Becker SV 300/2 3 kW Side Channel Blower
The Becker SV 300/2 3 kW is a high-differential double-stage side channel blower combining 160 m³/h nominal capacity with up to +515 mbar positive pressure and -405 mbar relative vacuum at 50 Hz.
At 60 Hz the corresponding 3.6 kW motor increases nominal volume flow to 190 m³/h. Maximum relative vacuum is -410 mbar, while maximum positive pressure is +450 mbar.
The additional motor power allows this SV 300/2 configuration to work against substantially greater system resistance than the 2.2 kW version without increasing its nominal 50 Hz free-air capacity.

High-Differential Performance from the SV 300/2
The Becker SV 300/2 3 kW is the higher-differential motor configuration within this fixed-speed SV 300/2 pairing. Although nominal capacity remains 160 m³/h at 50 Hz, maximum positive pressure rises to +515 mbar and maximum relative vacuum reaches -405 mbar.
This distinction is important when selecting between motor versions. The larger motor is not principally there to increase free-air volume; it allows the blower to work against considerably greater resistance while operating within its intended performance range.
The double-stage side channel arrangement repeatedly transfers energy from the rotating impeller into the process air. After passing through the first stage, the air is directed through a second side channel where additional differential can be developed.
Compression remains non-contact and oil-free. There are no rubbing vanes in the process-air chamber and no lubricating oil is required within the compression path, providing clean airflow for industrial vacuum and pressure applications.
The +515 mbar maximum pressure makes system design particularly important. Pipe diameter, filters, valves, discharge restrictions and relief protection all affect the actual operating point and blower load.
Becker SV 300/2 3 kW Technical Specifications
At 50 Hz the corresponding motor rating is 3 kW and nominal capacity increases to 160 m³/h. Maximum vacuum is -405 mbar relative and maximum positive pressure is +515 mbar.
| Frequency | Nominal Capacity | Maximum Vacuum | Maximum Pressure | Motor Power | Weight |
| 50 Hz | 160 m³/h | -405 mbar | +515 mbar | 3 kW | 45 kg |
| 60 Hz | 190 m³/h | -410 mbar | +450 mbar | 3.6 kW | 45 kg |

Key Features of the SV 300/2 3 kW
+515 mbar Pressure
High 50 Hz positive-pressure capability makes this version suitable for restrictive conveying, blowing and process-air systems.
-405 mbar Vacuum
Strong suction differential supports demanding vacuum handling, holding and industrial process applications.
Double-Stage Compression
Two successive side channel stages allow substantially greater differential than a single-stage blower arrangement.
Oil-Free Air Path
No lubricating oil is required within the compression chamber, helping provide clean process airflow.
Non-Contact Operation
The impeller operates without rubbing compression elements, reducing routine mechanical wear in the process-air chamber.
Integrated Silencers
Inlet and discharge silencers are incorporated into the blower construction to help manage operating sound.
High-Differential Vacuum and Pressure Applications
The 3 kW SV 300/2 is particularly suited to applications where a nominal 160 m³/h airflow must be combined with substantial suction or discharge differential.
› Pneumatic conveying
› Blast-air systems
› Aeration equipment
› Industrial drying
› Restrictive process-air systems
› Vacuum lifting and handling
› Vacuum clamping and fixing
› Printing and paper machinery
› Packaging equipment
› General industrial machinery
SV 300/2 3 kW Supply and Duty Selection
Vacuum Pumps UK can assist with Becker SV 300/2 3 kW supply for replacement machinery and new industrial vacuum or pressure installations.
For an existing unit, send us the complete Becker blower and motor nameplate details. The 2.2 kW and 3 kW versions share the same nominal 50 Hz capacity but offer substantially different maximum differential performance, so confirming the motor configuration is important.
For a new installation, provide the required airflow at the normal operating vacuum or positive pressure. This allows the blower to be considered against the actual duty rather than simply the nominal free-air capacity.
On higher-differential applications, pipework, filters, valves and relief protection are particularly important because additional restriction can increase blower load and operating temperature.
Accessories for High-Differential SV 300/2 Systems
Correct system design becomes increasingly important as blower differential rises. Filters, pipework and protection devices should be selected to support the required duty without introducing avoidable restriction.
Inlet Filters
Suitable filtration protects the blower from airborne contamination while minimising unnecessary suction-side pressure loss.
Vacuum Relief Valves
Vacuum relief can limit excessive differential if the inlet or process becomes more restrictive than intended.
Pressure Relief Valves
Pressure relief is particularly relevant on high-pressure duties where a blocked discharge could rapidly increase differential.
Installation Accessories
Flexible connectors, non-return valves and suitably sized pipework can be incorporated into the complete blower system.
Becker SV 300/2 3 kW Service, Repair and Spare Parts
The SV 300/2 uses non-contact compression, but the complete blower still relies on the condition of the motor, bearings, impeller and connected system for reliable operation.
On a high-differential configuration such as the 3 kW model, a dirty filter, restricted pipework or process blockage can have a significant effect on operating load and temperature. The system should therefore be considered as part of any blower fault investigation.
Vacuum Pumps UK can assist with Becker SV servicing, performance problems, fault diagnosis and workshop repair.
Blower Service
Technical support for Becker blower maintenance, performance checks and system-related operating problems.
Blower Repair
Workshop assessment for noisy, damaged, overheating or under-performing Becker SV side channel blowers.
Spare Parts
Becker spare parts and replacement filtration are available through our sister company VacAir Superstore.
Becker SV 300/2 3 kW Frequently Asked Questions
What airflow does the Becker SV 300/2 3 kW provide?
Nominal volume flow is 160 m³/h at 50 Hz and 190 m³/h at 60 Hz.
What maximum vacuum can the SV 300/2 3 kW produce?
Maximum relative vacuum is -405 mbar at 50 Hz and -410 mbar at 60 Hz.
What is the maximum positive pressure?
Maximum relative pressure is +515 mbar at 50 Hz and +450 mbar at 60 Hz.
How does the 3 kW version differ from the 2.2 kW SV 300/2?
Both have the same nominal 160 m³/h capacity at 50 Hz, but the 3 kW configuration provides considerably greater maximum differential. Vacuum increases from -350 to -405 mbar and positive pressure increases from +330 to +515 mbar.
Why does the larger motor not increase the 50 Hz nominal airflow?
The additional motor power allows the blower to operate against greater system differential rather than increasing the nominal free-air capacity.
Does the SV 300/2 require oil in the compression chamber?
No. Side channel compression is oil-free and non-contact within the process-air path.
Can Vacuum Pumps UK help select between the SV 300/2 motor versions?
Yes. Provide the required airflow and normal operating vacuum or pressure, or send us the nameplate details of an existing blower, and we can assist with selection and supply.
