    DC Blowers

    Operate these blowers with a DC power source, such as your vehicle battery. Use them for equipment cooling, material conveying, drying, ventilating, and exhausting.
    Note: Airflow depends on the resistance created by ductwork. This resistance, known as static pressure (SP), is measured in inches of water.
