Becker SV 201/1 2.20 kW Side Channel Blower
The Becker SV 201/1 2.20 kW is the highest-differential motor configuration in the SV 201/1 single-stage range, combining 190 m³/h nominal airflow with strong vacuum and positive-pressure capability.
At 50 Hz the blower operates to -275 mbar relative vacuum and +340 mbar positive pressure. At 60 Hz, the corresponding 2.65 kW configuration increases nominal capacity to 230 m³/h and provides maximum vacuum of -285 mbar and maximum pressure of +330 mbar.
These operating limits make the 2.20 kW version particularly suited to systems where substantial pipework resistance, holding force, conveying pressure or blast-air differential must be overcome while retaining the simple, oil-free side channel operating principle.

Becker SV 201/1 2.20 kW High-Differential Performance
The 2.20 kW SV 201/1 is designed for applications where the blower must maintain useful airflow while working against substantially greater system resistance than the lower-powered versions can accommodate.
Nominal flow remains 190 m³/h at 50 Hz, but maximum vacuum increases to -275 mbar and positive pressure rises to +340 mbar. This clearly illustrates why motor power is an essential part of the SV 201/1 model identification rather than a secondary specification.
Air movement is generated by a high-speed impeller acting within the side channel. As the air circulates around the blower, energy is progressively transferred to it to create the required pressure difference. The impeller operates without physical rubbing contact in the compression chamber.
Because there are no sliding compression vanes and no lubricating oil in the air chamber, the blower provides clean process airflow and low routine maintenance requirements. Integrated silencers and sealed bearings further simplify installation and ongoing operation.
For demanding vacuum or pressure duties, the actual operating point should always be considered. Maximum figures indicate the limits of the blower but do not replace checking the required airflow at the intended pressure differential.
Becker SV 201/1 2.20 kW Technical Specifications
The corresponding 60 Hz motor is rated at 2.65 kW and increases nominal airflow to 230 m³/h. Unlike the smaller configurations, maximum vacuum also increases slightly at 60 Hz.

Key Features of the SV 201/1 2.20 kW
High Vacuum Capability
Maximum vacuum reaches -275 mbar at 50 Hz and -285 mbar at 60 Hz, giving this version the strongest suction performance in the SV 201/1 family.
Strong Positive Pressure
Up to +340 mbar at 50 Hz provides significant pressure capability for conveying, blowing and process-air applications.
Oil-Free Process Air
No lubrication oil is used within the compression chamber, helping keep the conveyed air free of pump oil contamination.
Non-Contact Compression
Pressure is generated aerodynamically rather than through rubbing mechanical compression elements.
Integrated Silencing
Built-in inlet and discharge silencers reduce the need for additional silencing components in many installations.
Industrial Construction
Compact horizontal mounting, sealed bearings and vibration isolation suit continuous industrial machinery applications.
Applications for the SV 201/1 2.20 kW
The higher vacuum and pressure capability of the 2.20 kW configuration allows it to serve duties where greater holding force, conveying differential or system resistance must be overcome while maintaining continuous airflow.
› Vacuum lifting and holding
› Vacuum fixtures and clamping
› Printing and paper machinery
› Packaging and process equipment
› Automated handling systems

Becker SV 201/1 2.20 kW Supply and Application Support
Vacuum Pumps UK can assist with SV 201/1 2.20 kW blower requirements for both replacement and new equipment installations.
Where the blower is already installed, send us the complete Becker nameplate and motor details. This helps distinguish the 2.20 kW configuration from the lower-powered SV 201/1 versions, which have similar nominal airflow but considerably lower vacuum and pressure limits.
For application selection, provide the required airflow together with the normal operating vacuum or discharge pressure. Pipework length, filters, valves and process restrictions can all influence the duty seen by the blower and should be considered when selecting equipment.
Accessories for Higher-Differential SV 201/1 Installations
On higher-vacuum and higher-pressure applications, correct filtration and relief protection become especially important. A side channel blower depends on adequate airflow for cooling as well as process performance, so severe restriction should be avoided.
Inlet Filters
Filter housings and suitable elements protect the impeller and side channel from contamination without unnecessarily restricting airflow.
Vacuum Relief Valves
Vacuum relief can prevent excessive inlet differential if a valve closes, a filter blocks or process conditions change unexpectedly.
Pressure Relief Valves
Pressure relief protects the blower if discharge resistance drives the system beyond the permitted positive-pressure operating range.
Pipework and Connections
Flexible connectors, non-return valves, silencers and correctly sized pipework components can be selected around the blower duty.
Becker SV 201/1 2.20 kW Service, Repair and Spare Parts
The side channel compression principle is non-contact and relatively low maintenance, but the blower still relies on sound bearings, a healthy motor and unrestricted airflow through the connected system.
On higher-differential duties, blocked filters or closed pipework can impose additional load and increase operating temperature. Unusual noise, vibration, declining airflow or an inability to reach the expected duty should therefore be investigated rather than ignored.
Vacuum Pumps UK can assist with technical diagnosis, inspection and workshop repair of Becker side channel blowers, including assessing whether poor performance originates from the blower itself or the surrounding system.
Blower Service
Technical support for Becker SV blower maintenance, performance checks and operating-condition problems.
Blower Repair
Workshop assessment for damaged, noisy or under-performing blowers, including bearing and motor-related faults.
Spare Parts
Replacement filters and Becker spare parts are available through our sister company VacAir Superstore.
Becker SV 201/1 2.20 kW Frequently Asked Questions
What is the airflow of the SV 201/1 2.20 kW?
Nominal capacity is 190 m³/h at 50 Hz and 230 m³/h at 60 Hz.
What maximum vacuum can it achieve?
The blower is rated to -275 mbar relative vacuum at 50 Hz and -285 mbar at 60 Hz.
What is its maximum positive pressure?
Maximum positive pressure is +340 mbar relative at 50 Hz and +330 mbar at 60 Hz.
Is this the strongest SV 201/1 motor version?
Within these standard SV 201/1 motor configurations, yes. It provides the greatest vacuum and positive-pressure differential.
Why does the 2.20 kW version have the same nominal flow as the smaller motors?
The larger motor allows the blower to maintain operation against a greater differential pressure. Nominal free airflow alone does not describe the complete performance capability.
Is it oil-free?
Yes. No lubricating oil is used in the compression chamber.
Should a high-pressure application use a relief valve?
Relief protection may be important where process restrictions could cause the blower to exceed its permitted differential pressure. The exact system arrangement should be considered during installation.
Can Vacuum Pumps UK help with an existing SV 201/1?
Yes. Send us the complete blower and motor nameplate details and we can help identify the configuration and discuss supply, service or repair requirements.
