Description

【Powerful Inline Fan】Mixed flow design combined with a EC motor that powers high-quality impellers makes this fan truly energy efficient than a traditional line fan. 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” exhaust fan is silent. Lightweight ABS blades reduce the airflow resistance, add airflow by 40%.

【Temperature Regulation】 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.
