ClimateLine™ Heated Tubing For S9 Series



Masks Size Guide

ClimateLine™ Heated Tubing for Resmed™ S9 series. It uses a built-in mask temperature sensor to reach relative humidity at the mask. Sensors inside and outside CPAP machine closely monitor changes in humidity and prevents condensation from forming inside the tube. ClimateLine™ is more flexible than most tubing available in the market. Exclusive to Resmed, ClimateLine tubing is 40% lighter, 20% thinner, and takes up 35% less space. Heated tubing only, machine sold separately. 

Additional Info

Virtually eliminates rainout (condensation) in the tube, which can occur when the temperature drops during the night. Because the system measures the temperature at the mask, it will remain at the preferred setting, regardless of changes in ambient temperature or humidity. 

  • Length: 6'5" ft (78 in)
  • Diameter: 15mm
  • ClimateLine™ Heated Tubing should be replaced every 3-6 months or as needed
