Becker SV 200/2 1.5 kW Side Channel Blower
The Becker SV 200/2 1.5 kW is a high-differential double-stage side channel blower providing 90 m³/h nominal capacity with particularly strong positive-pressure performance.
At 50 Hz the blower is rated to -330 mbar relative vacuum and +410 mbar positive pressure. At 60 Hz the corresponding 1.8 kW motor increases nominal volume flow to 110 m³/h while maximum differential rises to -350 mbar vacuum and +430 mbar pressure.
The 1.5 kW configuration is especially useful where a relatively modest volume of air must be moved through a restrictive pressure system, while retaining substantial vacuum capability for suction applications.

High Pressure Differential with 90 m³/h Capacity
The SV 200/2 1.5 kW uses the double-stage side channel principle to produce a high pressure differential from a blower with a nominal 50 Hz volume flow of 90 m³/h. Its +410 mbar positive-pressure rating is a defining characteristic of this particular motor configuration.
This makes the blower particularly relevant to pneumatic conveying, aeration, drying and process-air systems where resistance through pipework or equipment requires considerably more pressure than a conventional low-pressure fan can provide.
The blower is equally capable of operating on the suction side. Maximum relative vacuum is -330 mbar at 50 Hz, while at 60 Hz the corresponding 1.8 kW configuration reaches -350 mbar. It can therefore serve vacuum handling and industrial suction duties as well as pressure applications.
Within the double-stage construction, gas passes through one side channel and is then redirected through the second impeller side. Repeated acceleration of the gas builds the required differential without physical contact between the impeller and compression chamber.
The process-air path requires no lubricating oil. Combined with the non-contact operating principle, this provides a clean airflow solution for machinery and processes requiring vacuum or pressure without oil being introduced into the compression chamber.
Becker SV 200/2 1.5 kW Technical Specifications
The 0 Hz performance of this configuration is particularly notable. With the corresponding 1.5 kW motor, nominal capacity increases to 90 m³/h and maximum differential reaches -330 mbar vacuum or +410 mbar positive pressure.
| Frequency | Nominal Capacity | Maximum Vacuum | Maximum Pressure | Motor Power | Weight |
| 50 Hz | 90 m³/h | -330 mbar | +410 mbar | 1.5 kW | 28.5 kg |
| 60 Hz | 110 m³/h | -350 mbar | +430 mbar | 1.8 kW | 28.5 kg |

Key Features of the SV 200/2 1.5 kW
+410 mbar at 50 Hz
Strong positive-pressure capability makes this configuration particularly suitable for demanding blowing and conveying systems.
Double-Stage Compression
Two successive side channel stages develop a higher differential than would normally be available from a comparable single-stage arrangement.
Vacuum and Pressure Duty
The same blower principle can be used for suction applications or as a positive-pressure source depending on the installation.
Oil-Free Compression
The process-air chamber does not require lubricating oil, avoiding oil introduction into the airflow.
Non-Contact Impeller
Aerodynamic compression avoids rubbing compression elements within the air chamber and contributes to low routine maintenance.
110 m³/h at 60 Hz
The corresponding 60 Hz configuration increases nominal volume flow while also providing up to +430 mbar positive pressure.
Demanding Pressure and Vacuum Applications
The combination of 90 m³/h nominal capacity and +410 mbar pressure at 50 Hz gives the 1.5 kW SV 200/2 a particularly useful performance profile for systems where high differential is required without very high airflow.

SV 200/2 1.5 kW Supply and Application Support
Vacuum Pumps UK can assist with Becker SV 200/2 1.5 kW blower supply for existing equipment, replacement requirements and new industrial vacuum or pressure installations.
If the blower is being replaced like-for-like, photographs of the complete nameplate and motor details help us identify the exact configuration. This is particularly useful because different motor versions can share the SV 200/2 model designation while offering different maximum pressure performance.
For process selection, the most useful information is the required airflow at the actual working pressure or vacuum. A system requiring 90 m³/h at a significant differential is a different duty from one requiring 90 m³/h close to free flow.
Our team can also discuss filtration, relief valves and installation arrangements where these form part of the blower requirement.
Accessories for High-Differential SV 200/2 Systems
Higher pressure differential makes good system design especially important. Unnecessary restriction can move the blower away from its intended operating point, so filtration and pipework should be appropriately sized for the required airflow.
Inlet Filters
Suitable filtration protects the blower from airborne contamination while avoiding excessive inlet pressure loss.
Vacuum Relief Valves
Vacuum relief can limit suction differential if the process or inlet system becomes excessively restrictive.
Pressure Relief Valves
Relief protection is important on high-pressure duties where a blocked discharge could increase blower differential.
Installation Accessories
Flexible connectors, valves and correctly sized pipework can help create a reliable complete blower installation.
Becker SV 200/2 1.5 kW Service, Repair and Spare Parts
The SV 200/2 uses non-contact side channel compression, but blower condition and the connected system both influence its performance. Motor condition, bearings, impeller clearance, filtration and pipework resistance should all be considered when investigating an operating problem.
This is especially relevant on higher-differential duties. A restricted filter or partially obstructed pipe can increase load and temperature even when the blower itself has no internal mechanical fault.
Vacuum Pumps UK can assist with Becker side channel blower servicing, fault investigation and workshop repair.
Blower Service
Technical support for Becker SV maintenance, operating problems and performance checks.
Blower Repair
Workshop investigation of noisy, damaged, overheating or under-performing side channel blowers.
Spare Parts
Becker spare parts and replacement filtration are available through our sister company VacAir Superstore.
Becker SV 200/2 1.5 kW Frequently Asked Questions
What is the capacity of the Becker SV 200/2 1.5 kW?
Nominal volume flow is 90 m³/h at 50 Hz and 110 m³/h at 60 Hz.
What maximum pressure can the 1.5 kW SV 200/2 produce?
Maximum positive pressure is +410 mbar at 50 Hz. At 60 Hz, with the corresponding 1.8 kW motor rating, maximum pressure is +430 mbar.
What is the maximum vacuum?
The blower provides maximum relative vacuum of -330 mbar at 50 Hz and -350 mbar at 60 Hz.
How does this differ from the SV 200/2 1.1 kW?
Both configurations have the same nominal 90 m³/h capacity at 50 Hz and both are rated to -330 mbar maximum vacuum. The principal difference is positive-pressure capability: the 1.5 kW version increases the 50 Hz maximum from +300 mbar to +410 mbar.
Why use a double-stage side channel blower?
A double-stage design redirects the airflow through a second side channel stage, allowing greater vacuum or pressure differential to be developed where the application has higher resistance.
Is the compression chamber oil-free?
Yes. The side channel compression chamber operates without lubricating oil and without rubbing vanes in the process-air path.
Can Vacuum Pumps UK help with an existing Becker SV 200/2?
Yes. Send us the blower and motor nameplate details and we can assist with identification, replacement supply, servicing, repair and system accessories.
