Abstract
A turbomachine includes a compressor portion having an intake and a filtration system having an interior and an exterior. The filtration system is arranged upstream of the intake and includes a drain capable of fluid communication with the exterior of the filtration system. The drain includes a one-way valve that allows liquid separated from air flowing through the interior of the filtration system to pass through the drain to the exterior of the filtration system in a first direction, and substantially limits a flow of unfiltered air from entering the intake from the exterior in a second direction.
