Medium and high pressure air compressors refer to equipment that can compress air to medium or high pressure. Usually, multi-stage compression is used to gradually increase the air pressure through multiple cylinders. The pressure range of 30-40 bar belongs to the medium and high pressure category. This type of compressor is usually used in industrial applications that require higher pressure, such as PET bottle production, blow molding, beverage packaging, etc.

1. High energy efficiencyLong component life, low wear and low speed: 340 rpm to 580 rpm, few wearing parts, easy accessto the machine for maintenance.
2.High reliability and easy maintenance.
3. Short maintenance time and good results.
4. Due to the use of anti-vibration devices, there is no need to lay a special foundation, and theinstallation is simple and fast, it can reduce the investment cost of installation.
