A low-pressure air compressor is a kind of compressed air equipment that works in a lower pressure range, and is usually used in some industrial application scenarios with relatively low compressed air pressure requirements. Here are some key information about low-pressure air compressors:

1.Definition: The output pressure of a low-pressure air compressor is typically between 2-5 bar (equivalent to 29-72 psi). In China, the output pressure of low-pressure air compressors is usually in the range of 0.2-1.0MPa.

2.Working principle: The working principle of a low-pressure air compressor is to discharge the air from the atmosphere into a container to form a certain amount of compressed air by driving the equipment, usually a motor. It usually consists of a cylinder, a piston, a compression chamber, and an exhaust pipe. When the motor starts, the drive device drives a piston to move back and forth in the cylinder, and the compression chamber in the cylinder gradually shrinks, so that the air is compressed. When the piston moves to the apex, the compressed air in the compression chamber is discharged through the exhaust pipe.

3.Peculiarity:

• High efficiency: In low-pressure conditions, low-pressure air compressors have a higher energy efficiency ratio, which can meet the demand for compressed air while reducing energy consumption.
• Energy-saving: Since only a low compressed air pressure is supplied, the power consumption is relatively low, which helps to save energy.
• Good stability: It has good operating stability under low-pressure working conditions, and can continuously and stably provide the compressed air required for industrial production.

5.Selection guide: When selecting a low-pressure air compressor, factors such as working parameters, pressure range, durability and maintenance cost should be considered to ensure the efficient operation and long-term reliability of the equipment.

Because of its high efficiency, energy saving and stability, the low-pressure air compressor has good performance under low-pressure working conditions and is suitable for a variety of industrial fields. With the progress of technology and the growth of market demand, the application of low-pressure air compressor will be further promoted and developed.
