Enroute at FL350; we had a LEVEL 3 AIR MANF 3 FAIL and the air system controller automatically shut off the number 3 bleed air valve. We ran the QRH procedure and the alert went away. The QRH procedure directed us to land at nearest suitable airport. We were able to operate the number 3 engine at a reduced power setting and keep the alert from reappearing. We were abeam ZZZZ and nearly overhead ZZZ so after checking the weather; we decided ZZZZ was the better choice. We advised ATC; ran all the normal checklists and flew the ILS to RWY XXR at ZZZZ. We landed uneventfully; taxied clear of the runway and had the Fire Department check out our right wing and around the airplane. They noted everything appeared normal with no visible damage. We taxied in to the ramp and shut down and wrote up the malfunction.
Air carrier Captain reported a LEVEL 3 AIR MANF 3 FAIL at FL350 and diverted to the nearest suitable airport.
