For PET production, oil-free compressed air is a vital source of power 

PET is a globally recognized, safe, recyclable packaging material. Compared with aluminum jar and glass bottle, PET bottle is still a very economic and environmentally friendly packaging choice.

Dry and clean compressed air is needed in PET production lines, raw materials, and molding processing lines. However, compressed air systems always pose a risk of pollution. Dust, humid dust, oil suspension, water droplets, particles and oil steam will threaten downstream equipment and terminal products. Therefore, compressed air quality directly affects PET quality and production efficiency. When the compressed air is blown into the blank into a PET bottle or PET tank, only the Class 0 zero-level recognized oil -free compressed air can ensure that your product is free of pollution.

If the compressed air purification system you choose fails to meet the standards for oil-free compressed air, it will cause defects in different applications of the product, such as:

- Compressed air pressure will cause orange peel-like patterns to appear on the surface of the blow-blowing product. The outline or graphic is unclear. Insufficient air pressure can also cause blow molding products to fail to meet standards.

- Compressed air has impurities caused by anesthesia.

- Compressed air pressure is too high, causing product molding embryo blowout.

- Compressed water and oil pollutants in the air cause the product to be dirty.

This has caused users to become more careful when purchasing a product. This may be one of the reasons they choose YUKA 30 bar or 50 bar high efficiency air filters for PET Blowing.

Application of compressed air

Air cleaning

Oil-free compressed air cleans the bottle and packaging before filling. If the air is contaminated, in addition to being harmful to health, it will also change the taste and smell.

Mid-pressure diversion device

The method of improving efficiency consists of using the middle pressure generated when PET blows, and using this pressure in other processes for instrument operation.

PET blowing bottle

High-pressure compression air blows the bottle into a blowing mold. CLASS 0 Zero-level oil-free air ensures that the bottle is not polluted by oil.

Packing/sticker label

In the process of packaging, labeling, compressed air is used to control valves and actuators in automated pipelines. Oil-free air can prevent automated components from being stuck and ensure the safety of terminal products.
