A device to increase the magnitude of flow while releasing small amounts of compressed air at high velocity through cylindrical nozzle. This jet of air released through the mouth of the nozzle creates a vacuum behind, thus pulling ambient / surrounding air from the rear to push ambient air in front. Thus, the total output air pushed to the front is induced air plus compressed air and it gets the flow amplified by up to 50 times of the compressed air released from the nozzle.
(In the USA, this term is used to also describe pneumatically operated piston-type booster compressor).
