About This

• [Fix Hot Upstairs Rooms & Cold Corners] Tired of rooms that never feel right? This DEWENWILS register booster fan works with your HVAC system to push cooled or heated air farther into hard-to-reach spaces. With up to 140 CFM airflow, it helps reduce uneven temperatures—so upstairs bedrooms, corners, and distant rooms feel more balanced without forcing your HVAC to work harder.
• [Runs Only When Your HVAC Runs—No Wasted Energy] Built-in temperature sensing turns the vent fan booster on when airflow starts and off when it stops—so it works with your system, not against it. No need to leave it running all day or keep adjusting settings. Set it once, and it takes care of the rest.
• [Quiet Enough for Sleep, Strong Enough to Feel] Designed with dual ball-bearing motors for smoother, low-friction operation, this AC vent booster delivers noticeable airflow without disruptive noise. The display-off night mode keeps your room dark and undisturbed—ideal for bedrooms, nurseries, and nighttime use.
• [Simple Control—From Bed, Couch, or Anywhere] Adjust speed, modes, and timer with the remote or onboard buttons—no bending down to air vent fan. A clear display shows your settings at a glance, and built-in memory restores your last setup after power loss. No Wi-Fi, no apps—just simple, reliable control.
• [Drop It In, Plug It In, Done in Minutes] Fits standard 4” x 10” vents—just place it in and plug it in. No tools, no wiring, no remodeling. The long power cord gives you flexible placement, while the compact, flush design blends cleanly into your space. Please measure your vent size before purchase.
• [Safe & Durable for Everyday Family Use] The protective grille helps prevent fingers and small objects from entering, while the reinforced metal top is designed to handle daily foot traffic. Built for real homes with kids and pets—so you can use HVAC smart vent with added peace of mind.
