A Spacer is a mechanical component that is designed to create a gap between the fan and the engine or radiator. The spacer is typically a cylindrical or rectangular-shaped component made of metal, plastic, or composite materials. In addition to creating space between the fan and other components, fan spacers can also improve the cooling efficiency of the engine. By creating additional space between the fan and the radiator, the spacer allows for more air to flow through the radiator and over the engine, improving the engine's cooling performance.Attributes:• Reduces vibration, which can improve the efficiency of the machine and reduce wear and tear.• Reduces the risk of damage and increases the lifespan of the engine.Applications:A Spacer is primarily used in cooling systems to provide clearance between the fan blades and other components in the engine.
