Oil-free or oil-injected for PET?
Blowing air is oil-free. Do not send an oil-injected 40 bar booster unless the OEM allows it with treatment you will actually install.
Parameter duty
40 bar PET compressor
PET blowing at 40 bar(g) is a high-pressure oil-free duty. Cavities, bottle volume and recovery pressure size the skid — not the word “PET compressor”.
What belongs on the RFQ
Same sheet, matching plants
A 40 bar PET package is sized from the blower: bottle litres, cavities, cycle time and how much recovery air returns. Sending “40 bar oil-free, China” gets a brochure, not a comparable quote.
Write oil-free at the stated ISO 8573-1 class, 40 bar(g), recovery pressure, cooling water temperature, 50/60 Hz and whether the low-pressure stage is screw plus booster or a dedicated HP machine. FOB Shekou is common for Guangdong plants; FOB Shanghai for East China.
Listed plants with PET / HP series appear below as published. We do not fill empty FAD cells with a guessed 3.2 m³/min.
- Bottle volume and cavity count
- 40 bar(g) and recovery pressure
- Oil-free class and booster staging
- Cooling water and voltage
- Quantity of skids
- FOB Shekou / Shanghai or CIF named port

FAQ
40 bar PET compressor — buyer questions
Who is the seller?
The plant that packages the skid. This desk routes the English duty sheet.
40 bar PET compressor: Voltage and frequency matter as much as bar. Typical first reply: 1–2 working days after the plant confirms it can hold the duty.
