Compressed air is an inexhaustible power energy source, which is generally used in the automation production process of food and beverages. For some special processes in the food and beverage industry, such as PET blowing bottles, it is necessary to use compressed air to contact the product directly, and it is required to be 100% pure oil -free air.

If the compressed air is treated without the purification system, different applications will cause defects, such as :

Insufficient air pressure will result in orange peel-like patterns appearing on the surface of the blow molding product, the outline or graphic will not be clear, and the volume of the blow molding product will also reduce.

Impurities in the compressed air will cause anesthesia on the surface of the blow-plastic product

Compressed air pressure is too high will cause the product molding type embryo to blow.

Water and oil vapours in the air cause the product to be polluted and wasted.

Therefore, it is particularly important to choose a suitable, reliable, and quality -guaranteed compressed air. In general, air treatment includes the use of an air dryer or adsorption dryer that removes condensates from the compressed air in order to make it dry. High-efficiency air filters are used to remove all types of pollutants from the air, then the pure air transported in the pipeline and in direct contact with plastic bottles.
