1. What is ErP Regulation (EU) 2024/1834?
European Regulation (EU) 2024/1834 is an implementing regulation based on the Ecodesign Directive 2009/125/EC. It establishes requirements for fans driven by an electric motor with an electrical input power of 125 W up to and including 500 kW, measured at the best efficiency point (BEP).
The regulation succeeds Regulation (EU) 327/2011. With the new legislation, the European Commission aims to further reduce the energy consumption of fans and encourage more efficient use of materials and resources.
The requirements do not only concern energy consumption. Greater attention is also given to the information manufacturers must provide about their products, performance at different rotational speeds, and opportunities for repair and reuse.
Official legislation
The original regulation was published on 4 July 2024. On 8 December 2025, Regulation (EU) 2025/481 was published. This amending regulation entered into force on 28 December 2025 and includes, among other things, clarifications regarding definitions, rotational speeds and transitional provisions.
For the current requirements, both regulations must be read together.
2. Timeline and implementation
The new legislation is being introduced in stages. These are the key dates:
| Date | What does this mean? |
|---|---|
| 4 July 2024 | Publication of Regulation (EU) 2024/1834 in the Official Journal of the European Union. |
| 24 July 2024 | Start of a transitional provision for certain models that meet the new requirements. |
| 8 December 2025 | Publication of amending Regulation (EU) 2025/2481. |
| 28 December 2025 | The amending regulation enters into force. |
| 24 July 2026 | The new ErP Regulation becomes applicable and replaces the previous Regulation (EU) 327/2011. |
| 24 July 2027 | Additional information on performance at different rotational speeds becomes mandatory for the fans concerned. The transitional arrangement for certain integrated fans also ends. |
| 24 July 2028 | Latest start date for the required availability of spare parts, depending on when the first unit of the relevant model was placed on the market. |
| 27 July 2030 | Deadline for the European Commission to review the regulation. |
| 24 July 2037 | End of the special transitional arrangement for certain replacement fans. |
Transitional arrangements apply to certain fans integrated into other products and to replacement fans. These arrangements are subject to conditions and do not automatically apply to all integrated or replacement fans.
3. Which fans are covered by the regulation?
The regulation applies to fans with an electrical input power of at least 125 W and no more than 500 kW at the best efficiency point (BEP).
This refers to the electrical input power of the fan at its best efficiency point, not solely to the rated motor power stated on the motor nameplate.
The legislation covers various types of fans, including:
- Axial fans: primarily move air in the direction of the impeller axis.
- Centrifugal fans: move air outwards through the impeller, in a direction largely perpendicular to the inlet direction. A distinction is made between forward-curved and backward-curved designs.
- Mixed-flow fans: combine characteristics of axial and centrifugal fans.
- Cross-flow fans: move air using a cylindrical impeller, with the airflow passing largely across the impeller.
- Jet fans: generate a directed airflow at high velocity.
The legislation can apply to both standalone fans and fans incorporated into other products.
Fans in combined products
Fans that form part of a larger product or combined installation may also fall within the scope of the regulation.
When determining which requirements apply, it is important to consider the fan configuration as placed on the market. The motor, impeller, housing and any speed control used may all be relevant.
Replacement fans
Replacement fans may also fall within the scope of the regulation. A special transitional arrangement applies until 24 July 2037 to certain replacement fans intended to replace an existing fan in another product.
This exemption only applies under specific conditions. Among other things, no suitable replacement fan that meets the new requirements must be available. In addition, the applicable previous efficiency requirements and the new information requirements must be met.
It is therefore important to assess whether a particular fan actually qualifies for this transitional arrangement when replacing an existing fan.
4. Which fans are excluded?
Not every fan falls within the scope of Regulation (EU) 2024/1834. The legislation includes several exemptions relating to the fan type, power rating and intended application.
