Airwoods CFAU90 Series Ultra-Slim Smart Energy Recovery Ventilator

Maximize your spatial efficiency. With an incredibly compact 9-inch (229 mm) thickness, the CFAU90 series is specifically engineered to fit seamlessly between ceiling joists. It completely eliminates the need for drain lines and offers both Top Port (CFAU90T) and Side Port (CFAU90S) configurations, making it the ideal solution for restricted spaces and fast-track retrofits.

Say goodbye to complex and time-consuming field adjustments. Powered by high-efficiency, thermally protected backward-curved centrifugal fans, this ERV features 100% electronic speed balancing. It delivers precise airflow delivery without the hassle of installing or adjusting traditional balancing dampers, significantly reducing labor costs for installers.

Breathe healthier air while lowering your energy bills. The system utilizes a cutting-edge 5th-generation thinner membrane that provides superior thermal conductivity, achieving an exceptional sensible and latent temperature efficiency of 80% to 92%. Furthermore, the core is strictly mildew-resistant and fire-retardant to guarantee long-term safety and indoor air quality.

Experience an air system that thinks for you. By integrating optional smart sensors, the CFAU90 continuously monitors your indoor environment. When CO2 levels or humidity exceed your custom setpoints (800-2000 ppm for CO2, 50-100% for humidity), the unit automatically overrides its current setting and runs at maximum speed to rapidly restore fresh air, then auto-returns to the previous mode.

Ensure uninterrupted operation during harsh winters. The unit comes standard with an Auto Defrost function that automatically activates below set temperatures, utilizing optimized airflow cycles to protect the heat exchange core. For extreme cold regions, it is "Electric Heater Ready"—intelligently controlling an optional in-duct heater based on outdoor temperatures with built-in safety interlocks.

Take total command of your indoor climate. The optional LCD smart controller offers 4 running modes (Continuous, Intermittent, 4-Period Schedule, Manual) and allows you to set independent supply and exhaust fan speeds for a 7-day schedule. The intuitive display shows outdoor temperature, active modes, and a filter replacement countdown (60-180 days). With Wi-Fi readiness, you can monitor and control the system from anywhere via the mobile app.
