Explore the DVP Side Channel Blower Range

DVP TSL Single-Stage Side Channel Blowers

The DVP TSL single-stage range is designed for applications requiring high airflow at moderate vacuum or pressure. Unlike positive-displacement vacuum pumps, a side channel blower moves air using a high-speed, non-contact impeller.

The impeller transfers energy to the air repeatedly as it travels around the annular side channel. This regenerative action increases the pressure difference between the inlet and outlet while maintaining smooth, pulsation-free airflow.

Because there is no oil within the compression chamber and no internal contact between the impeller and housing, TSL blowers provide clean operation with very little routine maintenance.

The same blower can be connected for suction or pressure duty, making the range suitable for machine builders, production plants and process engineers requiring a compact and versatile air-moving solution.

When Is a Single-Stage Blower the Right Choice?

A single-stage side channel blower is generally selected where the application requires relatively high airflow but does not need the greater differential pressure produced by multi-stage designs.

Compared with double-stage or triple-stage arrangements, single-stage models usually provide more airflow for a given frame size and motor power, but at a lower maximum vacuum or pressure.

They are particularly well suited to aeration, air knives, cooling, drying, pneumatic conveying, printing, paper handling, vacuum lifting and general machine automation.

Where the required pressure difference exceeds the capability of a single-stage unit, the double-stage, parallel-stage or triple-stage TSL ranges should be considered.

Key Benefits of DVP TSL Blowers

Typical Industrial Applications

DVP TSL single-stage blowers are used across a wide range of industries where clean air, high volume and moderate vacuum or pressure are required.

Vacuum and Pressure Operation

A side channel blower has an inlet and an outlet. Connecting the process to the inlet produces vacuum, while connecting it to the outlet provides positive pressure.

The maximum allowable vacuum and pressure differ between models and motor ratings. Some units are optimised for airflow, while higher-powered versions within the same frame can achieve a greater differential pressure.

Operating outside the permitted performance envelope can increase motor current, discharge temperature and mechanical stress.

The specification table below should therefore be used together with the application flow requirement, system resistance and expected operating point.

Single-Stage TSL Model Specification Table

Choosing the correct TSL model requires matching the required flow rate, motor power, vacuum and pressure to the actual operating conditions.

How to Select the Correct TSL Model

Why Performance Curves Matter

The maximum airflow in the table is measured close to free-air conditions. As vacuum or pressure increases, the available airflow changes.

The operating point is created where the blower performance curve intersects the resistance curve of the connected system.

Pipe diameter, hose length, filters, valves, diffusers, nozzles and process restrictions all affect this resistance.

For accurate selection, Vacuum Pumps UK can review the DVP performance curve against the expected system conditions.

Side Channel Blower Accessories

Correct accessories protect the blower, control the operating point and reduce noise within the installation.

Installation Considerations

The blower should be installed on a stable surface with adequate space for cooling airflow and maintenance access.

Pipework should be correctly sized to limit pressure loss. Undersized pipe, sharp bends, blocked filters and restrictive fittings can move the operating point beyond the safe performance range.

The inlet air should be clean and within the temperature limits stated for the selected model. Suitable filtration should be used where dust or process debris may be present.

Relief protection should be installed where valves, blocked diffusers or process changes could cause excessive vacuum or pressure.

Electrical protection should be selected to suit the motor rating and starting characteristics, and installation should be completed by a competent person.

Maintenance and Service Life

TSL side channel blowers do not use carbon vanes, oil separators or oil within the pumping chamber.

Routine maintenance is therefore generally limited to keeping the cooling surfaces clean, inspecting inlet filters, checking pipework and monitoring noise, vibration and motor current.

Blocked filters or restricted airflow can increase operating temperature and motor load, so filters should be checked at intervals appropriate to the environment.

Vacuum Pumps UK can supply replacement filters, relief valves, silencers and other accessories, while inspection and repair support is available through our sister company, VacAir Superstore.

DVP Single-Stage Side Channel Blower FAQs

What is a single-stage side channel blower?

It is an oil-free regenerative blower with one impeller stage, designed to produce high airflow at moderate vacuum or pressure.

Can a TSL blower produce both vacuum and pressure?

Yes. Connecting the process to the inlet creates vacuum, while using the outlet provides positive pressure.

Does a side channel blower use oil?

No oil is used within the compression chamber, so the conveyed air remains free from pump oil contamination.

What is the difference between single-stage and double-stage blowers?

A single-stage blower generally provides higher airflow at lower differential pressure. A double-stage blower provides greater vacuum or pressure but usually less airflow for a comparable frame size.

Can a side channel blower run continuously?

Many models are suitable for continuous duty when correctly selected, installed and operated within the permitted performance range.

Why is a relief valve important?

A relief valve protects the blower if a pipe, valve, filter or process restriction causes excessive vacuum or pressure.

Can the airflow be controlled with an inverter?

Selected three-phase models may be used with a suitable frequency inverter, subject to the motor, cooling and permitted speed range.

What information is needed to select a blower?

Useful information includes required airflow, vacuum or pressure, electrical supply, duty cycle, ambient conditions, pipework and the application.

Can Vacuum Pumps UK replace another manufacturer’s blower?

Yes. Send us the existing model, nameplate photograph, performance requirement and connection details so we can compare the nearest DVP alternative.

Does Vacuum Pumps UK provide service support?

Yes. Technical support is available through Vacuum Pumps UK, with workshop inspection and repair support through VacAir Superstore.
