Performance Criteria HealthWay DFS FILTRATION SYSTEM HEPA FILTRATION SYSTEM Filtration Efficiency Enable 99.999999 % system filtration efficiency down to 0.007 micron – at lower pressure drop of HEPA see table 1 The technology addresses the viral size ultrafine particles arrest efficiently System filtration efficiency - double HEPA filtration possible due to the lower pressure drop of the primary DFS filters. This eliminates the need for ULPA or better filters. 99.97% @ 0.3 micron doesn't address viral size ultrafine particles efficiently Efficiency increases up to 99.97% but with pressure drop penalty Microbial inhibition & Bioburden DFS filters are highly energy efficient and result in extremely low bio burden in cleanrooms They create high energy field that leads to deactivating viable microbes such as bacteria, fungus and viruses Lower Bioburden of bacteria, viruses and fungus NA Terminal cleanroom filters Protect terminal cleanroom filters This is essential since HVAC systems can introduce contamination, which can clog or damage terminal filters. With DFS in Duct Filters, terminal filters should never require replacement or maintenance. Only the In Duct DFS filter needs replacement - cleanroom not contaminated during filter change. Typical designs requires terminal HEPA Maintenance Costs Lower Maintenance Costs Can last up to three times longer life than conventional HEPA's due to lower pressure drop and pleats per inch characteristics. Higher maintenance cost due to life cycle and loading density Energy Consumption Ultra Low Energy Consumption due to low pressure drop (see graph1) Unlike FFUs, they enable Flow-rate/Ceiling Coverage independence - Higher performance at lower airflow rates. Higher energy Consumption due to higher density and pressure drop over time Achieving ISO classes The HealthWay DFS filters provide the necessary filtration for such applications. Only blank ceiling Multiple HEPA ULPA system required to achieve ISO classes
