<h2>Product Description</h2> <p>A quiet register fan system designed to improve airflow coming from your central AC or heating system. With this fan, you can boost the amount of cool or warm air exhausted from registers where airflow is traditionally weak. This will improve your rooms' comfort level while reducing energy costs. It features an onboard smart controller programmed with cooling and heating triggers, timer and cycle programming, and 10-level speeds. You can access these controls and more remotely by connecting to the AC Infinity app using Bluetooth. The register booster fan is finished with a premium aluminum front plate with CNC-machined detailing that gives a clean aesthetic to your register.</p> <h2>Intelligent Programming</h2> <p>The onboard controller features active thermal monitoring, using temperature triggers to activate this register fan in response to crossing heating or cooling thresholds. Minimum baseline levels keep the register fan running at low speeds for consistent airflow, while timer and cycle modes add custom on-demand activation. Securely connect to the AC Infinity app via Bluetooth to utilize automation capabilities from anywhere throughout the day. Remotely access your devices, unlock advance programs, set alarms and notifications, view historical charts, and export CSV data.</p> <h2>Heavy-Duty Performance</h2> <p>The register booster fan system utilizes a high-performance DC motor controlled using PWM (Pulse Width Modulation). This technology enables the dual fans to run smoothly at extremely low RPM speeds without generating motor or electromagnetic noises. The motor houses dual ball bearings rated at 67,000 hours and are certified by CE and RoHS.</p>
