Marathon K280 Product Description

The Marathon K280 motor is a 3/4 horsepower motor that operates at two speeds, 1725 and 1140 RPM, and is designed to run on 460 volts. It is a belt drive fan and blower motor, which means it is commonly used in applications where air needs to be moved, such as in HVAC systems, industrial fans, and blowers. The motor's nameplate specifications provide important information about its capabilities and limitations. The horsepower rating indicates the motor's power output, while the RPM values indicate the two speeds at which it can operate. The voltage rating indicates the electrical supply the motor requires to operate, and the belt drive designation indicates that it is designed to be used with a belt-driven system. Belt drive fan and blower motors are commonly used in a variety of applications, including commercial and industrial HVAC systems, exhaust fans, and ventilation systems. They are also used in industrial processes that require air movement, such as drying, cooling, and conveying. These motors are designed to be durable and reliable, with features such as sealed bearings and heavy-duty construction to withstand the demands of continuous operation.
