Can 8 bar plus a booster replace 13 bar screw?
Sometimes. Put the OEM letter on the RFQ so plants quote the architecture they can warrant.
Application
Compressor for laser cutting
Laser tables do not run on 8 bar workshop air. Pressure, dryness and oil content sit in the OEM warranty. Copy those numbers onto the RFQ.
What belongs on the RFQ
Numbers a plant can quote
One 6 kW fibre table is not the same FAD as a cell of four. Count tables, pierce vs cut pressure, and whether nitrogen is separate. Then the screw (often 13 bar class) and dryer can be sized.
Matching is listed screw plants. Oil-free is only required if the OEM says so — do not upgrade the quote because it sounds cleaner.
- Table OEM working pressure
- Number of tables and shift pattern
- Dew point / dryer
- Oil-injected with filtration or oil-free
- Voltage
- Incoterm

FAQ
Before you send the sheet
Compressor for laser cutting: Voltage and frequency matter as much as bar. Typical first reply: 1–2 working days after the plant confirms it can hold the duty.
