Why trust a certified ADAPT BG technician instead of a random "concentrator technician" from an ad on a classifieds site?

We will repair your oxygen concentrator in the case of:


  • Overheating;

Our technicians will also measure your O2 device's oxygen concentration with a specialized instrument.

Trusting not-certified technicians is risky, especially after the shocking cases of "repaired" concentrators that eventually end up in our service centers. The most recent cases involved Kroeber concentrators that were so "professionally repaired" that the thermal sensor was remade with a wire bypass that would rather set a patient's home on fire than provide actual protection...
