Smoke extract fans Completely under control – certified safety F400 smoke extract fan with frequency converter

Success! – Testing a smoke extract fan with frequency converter For many years, EN 12101-3:2015 (Smoke and heat control systems – Part 3: Specification for powered smoke and heat exhaust ventilators) was a guarantee for the safety of smoke extraction applications. The standard was revised in 2015, clarifying the defi nition of controllability for powered smoke extraction systems. Previously, if daily ventilation could be controlled via a frequency converter, in the case of a fi re the frequency converter had to be circumvented with a bypass switch. Now a smoke extraction fan can be tested in...

• No need for tricky and expensive installation of a bypass switch • Energy-saving operation via frequency converter possible at all times • Safety systems within the smoke extraction system can be coordinated with each other • Parameterisation of the frequency converter for up to 32 fixed speeds • In case of fire the speed can be regulated via a 4-20 mA signal (e.g. differential pressure control) Most manufacturers switch off the fan shortly after reaching the minimum time for a classification. But what happens if the fire scenarios demand an adapted application of smoke extraction? To find...

We did it! After reaching the classification time, the fan was subsequently operated between partial and full load. By using specified suppliers and frequency converters with a "fire mode" (safety-related emergency operation function), it was possible to repeatedly simulate control in the case of a fire. The system was switched off after a total loading period of almost 200 minutes. After this period, the mechanical and electrical fan components showed no signs of fatigue. Use it! Systemair has the right smoke extraction fan for every application with certified combined safety. This means our...

Systemair now has F400 smoke extract fans ready for you, with frequency converter and highly-efficient IE3 motor. These fans are not just suitable for significantly more efficient requirements, but can also be used for dualpurpose operation (providing extremely efficient everyday ventilation as well as smoke extraction in case of fire). In the case of a fire, the fan can be controlled without a bypass by using the frequency converter. F400 smoke extract fans are available in the sizes 315 to 1600.
