Can an 8 bar package be set to 10 bar?
Sometimes a two-stage or a different airend. Do not assume a valve change. Ask the plant if the airend and motor are rated for 10 bar continuous.
Parameter duty
110 kW 10 bar rotary screw compressor
10 bar(g) is not 8 bar with a different sticker. FAD falls as pressure rises. Write 110 kW and 10 bar together, then the flow you need at that point.
What belongs on the RFQ
Numbers a plant can quote
A 110 kW screw asked to hold 10 bar(g) is a different machine than the same frame at 8 bar. Plants that only publish 7–8 bar nameplates cannot answer this RFQ honestly without restaging or derating.
Put the duty point on the sheet: 110 kW, 10 bar(g), FAD at 10 bar, ambient, altitude, cooling water if used, and whether you need a VSD band or a fixed-speed point. 50 Hz 380 V and 60 Hz 460 V are not interchangeable without a motor change.
Listed Chinese plants with oil-injected screw series are the matching pool. We issue the same English duty so quotes are comparable. We do not invent a 110 kW / 10 bar SKU where the factory only lists a series.
- 10 bar(g) working pressure as the duty point
- FAD at 10 bar(g), not at 7 bar
- 110 kW or the site limit
- VSD range or fixed speed
- Voltage / frequency and cooling
- Incoterm and destination

The plant remains the seller. Quotes are comparable because the RFQ is the same sheet.

FAQ
Before you send the sheet
Why does FAD drop at 10 bar?
The same shaft power delivers less free air as discharge pressure rises. Quote FAD at the working pressure only.
Who confirms lead time?
The plant. This desk does not hold stock and does not promise a factory slot.
110 kW 10 bar rotary screw 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.
