Spray Machine is a electric aerosol applicator and portable disinfection equipment used for airway disinfection.

At the end of the removal of dust and washing cycle, it is usually necessary to proceed (away from human presence) to the diffusion by airway of a disinfection or deodarization product.

It consists in diffusing in a closed site, a steady fog of particles readily controllable from 5 to 40 microns in size which will settle on every surface area and wall needed to be treated.
