AHU Filter Testing 

In 2013 AAF Flanders, in collaboration with Daikin Industries, developed eFRM, the first membrane media to be compatible with oil-based test aerosols, such as PAO. Since then, tens of thousands of HEPA filters with eFRM media have been installed in hundreds of applications, with a failure rate of less than 1%.

Advantages of eFRM

Compared to other HEPA media options for Life Science industries, eFRM offers:

Advantages of eFRM media

Superior Strength

Traditional glass HEPA filters frequently suffer damage when:

  • Handled
  • Shipped
  • Stored
  • Installed
  • Tested

By comparison, eFRM media is practically indestructible. Therefore, operators of Life Science applications have found that they can abandon the practice of purchasing and storing extra quantities of HEPA filters well above the number that their facilities actually require.

Enhanced Efficiency

The benefits of membrane media do not end at its robust strength. As is true with PTFE/ePTFE media, eFRM media boasts a pressure drop that is roughly half that of glass media. This decreased airflow resistance equates to significantly lower energy usage and reduced strain on HVAC equipment.
