The European Union is implementing a more tightening regulation for industrial fans under ErP 2026, which will impact a wide range of industries, including agriculture ventilation, HVAC equipment, heat pump, data center cooling, cleanrooms, and industrial ventilation.
Commission Regulation (EU) 2024/1834 will replace the previous Commission Regulation (EU) No. 327/2011, establishing higher minimum energy efficiency requirements and expanded product information obligations. The new rules introduce higher efficiency threshold for manufacturers, OEMs and importers supplying the EU market.
For HVAC manufacturers, equipment integrators, distributors, and procurement teams, understanding these changes is essential to maintaining market access. As a leading manufacturer of EC fans and motor solutions, LONGWELL helps customers navigate the transition with technically compliant products, making ErP 2026 requirements easier to understand and implement with confidence.
What is ErP 2026 ((EU) 2024/1834)?
ErP (Energy-related Products) legislation establishes minimum environmental performance requirements for products sold in the European market.
ErP 2026 or EU 2024/1834 focuses on fan as a complete system rather than just individual components. The legislation evaluates fan driven by motor with an electric input power between 125 W and 500 kW. The conformity are linked to the performance of the entire fan assembly, including motor, impeller, electronics, inlet cone and housing. It applies whether the fan is sold independently or integrated into another product such as AHUs, rooftop units, precision air conditioners, data center cooling systems, or industrial ventilation equipment.
In addition to Fan Efficiency Grade (EFG), the regulation focuses more on realistic operating performance like partial-load performance, real operating conditions, broader efficiency range, and overall system losses.
Under ErP 2026, aerodynamically optimized impellers, low-loss motor technologies, and precise electronic control are becoming more and more important.
What ErP 2026 Requires?
To help HVAC manufacturers, OEMs, and procurement teams better understand the new regulation, LONGWELL has summarized the significant changes of Commission Regulation (EU) 2024/1834.
Higher Minimum Fan Efficiency
ErP 2026 raises the minimum energy efficiency requirements for in-scope fans. The regulation applies not only to standalone fan manufacturers but also to those companies that produce incomplete fans, integrate fans into equipment, or sell fan products on the EU market under their own brand name. Manufacturers must ensure that the complete fan assembly, including the impeller, motor, and aerodynamic components, achieves the required efficiency levels based on the updated assessment. The regulation encourages the wider adoption of advanced fan technologies, particularly EC fan solutions.
Expanded Product Information
From 4 July, 2026, manufacturers are required to provide more comprehensive product or technical information, including:
- Model identification and manufacturer details
- Energy efficiency values (at full and partial load)
- Operating characteristics
- Instructions for repair, disassembly, and recycling at end of life
- Other information for specification, installation, and verification
Mandatory Spare Parts Availability
Manufacturers must guarantee the availability of critical spare parts including motors, bearing, belts, and propellers for defined periods and provide the information necessary for maintenance and repair to help extend product service life and reduce waste.
Long-term Online Technical Information
The documentation of fan products should remain accessible online for an extended period after the product is placed on the EU market. This can improve transparency and allows buyers, service providers, and market surveillance throughout the product’s lifecycle.
Key Dates of ErP 2026
While the regulation entered into force in 2024, most technical requirements become mandatory from 24 July 2026. Here are the key dates of ErP 2026:
| Date | Milestone | What It Means |
| July 2024 | 2024/1834 enters into force | 2024/1834 enters into forceThe new ecodesign regulation is officially adopted, beginning a two-year transition period for manufacturers to prepare. |
| 24 July 2026 | ErP 2026 becomes applicable | All standalone fans placed on the EU market within the scope of the regulation must comply with the new minimum efficiency, product information, and documentation requirements. |
| 24 July 2027 | Transition ends for fans integrated into other products | Fans integrated into equipment such as air handling units, heat pumps, chillers, and other HVAC products must comply with the new requirements. |
| 23 July 2037 | End of spare-part fan exemption | Non-compliant spare-part fans used to replace fans in existing installations can no longer be placed on the EU market. |
Who is Affected?
ErP 2026 impacts far more than fan manufacturers. It has a new regulation for companies that design, assemble, import, or HVAC equipment for the European Union market.
The regulation affects:
- Air Handling Unit (AHU) Manufacturers
- HVAC OEMs
- Heat Pump Manufacturers
- System Integrators
- Refrigeration Equipment Manufacturers
- Equipment assemblers and system builders
- Importers
- Distributors placing products on the EU market
With ErP 2026, fan selection is no longer solely an engineering decision—it is also a compliance decision in EU market. Choosing a fan based only on airflow and pressure performance is no longer sufficient; manufacturers must also consider energy efficiency, technical documentation, product information, and long-term regulatory compliance.
Strong Partner for ErP 2026 Fan Compliance
For EU HVAC buyers, ErP-related purchasing is less about one label and more about evidence. Fan ecodesign in the EU is set by Regulation (EU) 327/2011 (the fan “Lot 11” ecodesign measure) and its ongoing revision under the Ecodesign Working Plan, so “2026” is best read as the direction of travel toward tighter system-efficiency expectations rather than a single switch-over date. A good fan supplier should provide the curve package, the applicable compliance files and the installation data needed by the AHU, heat-pump or refrigeration OEM.
EC fans are easier to defend in energy-driven projects because part-load control is built into the fan system. The buyer can compare expected annual power rather than relying on fixed-speed assumptions.
As ErP 2026 raises the bar for energy efficiency and product transparency, selecting an experienced fan manufacturer becomes increasingly important. LONGWELL LWBE3G and LWAE3G are relevant where the project needs an EC alternative to premium European brands with faster sampling, configurable controls and application-specific mechanical options.
FAQs
What is the safest ErP purchasing approach?
Request fan curves, operating-point power, compliance files and control documentation before supplier approval.
Does a motor efficiency claim prove fan compliance?
No. Fan selection should evaluate the complete fan assembly and the operating point.
Why use an EC platform?
EC fans simplify part-load control and make annual energy calculations more transparent.
Which fan types are covered?
The regulation generally applies to axial fans, centrifugal fans, mixed-flow fans, plug fans, and other in-scope fan assemblies with an electric input power between 125 W and 500 kW, whether sold as standalone products or integrated into equipment.
Why are EC fans becoming the preferred choice?
EC fan technology typically delivers higher system efficiency, superior part-load performance, integrated speed control, and lower operating costs, making it easier for many applications to achieve compliance.
