Why Use Oil-free Air Compressor for PET Bottle Blowing Industry

Oil-free air compressors are currently widely used in industries with high requirements for compressed air, such as medicine, precision electronics, and chips. In the glass blowing industry, compressed air also plays a vital role. Next, let’s learn about the applications of oil-free air compressors in the glass production industry? Why should the glass production industry choose oil-free air compressors?


The importance of oil-free air compressors to glass production

First, let’s understand the process of glass blowing. The molding of glass bottles mainly relies on high temperature and pressure to blow-mold preheated glass balls or tubes into the required shape. During this process, if the compressed air contains oil or impurities, they will adhere to the glass surface, causing defects, uneven color and other problems in the product. These defects not only affect the appearance of the product, but may also affect the sealing and durability of the product.



To solve this problem, the glass blowing industry needs clean compressed air. The biggest feature of an oil-free air compressor is that it can provide 100% oil-free pure compressed air. Oil-free water-lubricated air compressors use water for lubrication during the compression process. The compressed air does not come into contact with lubricating oil, ensuring the purity of the output air.


Specific applications of compressed air in glass factories

1, The air compressor provides combustion-supporting air for the combustion of glass liquid in the melting kiln of the production line.

2, Air compressors are used in media transportation processes such as coke powder pipeline transportation and injection.

3, Air compressors are used to provide compressed air to pneumatic equipment in various workshops to control equipment or instrument actuators.

4, When the bag or air filter cartridge of the dust collector needs to be backflushed and cleaned, the compressed air provided by the air compressor also needs to be used.


The benefits of choosing an oil-free air compressor

Additionally, oil-free air compressors offer several other advantages that make them ideal for the glass blowing industry.

1, High stability: The oil-free air compressor adopts a fully enclosed design, which avoids the impact of the external environment on the compressed air and ensures the stability of the output air. This helps to improve the molding quality of glass bottles and reduce the scrap rate during the production process.

2, Easy maintenance: Due to the simple internal structure of the oil-free air compressor, maintenance work is relatively simple. Regular maintenance work such as replacing filters can effectively extend the service life of the equipment and reduce operating costs.

3, Energy saving and environmental protection: Oil-free air compressor adopts advanced energy-saving technology, which can effectively reduce energy consumption. At the same time, because the exhaust gas it emits does not contain oil, it has a small impact on the environment and is in line with the green development concept of modern industry.

4, High reliability: Oil-free air compressors use high-quality materials and components and have high reliability. This helps reduce downtime during production and improves productivity.
