Becker SV5.300/1 4kW Side Channel Blower
The Becker SV5.300/1 is a higher-differential single-stage side channel blower delivering 325 m³/h nominal airflow from a 4kW motor.
At 50 Hz it provides maximum relative vacuum of -300 mbar and maximum positive pressure of +260 mbar. The stronger vacuum capability is particularly useful for suction systems, although the blower also provides substantial positive-pressure performance.
The SV5.300/1 generates continuous oil-free airflow using the non-contact side channel principle, making it suitable for demanding industrial machinery and process-air applications.

Higher Vacuum Differential with 325 m³/h Airflow
The SV5.300/1 combines increased airflow with a considerably stronger vacuum differential than many smaller single-stage blowers. Its 325 m³/h nominal capacity allows a substantial volume of air to be moved, while maximum relative vacuum reaches -300 mbar.
Positive-pressure performance remains substantial at up to +260 mbar relative. This gives the SV5.300/1 the flexibility to operate in suction or blowing applications, with its performance profile particularly attractive where vacuum capability is the principal requirement.
Air entering the blower is accelerated by the rotating impeller and repeatedly returned into the side channel. Each circulation adds energy to the air, allowing the pressure differential to build progressively before discharge.
There is no requirement for lubricating oil within the process-air chamber and the impeller does not depend upon rubbing contact to generate compression. This provides clean, continuous airflow suitable for a wide variety of industrial equipment.
The maximum differential figures should not be interpreted as the normal operating point for every installation. Correct blower selection requires consideration of the required airflow at the intended vacuum or pressure, together with pipework and system resistance.

SV5.300/1 Performance Characteristics
325 m³/h Capacity
Substantial nominal airflow for industrial machines, handling systems and process equipment.
-300 mbar Vacuum
Provides significantly stronger suction differential for more demanding industrial vacuum applications.
+260 mbar Pressure
Strong positive-pressure capability for conveying, blowing and other process-air duties.
4kW Motor
Provides the power required for the higher airflow and differential capability of this SV5 configuration.
Dry Process Air
Oil is not required within the side channel compression chamber, providing oil-free process airflow.
Continuous Operation
Regenerative side channel compression provides a smooth and continuous flow rather than a pulsating air supply.
Industrial Applications for the SV5.300/1
The combination of higher airflow and -300 mbar maximum vacuum makes the SV5.300/1 particularly relevant to machinery requiring stronger suction performance while still retaining useful pressure-side capability.
› Vacuum lifting and handling systems
› Printing and paper machinery
› Packaging and production equipment
› Material hold-down applications
› Pneumatic conveying and transport
› Industrial drying systems
› Cooling and water aeration
› General process vacuum and pressure
Selecting or Replacing an SV5.300/1
An existing Becker SV5.300/1 can often be identified from the blower and motor nameplates. Providing these details helps establish the installed configuration and electrical specification when sourcing a replacement.
For new installations, nominal airflow alone should not determine blower selection. The required airflow at the actual operating vacuum or pressure is more important, particularly on systems where filters, long pipe runs, small-bore pipework or process equipment create significant resistance.
Vacuum Pumps UK can help review the duty and identify an appropriate Becker side channel blower for new or replacement installations.
Becker SV5.300/1 Accessories
Accessories should be selected according to whether the SV5.300/1 is being operated on vacuum or positive pressure and the conditions within the connected system.
Air Filtration
Suitable inlet filtration helps protect the blower from dust and airborne process contamination.
Vacuum Relief Valves
Vacuum regulation can help prevent excessive differential where inlet restriction increases.
Pressure Relief Valves
Relief protection can limit discharge pressure where the blower is used on positive-pressure duty.
System Connections
Silencers, flexible connectors, non-return valves and pipework components can assist with installation.
Becker SV5.300/1 Service, Repair and Spare Parts
Reduced performance from an SV5.300/1 does not necessarily mean that the blower itself is the only cause. Blocked filters, altered pipework, restrictions and process changes can affect the operating point, while bearing or motor condition can produce increased noise or temperature.
Vacuum Pumps UK can assist with assessment, servicing and workshop repair of Becker side channel blowers and help determine whether repair or replacement is appropriate.
Service Support
