Becker SV 1100/1 7.5 kW Side Channel Blower
The Becker SV 1100/1 7.5 kW is a high-volume single-stage side channel blower delivering 1050 m³/h at 50 Hz for industrial vacuum and positive-pressure applications.
Its 50 Hz operating limits are -160 mbar relative vacuum and +140 mbar positive pressure. At 60 Hz, the corresponding 9 kW motor increases nominal volume flow to 1250 m³/h, with maximum vacuum of -130 mbar and maximum positive pressure of +110 mbar.
This version is particularly suited to duties where a very large volume of air is required at moderate differential, rather than applications demanding the higher vacuum or pressure capability of the larger SV 1100/1 motor configurations.

High-Volume Airflow from the SV 1100/1
The 7.5 kW SV 1100/1 is principally about air volume. With a nominal capacity of 1050 m³/h at 50 Hz, it provides considerably greater airflow than the smaller fixed-speed SV single-stage models while operating within a moderate differential range.
This can make it particularly useful for processes requiring large-scale ventilation, aeration, drying, cooling, conveying or vacuum airflow where system resistance remains relatively low. Selecting this configuration allows the high nominal capacity of the SV 1100/1 to be used without automatically moving to a larger motor.
At 50 Hz the blower can operate to -160 mbar relative vacuum or +140 mbar positive pressure. The higher-powered SV 1100/1 configurations share the same nominal capacity but are designed to overcome progressively greater system differential.
The blower uses a rapidly rotating impeller to accelerate air through the side channel. Compression is produced aerodynamically rather than by rubbing compression components, and no lubricating oil is required within the process-air chamber.
When selecting the blower, the required airflow should be considered at the actual system vacuum or pressure. Filters, pipework, valves and process equipment all contribute resistance and can change the operating point considerably.

Key Features of the SV 1100/1 7.5 kW
1050 m³/h Capacity
Very high nominal airflow at 50 Hz suits industrial processes requiring large volumes of suction or blowing air.
Moderate Differential
Provides -160 mbar vacuum and +140 mbar positive pressure for high-flow applications without demanding the larger motor configurations.
Oil-Free Airflow
No lubricating oil is required in the compression chamber, helping provide clean air to the connected process.
Non-Contact Compression
Air differential is generated aerodynamically without rubbing compression components in the process-air path.
Integrated Silencers
Inlet and discharge silencers are incorporated into the blower design to help manage operating sound.
Sealed Bearings
Sealed bearing construction eliminates routine bearing greasing and contributes to low maintenance requirements.
Applications Requiring Large Air Volumes
The 7.5 kW SV 1100/1 is particularly relevant where the process requires substantial airflow but only moderate vacuum or positive-pressure differential.
› Vacuum handling systems
› Printing and paper machinery
› Packaging equipment
› Large-scale drying
› Cooling airflow

SV 1100/1 7.5 kW Supply and Application Support
Vacuum Pumps UK can assist with the supply of Becker SV 1100/1 7.5 kW blowers for machinery replacement, planned maintenance and new industrial installations.
For replacement equipment, provide both the Becker blower nameplate and motor information. The SV 1100/1 designation covers several motor configurations with the same nominal airflow but significantly different vacuum and pressure capability.
For a new installation, tell us the airflow required together with the expected working vacuum or positive pressure. This allows the 7.5 kW configuration to be considered against the real duty rather than selecting a larger motor simply because it is available.
Accessories for High-Flow SV 1100/1 Systems
With more than 1000 m³/h of nominal airflow, correct sizing of filters, valves and connecting pipework is important. Unnecessary restriction can alter the operating point and reduce the airflow available to the process.
Inlet Filters
High-flow filtration should provide appropriate contamination protection without creating excessive suction restriction.
Vacuum Relief Valves
Vacuum relief can protect the blower if inlet conditions become more restrictive than the intended system duty.
Pressure Relief Valves
Correct pressure relief helps prevent excessive differential if the discharge side becomes blocked or restricted.
Installation Components
Suitable pipework, flexible connectors and non-return valves help minimise unnecessary pressure loss in high-volume systems.
Becker SV 1100/1 7.5 kW Service, Repair and Spare Parts
The non-contact side channel principle avoids rubbing compression components, but the motor, bearings, impeller condition and surrounding system still require consideration when diagnosing performance problems.
On a high-volume installation, contamination or restriction within an inlet filter can have a noticeable effect on available airflow. Pipework condition and process changes should therefore be considered alongside the blower itself.
If an SV 1100/1 develops unusual noise, vibration, reduced airflow or excessive temperature, Vacuum Pumps UK can assist with fault investigation and workshop repair.
Blower Service

Becker SV 1100/1 7.5 kW Frequently Asked Questions
What airflow does the Becker SV 1100/1 7.5 kW provide?
Nominal volume flow is 1050 m³/h at 50 Hz and 1250 m³/h at 60 Hz.
What is its maximum relative vacuum?
Maximum vacuum is -160 mbar at 50 Hz and -130 mbar at 60 Hz.
What positive pressure can the 7.5 kW version produce?
Maximum relative pressure is +140 mbar at 50 Hz and +110 mbar at 60 Hz.
Why choose the 7.5 kW SV 1100/1?
This configuration is particularly suited where the high nominal airflow of the SV 1100/1 is required but the system does not demand the substantially greater differential capability of the larger motor versions.
Do the larger SV 1100/1 motors provide more 50 Hz nominal airflow?
No. The 7.5 kW, 11 kW and 15 kW configurations all have a nominal capacity of 1050 m³/h at 50 Hz. Their principal difference is the vacuum and pressure differential they can develop.
Does the SV 1100/1 require oil in the compression chamber?
No. Side channel compression operates without lubricating oil in the process-air chamber.
Can Vacuum Pumps UK help identify an existing blower?
Yes. Send us clear photographs of the Becker blower and motor nameplates and we can assist with identification, supply, servicing or repair.
