Abstract
A filter system comprises a pressure vessel housing with internal components designed to remove solid particles, semi-solid particles, and liquid droplets from a gas phase media. The filter housing utilizes multiple replaceable filter cartridges. The system includes a keyed filter coalescer cartridge designed to flow from the inside open area of the cartridge to the outside annular area of the housing prior to leaving the system through an outlet nozzle. The key is designed to locate a baffle of the filter cartridge inlet side end cap in a certain orientation as to provide enhanced liquid removal performance for the system. The baffle may also serve as a handle.
