This type of compressor utilizes a belt and pulley system to transfer power from an electric motor to the pump that compresses air. This setup often features a large flywheel attached to the pump’s crankshaft, storing kinetic energy and smoothing out the pump’s operation. A common example is its use in workshops and garages to power pneumatic tools.
The belt-driven design offers several advantages, including increased durability due to the flywheel’s ability to absorb shocks and vibrations, and the flexibility to adjust compression output by changing pulley sizes. Historically, these systems were prevalent in industrial settings and continue to be valued for their robust construction and maintainability. Their relatively simple design also contributes to ease of repair compared to direct-drive counterparts.
