QUIET & POWERFUL: The mixed flow design combined with an EC motor that drives high-quality impellers makes this fan particularly energy efficient. With only 27 watts of power and a strong airflow of up to 205 CFM at a very low noise level of just 26.8 dB, this 4-inch exhaust fan is almost silent. Lightweight ABS blades reduce air resistance and increase airflow by 40%.
DURABLE: Made of sturdy plastic housing for superior durability, IP42 rated, making it particularly resistant to dust and liquids. It works well even in harsh environments. The exhaust fan is ETL/FCC listed.
INTELLIGENT CONTROLLER: The intelligent controller has multiple operating modes, 10 fan speeds, is easy to program and automatically controls humidity and temperature with 4 simple settings and alarms, making it easier for you to keep the room at the optimal temperature and humidity.
DAISY CHAIN PROGRAMMING: Two 4-inch exhaust fans can be daisy-chained together to share the same controller. The long cable design makes fan connection and installation much easier.
VERSATILE APPLICATIONS: Designed to increase air circulation in cooling and heating systems, the 4 inch inline duct fan is a great option for grow tents, closets, storage rooms, kitchens, bathrooms, basements and more.
