Compressed Air Solution for PET Bottling

Why Does the PET Bottling Industry Need 100% Clean Compressed Air?

The PET bottle manufacturing faces specific challenges in maintaining the highest quality standards while ensuring the safety and efficiency of the production process. Compressed air plays a crucial role in a variety of stages, from conveying materials to packaging, and any contamination can lead to serious consequences, including:

• Product Contamination: Compressed air comes into direct contact with bottles, caps, and packaging materials. If the air is contaminated, it can introduce harmful substances into the product, risking consumer health and safety.
• Regulatory Compliance Issues: Glass bottling operations are subject to strict food safety and quality standards. Contaminated air can compromise compliance with key certifications like ISO 22000, potentially resulting in fines and operational delays.
• Production Downtime: Air contamination can damage machinery and components, leading to costly downtime, repair costs, and lost production time.
• Brand Reputation Damage: Contaminated bottles can negatively impact brand reputation, eroding consumer trust and loyalty.

Gairs’ Solution: Water-Injected Oil-Free Compressors

GAIRS is proud to be a leader in providing water-injected oil-free compressors specifically designed for the PET bottling industry. Our OGWBE model is the world’s first two-stage water-lubricated oil-free single screw compressor, launched in 2008, and remains a groundbreaking solution for high-pressure applications.

In 2008, Gairs launched the world’s first two-stage water-lubricated oil-free single screw compressor – the OGWBE. This innovation marked a significant milestone in the compressed air industry, particularly for high-pressure applications in sectors like PET bottling. The OGWBE compressor, capable of achieving exhaust pressures up to 40 bar, was specifically tailored for PET bottling applications, a field that traditionally relied on piston compressors. Our solution eliminated the need for these additional components, improving efficiency and reliability.

This pioneering compressor was developed to handle the high demands of PET bottling plants that require consistent, clean, and reliable compressed air to ensure smooth production. The OGWBE has since become a staple in the PET bottling industry, ensuring top-notch air quality and operational performance.

Applications of Compressed Air in PET Bottling Production

1. Packaging and Bottle Handling

Compressed air is widely used in PET bottle packaging and handling systems. It provides clean, efficient power to move bottles through the production line, ensuring that the packaging process is both precise and free from contamination.

2. Bottle Blowing

Air compressors are used to generate high-pressure air that is essential in the bottle-blowing process, where PET preforms are heated and shaped into bottles. Clean, high-pressure air is crucial to ensuring the uniformity and integrity of each bottle.

3. Capping and Sealing

Compressed air powers systems that cap and seal bottles once they are filled with the desired product. Using clean, oil-free compressed air in these stages ensures that no contamination occurs during the sealing process, which is crucial for food and beverage products.

4. Sterilization and Cleaning

In PET bottling operations, air compressors are used for cleaning and sterilizing bottles, caps, and other equipment. Compressed air is employed to blow away debris and sterilize surfaces before the filling process begins, preventing contamination.

5. Filling Process

In some filling systems, compressed air is used to drive pumps and move liquids into the bottles. Clean, oil-free air ensures that the liquid remains uncontaminated during the filling process.
