【Enhanced Energy Efficiency】Boost the performance of your existing heating and cooling system by improving air circulation for quicker and more even temperature distribution, keeping you comfortable and saving energy.

【Intelligent Controls】Benefit from a built-in temperature probe, the fan reacts intelligently. It runs if the airflow’s temp. falls below or rises above the cooling or heating trigger’s setting respectively. A programmable LCD controller with 6 buttons offers intuitive operation. Note: The set temp. only triggers the fan to work and is NOT your room temp. or desired temp.

【High-Powered Airflow】A maximum airflow of 180CFM surpasses other brands’ by 50%, providing higher airspeed and further coverage, making it great for larger spaces. Choose from 10 fan speeds or use the TURBO function for the highest speed with just one press.

【Versatile Four-Way Vent Grille】Designed to fit 4’’x12’’ registers on either the wall or the floor. The 4-way vent grille is uniquely crafted at a 45° angle to facilitate airflow in all four directions, optimizing circulation in any room.

【Where To Use】This booster fan is specifically engineered for aging central air systems, situations where registers are distant from the main HVAC unit, or cases where multiple rooms rely on the same HVAC unit.
