Abstract

Abstract

In the air and helium gas,based on MPPS and Sodium flame methods,this paper calculates the filtration efficiency and resistance of three levels of HEPA filter media.The results show that comparing with the air,in helium gas,filter media have lower resistance and higher efficiency,and secondly,at the same filtration rate and particle diameter,with the rise of environment temperature,the filter media have higher resistance and efficiency.
