More importantly, they have high power output, sustained high torque and powerful motive force. As a result of these superior characteristics, they can drive huge volume of air exchange for the purpose of cold and hot air regulation in various equipment and systems. Models of higher speed and larger airflow volume than AC motor are also available. Wide range of speed regulation and the intelligent adjustment by the open circuit and closed circuit which make the fans control the needed air volume accurately automatically. DC blowers are especially compatible for air flowing, ventilation, air conditioning, refrigeration and automobile industry etc. DC brushless evaporator blowers with single-speed version, double-speed version or variable speed version and outer coverings with single or double housing are available. No carbon brush Low power consumption Super long service life Maintenance-free Environment-friendly Short circuit protection Over-current protection Over-temperature protection Over-voltage protection Under-voltage protection Locked-rotor protection
