Becker SV 130/2 0.55 kW Side Channel Blower
The Becker SV 130/2 0.55 kW is a compact double-stage side channel blower providing 70 m³/h nominal airflow at 50 Hz with increased vacuum and pressure differential compared with lower-stage air-moving duties.
At 50 Hz the blower is rated to -170 mbar relative vacuum and +160 mbar positive pressure. At 60 Hz the corresponding 0.66 kW motor raises nominal volume flow to 85 m³/h, with maximum vacuum of -150 mbar and maximum pressure of +140 mbar.
The double-stage arrangement allows the airflow to gain additional pressure energy through successive side channel stages, making this configuration particularly useful where moderate airflow must be maintained against greater system resistance.

Compact Double-Stage Performance
The SV 130/2 0.55 kW combines a relatively modest 70 m³/h nominal flow with the increased differential capability of a double-stage side channel arrangement. This makes it quite different in character from a single-stage blower selected mainly for higher free-air volume.
Air passes through successive side channel stages where energy is transferred from the rotating impeller into the gas. The additional stage increases the available vacuum or positive-pressure differential without requiring a mechanically contacting compression principle.
At 50 Hz the blower can operate to -170 mbar relative vacuum or +160 mbar positive pressure. This can suit compact machinery, handling systems and process equipment where moderate airflow is sufficient but the connected system creates appreciable resistance.
The air chamber is oil-free and the compression principle is non-contact. There are no rubbing vanes or other contacting compression elements within the process-air path.
As with any side channel blower, the correct selection should be based on the required flow at the actual operating differential rather than nominal capacity alone.
Becker SV 130/2 0.55 kW Technical Specifications
At 50 Hz the corresponding 0.55 kW motor increases nominal volume flow to 70 m³/h. Maximum relative vacuum is -170 mbar and maximum positive pressure is +160 mbar.
| Frequency | Nominal Capacity | Maximum Vacuum | Maximum Pressure | Motor Power | Weight |
| 50 Hz | 70 m³/h | -170 mbar | +160 mbar | 0.55 kW | 21.5 kg |
| 60 Hz | 85 m³/h | -150 mbar | +140 mbar | 0.66 kW | 21.5 kg |
Vacuum and pressure figures are relative. Weight includes motor.
Key Features of the SV 130/2 0.55 kW
Double-Stage Design
Two successive side channel stages provide greater operating differential than a comparable single-stage high-flow arrangement.
Compact 70 m³/h Duty
Suitable for machinery and process systems requiring moderate airflow combined with useful suction or blowing pressure.
Oil-Free Airflow
No lubricating oil is required within the compression chamber, helping provide clean process air.
Non-Contact Compression
Pressure and vacuum are produced aerodynamically without rubbing compression elements within the air chamber.
Integrated Silencers
Inlet and discharge silencers are integrated into the blower construction to help manage operating noise.
Sealed Bearings
Sealed bearings eliminate routine bearing greasing and contribute to low routine maintenance requirements.
Compact Vacuum and Pressure Applications
The 0.55 kW SV 130/2 is suited to applications where the required airflow is relatively modest but the system needs more differential than a simple low-pressure air-moving duty.

› Vacuum fixing
› Printing and paper machinery
› Packaging equipment

SV 130/2 0.55 kW Supply and Application Support
Vacuum Pumps UK can assist with Becker SV 130/2 0.55 kW supply for replacement machinery, maintenance requirements and new industrial applications.
When replacing an existing blower, send us the full Becker model and motor nameplate details. The SV 130/2 is available with different motor configurations and each has a different vacuum and pressure capability despite sharing the same nominal flow.
For a new application, provide the required airflow together with the normal operating vacuum or positive pressure. This helps ensure the blower is selected for the real duty rather than simply from the model designation.
Accessories for Becker SV 130/2 Systems
Correct filtration, relief protection and pipework help maintain the intended operating point and protect the blower from excessive system restriction.
Inlet Filters
Appropriate filtration helps protect the blower from contamination while limiting unnecessary suction restriction.
Vacuum Relief Valves
Vacuum relief can protect the blower if process restriction increases beyond the intended duty.
Pressure Relief Valves
Pressure relief helps protect the blower where blocked or restricted discharge pipework could increase differential.
Installation Components
Flexible connectors, non-return valves and correctly sized pipework can be incorporated into the complete installation.
Becker SV 130/2 0.55 kW Service, Repair and Spare Parts
The side channel principle uses non-contact compression, but the motor, bearings, impeller condition and connected process can all affect blower performance.
Dirty filters or restricted pipework can increase the operating differential and reduce available airflow. The surrounding installation should therefore be considered when diagnosing a blower that has become hotter, noisier or less effective.
Vacuum Pumps UK can assist with investigation, servicing and workshop repair of Becker SV side channel blowers.
Blower Service
Technical support for Becker blower maintenance and performance issues.
Blower Repair
Workshop inspection and repair assessment for noisy, damaged or under-performing units.
Spare Parts
Becker spare parts and replacement filters are available through our sister company VacAir Superstore.
Becker SV 130/2 0.55 kW Frequently Asked Questions
What airflow does the Becker SV 130/2 0.55 kW provide?
Nominal volume flow is 70 m³/h at 50 Hz and 85 m³/h at 60 Hz.
What maximum vacuum can it achieve?
Maximum relative vacuum is -170 mbar at 50 Hz and -150 mbar at 60 Hz.
What is the maximum positive pressure?
The blower is rated to +160 mbar at 50 Hz and +140 mbar at 60 Hz.
What does double stage mean?
The airflow passes through two side channel compression stages, allowing a greater pressure differential to be developed than would normally be available from a comparable single-stage arrangement.
Does the SV 130/2 use oil in the compression chamber?
No. The blower uses oil-free side channel compression.
Why are there different motor powers for the same SV 130/2 model?
The different motors allow the blower to operate against different vacuum and positive-pressure differentials while retaining the same nominal 50 Hz capacity.
Can Vacuum Pumps UK help identify my existing SV 130/2?
Yes. Send us the blower and motor nameplate details and we can assist with identification, replacement supply, service or repair.
