How to Choose the Right Smoke Extract Fan?
Smoke extract fan must be tested and CE marked by international accredited organizations in accordance with EN 12101-3 standard within the scope of System-1 according to Construction Materials Regulation. According to the EN 12101-3 standard, products in the temperature class suitable for the project and local authority should be selected and used from strength classes such as F200 (200 ºC/2h), F300 (300 ºC/1h/2h), F400 (400 ºC/2h).
How to Use a Smoke Extraction Fan?
Smoke extract fan must work correctly and together with other systems. Positive pressurization systems should be used in conjunction with fans to limit smoke entry and spread in escape stairs, elevators and indoor areas and to keep the air clean. At this point, control systems should be used for the integrated and correct operation of smoke evacuation fans and other systems, and building automation should be integrated with fire systems.
