Abstract

The paper presents the study results of the fiber furnish effect on the efficiency of air purifi-cation by separator papers used in evaporating elements of evaporative coolers. Samples of separator papers were modeled in laboratory conditions from glass fibers of four grades, differing in nominal diameter (0.1; 0.25; 0.4; 0.6 microns). We obtained one-, two-, three- and four-component samples. The fibers in the composition varied between 0 and 100 % in 25 % increments. The efficiency of air purification was evaluated by the method based on sizing of the most penetrating particles of oil aerosol (Most Penetration Particle Size). We achieved the EPA (effective material) and HEPA (highly effective) air purity classes by all studied compositions. The exception was a sample made of 100 % superfine glass fiber with a nominal diameter of 0.6 micron. Additionally, we evaluated the efficiency of air purifica-tion for particles of 0.3 micron in size. The size of the most penetrating particles for most compositions was 0.1...0.15 micron. The lowest efficiency was noted for two-component samples made of fibers with a nominal diameter of 0.4 and 0.6 micron, respectively. This corresponded to theoretical concepts and previously obtained results: the absence of finer fibers in the composition led to the production of coarsely structures with less efficient air purification. The efficiency of air purification for particles with a size of 0.3 micron was higher in comparison with the size of the most penetrating particles. This corresponded to the provisions of the Mechanics of Aerosols by Fuchs. Two-component samples made of fibers with a nominal diameter of 0.4 and 0.6 micron had the lowest efficiency of air purifi-cation, since the absence of thinner fibers in their composition resulted in coarsely struc-tures. Maximum efficiency was achieved for two- and three-component samples in which the total content of fibers with a nominal diameter of 0.4 and 0.6 micron did not exceed 50 %. These samples corresponded to the H13, H14 air purity classes.
