conference contribution

critical role of air filters performance. Accurate filter performance prediction is important to estimate
filter lifetime and reduce energy and maintenance operating costs. To ensure appropriate filter
selection for a specific application, the effect of pleat count and surface area on filter design and
performance has been investigated. This paper examines the effects of air velocity on permeability
during operation of HEPA pleated V-shaped filters, and the effect of pleat count on the initial pressure
drop and fractional efficiency using DEHS testing according to DIN 1822. An empirical equation for
predicting the efficiency of the filter is suggested.
