A unique high-efficiency particulate air (HEPA) filter medium has been developed for applications in high temperature and high pressure environments. This filter medium is a composite made from quartz and stainless-steel fibers that have been sintered together. The composite medium has the same efficiency and pressure drop as standard HEPA glass media, but has four times the tensile strength and can operate continuously at temperatures up to 500°C. In a conventional HEPA, the binder burns out above 250°C and the medium loses its strength; our composite filter medium has no comparable loss of strength even at 500°C. 8 refs., 8 figs., 1 tab.

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.

(Contract DA 44-177-tc-495, Proj. 9R38-01-01745) (TREC TR 61-57)Unclassified report DESCRIPTORS: *A IR INTAKE FILTERS, Design, Tests, 8helicopters, Liaison planes, Military aircraft, *Airplane engines, manufacturing methods, Carburetors, Cooling. Open-ended Terms: H-23. The design and prototype field evaluation of a new high capacity, high efficiency air filtration system for use on ligh fixed and rotary wing aircraft is described. This work was the outgrowth of the original development of an optimum filter medium to protect the air induction s stem of aircraft from the ingestion of large amounts of dust and other air-borne contaminants. Preliminary laboratory testing and a field t t of the new engine air filtration system were carried out using an A R Y -23 helicopter as a test ve icl T HE FIELD TEST PROGRAM CULMINATED WITH THE CERTIFICATION F THE AIR FILTER UNIT BY THE Federal Aviation Agency. Results of both laboratory and field testing are reported in detail. (Author).
