The compressor is the lifeblood of any workshop, and there's no doubt about that. Today we'll move on to the next step: choosing the right capacity and power. These are the two numbers that separate a compressor that's a pleasure to use from one that always falls short.
With Oil or Without Oil?
Without oil: zero maintenance and clean air, ideal for home use and painting.
With oil: longer lifespan in intensive use.
Tank: The Right Liters
- 6–24 L - inflating tires, small jobs with a blow gun;

- 50 L - the balance for DIY: spot painting, lightweight pneumatic tools;

- 100–200 L or more - workshop and professional use: impact wrenches and continuous painting.

The Number Almost Everyone Ignores: Air Flow
More important than power is the air flow rate (L/min). Add up the consumption of the tools you will connect and ensure that the compressor delivers with a margin above this value. This is what prevents constant stops to refill the tank!
Frequently Asked Questions
Which compressor for painting?
Prefer a 50 L or larger tank and ample air flow. Painting requires continuous and stable air.
What pressure do I need?
Most tools work at 6 - 8 bar. Any good compressor will do, the flow rate is what matters.
Is single-phase enough?
Up to medium tanks, yes. For workshops with high consumption, consider three-phase!
