Spider Farmer 6″ Inline Fan 402CFM With Speed Controller The ventilation system is responsible for maintaining optimal levels of temperature, moisture, and CO2. The activated carbon inside the filter acts as a sponge and will trap all particles other than air. This eliminates the odor, emissions. Powerful Inline Fan Mixed flow design combined with an EC motor ensures true energy efficiency, with only 62 watts of power but gives a strong airflow up to 402CFM, very low noise level only produces 32dB, this 6” duct fan is silent. Lightweight and balanced ABS blades reduce the airflow resistance and add airflow by 40%. The speed controller comes with a long wire length of up to 8.2ft which can place it out of the tent for easier control. 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 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.
