Becker SV8.130/2 1.25kW Side Channel Blower
The Becker SV8.130/2 is a compact two-stage side channel blower combining 65 m³/h nominal capacity with maximum relative pressure of +425 mbar and maximum relative vacuum of -300 mbar.
Powered by a 1.25kW motor at 50 Hz, the SV8.130/2 is particularly notable for the pressure differential developed from a comparatively small motor and airflow specification. It can therefore be relevant to smaller process systems requiring moderate air volume against significant resistance.
The regenerative compression chamber operates without sliding vanes and without oil lubrication in the process-air path.
Vacuum Pumps UK can assist with Becker blower supply, identification and replacement.

Compact Airflow with Substantial Positive Pressure
The performance profile of the SV8.130/2 is unusual enough to distinguish it clearly from many of the larger older Becker side channel blowers. Its nominal airflow is only 65 m³/h, but maximum relative positive pressure reaches +425 mbar.
For an application designer, this means the model is more appropriately considered where a relatively small quantity of air must be moved against resistance than where high free-air volume is the principal requirement.
The two-stage regenerative arrangement makes this possible. Energy is repeatedly transferred from the rotating impeller to the air within the side channel, progressively developing differential before the air passes through the second stage.
On the suction side, the SV8.130/2 can develop maximum relative vacuum of -300 mbar. This allows the same blower technology to be considered for smaller vacuum handling, extraction and machine suction duties.
Because there is no physical contact between a vane and compression chamber, the operating principle differs substantially from a dry-running rotary vane vacuum pump. The process-air chamber also requires no lubricating oil.
SV8.130/2 50 Hz Performance
The 1.25kW Becker SV8.130/2 is listed with 65 m³/h nominal capacity, -300 mbar maximum relative vacuum and +425 mbar maximum relative positive pressure.
| Model | Stage | Nominal Capacity | Maximum Vacuum | Maximum Pressure | Motor Power |
| SV8.130/2 | Two Stage | 65 m³/h | -300 mbar | +425 mbar | 1.25kW |
Actual airflow reduces as the operating differential increases, so selection should be based upon the required operating point rather than nominal capacity alone.
Why the SV8.130/2 Specification Is Distinctive
65 m³/h Flow
A compact air capacity for smaller machinery and process systems.
+425 mbar Pressure
Strong pressure capability relative to the blower’s nominal air volume and motor rating.
-300 mbar Vacuum
Allows the SV8.130/2 to perform useful suction duties as well as positive-pressure applications.
Two Regenerative Stages
The staged design enables a relatively high differential to be developed from a compact blower.
1.25kW Motor
The listed 50 Hz specification uses a comparatively modest 1.25kW drive motor.
Non-Contact Compression
No rubbing carbon vanes are required within the regenerative compression chamber.
Typical Uses for the SV8.130/2
The relatively low airflow and strong pressure capability can make the SV8.130/2 particularly useful on smaller machines where resistance is significant but very high air volume is unnecessary.
› Air knives and drying
› Aeration
› Process-air supply
› Packaging machinery
› Printing equipment

SV8.130/2 Identification and Replacement
When replacing an older side channel blower, the complete identification plate is more useful than relying solely upon the basic SV8 model designation. Motor details, electrical specification, port arrangement and the application itself can all be relevant.
Send us photographs showing the complete SV8.130/2 and clear close-ups of its blower and motor plates. If the original blower remains operational, information about how it performs within the machine can also help establish the replacement duty.
For a new application, blower selection should consider required airflow at the actual vacuum or pressure differential rather than simply selecting from nominal capacity.
SV8.130/2 Installation Accessories
Because this model can develop significant differential, system restriction and protection should be considered carefully. Suitable accessories can help maintain reliable operation.
Filters
Protect the blower from contamination while avoiding excessive inlet restriction.
Relief Valves
Can prevent the blower from operating beyond the intended pressure or vacuum differential.
Silencers
Suitable acoustic components can reduce inlet or discharge noise where required.
Connections
Correctly sized pipework and fittings minimise avoidable losses within the air system.
Becker SV8.130/2 Service and Repair
Although regenerative compression is non-contact, the blower still contains bearings and other mechanical components that can deteriorate after extended service.
Unusual bearing noise, vibration, increased operating temperature or reduced process performance can indicate that the blower or its surrounding system requires investigation. Blocked filters and changes in pipework resistance should also be considered.
