Our Filter-Campus offers you pure knowledge about test standards of well known filter classes within the filter industry. Learn more about requirements on air filters in order to choose the right filter type for your application. Our Case Studies analyse the optimal filtration mix for different purposes and present you achievable benefits for your operation. And our short clips give you a quick round trip through the entire filter world of EMW!

Topics:

Case Study : (H)EPA Filter Upgrade for a LM6000 gas turbine

At a project site in South East Asia EMW's (H)EPA-Upgrade of the air intake filters increased the availability and optimized the operation of a LM6000 gas turbine.

ISO 29461 : ISO 29461 - Air intake filter systems of rotary machinery

ISO 29461-1:2021 - A test method to determine the performance of air filters in the service area of rotating machinery such as stationary gas turbines, compressors and other stationary internal combustion engines.

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?

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.

COVID-19 : HEPA H13 and H14 air filters for air purifiers.

HEPA filters for air purifiers to minimise the risk of COVID-19 infections.

Case Study : EMW® (H)EPA air filters ensure compressor efficiency

Avoiding compressor efficiency losses? No problem! Our EMW® (H)EPA filters secure the performance of your machine!

COVID-19 : HEPA filter against viruses | EMW^®

With a HEPA filter, viruses such as the coronavirus can be filtered out of the room air. We offer matching H13 and H14 filters. Learn more now!

Case Study : Static filters vs. pulse filters for gas turbines

Learn more about the comparison of static filters and pulse filters in practical gas turbine operation.

General : PORET® Coalescer Media in comparison to Glass & Synthetic Media

Learn more about the advantages of Poret® Coalescer media in comparison to any synthetic media.

ISO 16890 : ISO 16890 Replaces EN 779

ISO 16890 regulates classification of particulate filters for room air. This new standard, in effect since late 2016, has superseded European standard EN 779 in mid-2018.

Case Study : Capacity Loss in Gas Turbines

Capacity loss due to contamination of the compressor? The upgrade of EMW for improved filter efficiency!

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?

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.

ISO 16890 Video : Filter Test according ISO 16890

This clip shows you on an example of a compact filter, how a filter gets tested according ISO 16890.

ISO 29463 : Clip ISO 29463

There are many standards for HEPA filters. We'll show you how the new ISO 29463 supplies clarity in the jungle of filtration test standards.

Case Study Video : The Impact of (H)EPA filters on the performance of a gas turbine

Andrew Thomson, our presenter at the Combined Cycle Power Plant User Symposium, explains you how significant the impact of (H)EPA filters on the performance of a gas turbine is!

Case Study Video : Case Study: EMW®´s Filter-Upgrade for LM6000 Gas Turbines

ISO 29461 Video : Clip ISO 29461-1:2013

The filter test standard ISO 29461-1:2013 is currently a valid standard for static filter elements in the application of air inlet filters for gas turbines. In this video you will find out more about the test sequence of the filter standard and why you, as the operator of a gas power plant, have probably not come into contact with ISO 29461 yet.

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?
