The present study has been undertaken to analyze the filtration performance of two different nonwoven polypropylene filter media, viz. needle felt and spun-bonded sandwiched with granular activated carbon of varying concentration under different face velocities. The materials are studied on a laboratory based cabin air filter test rig. Spun bonded material reveals relatively lower emission and pressure drop. Interestingly, lower face velocity reveals relatively improved filter behavior in case of both the filter materials. Further, a reduction in downstream emission in terms of PM2.5 & PM10, number concentration and peal pressure drop is observed at higher concentration of activated carbon.

Abstract


The present study has been undertaken to analyze the filtration performance of two different nonwoven polypropylene filter media, viz. needle felt and spun-bonded sandwiched with granular activated carbon of varying concentration under different face velocities. The materials are studied on a laboratory based cabin air filter test rig. Spun bonded material reveals relatively lower emission and pressure drop. Interestingly, lower face velocity reveals relatively improved filter behavior in case of both the filter materials. Further, a reduction in downstream emission in terms of PM2.5 & PM10, number concentration and peal pressure drop is observed at higher concentration of activated carbon.
