The Portable 5 Gallon 305 4-Way Fogger is a chemical atomizer that uses compressed air (29.5 CFM @ 80 PSI) and venturi action to draw ready-to-use chemical solution from a user-supplied chemical pail on the all stainless steel cart. It will atomize the solution and project it as light, "damp" fog particles in 4 directions up to 25 feet. This unit features a telescoping mast and can also be used as a 2-Way fogger.
