Lab-scale design of two layers wood cellulose filter media to maximize life span for intake air filtration

Abstract The requirement of continuous and stringent growth on filtration performance, including longer life span, higher overall efficiency, lower initial pressure drop and more cost effective, has still drove filter media manufactures to research and develop. One of the possible way to achieve the...
