Medium Pressure Oil Free Screw Air Compressor

A medium-pressure oil-free screw air compressor is a type of air compressor that is designed to operate at a medium pressure range, typically between 2 bar (29 psi) to 10 bar (145 psi), and without the use of oil as a lubricant. This makes it ideal for applications that require the production of clean, oil-free compressed air, such as in the food and beverage industry or in medical and pharmaceutical applications.

The oil-free screw compressor works by using two rotors or screws that mesh together and rotate in opposite directions. As the rotors turn, the air is drawn in and compressed between the two screws. The compressed air then flows through a series of intercoolers and final coolers to be cooled down and dried, and then it is released into the system at the desired pressure.

The benefits of using a medium pressure oil-free screw air compressor are numerous. Firstly, these compressors produce clean and dry air, which is vital for many applications. Secondly, they are designed to be highly reliable and have a long service life. They are also energy-efficient and feature a low consumption of cooling water, making them cost-effective to run.

One of the main disadvantages of medium-pressure oil-free screw compressors is their upfront cost, which is typically higher than traditional oil-lubricated compressors due to their more complex design and manufacturing process. Additionally, proper maintenance is required to ensure optimal performance, and this may increase the cost of operation.

The new machine can save energy by 15%-20% compared with the piston air compressor. After the piston ring and cylinder are worn out, the energy saving is 30%-40% compared with the piston air compressor. The electricity cost saved after running for 2 years is equivalent to the purchase cost of the machine.

Applications for Industrial Oil-Free Air Compressors

Oil-free compressed air is a powerful production method for companies that need to produce products with air purity and product safety in mind. Oil-free compressors are always ISO Class Zero certified and provide a 100% oil-free air supply for sensitive applications. Some industry application examples include:

 

  • Automotive: Oil-free compressed air creates high-quality automotive paint finishes in a smooth process.
  • Food and beverage: The oil-free approach creates healthier foods while also eliminating any possibility of oil contamination.
  • Chemical:  The chemical industry benefits from oil-free air compressors as these machines increase purity, reduce waste and increase safety.
  • Electronics: Oil-free methods are critical for electronics as they provide uninterrupted control systems in ultra-clean conditions for the production of delicate devices such as motherboards.
  • Pharmaceuticals: Oil-free air compressors reduce the risk of oil contamination in pharmaceutical products and help improve production efficiency.

When you want to produce products in environments where oil contamination can cause equipment damage or lead to costly damage and recalls, oil-free air compressors are the perfect solution to achieve the highest standards of air purity.
