【Quiet & Powerful】 Mixed flow design combined with an EC motor that powers high-quality impellers makes this fan truly energy efficient. With only 27 watts of power but a strong airflow of up to 205 CFM, a very low noise level, and only 26.8 DB, this 4-inch inline ducting fan is silent. Lightweight ABS blades reduce the airflow resistance and add airflow by 40%.

【Intelligent Controller】The smart controller has multiple modes for operation, 10 fan speeds, is easy to program, and controls the humidity and temperature automatically. Easy to control over the fan speed, airflow, and many other elements, stabilizing and optimizing your growth environment.

【Temperature Regulation】 Inline fans help maintain optimal temperature levels by removing hot air and exchanging it with cooler air from the outside. This prevents overheating, which can damage plants and impede growth.

【Humidity Control】 Proper humidity levels are essential for plant growth. Inline fans assist in regulating humidity by exhausting stale air containing excess moisture and bringing in fresh, drier air. This prevents the development of mold and mildew, which thrive in humid conditions.

【Air Circulation】 Good air circulation is vital for plants to receive an adequate supply of carbon dioxide (CO2) and to facilitate the process of transpiration, where plants release water vapor through their leaves. Inline fans ensure that CO2 is evenly distributed throughout the grow space and that plants receive sufficient airflow to support their growth and development.

【Pest Prevention】 Proper air circulation can deter pests by creating an environment that is less conducive to their proliferation. Additionally, inline fans can help to remove airborne pests that may otherwise settle on plants and cause damage.
