Liquid aerosol generators are intended to produce shaped aerosol structures which is achievable by spraying various liquids and their mixtures in the air.

With the aid of those devices, one can produce such shaped aerosols that can be successfully applied to address both scientific and technological problems of various kinds across a broad spectrum of their applications.

So, for example, these devices can be used to create such aerosol structures that may be designed to find their way to applied physics research on radio wave and laser radiation decay and diffusion.

Custom-made aerosol structures can be employed to protect buildings and personnel inside those buildings from blast waves, an impact of electromagnetic radiation across a wide range of wavelengths, etc.

Besides, these devices can be very effective in resolving such environmental challenges, as, for instance, neutralization of the formation of hazardous substances in upper and low atmosphere, elimination of the deleterious emissions, etc. Our proprietary aerosol generators can also be widely used in agriculture and various industries.

The basic unit of the aerosol generators is a spray nozzle the design and characteristics of which pre-determine such principal parameters of shaped aerosols as the dimensions of their droplets, value and shape of aerosol formation, etc.

Certain types of our proprietary nozzles, inherent to aerosol generators of diverse applications, as well as their main characteristics, are given in Figures 1 through 4.
