Becker SV5.330/2 3kW Side Channel Blower
The Becker SV5.330/2 is a two-stage side channel blower providing 180 m³/h nominal airflow from a 3kW motor, with an evenly balanced performance for vacuum and pressure applications.
At 50 Hz, maximum relative vacuum is -330 mbar and maximum positive pressure is +330 mbar. The matching differential limits make this configuration suitable for machinery requiring useful airflow and similar performance whether operating on suction or pressure.
The regenerative two-stage compression system provides clean, oil-free process air without rubbing carbon vanes within the compression chamber.

Balanced Two-Stage Performance at 180 m³/h
The Becker SV5.330/2 provides a particularly even balance between airflow and differential. Its nominal capacity is 180 m³/h, while the maximum relative vacuum and maximum positive pressure are both rated at 330 mbar.
For industrial machinery this provides considerable flexibility. A blower may be required to draw air through a process on one installation and deliver air against resistance on another, and the SV5.330/2 offers closely matched capability in either operating direction.
The /2 designation identifies its two-stage arrangement. The regenerative side channel process transfers energy repeatedly into the moving air, with the successive stages enabling a greater overall pressure differential to be developed.
There is no rubbing contact between the impeller and compression chamber during normal operation and no lubricating oil is required in the process-air path.
The actual working airflow depends upon the system differential. Selection should therefore take account of the required 180 m³/h nominal capacity together with the vacuum or pressure at the intended operating point.

Becker SV5.330/2 Supply and Replacement
Vacuum Pumps UK can assist with SV5.330/2 replacement enquiries and with blower selection for new industrial vacuum and pressure systems.
When replacing an installed blower, the complete model and motor details should be checked. Photographs of the nameplate, blower and pipe connections can help establish the equipment fitted to the machine.
For new installations, system resistance should be considered alongside nominal airflow. Correct pipe sizing and suitable filtration and relief equipment can be important to achieving the intended operating performance.
Becker SV5.330/2 Accessories
Filtration, relief equipment and correctly sized system components can help protect the blower and maintain reliable vacuum or pressure performance.
Inlet Filtration
Helps protect the blower from airborne contamination entering the process-air path.
Vacuum Relief
Can limit excessive vacuum differential where inlet resistance varies during operation.
Pressure Relief
Can protect the blower if positive-pressure system resistance becomes excessive.
System Components
Silencers, valves, flexible connectors and associated components can be selected as required.
Becker SV5.330/2 Service, Repair and Spare Parts
Although the side channel compression process is non-contact, the blower still contains mechanical components and relies upon correct airflow through the system.
Bearing wear, motor condition, blocked filtration or excessive system restriction can cause increased temperature, abnormal noise, vibration or reduced performance.
Vacuum Pumps UK can assist with inspection, servicing, fault diagnosis and workshop repair of Becker side channel blowers.
