Becker SV8.400/1 5.5kW Side Channel Blower
The Becker SV8.400/1 is a higher-capacity single-stage side channel blower providing 410 m³/h nominal airflow from a 5.5kW motor.
Maximum relative vacuum is -300 mbar and maximum positive pressure is +330 mbar at 50 Hz. Combining substantial airflow with strong differential on both sides of the blower gives the SV8.400/1 useful capability for demanding industrial vacuum and pressure applications.
The non-contact regenerative design generates continuous oil-free process air for conveying, handling, drying, aeration and production systems.

410 m³/h with High Vacuum and Pressure Differential
The Becker SV8.400/1 combines a nominal capacity of 410 m³/h with considerably stronger differential capability than many lower-powered single-stage blower configurations.
On vacuum duty it can operate up to -300 mbar relative vacuum, while positive-pressure performance reaches +330 mbar. The slightly greater pressure capability makes the blower particularly useful for applications requiring substantial air volume to be delivered against process or pipework resistance, while still providing strong performance when used for suction.
Air is moved by a rapidly rotating impeller within the side channel housing. The air receives repeated energy input as it circulates through the channel, progressively developing the pressure difference required by the connected system.
The impeller operates without rubbing contact against the housing and lubricating oil is not required in the compression chamber. This provides an oil-free process-air path and avoids the routine replacement of compression vanes.
At this 410 m³/h capacity, system design becomes especially important. Pipe bore, filter sizing, bends, valves and restrictions should be appropriate for the required airflow to avoid unnecessary pressure losses and excessive blower differential.

SV8.400/1 Performance and Design
410 m³/h Airflow
Substantial nominal air volume for larger machinery, conveying installations and industrial process systems.
-300 mbar Vacuum
Strong single-stage suction capability for higher-differential industrial vacuum applications.
+330 mbar Pressure
Provides substantial positive-pressure capability for conveying, aeration and process blowing.
5.5kW Motor
Supports the combination of high airflow and strong operating differential available from the SV8.400/1.
Oil-Free Compression
No lubricating oil is required within the process-air chamber during normal blower operation.
Continuous Air Supply
Regenerative side channel operation provides a smooth continuous airflow for industrial processes.
Industrial Uses for the SV8.400/1
The combination of 410 m³/h nominal airflow, -300 mbar vacuum and +330 mbar positive pressure gives the SV8.400/1 useful capability for larger industrial systems requiring both significant airflow and operating differential.

Becker SV8.400/1 Supply and Replacement
Vacuum Pumps UK can assist with SV8.400/1 requirements for replacement machinery and new industrial vacuum or pressure installations.
For an existing unit, send us the information from the blower and motor nameplates together with photographs where possible. Details of the connected process can help when confirming whether the replacement should reproduce the original operating duty.
For new applications, the 410 m³/h nominal capacity needs to be considered alongside the required working vacuum or positive pressure. At higher differentials, the complete system resistance and expected operating airflow become particularly important to correct blower selection.
Becker SV8.400/1 Accessories
The higher airflow and differential capability of the SV8.400/1 make correctly sized accessories important. Filtration and pipework should permit the required airflow, while relief equipment can help prevent excessive vacuum or pressure.
Inlet Filtration
Correctly sized filter housings and elements help protect the blower without introducing unnecessary inlet restriction.
Vacuum Relief
Vacuum relief can protect the SV8.400/1 where suction restriction could otherwise exceed the intended operating differential.
Pressure Relief
Pressure relief equipment can limit discharge differential and provide protection on positive-pressure systems.
Installation Components
Silencers, non-return valves, flexible connections and appropriately sized pipework components can be selected for the installation.
Becker SV8.400/1 Service, Repair and Spare Parts
Reliable SV8.400/1 operation depends not only on the blower itself but also on the condition of the connected air system. Restricted filtration, undersized or blocked pipework and changes to the process can increase operating differential and temperature.
Mechanical noise, vibration or deterioration in performance may also indicate bearing or motor issues requiring investigation. Vacuum Pumps UK can assist with fault diagnosis, servicing and workshop repair of Becker side channel blowers.
Blower Service
Maintenance and technical support for Becker side channel blowers used on industrial vacuum and pressure systems.
Blower Repair
Workshop assessment for bearing wear, abnormal noise, motor faults, damage and reduced blower performance.
Spare Parts
Replacement filters and Becker spare parts are available through our sister company VacAir Superstore.
