Abstract
The ASME AG-1 Code specifies minimum rated airflow based on standard cubic feet per minute (SCFM) for axial high efficiency particulate air (HEPA) filters and actual cubic feet per minute (ACFM) for radial HEPA filters. This study illustrates the variation in filter efficiency of axial HEPA filters subjected to ACFM and SCFM flow conditions. The filter test matrix consists of axial HEPA filters rated at 1,000 and 1,500 CFM with varying filter pack types. Each filter is subjected to pressures from 14.70 psi to 11.25 psi, temperatures of 70°F to 170°F, and relative humidities of 50% to 90%. Evaluation of the effects of designating ACFM or SCFM are based upon the filter efficiencies of generated Dioctyl Phthalate (DOP) particles at a diameter of 0.3 micrometers. A correlation model is developed to convert filter efficiency and pressure drop at elevated conditions to those of standard pressure, relative humidity, and temperature.
