Air purification technology in times of the corona virus: Are general ventilation systems still applicable?

Does the corona virus have an effect on air purification technology? This is a question safety officers are currently asking themselves: Does a general ventilation system in metal processing companies lead to viruses being able to spread even further in production? High filter efficiencies and the quality of the integrated filters indicate otherwise.

W3: That is why the IFA certificate is more a seal of quality than a pure test seal

A W3 certificate: This is what most manufacturers of welding fume extraction units want. Because behind this is a test mark that is only awarded to units that meet the highest requirements. In Germany, it is mandatory for some welding work. Internationally, it is now considered an important mark of quality. About the history and significance of one of the most important test marks for welders.
