The results of the research are given to show the possibility of reducing the agglomeration of aerosol nanoparticles using the needle-plate corona charger. It has been found that the charger fulfills the functions of an electrofilter-separator, precipitating large particles of agglomerates at a size more than 250 nm, leaving smaller non-agglomerated particles in the flow. Using the developed charger allows us to significantly reduce the agglomeration of particles at sufficiently low aerosol flow rates. As a result of changing the parameters of the charger (corona discharge current from 35 to 215 $\mu$A, aerosol flow through the charger from 33 to 250 l/min and the corona polarity), the mean particle size decreases more than in 1.5-fold.
Keywords: the needle-plate charger, agglomeration, aerosol, the multi-spark discharge generator.
