Equipment Matching Mounted Type

• Ultra-Quiet Design

  This simple and portable oil-free scroll air compressor can be easily mounted on various equipment requiring compressed air. The unit does not require any lubricating oil, making it stable and reliable. It requires minimal maintenance, with only one lubricant addition per year, and the only consumables are the air filter element and the sealing ring.

Principle of Compressed Air in our Oil-free Scroll Air Compressor

• Structure

  The oil-free scroll air compressor comprises two overlapping scroll screws ?C a fixed screw and a rotating screw. The gap between the screws forms a compressed space.

• Inhalation Process

  When the rotating screw begins to rotate, air enters the compressed space through the intake port of the compressor. During this process, the movement of the scroll screw sucks the air in and gradually pushes it towards the center.

• Compression Process

  With the movement of the rotating screw, the air is pushed into an increasingly smaller compression space, causing the air to be compressed. This is achieved through the relative movement of the scroll screws and the reduction of the gap.


• Emission Process

  Once the air is compressed to the required pressure, it is discharged through the outlet of the compressor. In this process, the movement of the scroll screw pushes the air towards the outlet of the compressor.

• Oil-free Principle

  The key feature of oil-free scroll air compressors is that they do not require lubricating oil to cool and lubricate the scroll screws. Instead, they use a special coating material, such as a polymer coating, to reduce friction between the scroll screws and ensure an efficient compression process.
