Filtration characteristics of glass fiber filter media at elevated temperatures. Final report, Jul 1974--Jul 1975
Particle collection characteristics of a newly developed, high-purity 'Micro-quartz' fiber filter media and a Gelman Type A glass fiber filter media were evaluated over a range of temperatures (20C to 540C), particle sizes (0.05 micrometer to 26 micrometers), gas velocities (0.5 cm/sec to 51 cm/sec), and particle volatilities. Both types of high efficiency filters proved adequate (>99.9% efficiency) for sampling nonvolatile particles over the above variable ranges. Nonvolatile particle penetration decreased with increasing temperature and increasing filter loading. The effect elevated temperature had on particle collection characteristics was not a determining factor in the application of high efficiency filters. The main problems encountered in the high temperature environment were filter holder leakage and volatilization of gas-borne particles that passed through the filter media.
