Becker SV5.430/1 4kW Side Channel Blower
The Becker SV5.430/1 is a single-stage side channel blower designed to provide a substantial volume of oil-free process air, with 460 m³/h nominal capacity from a 4kW motor.
At 50 Hz, maximum relative vacuum is -200 mbar and maximum positive pressure is +200 mbar. The equal vacuum and pressure figures give the SV5.430/1 balanced performance on either side of the blower.
Its combination of higher airflow and moderate differential makes this model particularly relevant to industrial processes requiring continuous air movement rather than exceptionally high vacuum or discharge pressure.

High Airflow with Balanced Vacuum and Pressure
With a nominal capacity of 460 m³/h, the Becker SV5.430/1 moves a considerably larger volume of air than the smaller SV5 single-stage models. This makes it appropriate for machinery and process systems where airflow demand is a major part of blower selection.
The performance profile is evenly balanced between suction and discharge operation, with maximum relative vacuum of -200 mbar and maximum relative positive pressure of +200 mbar. It can therefore be considered for vacuum or pressure duties without a strong bias towards either operating mode.
Air is accelerated by the rotating impeller and circulated through the side channel. Repeated transfer of energy progressively creates the pressure differential while maintaining a continuous flow through the blower.
The impeller operates without rubbing contact with the blower housing, and lubricating oil is not required within the process-air chamber. This enables the SV5.430/1 to provide oil-free air for industrial machinery and process applications.
When selecting a blower, nominal free-air capacity should be considered together with the working vacuum or pressure. Filters, pipe dimensions, bends, valves and process restrictions influence system resistance and therefore the actual airflow available at the operating point.
Becker SV5.430/1 Technical Data

SV5.430/1 Performance Characteristics
460 m³/h Capacity
Higher nominal airflow provides substantial air movement for larger industrial machinery and process systems.
-200 mbar Vacuum
Provides useful suction differential for vacuum transport, handling and machine-air applications.
+200 mbar Pressure
Matching pressure capability suits blowing, conveying, aeration and other positive-pressure duties.
4kW Motor
Combines the 460 m³/h nominal capacity with a 4kW motor configuration at 50 Hz.
Oil-Free Airflow
No lubricating oil is required in the process-air chamber during normal side channel operation.
Non-Contact Principle
Regenerative compression produces continuous airflow without relying on rubbing compression elements.
Typical SV5.430/1 Applications
The 460 m³/h airflow capacity makes the SV5.430/1 particularly useful where a larger volume of air must be supplied or extracted continuously across an industrial process.
› Pneumatic conveying and material transport
› Printing and paper machinery
› Packaging and production equipment
› Vacuum handling and lifting
› Industrial drying systems
› Cooling and air circulation
› Aeration and blowing systems
› General process vacuum and pressure
Replacing a Becker SV5.430/1
For an existing SV5.430/1 installation, the blower and motor nameplate information should be checked when selecting a replacement. This helps confirm the installed model, motor rating and electrical configuration.
The operating conditions should also be considered. Changes to pipework, filtration or machinery can alter the system resistance and therefore the airflow required from the replacement blower.
Vacuum Pumps UK can assist with identification of an existing Becker blower and review the application requirements for replacement or new installations.
Becker SV5.430/1 Blower Accessories
Correct filtration, regulation and connection components help protect the blower and integrate it effectively with the connected vacuum or pressure system.
Inlet Filtration
Filters can help prevent dust and airborne contamination from entering the blower and process-air path.
Vacuum Regulation
Vacuum relief valves can limit excessive suction differential caused by increased system restriction.
Pressure Protection
Pressure relief devices help control the maximum differential when operating on positive pressure.
Installation Accessories
Silencers, flexible connectors, non-return valves and other components can be selected to suit the installation.
Becker SV5.430/1 Service, Repair and Spare Parts
Although side channel blowers have relatively low routine maintenance requirements, an SV5.430/1 that has accumulated substantial operating hours can eventually require attention to bearings, motor components, filtration or other parts. Changes in noise, temperature or airflow should be investigated rather than assumed to be normal deterioration.
Vacuum Pumps UK can assist with inspection, fault diagnosis, service and workshop repair requirements for Becker SV side channel blowers.
