US Patent 7552914 High pressure humidifier

A high pressure water injection humidifier includes a filtration system (11) to filter an incoming water supply and provide filtered water (6) to a low volume high pressure pump (12) driven by a constant speed motor (13), which in turn provides pressurized water (7) to a plurality of exit nozzles (17), each exit nozzle having a precision orifice that atomizes the pressurized water into a mist, where the volume rate of the mist is dependent only on the motor speed and the diameter of the precision orifice.
