3M™ High Flow Cartridges Dirt Loading & Filter System Sizing

The dirt holding capacity of particle removal filters is dependent on the rate of fluid flow through the filter. This dirt-holding-to-flowrate response in non-linear and is a critical consideration when sizing a filter system for industrial filtration applications. Understanding how a filter’s dirt holding capacity is impacted as flow increases or decreases will help to project individual filter service life, and also determine how many filters are needed to meet filter change-out targets (as in number of days).

This technical application brief will show how to calculate the dirt load — or dirt removal work that a filter or set of filters will be required to do — as well as how to use the dirt loading information to size a filter system, depending on customer requirements, such as capital costs, system footprint, filter life, etc.
