DVP TPL Double Parallel-Stage Side Channel Blowers
DVP TPL double parallel-stage side channel blowers are engineered for industrial vacuum and pressure systems requiring very high airflow together with dependable differential pressure.
By arranging two regenerative stages in parallel, the TPL range increases total air-moving capacity rather than using the second stage solely to intensify pressure. This makes it particularly suitable for large process systems, centralised installations and machinery with substantial flow demand.

High-Capacity Oil-Free Airflow for Large Industrial Systems
The DVP TPL range is designed for duties where the principal requirement is a large volume of clean air, but where useful vacuum or positive pressure must still be maintained. Instead of routing the air sequentially through two stages, the parallel configuration divides and recombines the flow to increase overall capacity.
This operating arrangement allows TPL blowers to serve systems with higher air demand than a conventional single-stage unit of similar construction. It also provides a compact alternative to installing multiple separate blowers where one correctly selected machine can satisfy the full process requirement.
The same blower may be used for suction or pressure duty, making the range suitable for machine builders, central vacuum designers and process engineers requiring high-volume, continuous and oil-free airflow.
When Is a Parallel-Stage Blower the Right Choice?
A parallel-stage blower is generally selected where airflow demand is too high for a smaller single-stage or double-stage model, but the system does not require the deepest vacuum obtainable from a series-connected multi-stage arrangement.
The TPL design is particularly useful for large centralised systems, high-volume aeration, process air movement and machinery serving several suction or pressure points simultaneously.
Where maximum pressure differential is the primary requirement, a conventional double-stage or triple-stage blower may be more appropriate. Where flow volume is the dominant factor, the TPL range provides a strong balance of capacity, pressure and installation efficiency.
Key Benefits of DVP TPL Parallel-Stage Blowers
Very High Airflow
Parallel regenerative stages increase total flow capacity for large machinery and process systems.
Oil-Free Operation
No oil is used in the compression path, helping prevent contamination of the conveyed air or gas.
Vacuum or Pressure Duty
The blower can be connected for suction or positive pressure according to the process requirement.
Low Routine Maintenance
The non-contact operating principle avoids internal vane wear and minimises scheduled servicing.
Stable Continuous Airflow
Regenerative compression produces smooth, low-pulsation flow for stable industrial operation.
IE3 Three-Phase Motors
High-efficiency three-phase motors support reliable operation in demanding industrial installations.
Typical Applications for TPL Blowers
DVP TPL parallel-stage blowers are intended for systems requiring substantial air volume, continuous operation and clean vacuum or pressure.
Central Vacuum Systems
Supplying high-volume suction through manifolds and pipework serving multiple production machines or operating points.
Pneumatic Conveying
Moving powders, granules and lightweight materials where a large flow of conveying air is required.
Wastewater & Process Aeration
Delivering high air volumes to diffusers, treatment tanks, process vessels and biological systems.
Industrial Drying & Cooling
Providing continuous high-volume airflow for surface drying, cooling, air knives and moisture removal.
Printing & Paper Processing
Supporting sheet control, transport, extraction and blow-off systems on large printing or converting equipment.
Large Packaging Lines
Supplying several vacuum or pressure functions across automated packaging and materials-handling systems.
TPL and TPLV Configurations
The standard TPL models use the conventional port arrangement for connection into horizontal pipework and machine systems.
TPLV models provide a vertically mounted suction inlet, which can simplify installation where space, pipe orientation or machine layout makes a vertical connection more practical.
The correct arrangement should be selected with reference to the installation drawing, available space and the direction of the connected pipework.
Vacuum and Pressure Performance
For vacuum operation, the process is connected to the blower inlet. For pressure operation, the outlet supplies compressed air to the system.
The achievable airflow changes as the differential pressure rises. A model rated at a high nominal capacity will deliver less flow once connected to restrictive pipework or a process operating at significant vacuum or pressure.
Model selection must therefore be based on the required airflow at the actual operating point, together with motor loading, system resistance, duty cycle and ambient conditions.

Selecting the Correct TPL Model
Selection should begin with the required airflow at the real operating vacuum or pressure, not the nominal free-air capacity alone.
Pipe length, pipe diameter, bends, filters, silencers, diffusers, valves and leakage all influence system resistance and therefore the final operating point.
Vacuum Pumps UK can review your application data and help identify the correct TPL or TPLV model, motor rating and accessory package.
Why Performance Curves Matter
Nominal capacity is measured under low-resistance conditions. As vacuum or delivery pressure increases, the available airflow falls and motor loading changes.
The relevant performance curve should be used to confirm that the required duty lies within the safe continuous operating area.
Allowing a sensible performance margin can help control temperature, current draw and long-term operating stress.
Accessories and System Protection
Inlet Filters
Protect the blower from dust, debris and process contamination entering through the suction line.
Relief Valves
Limit excessive vacuum or pressure if flow is restricted or a process valve closes unexpectedly.
Silencers
Reduce inlet or discharge noise where lower sound levels are required around equipment or personnel.
Flexible Connectors
Help isolate vibration and simplify connection between the blower and rigid process pipework.
Installation Considerations
Install the blower on a stable base with sufficient ventilation around the motor and blower casing. Large-volume systems require adequately sized pipework to avoid unnecessary pressure losses.
Pipework should be independently supported so that its weight is not carried by the blower connections. Three-phase rotation, electrical protection and motor connection must be checked before commissioning.
Ambient temperature, air inlet temperature, altitude, duty cycle and gas composition should all be considered during system design.
Maintenance and Service Support
TPL blowers require relatively little routine maintenance because their impellers operate without contact and no oil is used within the air path.
Routine attention should include checking inlet filters, keeping cooling passages clear, inspecting pipework and monitoring the blower for abnormal noise, vibration, temperature or motor current.

Frequently Asked Questions
What does double parallel stage mean?
It means two regenerative blower stages are arranged to increase total airflow capacity rather than passing the full air stream through one stage and then the next.
How does a TPL differ from a TDL blower?
A TDL double-stage blower is generally selected to achieve greater differential pressure. A TPL parallel-stage blower is designed to provide substantially more airflow while retaining useful vacuum and pressure performance.
What is the difference between TPL and TPLV?
TPLV models use a vertically mounted suction inlet, which may be more convenient where machine layout or pipework orientation makes a vertical connection preferable.
Are TPL blowers oil free?
Yes. There is no oil in the compression path, so the conveyed air or gas is not contaminated by lubricating oil from the blower chamber.
What information is needed for model selection?
Provide the required airflow at the operating vacuum or pressure, electrical frequency, duty cycle, ambient conditions, gas details and information about the connected pipework or process.
