This is an industrial belt-driven piston air compressor pump (compressor head) designed for heavy-duty air compression. It features a strong cast-iron body, oil-lubricated system, and high-efficiency cooling fins for long working hours and durability. The pump is built to be coupled with an electric motor or diesel engine and mounted on an air tank to form a complete air compressor.It delivers stable high-pressure airflow, low vibration, and reliable performance, making it ideal for auto workshops, vulcanizing shops, spray painting, fabrication, carpentry, and industrial use. The robust design ensures long service life, easy maintenance, and consistent output even in demanding environments.
