BIOWIND Quiet Register Booster Fan – 4x12 Duct, 10-Speed Remote & Thermostat

Boost Comfort with a Quiet, Smart Vent Booster

Meet the BIOWIND Quiet Register Booster Fan, a discreet upgrade that extends airflow from wall or floor vents without adding bulk to your space. Built with a premium anodized aluminum frame and CNC-machined details, its slim profile blends with modern interiors while delivering practical airflow improvements for rooms that often feel stuffy or uneven.

Smart control that adapts to your day

The unit pairs a programmable LED controller with a precise temperature sensor, enabling automatic adjustments to move warm or cool air to the right rooms at the right moments. This smart behavior supports balanced temperatures throughout your home without constant manual tweaks.

• Remote ease: adjust fan speed from 0 to 10 levels with the included remote for tailored airflow and quiet operation.
• Thermostat-driven comfort: the integrated sensor helps align vent activity with your HVAC schedule for a steadier feel.
• Energy-aware design: enhanced airflow from the booster can improve your existing system’s effectiveness while using minimal extra energy.

Designed for everyday life

The compact, plug-and-play design fits most 4x12 openings. The neck fits inside the duct with the face frame resting on the surface, simplifying installation. Key specs include 6W power, 120 CFM airflow, and 18 dBA noise, all contributing to a subtle presence in the room.

• Easy installation: comes with a wall adapter for quick setup without complicated wiring.
• Post-HVAC airflow: the fan may run briefly after the system turns off to help pull residual air into the room.
• Affordable upgrade: a simple, cost-effective way to improve air distribution without major remodeling.

Please measure your duct opening before ordering to ensure a proper fit. The listed size refers to the actual duct opening; the neck fits inside while the face frame rests on the surface for a clean installation.