The main exemption categories are:
| Category | Explanation |
|---|---|
| Motor cooling fans | Impeller blades mounted directly on the motor shaft and intended exclusively to cool the electric motor itself. |
| Washing machines and washer-dryers | Fans integrated into certain appliances with a maximum electrical input power of 3 kW. |
| Cooker hoods | Fans in cooker hoods where the total maximum electrical input power of the fans is less than 280 W. |
| High-speed fans | Fans whose best efficiency point occurs at 8,000 revolutions per minute or higher. |
| Small jet fans | Jet fans with a maximum electrical input power of less than 750 W. |
| ATEX fans | Fans designed and placed on the market exclusively for use in potentially explosive atmospheres. |
| Emergency fire safety fans | Fans designed exclusively for emergency situations and capable of operating for at least one hour at temperatures of 300 °C or higher. |
Additional exemptions apply to specific applications, including certain fans used in nuclear installations, military and civil protection equipment, and the transport of certain gases or materials.
Certain battery-powered and manually operated equipment, as well as air circulation fans, are also excluded from the scope.
Important considerations regarding exemptions
Whether a fan actually qualifies for an exemption depends on its specific design, construction and intended use. The description of an application alone is not always sufficient to establish whether an exemption applies.
For example, ATEX fans must be designed and placed on the market exclusively for use in potentially explosive atmospheres.
For smoke extraction fans, it is important to distinguish between fans designed exclusively for emergency situations and fans used both for normal ventilation and smoke extraction in the event of a fire. The latter are also known as dual-use fans: fans that are used for both normal ventilation and emergency situations. These fans do not automatically qualify for the exemption for emergency fans.
When such fans are also used for normal ventilation, it must be assessed which ErP requirements apply. This is particularly important for smoke and heat exhaust fans that are also used during normal operation.
If in doubt, consult the manufacturer or a specialist to determine which requirements apply to a specific fan type.
5. What changes to the technical requirements?
The new regulation introduces additional requirements for energy efficiency and the information that must be available for a fan. Greater attention is also given to performance at different rotational speeds and opportunities for repair.
5.1 Fan efficiency
The minimum efficiency requirements have been tightened. The required efficiency varies depending on the fan type and is specified in the annexes to the regulation.
When determining efficiency, the performance of the fan configuration is assessed, including the relevant components that must be taken into account under the legislation.
The design of components such as the impeller, motor and housing can influence the final performance. Any frequency inverter used also plays a role.
European legislation distinguishes between different measurement categories (A, B, C and D, and E for jet fans). These determine the conditions under which the fan is measured, for example with a free inlet or with a duct connected.
A distinction is also made between static and total efficiency.
The minimum efficiency is determined based on the fan type, electrical input power, measurement category and the corresponding minimum efficiency grade.
Specific calculation methods or additional correction factors apply to certain fan designs. Cross-flow fans and jet fans, for example, have their own efficiency requirements.
It is therefore important to assess the fan in the configuration for which its performance has been established.
5.2 Performance at different rotational speeds and part-load conditions
An important addition to the new legislation is the focus on performance at different rotational speeds.
In practice, fans do not always operate at their maximum speed. For applications where fan speed is controlled, it is therefore important to know how the fan performs at lower speeds as well.
From 24 July 2027, manufacturers must provide additional information on performance at different rotational speeds for the fans concerned.
For most standard fans, this means that at least three performance curves must be available:
- A performance curve at the fan’s inherent speed.
- A performance curve at a lower speed between 40% and 50% of the inherent speed.
- An additional performance curve at a speed between the other two speeds.
The inherent speed is the speed assigned to the relevant fan according to the definition in the regulation. The amended definition also takes into account fans operated with a frequency inverter.
Different or modified information requirements apply to certain fans, including custom-built fans, jet fans and fans with multi-speed motors.
This additional information enables designers, consultants, installers and users to better assess how a fan performs under different operating conditions and speed control settings.
5.3 Repair and availability of spare parts
The regulation also introduces new requirements relating to resource efficiency and product lifetime.
For fans whose first units are placed on the market from 24 July 2026 onwards, manufacturers, importers or authorised representatives must make certain spare parts available to professional repairers.
These include the following components, where they form part of the relevant fan:
- Electric motors with a rated power of less than 10 kW.
- Impellers.
