Oil-lubricated compressors are a type of air compressor that relies on oil for lubricating the moving parts, particularly the pistons, crankshaft, and bearings, to reduce friction and dissipate heat. This lubrication increases the compressor’s efficiency and lifespan, making it more durable and suitable for heavy-duty applications. Oil-lubricated compressors are commonly used in industrial settings, workshops, automotive services, and construction.
