Nanjing Oil-Free Compressor Co., Ltd. focuses on the research and development of oil-free medium and high pressure air compressors, committed to producing air compressors with higher cost-effectiveness, superior performance, and lower energy consumption. Oil free high-pressure air compressors widely used in various industries, such as PET bottle blowing, pharmaceutical, food, beverage production, etc., with increasing customer demand.
Our advantages:
Higher cost-effectiveness in the market:
Low installation and maintenance costs, low energy costs, a total of 14 valves from the 1st stage cylinder to 3nd stage cylinder, optimized valve quantity design, and low speed
Low energy cost
The "L-type" compressor's energy consumption of the first stage operation accounts for more than 45% of the total energy consumption, and the use of vertical free-fall motion can better reduce the energy consumption and extend component life
High energy efficiency
All components and spare parts have a long service life, low wear, and low speed: 340 rpm to 580 rpm
Low maintenance cost
The machine has a simple structure and few vulnerable parts, making it easy to come into contact with the machine for maintenance. The maintenance time is shorter and the effect is better
Easy to install
Due to the use of shock-absorbing devices, there is no need to lay a special foundation, installation is simple and fast, and the investment cost of installation is low
