Amarillo Right Angle Fan Drive Model 85 2:1 Ratio

The Amarillo Model 85 Right Angle Fan Drive is a robust, heavy-duty gearbox designed for industrial cooling tower and fan applications. Manufactured by Amarillo Gear Company, this unit features a 2:1 gear ratio, making it ideal for reducing input speed from high-RPM motors to lower output speeds suitable for fan blades in air-cooled heat exchangers, cooling towers, and similar systems. Key benefits include high torque transmission, reliable performance in harsh environments, and a cast iron housing that provides durability and corrosion resistance. It supports a service rating of 50 HP at 1750 RPM input, with a 1.0 service factor, ensuring efficient operation under continuous loads. Advantages over similar products include superior gear design for minimal backlash, easy maintenance with accessible lubrication points, and compatibility with standard ISO 220 oils. Drawbacks may include its weight, which requires sturdy mounting, and the need for periodic oil changes to prevent oxidation. This specific unit appears used or refurbished based on image analysis, showing fresh paint, minor surface wear, and protective wrapping on the shaft. No parent/child assets are visible. Applications span petrochemical, power generation, and HVAC industries. For optimal performance, follow the manufacturer's lubrication instructions to maintain protective oil films.
