Hisummer 4x10 Register Booster Fan — 150 CFM, 10-Speed Quiet Operation with Temp Sensor

Enhance Comfort Where It Counts

Meet the Hisummer 4x10 register booster fan, designed to push heated or cooled air farther into upstairs spaces. It delivers up to 150 CFM with a precision angled air-guide grille that helps direct airflow forward, bringing more balanced comfort to bedrooms, nurseries, and attic areas.

In sleep-friendly settings, the unit runs exceptionally quietly—down to about 17 dBA in Sleep Mode—thanks to a three-part quieting system. The PWM motor, deep-groove bearings, and dynamically balanced blades minimize vibration for a calmer, steadier airflow.

Smart temperature sensing means the booster adjusts automatically as room conditions change. With a built-in start temperature for heating or cooling, you can set it once and let it respond, keeping the space comfortable without constant adjustment.

Installing is quick and clean. The booster fits 4x10 openings, uses a plug-in 100–240V adapter, and includes a 9.8-ft cord for tidy routing. Operating at only 6W, it’s designed for longer, energy-aware use in hot upstairs corners.

With 10 speeds, you can tailor airflow from a whisper to a solid breeze. PWM control ensures smooth ramping without sudden jumps, so the room feels right at every moment of the day.

Control is simple from bed or hallway: a 26-ft remote lets you adjust speed, mode, and timer, while the faceplate buttons provide quick local access. The built-in memory restores your last setup after power loss, with no app required.

Designed with busy homes in mind, safety is built in. A 5.8 mm anti-finger grille helps keep little hands safe, and a reinforced aluminum-alloy faceplate with thick ribs adds rigidity while supporting everyday activity. The housing is flame-rated for added peace of mind.

The unit’s premium flush-mount appearance sits neatly in the register opening, delivering a sleek, integrated look that blends into bedrooms and offices without drawing attention.
