtration helps prevent contamination entering the blower while avoiding excessive inlet restriction.
Vacuum Relief Valves
Vacuum relief can limit excessive inlet differential if process restriction becomes greater than intended.
Pressure Relief Valves
Pressure relief provides protection if discharge resistance rises because of blocked or restricted pipework.
Installation Components
Flexible connectors, non-return valves, pipework fittings and other components can be selected to suit the installation.
Becker SV 700/1 5.5 kW Service, Repair and Spare Parts
Side channel blowers use a non-contact compression principle, but reliable operation still depends on the condition of the motor, bearings, impeller and connected system.
A dirty inlet filter, restricted pipework or incorrectly sized components can reduce airflow and increase operating differential. Investigating the installation as well as the blower itself is therefore important when performance begins to change.
If your SV 700/1 becomes noisy, develops vibration, operates hotter than expected or no longer produces the required airflow, Vacuum Pumps UK can assist with fault investigation and workshop repair.
Blower Service
Technical support for maintenance, performance checks and installation issues affecting Becker side channel blowers.
Blower Repair
Workshop assessment for noisy, damaged or under-performing blowers, including motor and bearing problems.
Spare Parts
Replacement filters and Becker spare parts are available through our sister company VacAir Superstore.
Becker SV 700/1 5.5 kW Frequently Asked Questions
What airflow does the Becker SV 700/1 5.5 kW provide?
Nominal volume flow is 750 m³/h at 50 Hz and 900 m³/h at 60 Hz.
What maximum vacuum can the 5.5 kW version achieve?
Maximum relative vacuum is -200 mbar at 50 Hz and -170 mbar at 60 Hz.
What is its maximum positive pressure?
The blower is rated to +185 mbar at 50 Hz and +150 mbar at 60 Hz.
Why are there different motor powers if the nominal airflow is the same?
The motor configurations primarily change the differential pressure capability rather than the nominal free-air volume. The 7.5 kW and 11 kW SV 700/1 versions can operate against considerably greater vacuum or positive-pressure differential.
Is the SV 700/1 5.5 kW suitable where very high pressure is required?
Its 50 Hz maximum is +185 mbar. If the system requires a substantially greater positive-pressure differential, another SV 700/1 motor configuration may be more appropriate.
Is the Becker SV 700/1 oil-free?
Yes. The side channel compression chamber operates without lubricating oil.
Can Vacuum Pumps UK help identify an existing SV 700/1?
Yes. Send us photographs of the blower and motor nameplates so we can identify the exact configuration and discuss supply, servicing or repair.
