The Actisol unit basically makes an aerosol for you by combining a low volume of insecticide with a high volume of air, ideal for crack and crevice treatments and deep harborage/void treatments. Actisol allows you to apply particles mostly in a range of 2.4-15 microns without the addition of any propellants. Particle size will vary with pressure.
