Power Supply External 90 Watt Power Supply 


There are two different power supplies for the Air10 devices. Please make sure you double check the name of your machine, to make sure you get the right power supply. 

  • Item 37474 - AirStart, Airsense 10 and AirCurve ST and ASV machines
  • Item 37344 - AirCurve ST-A and RPS II machines 

The Power Supplies are an external power device that supplies power to your Air10 series machines. Both of the power supplies include the power device itself and a connecting cord.

AirStart/AirSense and AirCurve ST-A

ResMed's AirStart, Airsense 10 and AirCurve ST and ASV machines now have a new lighter power cord, and is item 37474. This lighter cord will be especially handy if you take the machine traveling with you, as this supply is significantly lighter than the previous. However, the AirCurve ST-A Machines will still use item 37344.

These machines are the ResMed manufacturer's latest lines of CPAP and BiLevel devices. There are six machines in the series, all of which offer top-notch comfort features and the blend of durability and performance you've come to expect in a premier machine.

The AirSense 10 and AirStart, are one of the most popular CPAP and APAP machines out on the market today. They are very quiet and user friendly. In saying this, make sure you double check which cord you do need, the AirSense 10 and AirStart normally have a black exterior, the AirCurve will normally have silver on the machine. However make sure to read the label on the front of the machine to be sure before ordering. 

Connection Cord

The item includes a Connection Cord as well as the Power Supply itself. These are compatible with the machines mentioned above. They us a 90 watt power supply.
