First Study Of Hepa Filter Prototype Performance To Control The Airborne Pollunon

ABSTRACT:

This Paper will report the efficiency test result of the filtration tool prototype of High Efficiency Particulate Air (HEPA filter) for low temperature, to control the airborne pollution of aerosol particle of solid and liquid.

The prototype design of HEPA filter was based on the characteristic data of filter material (fibrous diameter{density, filter thickness), flow rate of air and first pressure drop. From the result of laboratory scale test, using DOP I PSL aerosol with 0.3 ~ diameter and the flow rate of 3.78 m3 I min, was obtained filtration efficiency revolve between 89.90 and 99.94 % for the filter prototype of A, B, C and D. The efficiency estimation of theory with filtration progralrune and the experiment was different amount I %. The value of the prototype efficiency of D filter was not far different with AAF-USA filter and its price is cheaper 30 % than the price of AAF-USA filter.
