Becker SV5.130/2 1.1kW Side Channel Blower
The Becker SV5.130/2 is a two-stage side channel blower delivering 70 m³/h nominal airflow from a 1.1kW motor, with particularly strong vacuum and pressure capability for its airflow.
At 50 Hz it develops maximum relative vacuum of -380 mbar and maximum positive pressure of +400 mbar. This makes the SV5.130/2 especially relevant where the application requires a relatively high pressure differential rather than simply a large volume of unrestricted air.
Its regenerative two-stage compression principle provides oil-free process air without using rubbing vanes within the compression chamber.

High Differential from a 70 m³/h Two-Stage Blower
The performance balance of the Becker SV5.130/2 is quite different from a blower selected mainly for high airflow. Its nominal capacity is 70 m³/h, but the two-stage arrangement allows maximum relative vacuum to reach -380 mbar and maximum positive pressure to reach +400 mbar.
This makes operating differential the significant characteristic of the SV5.130/2. On installations where air must be drawn through restrictive equipment or delivered against substantial resistance, the ability to develop pressure difference can be more important than the nominal free-air figure alone.
Within the blower, energy is transferred repeatedly from the rotating impellers to the process air. The two-stage arrangement allows the differential developed by the regenerative process to be increased before the air leaves the blower.
There is no requirement for lubricating oil within the compression chamber and the impeller system operates without the rubbing compression elements found in rotary vane equipment.
Correct selection still depends upon the actual operating point. The required flow at the intended vacuum or pressure should therefore be considered together with the resistance of the complete installation.
Becker SV5.130/2 Technical Specification
The SV5.130/2 uses a 1.1kW motor and provides 70 m³/h nominal airflow, -380 mbar maximum relative vacuum and +400 mbar maximum relative positive pressure at 50 Hz.

| SV5.130/2 | Two Stage | 70 m³/h | -380 mbar | +400 mbar | 1.1kW |
SV5.130/2 Performance and Design
70 m³/h Capacity
Moderate nominal airflow for machinery where operating differential is a more significant requirement.
-380 mbar Vacuum
Strong suction capability for restrictive vacuum systems, handling and industrial process applications.
+400 mbar Pressure
Substantial positive-pressure differential for conveying and process-air duties.
Two-Stage Compression
Successive regenerative stages enable the blower to achieve greater differential than a comparable single-stage arrangement.
1.1kW Motor
Combines relatively low motor power with strong two-stage vacuum and pressure performance.
Oil-Free Air Path
The process-air compression chamber does not require lubricating oil.
Industrial Uses for the SV5.130/2
The strong -380/+400 mbar differential makes the SV5.130/2 particularly relevant to applications where resistance within the process requires more vacuum or pressure than a conventional low-pressure blower can provide.
› Packaging machinery
› Printing and paper equipment
› Vacuum process systems
› Aeration applications
› Drying systems
› Industrial process air
Becker SV5.130/2 Supply and Replacement
When replacing an SV5.130/2, identifying the complete blower and motor specification is important because similar frame sizes can exist with different performance characteristics.
Vacuum Pumps UK can review photographs, nameplate information and details of the machine or process to help establish the required replacement.
For new applications, particular attention should be given to the operating differential. A system requiring 70 m³/h at significant vacuum or pressure is a different duty from one requiring the same airflow close to atmospheric pressure.
Becker SV5.130/2 Accessories
Correctly selected accessories are particularly important on higher-differential two-stage applications because unnecessary restriction can affect airflow and operating temperature.
Inlet Filtration
Appropriately sized filtration protects the blower while avoiding unnecessary suction restriction.
Vacuum Relief
Relief equipment can control maximum vacuum differential where process restriction varies.
Pressure Relief
Pressure relief can protect the blower against excessive discharge resistance.
System Components
Silencers, valves, flexible connections and associated installation components can be selected to suit the system.
Becker SV5.130/2 Service, Repair and Spare Parts
Higher differential operation makes good filtration, clear pipework and correct system control particularly important. Increased restriction can reduce airflow and raise blower operating temperature.
Changes in noise, vibration or performance can also indicate mechanical wear or motor problems. Vacuum Pumps UK can assist with inspection, fault diagnosis, servicing and workshop repair.
