Scroll vs screw for a small CNC shop?
Scroll if oil-free lab-like air at low FAD; screw for a cell. Put FAD on the sheet rather than the architecture fashion.
Application
Compressor for CNC machines
Machine tools need dry, stable 7–8 bar air. Size from the cell, not from a round kW number a vendor likes to sell.
What belongs on the RFQ
Numbers a plant can quote
A shop with six VMCs and a laser in the next bay is two duties. Put CNC air separate from laser assist air. For the cell, count machines, tool-change blow-off and whether a receiver already exists.
Listed screw plants quote this as general industry. VSD helps if the night shift is one machine; it is optional, not a religion.
- Machine count and blow-off use
- 7–8 bar(g)
- Dryer requirement
- kW limit or FAD
- Voltage
- Incoterm

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