Systemair is a Swedish-headquartered manufacturer of smoke-extract fans, founded at Skinnskatteberg in 1974 and still headquartered there with several hundred Swedish employees — Sweden is its home country, which is why it is listed here rather than treated as a pan-European group. Its centrifugal smoke-extract fans are stated on its own Swedish product pages to be tested to EN 12101-3 and CE-certified to that standard by TÜV SÜD, certified F400 for a hundred and twenty minutes; its roof fans are tested to EN 12101-3 at the LGAI laboratory in Barcelona and CE-certified by BSI. Classes published across the range run F200, F300 and F400, and the jet fan ranges are declared certified to EN 12101-3 in class F300 and F400 for car parks and tunnels. Notified bodies are named rather than numbered, and no certificate number appears on the Swedish site.
