Many bottles are now made of polyethylene terephthalate (PET). Compressors are used to blow plastic into the shape of a bottle. Since there are many different PET bottles are used to make a wide variety of products, there are different results that people in the PET industry are seeing. This diversity in results means that there must be various types of compressors for those in the PET bottle industry.

Three-stage lubrication air-cooled piston

These are typically smaller systems that can deliver up to 580 psi. It is a good unit for companies that wants to make good use of their space. Under normal conditions, this type of compressor can operate for 10 to 12 years.

High pressure Four-stage Centrifugal

It is a larger oil-free system. It is also an efficient space option, but it requires more energy. This type of compressor can be expensive to repair. Under normal circumstances it can operate for 10 to 15 years.

Single stage boosters

The single stage can be available in lubricated or non-lubricated, as well as without oil and water cooled. A single booster is not as space efficient as other compressors. The life of such a compressor varies depending on cubic feet per minute, but it can be anywhere from 10 to 50 years.

Three-stage water-cooled piston

This is a system without lubricants and water coolers that can be configured with efficient space. It’s good for PET plants. This type of compressor can be used for 20 to 30 years.

Since there are many different compressors types and much more compressor manufacturers, it can be difficult to find the right replacement parts when you need them. Fortunately there are manufacturers who have the know-how to manufacture everything from the crankshafts to piston rods that tie plates specially designed for use in PET air compressor. If you are in the PET industry, be sure to purchase replacement parts to help your compressor keep working well.
