AirJet™ Technology
Cleaning Beyond Where Bristles Can Reach
AirJet™ combines airflow, liquid and sonic motion to create a high-density microbubble stream that travels along teeth and into hard-to-reach spaces.
WHY AIRJET™ EXISTS
Bristles clean through physical contact.
But between every two teeth is a narrow interdental gap — a space bristles cannot fully enter or sweep.
That gap is where AirJet™ comes in.
What if cleaning doesn't rely solely on brush bristles?
WHAT IS AIRJET™ TECHNOLOGY?
A New Way to Clean Beyond Bristles.
AirJet™ is RANVOO’s proprietary fluid-dynamics cleaning system, developed to extend cleaning beyond direct bristle contact and into the gaps between teeth.
Coandă Brush Head
The specially engineered brush head uses the Coandă Effect to guide microbubble-rich flow along tooth contours and toward the narrow spaces between teeth.
Variable-Speed DC Air Pump
The high-speed air pump continuously injects air into the liquid stream, generating dense microbubbles and driving fluid movement through the brush head.
How AirJet™ Works
From Air Intake to Interdental Flow.
Every AirJet™ toothbrush uses a dedicated air pathway built into the handle and brush head. Air is drawn in, pressurized, and delivered through the hollow brush head, where it mixes with liquid and toothpaste inside the mouth to create a microbubble-rich cleaning flow.
Air Enters the Toothbrush
A dedicated air inlet at the base of the toothbrush continuously supplies air to the internal AirJet™ system.
The Air Pump Pressurizes the Flow
The internal pump creates a controlled stream of air and sends it toward the brush head through the sealed airway.
Air Travels Through the Hollow Brush Head
Unlike a conventional solid brush head, the AirJet™ brush head contains a dedicated hollow pathway that carries airflow all the way to the outlet near the bristles.
Air Meets the Oral Environment
Once inside the mouth, the airflow mixes with saliva, water, and toothpaste around the brush head, forming a microbubble-rich fluid flow.
Flow Is Directed Into Interdental Gaps
The brush head geometry helps guide the flow around tooth contours, allowing cleaning action to extend into areas that bristles have difficulty fully reaching.
Fluid That Reaches Further
AirJet™ creates a fine, high-density bubble flow that moves through narrow spaces and around tooth contours.
Smaller
Moves through tight interdental gaps.
Dispersed
Spreads through the surrounding liquid instead of moving as one single jet.
Mobile
Travels around curves and beyond direct bristle contact.
