Becker SV 130/1 1.25 kW Side Channel Blower
The Becker SV 130/1 1.25 kW is a higher-differential single-stage side channel blower providing oil-free vacuum or positive-pressure air for industrial machinery and process applications.
With a nominal flow of 130 m³/h at 50 Hz, this configuration can reach -240 mbar relative vacuum or +240 mbar positive pressure. For 60 Hz operation, the corresponding 1.50 kW motor provides 160 m³/h, with a maximum vacuum of -245 mbar and maximum pressure of +235 mbar.
The combination of compact dimensions, non-contact compression and increased differential-pressure capability makes the 1.25 kW version particularly useful where an SV 130/1 must overcome greater system resistance while maintaining continuous airflow.

Becker SV 130/1 1.25 kW Overview
The SV 130/1 1.25 kW uses a rotating impeller and side channel to create its pressure differential. Air is repeatedly accelerated as it travels around the blower housing, allowing vacuum to be generated at the inlet or positive pressure at the discharge.
This aerodynamic compression method requires no oil in the compression chamber and avoids normal rubbing contact between compression components. The result is clean airflow and a relatively simple blower design with low routine maintenance requirements.
Although nominal capacity remains 130 m³/h at 50 Hz, the 1.25 kW motor allows the blower to reach -240 mbar vacuum or +240 mbar pressure. This is a significant distinction when comparing it with other SV 130/1 motor versions and is why motor power should always be confirmed when identifying an existing blower.
Becker incorporates inlet and discharge silencers into the SV design, while sealed bearings eliminate routine bearing greasing. The horizontal pedestal arrangement also makes the unit suitable for integration into production machinery where installation space and accessibility are important.
Vacuum Pumps UK can help with an existing SV 130/1 or discuss the required duty for a new installation. Where possible, provide both the required airflow and the normal operating vacuum or pressure rather than simply the maximum figure.
Becker SV 130/1 1.25 kW Technical Specifications
At 60 Hz, this SV 130/1 uses the corresponding 1.50 kW motor and operates at a higher nominal volume flow. The vacuum and pressure limits also change slightly, so electrical frequency should be established when comparing specifications.
| Frequency | Nominal Capacity m³/h |

Maximum Pressure mbar |
Motor Power kW |
Noise Level dB(A) |
| 50 Hz | 130 | -240 | +240 | 1.25 | 63.4–64.2 |

Weight: 24.5 kg with motor.
Vacuum and pressure values are relative. Becker’s vacuum and pressure product listings publish slightly different noise values, so the range of published figures is shown.
Becker SV 130/1 1.25 kW Features
Higher Vacuum Capability
The 1.25 kW configuration can operate to -240 mbar relative vacuum at 50 Hz for applications requiring a greater suction differential.
Positive Pressure Operation
The same blower configuration is rated to +240 mbar at 50 Hz when used to provide positive-pressure or blast air.
Dry Compression
Oil is not required within the compression chamber, making the SV suitable where clean process airflow is desirable.
Contact-Free Air Movement
The impeller generates airflow without rubbing against the surrounding compression chamber during normal operation.
Integrated Noise Reduction
Inlet and discharge silencers are incorporated into the blower to help control operating noise and simplify machine installation.
Low Routine Maintenance
The non-contact operating principle and sealed bearings minimise routine lubrication and mechanical maintenance requirements.
Typical Becker SV 130/1 1.25 kW Applications
The higher differential pressure available from this SV 130/1 configuration makes it suitable for machinery where pipework resistance, process conditions or the required suction force places a greater load on the blower.
› Printing and paper transport
› Vacuum conveying
› Packaging machinery
› Vacuum fixtures and holding
› Component handling systems
› Blast-air applications
› Pneumatic conveying

Becker SV 130/1 1.25 kW Blower Supply
Vacuum Pumps UK can assist with Becker SV 130/1 1.25 kW blower requirements for existing machinery and new industrial applications.
When replacing an installed unit, it is important to establish more than the basic SV 130/1 model number. Motor power, frequency and electrical information should also be checked because the different SV 130/1 motor configurations have significantly different operating limits.
A clear photograph of the blower and motor nameplates is normally the easiest starting point. For new applications, provide the required flow, normal operating vacuum or pressure and details of the process so our team can help assess the duty.

Becker SV Side Channel Blower Accessories
Correct accessory selection is especially important where a side channel blower is operating at higher differential pressures. Filtration protects the blower from contamination, while vacuum or pressure relief devices can prevent the system driving the blower beyond its permitted operating range.
Inlet Filters
Air filtration helps protect the blower from dust and other contaminants that could accumulate in the impeller, side channel or connecting pipework.
Vacuum Relief Valves
A vacuum relief valve can limit suction differential and provide protection if an inlet restriction or process condition causes vacuum to rise excessively.
Pressure Relief Valves
For pressure operation, relief protection can prevent excessive discharge pressure caused by restrictions, closed valves or changing process conditions.
Installation Accessories
Non-return valves, flexible connectors, silencers and pipework components can be selected to suit the blower and surrounding system.
Becker SV 130/1 Service, Repair and Spare Parts
The contact-free compression principle means Becker SV blowers have relatively few routine service requirements. Over time, however, bearing condition, motor problems, contamination or operating outside the intended duty can affect noise, temperature and blower performance.
A reduction in suction or pressure does not necessarily mean the blower itself has failed. Blocked filters, restricted pipework, leaking connections or incorrectly set relief devices can also alter the performance of the complete system.
Vacuum Pumps UK can assist with fault diagnosis, inspection and repair of Becker side channel blowers and can advise on service requirements where an installed SV 130/1 is no longer operating as expected.
Blower Service
Technical support for Becker SV blowers, including investigation of operating performance, contamination and maintenance requirements.
Blower Repair
Workshop assessment for blowers suffering from excessive noise, vibration, motor problems, bearing wear or reduced performance.
Spare Parts
Filters and spare parts for Becker vacuum pumps and side channel blowers are available through our sister company VacAir Superstore.
Becker SV 130/1 1.25 kW Frequently Asked Questions
What is the capacity of the Becker SV 130/1 1.25 kW?
Nominal capacity is 130 m³/h at 50 Hz. At 60 Hz, the corresponding 1.50 kW configuration provides 160 m³/h.
How much vacuum can the 1.25 kW version produce?
Maximum relative vacuum is -240 mbar at 50 Hz and -245 mbar at 60 Hz.
What is its maximum positive pressure?
The maximum relative pressure is +240 mbar at 50 Hz. At 60 Hz the corresponding figure is +235 mbar.
Why are there several SV 130/1 pages?
The SV 130/1 is available with different motor powers. Although nominal airflow may be the same, maximum vacuum and pressure capability varies with the motor configuration.
Is the air from the SV 130/1 oil-free?
The compression chamber operates without oil, so oil is not introduced into the process airflow by the compression mechanism.
What maintenance does a side channel blower require?
The non-contact operating principle and sealed bearings keep routine maintenance requirements low, although filters and the overall installation should still be inspected and maintained appropriately.
Can VPUK help if I only have an old blower nameplate?
Yes. Send us a clear photograph showing the Becker model, motor power and electrical details and we can use that information to help identify the requirement.
Do you repair Becker SV blowers?
