Yes, many of our clients have travelled all over the world for business and leisure. Our current line of PAP therapy units adjusts to 100 – 240 volts (50 – 60 Hz). All that is required is an outlet adapter. Clients are encouraged to take their unit as part of their carry-on to ensure it is not damaged. The X-ray machine will not damage your unit, but it may be inspected by security. It is best to carry a copy of your prescription when travelling and to directly contact the airline should you intend on using your PAP therapy equipment in flight.
