A technical device or machine used to compress gases, usually air, and increase their pressure. Compressors are used in many areas, such as in refrigerators, air-conditioning systems, or for inflating tires.
example
Mit dem Kompressor pumpte er die Fahrradreifen schnell auf.
He quickly inflated the bicycle tires with the compressor.
Usage tips
Word family
'Kompressor' (compressor) belongs to the word family of 'komprimieren' (to compress). The verb means 'to press together.' So a compressor is literally a 'presser-together' for gases or audio signals.

Technical context clue
When the context is technical, you can recognize this meaning from words like 'Luft' (air), 'Druck' (pressure), 'Reifen' (tires), 'Werkzeug' (tool), or 'Baustelle' (construction site). In this context, it always means the machine for compressing gases.
EXAMPLE

Audio-engineering context clue
In music and audio production, you can recognize this meaning from words like 'Audio' (audio), 'Gesang' (vocals), 'Stimme' (voice), 'Signal' (signal), 'Spur' (track), or 'Studio' (studio). Here it means the effects device.

Kompressor vs Turbo
turbo
'der Turbo' and 'der Kompressor' both have to do with technology, air pressure, and more power. A 'Turbo' is short for 'Turbolader' (turbocharger) and is part of an engine; it helps increase engine power. A 'Kompressor' is more general: it compresses air or other gases and is used in many devices, for example when inflating tires or in air-conditioning systems. Learners may confuse the words because both can compress air and increase power. As a practical rule: with cars, people often talk about the 'Turbo'; with a device for building up pressure, they are more likely to talk about the 'Kompressor'.
