What is an electric air compressor？
An electric air compressor is the main component of an air supply system. It converts the mechanical energy of the prime mover (usually an electric motor) into compressed air pressure, making it the device responsible for generating compressed air. Currently, most electric air compressors on the market use oil lubrication. However, when oil-lubricated air compressors discharge air, some lubricating oil is also released, which can cause problems in braking and other systems. Our company has developed a new oil-free electric air compressor that can reduce such failures and improve system reliability.

Working Principle of Electric Air Compressor
The oil-free piston air compressor is mainly composed of components such as a crankcase, permanent magnet motor, crankshaft, connecting rod-piston assembly, valve plate assembly, cylinder, and cylinder head. The permanent magnet motor of the oil-free piston air compressor drives the crankshaft to rotate, which in turn drives the connecting rod-piston assembly to produce reciprocating motion in the cylinder. During this process, the working volume formed by the piston, cylinder, and cylinder head undergoes periodic changes. When the piston moves away from the cylinder head, the working volume of the cylinder increases, and gas enters the cylinder through the intake valve. When the piston moves towards the cylinder head, the working volume of the cylinder decreases, and the gas inside the cylinder is compressed, resulting in an increase in pressure. The compressed gas is then discharged from the cylinder through the exhaust valve. With each rotation of the crankshaft, the piston completes one cycle of suction, compression, and exhaust. This process continues in a continuous cycle.
