Fans according to EN 12101-3: everything about smoke and heat extraction
Fans used for smoke and heat extraction during a fire must meet strict requirements. The European standard EN 12101-3 specifies the classification, requirements, and testing methods for fans that need to perform reliably in these situations. This article explains what the standard entails, what to consider when selecting an fan, and which temperature classes exist.
What is EN 12101-3?
EN 12101-3:2015 is the current European standard for mechanical smoke and heat extraction fans. These fans remove smoke and heat during a fire from buildings such as parking garages, industrial halls, tunnels, or stairwells. This improves visibility for evacuation and emergency services and limits fire damage.
To comply with the standard, a fan must:
Be specially tested for smoke and heat extraction at extreme temperatures;
Be correctly marked with the appropriate temperature class (e.g., F200, F300, F400, or F600);
Include corresponding test reports and CE marking.
The standard is part of the broader European fire safety framework for buildings (EN 12101 series).
Temperature classes according to EN 12101-3
The main classification in EN 12101-3 is the temperature class. This indicates up to which temperature the fan can withstand and how long it can operate under those conditions:
Class Temperature Operating Time
F200 200°C 120 minutes
F300 300°C 60 minutes
F400 400°C 120 minutes
F600 600°C 90 minutes
Note: The entire fan (including motor, impeller, casing, and bearings) must be tested under these conditions. Only then can the product be delivered as certified according to EN 12101-3.
Frequently asked questions about EN 12101-3
What does F300 mean for fans?
It means the fan is certified for use at 300°C for 60 minutes. This is a common class for smoke and heat extraction applications in parking garages and buildings.
Is EN 12101-3 mandatory?
In many countries (including the Netherlands), compliance with this standard is mandatory when fans are part of a building’s fire safety concept.
What is the difference between F400 and F600 fans?
F600 fans are designed for more severe conditions (600°C, 90 min.) and are used in tunnels or industrial situations with increased fire risk.
