Published 27 October 2026
Key points
- EN 12101-3 sets the requirements for powered smoke and heat exhaust ventilators and classifies them by temperature and duration.
- F300 = 300 °C for 60 minutes. F400 = 400 °C for 120 minutes.
- The required class is set by the consultant and the applicable code, not by the supplier.

Reading the certificate
Certified smoke fans carry a certificate number from a notified body. NOVOVENT fans are certified by notified body 0370, e.g. 0370-CPR-1552 (F300, inside the risk area) and 0370-CPR-1553 (F400, inside the risk area — AXITUB PIROS, PIROS BOX, JET PIROS). Always match the certificate number to the model on the datasheet.
