Becker SV 5.90/2 0.37kW Side Channel Blower
The Becker SV 5.90/2 is a compact double-stage side channel blower providing 42 m³/h nominal volume flow with substantially greater differential capability than the single-stage SV 5.90/1.
At 50 Hz the 0.37kW configuration provides maximum relative vacuum of -230 mbar and maximum positive pressure of +250 mbar. At 60 Hz the corresponding 0.44kW motor provides 50 m³/h, with maximum vacuum of -240 mbar and maximum pressure of +225 mbar.
The double-stage arrangement makes this configuration particularly useful where stronger suction or discharge pressure is required from a relatively small side channel blower.

Compact Blower with Double-Stage Differential
The Becker SV 5.90/2 takes a different approach to the single-stage SV 5.90/1. Rather than prioritising free-air volume, the process air passes through two successive side channel stages to generate considerably greater vacuum or positive-pressure differential.
At 50 Hz, nominal capacity is 40 m³/h with maximum relative vacuum of -230 mbar and maximum positive pressure of +250 mbar. This gives the compact blower useful performance for applications where the connected system presents greater resistance.
The rotating impeller transfers energy into the process air without contacting the blower housing. Passing the air through the second compression stage increases the achievable differential without introducing rubbing compression elements.
The compression chamber operates without lubricating oil. This provides oil-free process airflow and makes the SV 5.90/2 suitable for industrial machinery where clean air and relatively straightforward maintenance are desirable.
Nominal capacity should not be confused with airflow at the working point. The actual volume available within an installation depends on the vacuum or pressure differential generated by pipework, filters and the process itself.
Becker SV 5.90/2 Technical Specifications
The SV 5.90/2 uses a 0.37kW motor at 50 Hz and corresponding 0.44kW rating at 60 Hz. Nominal volume flow is 42 m³/h at 50 Hz and 50 m³/h at 60 Hz.
| Frequency | Nominal Capacity | Maximum Vacuum | Maximum Pressure | Motor Power |
| 50 Hz | 40 m³/h | -230 mbar | +250 mbar | 0.37kW |
| 60 Hz | 50 m³/h | -240 mbar | +225 mbar | 0.44kW |
Vacuum and pressure figures are relative.
Key Features of the Becker SV 5.90/2
Double-Stage Design
Two successive side channel stages allow considerably greater differential than the single-stage SV 5.90/1.
-230 mbar Vacuum
Strong suction performance for a compact 0.37kW side channel blower.
+250 mbar Pressure
Useful positive-pressure differential for blowing, conveying and process-air applications.
Compact 42 m³/h Unit
Provides a useful combination of moderate airflow and relatively high differential from a small blower.
Oil-Free Process Air
No lubricating oil is required within the compression chamber.
Non-Contact Operation
The impeller does not rely on rubbing compression elements to generate airflow and differential.
SV 5.90/2 Industrial Applications
The higher differential capability of the SV 5.90/2 makes it particularly useful on compact machinery where the air system presents greater resistance.
› Vacuum lifting and handling
› Vacuum holding and fixing
› Packaging machinery
› Printing and paper equipment
› Pneumatic conveying
› Waste water aeration
› Drying and process air
› General industrial machinery
Becker SV 5.90/2 Supply and Application Support
Vacuum Pumps UK can assist with Becker SV 5.90/2 requirements for industrial machinery and vacuum or pressure installations.
For an existing blower, send us photographs of the complete Becker and motor nameplates. The exact model designation is particularly important when distinguishing between the /1 and /2 configurations.
For a new application, provide both the required airflow and the normal working vacuum or pressure. The SV 5.90/2 offers substantially greater differential than the SV 5.90/1 but at a lower nominal airflow, so the correct selection depends on the actual system duty.
Accessories for Becker SV 5.90/2 Systems
Inlet Filters
Correct filtration helps protect the blower while avoiding unnecessary inlet restriction.
Vacuum Relief Valves
Vacuum relief can protect the blower if suction-side restriction increases excessively.
Pressure Relief Valves
Pressure relief helps control maximum differential if the discharge becomes restricted.
Installation Accessories
Correctly sized pipework and suitable connection components help minimise unnecessary system losses.
Becker SV 5.90/2 Service, Repair and Spare Parts
Although the SV 5.90/2 uses non-contact compression, the condition of the motor, bearings, impeller and connected system remains important to reliable operation.
Blocked filtration, restricted pipework or changes to the process can alter the operating differential and should be checked alongside the blower when investigating reduced performance or excessive temperature.
Blower Service
Technical support for Becker blower maintenance and performance problems.
Blower Repair
Workshop inspection and repair assessment for Becker SV side channel blowers.
Spare Parts
Becker replacement parts and filters are available through our sister company VacAir Superstore.
Becker SV 5.90/2 Frequently Asked Questions
What airflow does the Becker SV 5.90/2 provide?
Nominal volume flow is 40 m³/h at 50 Hz and 50 m³/h at 60 Hz.
What maximum vacuum does it provide?
Maximum relative vacuum is -230 mbar at 50 Hz and -240 mbar at 60 Hz.
What is the maximum positive pressure?
Maximum relative pressure is +250 mbar at 50 Hz and +225 mbar at 60 Hz.
What motor power does the SV 5.90/2 use?
The motor rating is 0.37kW at 50 Hz and 0.44kW at 60 Hz.
What is the difference between SV 5.90/1 and SV 5.90/2?
