Is this the same as the 40 bar spec page?
That page is the pressure point. This page is the blowing process. Use either; put cavities on both RFQs.
Application
Compressor for PET bottle blowing
Bottle blowing is a high-pressure oil-free process. The blower OEM’s pressure and the cavity count size the compressor, not the word PET.
What belongs on the RFQ
Same sheet, matching plants
A PET line that adds cavities next year will starve a skid sized only for today’s FAD. Put current cavities, bottle litres and whether recovery air is used.
Matching plants are listed Chinese works with PET / HP series. The plant remains the seller; commissioning at the bottling hall is a plant or local partner scope — write it if you need it.
- Bottle volume, cavities, cycle time
- Working and recovery pressure
- Oil-free class
- Cooling water
- Voltage / frequency
- Installation / commissioning if in scope
Matching plants
Match pool — published rows only
The plant remains the seller. Quotes are comparable because the RFQ is the same sheet.

FAQ
Compressor for PET bottle blowing — buyer questions
Compressor for PET bottle blowing: Voltage and frequency matter as much as bar. Typical first reply: 1–2 working days after the plant confirms it can hold the duty.
