Why Choose an Oil-free Medium Pressure Screw Air Compressor? Benefits and Applications Explained
A medium pressure micro oil screw air compressor is a type of rotary screw air compressor designed to operate in the medium pressure range, typically between 7 to 25 bar (100 to 375 psi). This compressor uses a pair of interlocking helical rotors to compress the air, and the term “micro oil” refers to the lubrication system that involves a small amount of oil to reduce friction and wear while maintaining high efficiency.
The key difference between micro oil and conventional oil lubrication systems is that the oil is carefully metered and typically used in minimal quantities. This helps achieve optimal lubrication without causing excess contamination of the compressed air. The micro oil design is a balanced approach, providing the benefits of oil-lubricated systems, such as reduced friction and better heat dissipation, while minimizing the amount of oil in the compressed air, thus ensuring cleaner air output for sensitive applications.
Micro-Oil Lubrication Technology Principles
Micro-oil lubrication in screw compressors involves injecting a small amount of oil into the compression chamber. The oil serves two primary functions: lubrication and cooling. By coating the screw rotors and internal parts, the oil reduces friction, which increases efficiency and extends the lifespan of the compressor.
Unlike traditional oil-injected screw compressors, which may release larger quantities of oil into the compressed air, micro oil compressors are designed to minimize the amount of oil in the output air.
