A fluid sprayer includes a housing defining a reservoir attachment portion, a pump supported within the housing, a nozzle assembly supported by the housing and located in fluid communication with the pump, and an electrostatic charging circuit configured to impart an electrostatic charge in a fluid pumped out of the nozzle assembly by the pump. The fluid sprayer also includes a first reservoir including a first latch configured to releasably secure the first reservoir to the reservoir attachment portion to fluidly couple the first reservoir to the pump. The fluid sprayer further includes a second reservoir including a tank, an adapter, and a hose fluidly connecting the tank to the adapter, the adapter including a second latch configured to releasably secure the adapter to the reservoir attachment portion to fluidly couple the tank to the pump.

An applicator is disclosed for applying a treatment solution to a treatment site of a patient. The applicator can include an applicator housing comprising a treatment solution reservoir. A cartridge can be removably disposed in the housing. The cartridge when arranged in the housing can be in fluid communication with the treatment solution reservoir. The cartridge can include an electrostatic module for electrostatically charging the treatment solution in the treatment solution reservoir; and a nozzle for applying the treatment solution.

An electrostatic sprayer operable at high flow rates and low pressures particularly suitable for spray drying. The sprayer includes an elongated body having a downstream spray nozzle assembly through which electrically charged liquid is directed via a central feed tube within the nozzle body and atomizing air is supplied via an annular passage about the liquid feed tube. In one embodiment, the nozzle assembly is an external mix cluster head spray nozzle assembly having a plurality of circumferentially spaced metallic spray tips. In another embodiment, the spray nozzle is an internal mix nozzle assembly having a spray tip with an internal mixing chamber for atomizing liquid prior to discharge.
