Category:Supercharged Sirens

A supercharged siren is a mechanical siren that makes use of a Roots blower, centrifugal fan, or other form of air compressor to force high volume air into the siren's rotor. This causes significantly more air to be chopped by the rotor during operation, significantly boosting the decibel output and range of the siren. However, the downside of these sirens is that without the supercharger, the siren is much quieter. These sirens require more maintenance than standard electromechanical sirens due to the additional moving parts.

These are not to be confused with pneumatic sirens, which require an external source of air to operate, unlike a supercharged siren.
