From the author: Fundamental fluid dynamics equations and empirical data were used to develop a model capable of estimating pressure drop for flow through a pleated filter. The model was developed through the systematic assessment of 20 different custom-manufactured filters utilizing various configurations of the following design parameters: pleat height, pleat count, media thickness, permeability, and filter housing. A one-to-one correspondence was observed between the model's predictions and 600 pressure drop versus face velocity measurements. The model can be used as a design tool to predict minimum initial pressure drop; maximum filtration area; and preferred media properties with respect to permeability versus thickness, thus allowing the filter's useful life and operational energy cost to be improved. The article serves as the ground work for a larger research effort to model pleated filters and banks of pleated filters as platforms for high-resistance materials such as adsorbent-entrapped media.
