iecex vs atex

General : iecex vs atex

For use in potentially explosive atmospheres, air filters must meet special requirements. Until recently, these requirements were laid down in the ATEX Directive. However, this directive no longer applies to air filters! In order not only to continue to provide safety in potentially explosive atmospheres, but also to be able to prove it, the former ATEX filters are now certified to IECEx. The difference between ATEX and IECEx is explained below.

What is an aerosol?

COVID-19 General : What is an aerosol?

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

Clean Air Delivery Rate

COVID-19 General : Clean Air Delivery Rate

The Clean Air Delivery Rate is considered the evaluation standard for air purification devices. How does the determined value help us to evaluate the filter efficiency? And is an evaluation based on the Clean Air Delivery Rate sufficient for choosing the right air purifier? Learn more about the definition of the Clean Air Delivery Rate, how it is calculated and what you need to consider when evaluating the CADR value.

Effective Filter Media Area

General : Effective Filter Media Area

Effective filter media area is an important characteristic of an air filter. How is effective filter area determined and calculated? And does higher effective area really increase a filter’s separation efficiency?

Dust Holding Capacity

General : Dust Holding Capacity

We will take a closer look at dust holding capacity, its meaning, the test procedures used to determine it and its relevance to practice.

Clip aerosols vs. particles

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?
