Dry oil-free screw compressor is an efficient and reliable compressor type that uses a pair of intermeshing screws to compress air or gas. It is called "dry" because no oil is used to lubricate the screw during the compression process, in contrast to "wet" or "oil-lubricated" screw compressors. The following is the introduction and function of dry oil-free screw compressor:

Introduction: 
1. Oil-free design: The core feature of dry oil-free screw compressors is that they do not use oil to lubricate the screw. This means that the compressed air or gas will not contain oil vapor or liquid droplets, ensuring that the output gas is clean.

2. Screw element: There is a pair of precision screws inside the compressor, which mesh with each other and rotate to suck in and compress air or gas.

3. High efficiency: Dry screw compressors usually have a high energy efficiency ratio because their design reduces energy loss.

4. Cooling system: Since oil is not used as a cooling medium, dry oil-free compressors require an effective cooling system to control the heat generated during the compression process.

Effect:


1. Provide clean compressed air: For fields such as food processing, pharmaceuticals, electronic manufacturing and breathing air, very pure air is required, and dry oil-free screw compressors can meet this demand.

2. Energy Saving and Emission Reduction: Due to their efficient design, these compressors help reduce energy consumption and operating costs while reducing their impact on the environment.

3. Reduce maintenance costs: No use of oil means no replacement of oil filters, cleaning of oil separators and waste disposal of oil content, thus reducing maintenance costs and downtime.

4. Suitable for various environments: Due to its clean and safe characteristics, dry oil-free screw compressors are suitable for various environments, including demanding medical and research facilities.
