ResMed AirFit F40 QuietAir Elbow

The genuine ResMed QuietAir elbow system for the AirFit F40 full face mask. More than just an elbow, this part combines the quick-release elbow, the short connector tube, and the QuietAir diffused vent in one assembly — so if your elbow has cracked, the swivel has loosened, or therapy has become noisier than it used to be, this single part restores quiet, comfortable airflow without the cost of a new mask.

Key Features

• QuietAir diffused venting — exhaled air is dispersed gently through many small openings rather than one stream, softening both the noise and the breeze felt by your bed partner.
• Whisper-quiet 20 dBA — ResMed rates the QuietAir vent at just 20 dBA for noticeably calmer nights.
• Short tube included — the assembly comes with the short connector tube that links the elbow to your main air tubing, reducing tube drag as you move.
• Quick-release elbow — press the clips on either side to disconnect from your tubing in one motion, so you can get up without removing the mask.
• Genuine ResMed part — built to the original specification for correct venting and a secure fit.

Elbow System or Vent Ring — Which Do I Need?

The F40 has two related replacement parts. This QuietAir elbow system is the complete assembly — elbow, short tube and vent — and is what you need if the elbow itself or the short tube is worn or damaged. If your elbow is fine and you only need to refresh the small diffuser insert, the cheaper AirFit F40 QuietAir vent is the part to choose.

Who Is This For?

Ideal for existing AirFit F40 users whose therapy has grown louder, whose vent has discoloured or clogged, or whose elbow swivel or short tube has worn or loosened. It fits the AirFit F40 only — it isn't compatible with earlier F-series masks like the F20, F30 or F30i, which use different elbows.
