Becker SV 1100/1 15 kW Side Channel Blower
The Becker SV 1100/1 15 kW is the highest-powered fixed-speed configuration in the SV 1100/1 family, combining 1050 m³/h nominal 50 Hz airflow with strong vacuum and positive-pressure capability.
At 50 Hz the blower is rated to -320 mbar relative vacuum and +390 mbar positive pressure. At 60 Hz, the corresponding 18 kW motor increases nominal volume flow to 1250 m³/h, with maximum vacuum of -320 mbar and maximum positive pressure of +350 mbar.
The combination of large volume flow and substantial differential makes this configuration particularly relevant where air must be moved through restrictive conveying, aeration, blast-air or industrial process systems.

Strong Differential Performance at High Airflow
The 15 kW SV 1100/1 extends the high-volume capability of the series into applications requiring substantially greater pressure differential. Nominal flow remains 1050 m³/h at 50 Hz, but the available motor power enables operation to +390 mbar positive pressure and -320 mbar relative vacuum.
This is particularly significant on the pressure side. Air moving through conveying lines, aeration equipment, process machinery or restrictive pipework creates resistance, and the blower must generate sufficient differential to maintain the required operating flow.
The 15 kW configuration therefore provides a very different operating capability from the 7.5 kW SV 1100/1 despite both sharing the same nominal free-air capacity. Selecting between them should be based on the actual duty point rather than model size alone.
The SV 1100/1 produces pressure or vacuum through a contactless rotating impeller and side channel. With no rubbing compression components and no lubricating oil required within the air chamber, the process airflow remains oil-free.
At these higher differential levels, system design deserves particular attention. Pipe diameter, filter condition, valves, process restriction, relief protection and cooling airflow can all influence operating temperature, motor load and delivered airflow.
Becker SV 1100/1 15 kW Technical Specifications
At 50 Hz the corresponding motor rating is 15 kW and nominal capacity rises to 1050 m³/h. Maximum vacuum remains -320 mbar relative, while maximum positive pressure is +390 mbar.
| Frequency | Nominal Capacity | Maximum Vacuum | Maximum Pressure | Motor Power | Weight |
| 50 Hz | 1050 m³/h | -320 mbar | +390 mbar | 15 kW | 157 kg |
| 60 Hz | 1250 m³/h | -320 mbar | +350 mbar | 18 kW | 157 kg |
Vacuum and pressure figures are relative. Weight includes motor.
Key Features of the SV 1100/1 15 kW
+390 mbar Pressure
Strong 50 Hz positive-pressure capability suits demanding blast-air, conveying and process-air applications.
-320 mbar Vacuum
Substantial suction differential extends the SV 1100/1 into more restrictive industrial vacuum duties.
1050 m³/h Airflow
Combines strong differential capability with the high nominal volume flow of the SV 1100/1 platform.
Oil-Free Process Air
The compression chamber requires no lubricating oil, helping protect processes requiring clean airflow.
Integrated Silencers
Inlet and discharge silencers are integrated into the blower construction to help manage operating noise.
Non-Contact Design
The impeller develops differential aerodynamically without rubbing compression elements in the air path.
Demanding High-Flow Vacuum and Pressure Duties
The 15 kW configuration is particularly valuable where substantial volume flow must be maintained while overcoming greater vacuum or discharge-side resistance.

SV 1100/1 15 kW Supply and Application Support
Vacuum Pumps UK can assist with Becker SV 1100/1 15 kW blower supply for replacement equipment, industrial machinery and new vacuum or positive-pressure installations.
When replacing an existing unit, provide both the Becker blower nameplate and motor details. This helps ensure that the high-differential 15 kW configuration is correctly identified rather than selecting from the common SV 1100/1 model designation alone.
For new systems, tell us the airflow required at the normal operating vacuum or pressure. At these higher differential levels, information about pipework, filtration, valves and process resistance can also be useful when considering the correct blower duty.
Accessories for High-Differential SV 1100/1 Installations
Correct accessory and pipework selection becomes increasingly important as blower differential rises. Restriction created by undersized components or contaminated filters can consume useful performance and increase operating load.
Inlet Filters
Correctly sized filtration protects the blower while minimising additional restriction at high volume flow.
Vacuum Relief Valves
Vacuum relief can protect against excessive suction differential caused by blocked filters or process restriction.
Pressure Relief Valves
Pressure relief is particularly important where discharge blockage or valve closure could drive the blower beyond the intended duty.
Installation Components
Adequately sized pipework, flexible connectors and non-return valves help minimise avoidable pressure losses.
Becker SV 1100/1 15 kW Service, Repair and Spare Parts
The SV 1100/1 uses non-contact side channel compression, but dependable operation at higher differential still depends on the bearings, motor, impeller condition and the design and condition of the complete installation.
Dirty filtration, undersized pipework, closed valves or process blockage can increase differential and operating temperature. On a high-powered blower, checking the surrounding system is therefore an important part of diagnosing an apparent performance problem.
If an SV 1100/1 becomes unusually hot or noisy, develops vibration or no longer provides the expected airflow or pressure, Vacuum Pumps UK can assist with investigation and workshop repair.

Becker SV 1100/1 15 kW Frequently Asked Questions
What airflow does the Becker SV 1100/1 15 kW provide?
Nominal volume flow is 1050 m³/h at 50 Hz and 1250 m³/h at 60 Hz.
What is the maximum relative vacuum?
Maximum relative vacuum is -320 mbar at both 50 Hz and 60 Hz.
What is the maximum positive pressure?
The blower is rated to +390 mbar at 50 Hz and +350 mbar at 60 Hz.
How does the 15 kW SV 1100/1 differ from the 11 kW version?
Both provide 1050 m³/h nominal capacity at 50 Hz, but the 15 kW configuration has greater maximum differential, particularly on positive pressure where its rating increases from +260 mbar to +390 mbar.
Why does the 15 kW version not have a higher nominal 50 Hz capacity?
The additional motor power is primarily used to enable operation against greater vacuum or pressure differential rather than to increase the nominal free-air volume.
Should the blower normally operate at +390 mbar?
The +390 mbar figure is the maximum relative pressure rating, not automatically the correct normal operating point. Selection should be based on the airflow required at the actual system differential.
Can Vacuum Pumps UK help with servicing or replacing an SV 1100/1?