- Stator components.
- Mechanical drive components.
- Frequency inverters.
- Sensors.
- Fan bearings.
- Motor bearings for certain integrated motor designs.
- Wear parts.
- Required fastening and connecting materials.
Similar obligations apply to safety-critical fans, but access to spare parts and repair information is restricted to professional repairers authorised by the manufacturer.
The required spare parts must become available no later than 24 July 2028 or two years after the first unit of the relevant model is placed on the market, whichever date is later. They must then remain available until at least ten years after the last unit of the model has been placed on the market.
Delivery time requirements also apply. Unless other arrangements have been specified in a contract or product information, spare parts must be delivered within six weeks of receipt of the order at the latest.
In addition, the relevant components must be replaceable without causing permanent damage to the fan.
Where manufacturers provide software and firmware updates, these must remain available free of charge for at least ten years after the last unit of the model has been placed on the market.
Repair information
Manufacturers must provide professional repairers with access to the necessary repair information.
This information includes technical manuals, disassembly instructions, wiring diagrams, component information and diagnostic data, among other things.
Different provisions apply to certain custom-built fans where the availability of spare parts has been contractually agreed.
5.4 More comprehensive product information
Manufacturers must make more information about their fans available.
This includes:
- The fan type and its main technical specifications.
- The fan efficiency and the measurement category used.
- Static or total efficiency.
- The electrical input power at the best efficiency point.
- The airflow volume and pressure difference at the best efficiency point.
- Information about the motor and any speed control.
- Whether the efficiency assessment is based on the use of a frequency inverter and whether this is integrated or must be installed externally.
- The relevant components used to determine performance.
- Performance data and, where applicable, part-load performance curves.
- Information about repair and the availability of spare parts.
- Information about maintenance, disassembly and recycling.
Some of this information must be permanently displayed on or near the fan’s nameplate.
Other information must be included in the technical documentation and product information supplied with the fan or made available through a website.
The required product information must remain available on an accessible website for at least twenty years after the last unit of the relevant model has been placed on the market.
Different information requirements apply to certain custom-built fans. For example, the relevant information must be made available with the commercial offer.
6. Who is responsible for compliance?
The regulation establishes obligations for various parties in the supply chain, including manufacturers, importers and authorised representatives.
Responsibility for the conformity of a fan depends on the role of the party involved and the way in which the product is placed on the market.
Manufacturer
In principle, the manufacturer is responsible for the design and conformity of the fan.
This includes:
Carrying out or commissioning the required measurements and calculations.
Demonstrating that the fan meets the applicable efficiency requirements.
Preparing and retaining the technical documentation.
Providing the required product information.
Drawing up the required declaration of conformity.
Importer
The importer must, among other things, verify that the manufacturer has fulfilled the applicable obligations and that the required documentation is available.
The importer also has its own obligations relating to product information, documentation and cooperation with market surveillance authorities.
Authorised representative
An authorised representative can perform certain tasks on behalf of the manufacturer, within the limits of the mandate granted by the manufacturer.
The manufacturer remains responsible for the conformity of the product.
Distributor and supplier
A distributor or supplier does not automatically have the same obligations as the manufacturer. However, they must handle the products they offer on the European market with due care.
A distributor must, among other things, check that the required product information is available and must not offer products if they know, or should reasonably suspect, that these do not meet the applicable requirements.
When a company places a product on the market under its own name or brand, or modifies a product in such a way that this affects its conformity, additional responsibilities may arise.
Assembling or modifying fans
When combining or modifying components, it is important to check whether the original performance data still applies.
For example, using a different motor, impeller or housing can affect the fan’s performance and established conformity.
If there is any uncertainty about the responsibilities involved in assembling or modifying a fan, it is advisable to contact the original manufacturer or a specialist.
