Particle Size Matters
While both foggers and electrostatic sprayers produce fine liquid particles, which are both good for covering large open areas. It is noteworthy that the mist is not “the finer the better”.
Foggers usually produce particles that could be as small as 10 microns in diameter, which could be evaporated very easily, sometimes too quickly. The Vycel 4 will produce 40 microns particles, which is optimal for disinfectant and coating (such as Quaternary Ammonium compounds) to have dwell time on the surface and be effective.
Advantage of Electrostatic Spraying
Electrostatic sprayer will charge the liquid with positive ions, so that the particles will carry a positive charge, and be attracted to the naturally negatively charged target surface. Therefore, the particles will cover the surface evenly and thoroughly, also spread onto confined or conceal surface easily. It also helps with the efficiency so that you can use up to 75% less solution.
The electromagnetic bond is also great for applying disinfectant or coating, as it will hold the particles onto the surface firmly. For self-disinfecting coating, you need not to worry about the coating coming off when wiping down.
