Abstract
Thanks to its unique membrane technology, the expanded Fluoro Resin Media (eFRM) HEPA filter medium has been the medium of choice for numerous end users in the life science and microelectronics industries for several years. In addition to the low pressure drop, the focus in these segments is on risk minimization through high mechanical stability and chemical resistance.
Due to the extremely low pressure drop, the eFRM filter medium is predestined for use in high-flow HEPA filters such as those used in ventilation systems for high-purity environments. To investigate this application, a “1000 days” test was conducted under real outdoor air conditions.
The article deals with the short- and long-term behavior of the filters. Furthermore, economic implications resulting from the favorable pressure drop characteristics of eFRM HEPA filters compared to glass fiber-based HEPA filters are of interest. For this purpose, the operating costs as well as the Total Cost of Ownership are discussed, especially against the background of the strongly increasing electricity costs in different countries. The carbon footprint during operation of the different filters will also be discussed.
