Becker SV5.490/1 5.5kW Side Channel Blower
The Becker SV5.490/1 combines 480 m³/h nominal capacity with strong differential performance from a single-stage side channel blower.
At 50 Hz, the 5.5kW configuration provides maximum relative vacuum of -300 mbar and maximum positive pressure of +280 mbar. This combination allows the blower to move a high volume of air while working against considerably greater system resistance than lower-differential models.
The non-contact regenerative compression principle provides continuous oil-free process airflow for industrial machinery, conveying equipment and vacuum or pressure systems.

High Airflow and Strong Operating Differential
The SV5.490/1 provides a different performance balance from the SV5.430/1. Although nominal airflow increases only to 480 m³/h, the available differential rises considerably, reaching -300 mbar relative vacuum and +280 mbar relative pressure.
This makes the SV5.490/1 suitable for applications where the blower must not only move a significant volume of air but also overcome appreciable restriction within the connected machinery, pipework or process.
During operation, the impeller repeatedly accelerates air through the annular side channel. Energy is progressively transferred to the air as it circulates around the housing, allowing differential pressure to develop before the air reaches the outlet.
The process does not require lubricating oil within the compression chamber, and there is no rubbing contact between the impeller and housing. The result is continuous oil-free airflow suitable for many industrial vacuum and pressure duties.
Correct sizing should always consider the required operating point rather than comparing nominal capacity alone. A blower required to provide airflow at -250 mbar, for example, is operating under very different conditions from one moving air through a relatively unrestricted system.

SV5.490/1 Replacement and Application Support
When replacing an existing SV5.490/1, the complete blower and motor nameplate information should be checked. Electrical details and the original application can be important when confirming the appropriate replacement configuration.
Where the blower is being selected for a new process, the required airflow should be considered at the actual operating differential. Pipework losses, filters, silencers, valves and process restrictions can all influence the blower operating point.
Vacuum Pumps UK can assist with Becker blower identification, application review and replacement selection.
Becker SV5.490/1 Accessories
The higher differential capability of the SV5.490/1 makes correct filtration and relief protection particularly important when the blower is integrated into a restricted vacuum or pressure system.
Inlet Filters
Correct filtration protects the blower from dust and contamination entering with the process air.
Vacuum Relief
Vacuum regulation can limit excessive suction differential if inlet resistance increases unexpectedly.
Pressure Relief
Pressure protection can control maximum discharge differential in positive-pressure applications.
System Accessories
Silencers, flexible connections, non-return valves and pipework components can complete the installation.
Becker SV5.490/1 Service, Repair and Spare Parts
Loss of airflow or differential on an SV5.490/1 can result from blower condition or from changes elsewhere in the system. Filters, pipe restrictions and process conditions should be considered alongside bearing, motor and blower condition when investigating performance problems.
Vacuum Pumps UK can assist with inspection, fault diagnosis, servicing and workshop repair of Becker side channel blowers.
