Overview

The Dial 6718 is a hollow blower shaft designed as a direct replacement part for evaporative cooler and blower systems. This shaft measures 3/4 inches in diameter and 24 inches in length, giving it a solid fit across a wide range of residential and commercial blower applications. HVAC technicians and maintenance professionals rely on blower shafts like this one to keep air-moving equipment running at peak performance. The hollow construction of the Dial 6718 reduces overall weight without sacrificing structural integrity. That means less strain on the motor bearings and drive components over time. A lighter shaft also makes installation faster and easier, which matters when you are working on a tight schedule. The rust-resistant design helps extend service life, especially in environments where moisture is present. Evaporative coolers and blower assemblies are constantly exposed to humidity and outdoor conditions, so corrosion resistance is a key factor in long-term reliability. The 3/4-inch diameter shaft provides the strength needed to handle the rotational loads typical of blower motor applications. The 24-inch length makes this shaft compatible with a broad selection of blower models, reducing the need to source multiple parts for different units.
