MULTI-LAYER FILTER, GAS TURBINE INCLUDING A MULTI-LAYER FILTER, AND PROCESS OF FILTERING

摘要

A multi-layer filter, a gas turbine including a multi-layer filter, and a process of filtering are disclosed. The multi-layer filter includes a nano-fiber layer positioned to receive an airflow, a coalescing base medium layer, and a membrane layer. The coalescing base medium and the membrane layer are positioned for the airflow to travel through the nano-fiber layer and the coalescing base medium layer, then through the membrane layer. The gas turbine includes an inlet and the multi-layer filter in a filter portion. The process includes positioning the multi-layer filter and directing an airflow through the multi-layer filter
