Abstract
A filter cartridge assembly includes a first filter including a first cavity defined therein and a second filter coupled to the first filter. The second filter includes a second cavity defined therein in flow communication with first cavity. The filter cartridge assembly also includes at least one pre-filter extending about the first filter and the second filter such that a third cavity is defined between the at least one pre-filter and at least one of the first filter and the second filter.
Claims15
A filter cartridge assembly comprising:
- a first filter including a first cavity defined therein;
- a second filter coupled to said first filter, said second filter including a second cavity defined therein in flow communication with said first cavity;
- at least one pre-filter extending about said first filter and said second filter such that a third cavity is defined between said at least one pre-filter and at least one of said first filter and said second filter, wherein air flow from the third cavity to the second cavity passes through at least one of said first filter and said second filter, wherein the pre-filter is a water coalescing filter configured to channel water away from the first filter and the second filter;
- at least one spacer extending between said at least one pre-filter and at least one of said first filter and said second filter such that said third cavity is at least partially defined by said at least one spacer, said at least one pre-filter, and said at least one of said first and said second filter, wherein said at least one spacer is at the same axial location along a centerline of the filter cartridge assembly as a junction of said first filter and said second filter.

A turbine engine system comprising:
- a turbine;
- a compressor coupled upstream from said turbine;
- and
- an inlet filter house coupled upstream from said compressor and comprising at least one filter cartridge assembly configured to at least partially remove particulates and moisture from an inlet airflow channeled to said compressor, said at least one filter cartridge assembly comprising:
- a first filter including a first cavity defined therein;
- a second filter coupled to said first filter, said second filter including a second cavity defined therein in flow communication with said first cavity;
- at least one pre-filter extending about said first filter and said second filter such that a third cavity is defined between said at least one pre-filter and at least one of said first filter and said second filter, wherein air flow from the third cavity to the second cavity passes through at least one of said first filter and said second filter, wherein the pre-filter is a water coalescing filter configured to channel water away from the first filter and the second filter;
- at least one spacer extending between said at least one pre-filter and at least one of said first filter and said second filter such that said third cavity is at least partially defined by said at least one spacer, said at least one pre-filter, and said at least one of said first and said second filter, wherein said at least one spacer is at the same axial location along a centerline of the filter cartridge assembly as a junction of said first filter and said second filter.
