G3 Series Auto-CPAP.

The quietest night we've ever engineered. Auto-titrating positive airway pressure with a humidifier that learns your environment, a flow generator tuned below a library whisper, and cloud adherence your clinician sees the morning after.

Feature 01 — Silent flow

The therapy
you don't hear.

A five-stage turbine damper, acoustically decoupled from the housing, and a mass-flow diffuser that breaks turbulence before it becomes sound. The G3 idles below 22 dB(A) — quieter than the rustle of a bedsheet.

  • 01Five-stage turbine damping with magnetic bearings
  • 02Acoustic decoupling via floating inner frame
  • 03Mass-flow diffuser breaks turbulence pre-outlet
  • 04Auto-quiet mode drops idle noise a further 3 dB
Feature 02 — Adaptive titration

AutoSense III.
Pressure that listens.

AutoSense III samples airway dynamics 100 times a second. When it senses a flow-limitation signature — before apnea takes hold — it nudges pressure upward within three seconds. When the airway relaxes, pressure steps back down so the therapy never feels heavier than it needs to be.

  • 01100 Hz airway dynamics sampling
  • 02Flow-limitation prediction ahead of event
  • 03Stepped pressure release on relaxation
  • 04Per-patient baseline learns over 7 nights

Feature 03 — HeatPath humidifier

Breath that feels
like home air.

A climate-line tube senses ambient temperature along its length and steers humidifier output to match. No rainout. No dryness. Just air that matches the room you're sleeping in — from a villa in Riyadh to a cabin outside Brussels.

  • 01In-tube climate sensing, end-to-end
  • 02380 mL tank for a full 9-hour night
  • 03Dishwasher-safe chamber, 3-click swap
  • 04Dry-mode cleanse cycle for patient safety
Feature 04 — Horizon OS

Adherence the clinician
sees at breakfast.

Every G3 unit reports usage, AHI, leak and pressure to Horizon OS — our FHIR-native adherence platform. Clinicians triage in a feed. Patients see progress in a tab. Insurers receive audit-ready reports without a single manual export.

At the bedside

A device that earns its
place by the lamp.

Most nights, our clinicians tell us, the G3 simply vanishes — sitting unnoticed on the bedside table, drawing no attention, producing no sound the patient registers. It's the quietest compliment a medical device can receive.

We trialled the G3 across our sleep lab and home-titration service for eighteen months. Patient-reported noise complaints fell to effectively zero, and the adherence feed changed how our nurses triage — we now intervene before a patient drops off therapy, not after.
