GE Frame 7FA Parts — MS7001FA Platform
Complete hot gas path, combustion, and turbine components for the 171 MW class GE Frame 7FA heavy-duty gas turbine. ISO 9001 & AS9120 certified.
171 MW Class Heavy-Duty Gas Turbine
The GE Frame 7FA (MS7001FA) is a 171 MW, 60 Hz heavy-duty gas turbine widely deployed in simple cycle, combined cycle, and cogeneration plants across North America, the Middle East, and Asia-Pacific. With an 18-stage compressor and 3-stage turbine, the 7FA platform delivers a heat rate of approximately 9,600 Btu/kWh (LHV) and supports DLN 2.6+ combustion for ultra-low NOx emissions. We stock the frame 7FA 1st, 2nd, and 3rd stage buckets and nozzles, 7FA transition pieces, 7FA combustion liners, and DLN 2.6 fuel nozzles you would order for a complete hot gas path overhaul.
Common build levels include 7FA.e, 7FA.05, 7FA.04, and 7FA.03. Whether you are planning a 7FA hot gas path kit for an inspection window or sourcing 7FA.03 combustion parts for an emergency repair, our inventory covers all major variants with OEM-licensed and aftermarket-certified components backed by full traceability.
