ISO 29461 Video : Clip ISO 29461-1:2021

As already announced: ISO 29461 has finally received the update! Now you, as an operator of a rotary machinery such as a stationary gas turbine or a compressor, have your own filter test standard including a classification with the filter classes ISO T1 up to ISO T13. Watch our latest video to learn more about the test procedure and the new filter classes of this filter test standard.

COVID-19 General Video : Clip aerosols vs. particles

Unfortunately, the term 'aerosol' is often wrongly defined and mistakenly interpreted as a particle mixture. But how is an aerosol correctly defined? What is the difference to a particle? And what do we mean by talking about aerosol filters and aerosol filtration?
