Description

【Powerful Inline Fan】Mixed flow design combined with an EC motor ensures truly energy efficiency, with only 27 watts of power but gives a strong airflow up to 205 CFM, very low noise level, only produces 26.8 dB, this 4” duct fan is silent. Lightweight and balanced ABS blades reduce the airflow resistance, and add airflow by 40%. 

【Temperature Control】 By extracting hot air generated by grow lights and other equipment, inline fans prevent the indoor environment from becoming too hot. This helps to maintain optimal temperatures for plant growth, preventing heat stress, which can damage or slow down plant development.

【Humidity Control】 Proper airflow facilitated by inline fans aids in regulating humidity levels. Excess humidity can lead to issues such as mold, mildew, and pests, which can harm plants. Inline fans help to mitigate these risks by promoting air exchange and reducing moisture buildup.

【Odor Control】In setups where plants emit strong odors, inline fans equipped with carbon filters can effectively remove unwanted smells. This is particularly important for maintaining discretion and preventing odors from escaping into surrounding areas.

【Pest Prevention】Adequate airflow can deter pests by creating an environment less conducive to their survival. Additionally, inline fans can be used in conjunction with other pest control measures to maintain a healthy growing environment.

Q & A

Will a Smart Controller work with this set up even though its not included? Also will a different brand smart controller from a local store work with controlling? Chris asked on June 3, 2023

The fan can only be controlled using the included speed controller. And we have not tested using a different brand smart controller to control the fan, so we cannot provide a definitive answer at this time.
