Technical Reference
Filter Media Design and Development Filter Media Media is a term used to describe any material used to filter particles out of a fluid flow stream. From traditional cellulose to synthetic, the development of proprietary filtration substrates is at the heart of every Donaldson filtration system. If our existing media formulation doesn’t meet our customer’s specifications, our scientists use our in-house media development laboratory to design new formulations to meet those needs.
Media Development From traditional cellulose to nanofiber – the development of proprietary filtration substrates is at the heart of every Donaldson filtration system. If one of our existing media formulations does not meet our customer’s specifications, our scientists use our in-house media development laboratory to develop new formulations that meet or exceed your requirements.
Media Characterization Testing • Proprietary formulations • Permeability • Tensile strength
• Mullen burst • Basis weight • Pore size • Thickness • Gurley stiffness • LEFS bench • 3-Point bend
In-House Media Mill • For application development • Trial media production runs • Development of proprietary formulations
Donaldson has many internally developed proprietary computer models which enable us to predict media performance for a given fiber mixture, initial pressure loss for filter elements of various configurations, and filter loading with many different contaminants.This enables us to quickly work through many design concepts to optimize the filtration system for a unique application. Synthetic media captures more and smaller contaminants than cellulose media. When an application requires higher efficiency filtration than cellulose filter media can deliver, Donaldson uses synthetic media technology. Look for more information on filtration media available within the fuel, lube and coolant filtration sections.
