Absolute and Nominal Rated Filter Elements
Dependent on the nature of the application and process to be filtered, the choice of filter media and method of operation can differ.
The performance of Nominal rated filter elements varies as the element becomes loaded with solids and differential pressure builds up. As a result, they tend to be utilised as an economically sound choice to remove bulk solids and to greatly extend the life of downstream finer filters in a multi stage filter system.
Absolute rated filter elements offer consistent performance throughout their operational life and are used in semi-critical and critical points in the filtration system.
