    Description

    Smart Control through the Spider Farmer App

    Manual Mode

    The inline fan speed can be set between 25% and 100%.
    To turn off the fan, tap the toggle switch below the speed ring. 
    Close CO2 Device: A GGS power strip is required.
    Assign an outlet as a CO₂ device (intake or exhaust). If it’s an intake device, it will automatically turn off when the fan is running.

    Time Slot Mode

    Start Time / End Time: Set when the fan should turn on and off automatically.
    Operation Speed: Fan speed during active time.
    Standby Speed: Fan speed during off-time. It must be lower than the operation speed. If not set, the fan stays off during standby.

    Cycle Mode

    Start Time: When the fan starts its first cycle.
    Run Time: Duration the fan stays ON in each cycle.
    Closing Time:Duration the fan stays OFF in each cycle.
    Execution Times: Number of ON/OFF cycles to repeat.
    e.g. Start at 12:00-Run 1h-Off 1h-Repeat 2 times
    12:00-13:00 ON, 13:00-14:00 OFF, 14:00-15:00 ON, 15:00-16:00 OFF.

    Environment Mode

    Two modes available: temperature-priority and humidity-priority. When both temperature and humidity are out of target range, temperature takes precedence.

    【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 exhaust fan is silent. Lightweight ABS blades reduce the airflow resistance and add airflow by 40%.

    【BUILT TO LAST】Made of heavy-duty plastic housing for superior durability, IP42 rated, making it highly resistant to dust and liquids, and performs well even in harsh environments. The exhaust fan is ETL/FCC listed.

    【INTELLIGENT CONTROLLER】The smart controller has multiple modes for operation, 10 fan speeds, is easy to program, and controls the humidity and temperature automatically with 4 easy settings and alarms which makes it a breeze to keep your space at the optimal temperature and humidity.

    【DAISY CHAIN PROGRAMMING】2 of 4-inch exhaust fans can daisy chain together to share the same controller, the long corded design greatly facilitates the fan connection and installation.

    【WIDE APPLICATIONSL】Designed for air circulation boosting of cooling and heating systems and air-circulation. The 4-inch Inline duct fan is a great option for growing tents, closet, storage rooms, kitchens, bathrooms, basements, and more.
