Описание к видео How its work - Compressed Air Driven - Air Amplifier

These are simple vacuum pumps based on a venturi airflow design that can be used for vacuum pressures up to 28" of mercury vacuum. The pumps require a source of compressed air in order to function but require no electricity. Once the source is hooked up the pumps can be set up to reach vacuum pressures from atmospheric pressure to 28" and all pressures in between can be regulated.


Principle of Operation
When compressed air is forced through a conical nozzle, its velocity increases.  This principle was discovered by a 18th century physicist, G. B. Venturi and can be applied to generate vacuum economically without a single moving part.
