How to choose a compressor

The compressor is an extremely versatile tool, useful both in the hobby and professional fields. It can be used to inflate tires, paint, clean with compressed air or power pneumatic tools. To choose the right compressor it is essential to carefully evaluate the usage needs and the technical characteristics of the device.

What is a Compressor Used For?

The compressor draws air from the outside, compresses it in a tank and releases it under pressure to power tools or perform specific operations. It is used for:

• Inflate tires, swimming pools or inflatable games;

• Blow away dust and debris from surfaces and machinery;

• Spray painting, sanding, nailing or tacking;

• Use compressed air tools in a professional context.

Features to Evaluate

Air Flow and Pressure

The air flow rate determines how much air the compressor can supply in a minute, and is expressed in litres/minute (l/min):

• For occasional use, 100–200 l/min is sufficient;

• For continuous or professional use it is better to aim for models with 300 l/min or more.

Pressure is measured in bars (typically between 8 and 10 bars) and must be sufficient to power the tools you intend to use.

Tank Capacity

The tank stores compressed air to ensure stable delivery:

• 6–24 litres for short or domestic jobs;

• 50–100 litres for intensive use or with pneumatic tools;

• Larger tanks reduce the frequency of engine activation.

Compressor Type

Based on their structure and functioning, they are distinguished as follows:

• Coaxial (direct) compressors: compact and lightweight, suitable for hobby use;

• Belt driven compressors: quieter and more durable, perfect for professional use;

• Oil-free compressors: ideal for working in environments where clean air is required (painting, food).

Food and Mobility

Check the most suitable power supply type:

• Single-phase compressors (230V): for domestic and artisanal use;

• Three-phase compressors (400V): for more intensive professional uses.

Also, consider whether it has wheels and a handle for easy transportation.

Noise Level

When working in closed or residential environments it is important to consider decibels (dB):

• Silenced models produce less than 70 dB;

• Standard compressors range between 80 and 95 dB.

Accessories and Compatibility

Check the compressor equipment:

• Pressure reducers, pressure gauges, safety valve;

• Quick couplings for pneumatic tools;

• Compatibility with airbrushes, inflation guns, screwdrivers and nailers.
