A filter element includes a construction of pleated filter media defining an interior volume. First and second opposite end caps are secured to opposite ends of the filter media. A support structure supports the filter media and is operably oriented in the interior volume. The support structure extends from the first opposing interior face to the second opposing interior face. The support structure is provided to extend less than a full extension between the first end cap and second end cap.

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.

A droplet coalescing filter cartridge is provided. The filter cartridge includes an outer filter tube and an inner filter tube disposed within the outer filter tube, and is configured to provide parallel filtration of a fluid flow. The filter includes a depth media configured to coalesce fine droplets or aerosols from an air flow. The filter cartridge is suitable for use in a coalescing filter assembly including the filter cartridge and a secondary filter element.

A filter is provided for removing contaminants from a gas flow (e.g., an air flow). Multiple panel filters are arranged in a filter housing. The panel filters are arranged parallel or near-parallel to a main gas flow direction and spaced apart to define elongated gas flow channels between adjacent panel filters, each elongated gas flow channel extending generally in the gas flow direction. The elongated gas flow channels include inlet channel(s) and outlet channel(a) arranged in an alternating manner, the inlet channel(s) configured receiving the gas flow at the inlet end and the outlet channel(s) outputting a filtered gas flow from the outlet end. Gas flow redirecting structures are arranged to redirect the gas flow in each inlet channel through adjacent panel filter(s) and into adjacent outlet channel(s). The filter may provide a pressure drop of less than 3 iwg, less than 1 iwg, or less than 0.3 iwg.

The invention is a filter group (1) comprising a filtration region (R) extending between an inlet area (IN) through which fluid to be filtered flows, and an outlet area (OUT) through which filtered fluid flows. The filter group (1) extends along a longitudinal axis (X-X), along a transverse axis (Y-Y) and, in height, along a vertical axis (V-V). Furthermore, the filter group (1) comprises: a filtering panel (3) extending with respect to an imaginary plane (F) and which may be crossed by the filtration fluid in a direction substantially orthogonal to the imaginary plane (F); a baffle panel (4) impermeable to fluid; an inlet chamber (5) defined between the filtering panel (3) and the baffle panel (4), wherein the inlet chamber (5) is open in a proximal region to the inlet area (IN) and is closed in a region which is proximal to the outlet area (OUT).
