Narrative:
During cruise at FL290 the pressurization unit failed on aircraft. The emergency pressurization opened and aircraft remained pressurized. I asked center for a lower altitude and was advised they were unable unless I declared an emergency. I did and got lower. At 11000 ft MSL, I advised we were ok. Center said no problem and we returned to home base.
