Burlo Fans & Molds offers plastic motor fans designed to meet the needs of the motor repair industry. Each fan comes with a series of interchangeable hubs to facilitate a wide range of shaft sizes. The number of hubs required is greatly reduced as each hub will fit two fan sizes. Each fan size has a blank bore or "0" hub, which can easily be machined for non-standard shaft sizes. Hubs can be inserted in the fan from either the concave or convex surface of the fan and snap firmly into a locking mechanism. Both the fan and hub are manufactured from polypropylene and made in Canada.
