Myth: PET air compressor systems just need to be “oil-free” to meet manufacturing requirements.

Learn from us: With more than 300 successful PET bottle blowing air compressor installations worldwide and over 25 years of
continuous design, fabrication, installation, refurbishment and maintenance of these systems, you have found a reliable and authoritative source for your next PET stretch

blow molding air compressor system installation. Featuring the highest quality equipment, including Kaeser, Blackmer, FS-Elliott, Kobelco, Ingersoll-Rand, Ateliers Francois and others, Hope Air Systems is uniquely qualified to help you with your PET package requirements.

Hope Air Systems responds: Hope Air Systems has extensive experience in designing PET package systems to meet a wide range of requirements. We have experience with every type of installation including:

• Screw/Booster
• Reciprocating 3-stage
• Centrifugal
• Oil-Free Screw/Booster

New Capabilities: Hope Air Systems continues to expand its capabilities and brings new offerings from 1,000 L/M to 40,000 L/M at 40Kg. We have expanded to include lower cost entry-level primary booster systems, three-stage oil-free reciprocating high pressure compressor chiller systems, blower systems and the support equipment necessary for the typical PET mechanical room in any facility in the world.

Engineering Staff: From its in-house engineering department to its 60,000 square foot fabrication facility in Massachusetts, Hope Air Systems can take your PET air compressor package requirement from concept to start-up. We can provide a complete turnkey design and fabrication of your PET blow molding system.

System Design: When Hope Air Systems receives an inquiry for a custom PET bottle blowing application, we go beyond using just the manufacturer’s specifications for a compressor. We analyze complete plant air usage for both current and future plans. We look to reduce operating costs so new PET bottle blowing systems pay for themselves over time.

PET bottle invented in 1970’s
A patented process created by researchers at Dupont in the 1970’s was the beginning of the “oriented PET bottle.” Dupont’s process ultimately became the preferred method for making soda bottles. We have all become familiar with soft drink bottles of all sizes made from “plastic.”

The so-called “biaxial orientation” process used in modern soft drink bottles makes the plastic clearer, stronger, lighter and less permeable to moisture and gases. In this way, it has become an acceptable substitute for glass. Earlier plastic bottles were rejected by the US government for use in consumer products as not safe.

The first commercially available PET bottle was a 64 oz Pepsi-Cola bottle in 1977. Since then, stretch-blown PET bottles have grown to an 18-billion-unit market in the US.
