High-Volume Industrial Airflow from the SV 5.690/1

The Becker SV 5.690/1 moves into a higher airflow class within the single-stage SV range, providing 720 m³/h nominal capacity from its 11kW motor configuration. Importantly, that air volume is accompanied by a substantial operating differential, with maximum relative vacuum of -330 mbar and maximum positive pressure of +410 mbar.

This combination makes the blower relevant to larger industrial systems where simply moving a high volume of unrestricted air is not sufficient. Filters, long pipe runs, bends, valves, process equipment and material being conveyed can all create resistance. A blower serving these systems must provide the required airflow while also developing enough differential to overcome those losses.

On vacuum duties, the SV 5.690/1 can develop up to -330 mbar relative vacuum, giving it strong suction capability for handling, extraction and machine processes. When used as a pressure blower, the +410 mbar maximum positive pressure provides scope for conveying, aeration, drying and other applications where air must be delivered against appreciable back pressure.

The single-stage regenerative principle uses a rotating impeller within the side channel to repeatedly accelerate the air. As the air circulates around the channel, energy is transferred progressively before it leaves the blower, generating either vacuum at the inlet or positive pressure at the discharge.

This compression method does not require rubbing carbon vanes and does not rely on lubricating oil within the process-air chamber. For suitable applications, the SV 5.690/1 therefore provides a straightforward source of high-volume, oil-free industrial airflow.

Becker SV 5.690/1 Technical Specification

The 11kW SV 5.690/1 provides 720 m³/h nominal capacity at 50 Hz. Maximum relative vacuum is -330 mbar and maximum relative positive pressure is +410 mbar.

The 720 m³/h nominal capacity and the maximum vacuum and pressure figures describe different parts of the blower’s operating envelope. The blower does not simultaneously provide its free-air nominal capacity while operating at maximum differential.

As vacuum or positive pressure increases, available airflow changes according to the blower performance characteristic. For an application requiring both substantial airflow and differential, the relevant duty point should therefore be established rather than selecting a blower from maximum figures alone.

This becomes particularly important on higher-capacity installations. Pipework size and length, filters, valves, silencers, bends and process restrictions can create significant losses when handling hundreds of cubic metres of air per hour.

Applications for the Becker SV 5.690/1

With 720 m³/h nominal capacity, the SV 5.690/1 is particularly suited to larger machinery and process systems requiring significantly more airflow than smaller side channel blowers. Its vacuum and pressure range allows the same basic blower principle to be applied to both suction and positive-pressure duties.

For conveying and other resistance-dependent applications, the required air volume should be established at the intended operating pressure rather than from nominal capacity alone. Similarly, vacuum handling systems should be assessed against the airflow required at the actual suction differential.

Vacuum Pumps UK can assist with application selection where the required flow, vacuum or pressure is known, or where an existing blower is being replaced as part of a larger machine.

Replacing an Existing Becker SV 5.690/1

A higher-capacity blower such as the SV 5.690/1 may be closely matched to the characteristics of the machinery or process it serves. When replacing an installed unit, confirming the complete specification and operating duty is therefore preferable to choosing a replacement from nominal airflow alone.

Send Vacuum Pumps UK photographs of the complete blower together with clear images of the Becker identification plate and motor nameplate. Photographs showing the inlet and discharge connections, filters, valves and nearby pipework can provide additional useful information.

Tell us whether the blower operates on vacuum or positive pressure and what function it performs within the system. If you know the normal operating vacuum or pressure, required airflow or details of the material or process involved, include these with the enquiry.

This information helps us distinguish between simply identifying the original blower and selecting a unit capable of reproducing the actual operating duty of the machine.

Accessories and System Protection

Correct system design becomes increasingly important as blower airflow rises. At 720 m³/h, undersized pipework, restrictive filtration or inappropriate fittings can create significant pressure loss, increase the operating differential and affect the airflow available to the process.

Becker SV 5.690/1 FAQs

What is the capacity of the Becker SV 5.690/1?

The nominal capacity of this 50 Hz configuration is 720 m³/h.

What maximum vacuum does the SV 5.690/1 produce?

The listed maximum relative vacuum is -330 mbar.

What is the maximum positive pressure of the SV 5.690/1?

The listed maximum relative positive pressure is +410 mbar.

What motor power does this SV 5.690/1 use?

The configuration covered on this page uses an 11kW electric motor at 50 Hz.

Is the Becker SV 5.690/1 a single-stage blower?

Yes. The SV 5.690/1 uses a single regenerative side channel compression stage.

Can the SV 5.690/1 operate as either a vacuum or pressure blower?

Yes. Side channel blowers can be applied on the suction or discharge side of a suitable system. This SV 5.690/1 specification has listed maximum relative vacuum of -330 mbar and maximum positive pressure of +410 mbar.

Does the SV 5.690/1 use carbon vanes or oil for compression?

No. The regenerative side channel principle generates airflow without rubbing carbon vanes and does not require lubricating oil within the process-air chamber.

Why is the operating duty important when replacing an SV 5.690/1?

The 720 m³/h nominal capacity and maximum differential figures are not one simultaneous operating point. Establishing the required airflow at the actual working vacuum or pressure helps ensure the replacement is suitable for the process.

Can Vacuum Pumps UK help identify or replace an SV 5.690/1?

Yes. Send us photographs of the complete blower, Becker identification plate and motor nameplate together with information about the machine, application and known operating conditions.
