Claim:
A dry disinfectant spray apparatus converting ambient air to spreading gas disinfectant, said free radicals comprising: a linear array of three faced-downward magnetized torch modules held together in a box housing; a rectangular cap covering the array of three torch modules with a slit on the top wall for exiting the plasma effluent of the torches; the cap holding three pairs of rectangular permanent magnets on its two side walls to spread the plasma effluent of the torches along the slit of the cap; a power supply having three high voltage (HV) output lines connected to the central electrodes of the three torch modules to energize the torches and a common ground line connected to the outer electrodes of the torches; an air pump supplying airflow into the box housing of the torch modules, the said box housing functioning to distribute the input airflow evenly to the gas plenum chambers of the torch modules; the said airflow, delivered from a gas plenum chamber to the electric discharge gap of a torch through the openings on the frame of the torch, functioning to push gas disinfectant, said produced by the electric discharges, out of the discharge regions for applications.