7. What has changed compared with the previous regulation?
The new legislation builds on Regulation (EU) 327/2011 but introduces additional requirements and clarifications. The table below summarises the main changes.
| Subject | Previous regulation (EU) 327/2011 | New regulation (EU) 2024/1834 |
|---|---|---|
| Application date | Applicable until 24 July 2026. | Applicable from 24 July 2026. |
| Energy efficiency | Minimum efficiency requirements for fans. | New efficiency requirements and revised calculation methods. |
| Performance data | Focus on performance at the best efficiency point. | Additional information on performance at different rotational speeds for the fans concerned. |
| Product information | Requirements for technical product information. | More extensive information requirements, including data on fan configuration and performance. |
| Repair and spare parts | Less extensive requirements under this regulation. | Additional requirements for the availability of certain spare parts and repair information. |
| Product lifetime and circularity | Limited attention within the fan regulation. | Greater focus on repair, disassembly and material reuse. |
| Replacement fans | Existing transitional and replacement provisions. | Specific transitional arrangement for certain replacement fans until 24 July 2037. |
The precise requirements and transitional provisions depend on the fan type and its application. The table therefore provides a general comparison and is not a complete overview of all legislative changes.
8. What does this mean in practice?
The new regulation requires manufacturers and suppliers to align their products and documentation with the updated requirements in good time.
Companies purchasing fans, using them in their applications or incorporating them into their own products should also take the legislation into account when selecting a fan.
Here are some practical points to consider:
Check the product specifications
Check whether the fan meets the applicable efficiency requirements and whether the necessary performance data is available.
Coordinate with your supplier
Discuss which requirements apply to the selected fan and request the corresponding technical documentation and conformity information.
Pay attention to the fan configuration
When components are combined or replaced, this can affect the established performance and responsibilities for conformity.
Consider the application
Not every fan is subject to the same requirements. For special applications, such as ATEX and smoke extraction fans, it is important to assess whether the fan falls within the scope of the regulation or qualifies for a specific exemption.
Ask about performance at different rotational speeds
For fans operated with a frequency inverter, it is advisable to consider not only the nominal operating point but also performance at lower rotational speeds.
Consider repair and spare parts
The new legislation introduces additional requirements for the availability of certain spare parts and repair information. This can be important when considering the maintenance and service life of an installation.
Look beyond electrical input power alone
An efficient fan can help reduce energy costs. The actual savings depend on factors such as the operating point, speed control and number of operating hours.

9. Frequently asked questions about the ErP Regulation
When did the new ErP Regulation come into force?
Regulation (EU) 2024/1834 has applied since 24 July 2026. From that date, it replaces the previous Regulation (EU) 327/2011, subject to certain transitional arrangements.
Which fans are covered by the new legislation?
The regulation applies to fans with an electrical input power of 125 W up to and including 500 kW at the best efficiency point (BEP). Various exemptions and specific provisions apply to certain applications.
Does the regulation also apply to fans manufactured outside the EU?
Yes. The legislation applies to fans placed on the European market or put into service. The country in which the fan was manufactured does not matter. Importers have their own obligations under the regulation.
Do existing ventilation systems need to be modified?
The regulation establishes requirements for placing fans on the market or putting them into service. This does not mean that existing installations automatically need to be modified. However, specific requirements and transitional provisions may apply when a fan is replaced or placed on the market again.
Are there exemptions for ATEX fans and smoke extraction fans?
Yes. Certain fans designed and placed on the market exclusively for specific applications are exempt, subject to certain conditions. This includes ATEX fans and certain emergency fire safety fans.
Different requirements may apply to fans that combine multiple functions. Consult the manufacturer when assessing a specific fan type.
Can an older fan still be supplied as a replacement fan?
Transitional provisions apply to certain replacement fans. Subject to specific conditions, these remain applicable until 24 July 2037. This does not automatically apply to every replacement situation. The manufacturer or supplier can confirm whether a particular fan qualifies.
What is the difference between ErP Regulation (EU) 2024/1834 and ESPR Regulation (EU) 2024/1781?
EU 2024/1834 contains specific ecodesign requirements for fans. EU 2024/1781 is the broader Ecodesign for Sustainable Products Regulation (ESPR), which provides a framework for sustainability and product requirements across various product groups.
The two regulations therefore have different scopes and should not be confused.
