Air Fx – Product Information

Air Fx is a high-precision caloric air irrigator system developed by Interacoustics for vestibular (balance) testing. It is primarily used in clinical audiology and neuro-otology to evaluate the function of the horizontal semicircular canals in the inner ear during caloric testing.

Product Overview

Air Fx delivers controlled warm or cool air into the external ear canal to stimulate the vestibular system. This process helps clinicians assess balance function and detect possible vestibular disorders such as dizziness or vertigo.

The device is designed to provide accurate, stable, and repeatable caloric stimulation, making it suitable for detailed diagnostic evaluation of bilateral inner ear function.

Key Features

• Precise air temperature control for both warm and cool stimulation
• Controlled airflow directed into the ear canal for consistent testing
• Used to evaluate vestibular-ocular reflex (VOR) responses
• Compatible with VNG/ENG systems for eye movement recording
• Built-in otoscope and LED illumination for safe ear inspection
• Integrated temperature sensor ensures stable and accurate output
• Can be used as a standalone device or integrated with software systems

Clinical Function

Air Fx works by changing the temperature inside the ear canal, creating a thermal response in the inner ear fluid. This triggers eye movements (nystagmus), which are then recorded and analyzed to assess vestibular function.

It is widely used in:

• Dizziness and vertigo evaluation
• Vestibular function testing
• Balance disorder diagnosis
• Neuro-otological assessment

Technical Highlights

• Airflow: controlled and consistent delivery
• Temperature range: warm and cool stimulation modes
• High accuracy and stability for clinical reliability
• Designed for safe use in routine vestibular diagnostics
