The power of the engine installed in the compressor. It is not the main parameter in evaluating the efficiency of the device — here the performance and nominal pressure play a decisive role (see above), and the engine is selected in such a way that its power is sufficient to ensure the claimed characteristics. However, this indicator still has practical significance: in compressors with an electric motor (and there are now most of them; see “Engine type”), the engine power determines the total energy consumption of the device, as well as the requirements for the network where it is planned to connect it (for more details, see “Voltage networks"). In addition, the power of the engine (regardless of its type) must be known in order to calculate the optimal performance value using some special formulas.

For internal combustion engines, power is traditionally expressed in horsepower (hp); you can convert it to watts in this way: 1 hp. = 735 W.

The sound pressure level in decibels at a certain distance between the noise source and the ear of the compressor equipment operator. Since people do not work in the immediate vicinity of the compressor, the parameter will be useful for estimating the noise level at a distance. It is most often measured at a distance of 7 m from a working installation, less often at a distance of 1 m.
