Becker SV 300/1 4.0 kW Side Channel Blower
The Becker SV 300/1 4.0 kW is the highest-differential fixed-speed configuration within the standard SV 300/1 single-stage family, combining 325 m³/h nominal airflow with strong vacuum and positive-pressure capability.
At 50 Hz, maximum relative vacuum is -290 mbar and maximum positive pressure is +340 mbar. At 60 Hz, the associated 4.80 kW motor increases nominal flow to 390 m³/h, with maximum vacuum of -310 mbar and maximum pressure of +320 mbar.
The 4.00 kW motor gives this version additional operating margin where the system contains significant restrictions, longer pipe runs or processes requiring stronger holding force or blast-air pressure.

Higher Differential Pressure from the SV 300/1 Platform
The 4.00 kW configuration takes the SV 300/1 platform into a more demanding operating range. Although nominal flow remains 325 m³/h at 50 Hz, the blower can tolerate a much greater pressure difference than the smaller motor versions.
Maximum relative vacuum is -290 mbar at 50 Hz, while positive-pressure capability reaches +340 mbar. At 60 Hz, maximum vacuum actually increases to -310 mbar while nominal flow rises to 390 m³/h.
This higher differential capability is useful where airflow must pass through filters, long pipework, tooling or process restrictions, or where greater holding force or discharge pressure is needed.
The side channel principle remains oil-free and non-contact. The rotating impeller accelerates the air without rubbing against the compression chamber, helping reduce internal wear and eliminating lubricating oil from the process air path.
As with all side channel blowers, the maximum rating should not be confused with the normal operating point. Correct selection should consider the airflow required at the actual vacuum or pressure imposed by the system.
Becker SV 300/1 4.00 kW Technical Specifications
The corresponding 60 Hz motor is rated at 4.80 kW and increases nominal volume flow from 325 to 390 m³/h. Vacuum and positive-pressure limits also differ between frequencies.
| Frequency | Nominal Capacity | Maximum Vacuum | Maximum Pressure | Motor Power | Weight |
| 50 Hz | 325 m³/h | -290 mbar | +340 mbar | 4.00 kW | 50 kg |
| 60 Hz | 390 m³/h | -310 mbar | +320 mbar | 4.80 kW | 50 kg |
Vacuum and pressure figures are relative. Weight includes motor.
Key Features of the SV 300/1 4.00 kW
Higher Vacuum Capability
Provides up to -290 mbar at 50 Hz and -310 mbar at 60 Hz for applications needing a stronger suction differential.
Strong Positive Pressure
Maximum pressure of +340 mbar at 50 Hz gives useful capability for blast-air, conveying and other pressure-side duties.
Oil-Free Compression
No lubricating oil is required in the compression chamber, providing clean process airflow.
Non-Contact Air Movement
The impeller creates differential pressure aerodynamically rather than through rubbing compression surfaces.
Integrated Silencing
Inlet and discharge silencers are built into the blower to help control noise and simplify machinery integration.
Industrial Installation
Sealed bearings, compact construction and pedestal mounting with vibration isolation suit a wide range of industrial machinery installations.
Applications Requiring Greater System Differential
The 4.00 kW SV 300/1 is best suited to applications where system resistance or process requirements demand more differential pressure than the smaller SV 300/1 motor configurations can provide.
› Vacuum lifting and holding
› Vacuum clamping systems
› Printing and paper machinery
› Packaging and processing equipment
› Automated material handling
› Pneumatic conveying
› Blast-air systems
› Drying processes
› Cooling and process air
› General industrial engineering
Becker SV 300/1 4.00 kW Supply and Application Support
Vacuum Pumps UK can assist with SV 300/1 4.00 kW requirements for replacement blowers, machinery maintenance and new industrial installations.
When replacing an existing SV 300/1, provide the complete blower and motor nameplates. This is particularly important because the 4.00 kW version has the same nominal flow as the smaller configurations but a significantly different operating envelope.
For new installations, provide the required flow together with the normal working vacuum or discharge pressure. System resistance, filters, pipework and valves should all be considered as part of blower selection.
Accessories for Higher-Differential SV 300/1 Systems
Higher-differential applications place greater importance on airflow protection and relief arrangements. Correct accessories can help protect the blower if process restrictions increase or airflow becomes limited.
Inlet Filters
Suitable filtration helps keep dust and contamination away from the impeller and internal air passages.
Vacuum Relief Valves
Vacuum relief can prevent excessive suction differential if filters block or process restrictions increase.
Pressure Relief Valves
Pressure relief protects the blower against excessive discharge back pressure on blast-air and conveying duties.
Installation Components
Flexible connectors, non-return valves, silencers and correctly sized pipework fittings can be incorporated into the installation.
Becker SV 300/1 4.00 kW Service, Repair and Spare Parts
The SV 300/1 uses a non-contact compression principle, but reliable operation still depends on the condition of the bearings, motor and surrounding airflow system.
On higher-differential applications, blocked filters, restricted pipework or incorrectly adjusted relief devices can place additional load on the blower and increase operating temperature. Loss of performance should therefore be investigated as a complete system issue rather than automatically assuming an internal blower fault.
Vacuum Pumps UK can assist with inspection, diagnosis, servicing and workshop repair of Becker side channel blowers.

Becker SV 300/1 4.00 kW Frequently Asked Questions
What airflow does the SV 300/1 4.00 kW provide?
Nominal capacity is 325 m³/h at 50 Hz and 390 m³/h at 60 Hz.
What is its maximum vacuum?
Maximum relative vacuum is -290 mbar at 50 Hz and -310 mbar at 60 Hz.
What is its maximum positive pressure?
The blower is rated to +340 mbar at 50 Hz and +320 mbar at 60 Hz.
Is this the highest-differential SV 300/1 fixed-speed version?
Yes, within the standard 2.20, 3.00 and 4.00 kW fixed-speed configurations it provides the greatest vacuum and pressure capability.
Why is airflow the same as the smaller motor versions?
The larger motor does not primarily increase the nominal free-air flow. Its main benefit is allowing the blower to operate against a greater pressure differential.
Is the SV 300/1 oil-free?
Yes. No lubricating oil is used in the air compression chamber.
Should the blower be selected by maximum pressure alone?
No. The correct selection depends on the airflow required at the actual operating vacuum or pressure. Maximum values are limits rather than normal duty points.
Can Vacuum Pumps UK help replace an existing SV 300/1?
Yes. Send us a clear photograph of the blower and motor nameplates and we can help identify the correct configuration and discuss supply, servicing or repair.
