ABSTRACT:
Methods for cleaning air intake for a gas turbine system include utilizing filter arrangements that include a barrier media, usually pleated, treated with a deposit of fine fibers. The media is particularly advantageous in high operating temperature (140 to 350° F.) and/or high humidity (greater than 50 to 90% RH) environments.
