【Functions; Applications】Featuring an airflow of 260 CFM and air out ventilation type, this Ventilator fan is designed for use in damp crawl spaces, basements, attics, and garages to effectively reduce humidity. It enhances air circulation to prevent condensation and wood rot, and it's also useful for exhausting vent radon gas, treating wood gases and odors, and preventing their entry into living spaces.

【Key Features】Equipped with a built-in dehumidistat and freeze protection thermostat, this High-Flow Powered Ventilator Fan automatically turns ON/OFF based on the set Humidity % Level within a humidity range of 5%-80%RH. The Dehumidistat control is disabled if the freeze protection thermostat detects low outdoor temperatures (35°F/3°C), ensuring optimal performance in different weather conditions.
