## Features

- 2026 Fan Stability Upgrade: Built with dynamic fan balancing, motor start-up verification, and noise & vibration screening to support smoother airflow, quieter operation, and long-term reliability.
- Quiet Register Booster Fan: A quiet fan system designed to improve airflow from wall and floor vents in HVAC systems, helping increase home comfort. Built with a premium anodized aluminum frame and CNC-machined details, it offers a sleek, flush, and modern appearance that blends seamlessly with your home decor.
- Eliminate Uneven Room Temperatures: The Biowind smart register vent features a programmable LED controller and a high-precision temperature sensor that works with your HVAC system. It automatically turns the vent fan on or off to deliver warm or cool air to rooms at the right time, helping maintain balanced temperatures throughout your home.
- New Upgraded Remote Control: Easily adjust the fan speed (0–10 levels) with the remote to meet diverse user needs and achieve the perfect balance between airflow performance and quiet operation. Control your comfort without getting up, simple and convenient.
- Energy-Saving & Cost-Effective: This vent booster fan is more energy-efficient than traditional air-conditioning or cooling devices. By enhancing airflow and circulation, maximize the heating or cooling from your HVAC system with minimum energy. Even after your HVAC system shuts off, the fan continues running briefly to pull remaining warm or cool air into the room—helping you save energy and reduce electricity costs.
- Compact & Easy to Install: The Biowind smart register booster fan features a compact design that is easy to install and move when needed. Fits ONLY 4" x 12" duct opening (cutout) | Rated Power: 6W | AC Input: 100 to 240V | Airflow: 140 CFM | Noise: 16 dBA. Includes wall adapter, plug and play for quick setup.
- Affordable Comfort Upgrade: Compared with large air conditioning or cooling systems, booster fans are a simple and affordable solution for improving airflow and indoor comfort, making them accessible for most households.
- Please Measure Before Ordering: Please measure the duct opening (cutout) before ordering, not the old vent cover. The listed size refers to the actual duct opening in the wall or floor. The neck of the register booster fan fits inside the opening, while the face frame sits on top of the wall or floor surface. Measuring correctly helps ensure the best fit and helps avoid unnecessary returns. Listed Size: 4" × 12", Neck Size: 9.72" × 3.93", Face Size: 13.77" x 5.51", Neck Insertion Depth: 1.96".
