GE 7FA.03 7FA.04 Unit FAQs
A new 7FA gas turbine rotor eliminates hidden fatigue and gives you a fresh 144,000 FFH / 5,000 FFS life clock, reducing forced-outage risk and lowering long-term maintenance spend
Yes - after an EthosEnergy engineering review, the compressor rotor swaps into any flared 7FA.03/.04 casing, and the turbine rotor aligns with Gen 4 enhanced-cooling-slot hardware.
Absolutely. We can install EthosEnergy or customer-provided buckets before shipment, or ship the rotor bucket-ready for installation on site.
The rotor meets or exceeds all pertinent TILs, including safety-critical TIL-1576, and is certified for the full OEM life of 144,000 FFH and 5,000 FFS.
With proper outage planning, most plants complete the rotor exchange during a standard major outage window—typically 7–10 days.
Reach our 7FA gas turbine specialists at enquiries@ethosenergygroup.com or via the contact form below for a customized quotation and current delivery timeline.
Yes, we offer a fleet-wide exchange program that lets you cycle rotors through planned outages, minimizing downtime and aligning capital outlay with your maintenance schedule.
The rotor ships on a dedicated skid measuring 28′ 0″ × 7′ 6″ and weighs roughly 96,000 lb (plus a 10,000 lb skid), fitting within standard heavy-haul permit limits.
EthosEnergy offers a comprehensive warranty covering workmanship and materials for the certified service interval; extended coverage and long-term service agreements are available.
We machine wheels and spacers from proven OEM alloys such as IN-718 and NiCrMoV, ensuring durability under 7FA gas turbine firing temperatures and stresses.
