Description

DONALDSON’S USER-FRIENDLY FILTER RATING SYSTEM With Donaldson’s filter rating system, operators of gas turbine systems have a simpler, more effective way of selecting the optimal filtration solution for their facility. This straightforward approach is based on decades of experience serving gas turbine customers in all climates and conditions, and listening to their needs. Operators identify three main criteria they consider when evaluating a filtration solution: filter efficiency, watertightness, and pulse recovery rate. In response, Donaldson developed a 0-5 point rating scale for each attribute, and rates each of its filters on all three scales. This rating system is designed to help equipment operators optimize productivity and minimize operating costs, for their operating environment. DEFINITION: The most widely recognized performance metric for efficiency is the proportion of inlet air particulates captured by the filter. Because higher-efficiency filters have associated costs, operators need to determine an efficiency rating that maximizes return on investment for their facility. EXPLANATION: By using established standard test methodology, such as ASHRAE52.2, EN779, EN1822 and ISO 16890, Donaldson has worked to simplify how customers classify their filtration application. In this case, an Er5 rating is (H)EPA level filtration and Er0 represents coarse pre-filtration. DEFINITION: In humid or ocean-front locations, resistance to moisture becomes a high priority. Salts and other dissolved solids carried by water can be highly corrosive and often more detrimental than airborne contaminants.
