ABSTRACT:
A compact special effects fogger has a small case with a handle on top for ease in transportation. A compressor box is positioned in the case against the base, and against one side and one end of the case. A fogger head box extends across the case on top of the compressor box. The two boxes form within the case a fan chamber at one end, a compressor cooling duct along one side, and an air entrainment duct along the top. A motor drives a compressor within the compressor box. A shaft from the motor extends into the fan chamber. A squirrel cage fan driven by the shaft draws air in through a round opening in the first end of the case and increases pressure in the fan chamber, causing air to flow through the ducts. The fogger head box has an oil sump and an oil intake is mounted in the sump. Oil tubes lead to a nozzle assembly within the fogger head. Compressed air flows through an air cooler in the compressor box and through a water trap in the fan chamber and into the nozzle assembly. The nozzle assembly releases an air-oil mist which flows through openings in an end of a U-shaped marble chamber to remove large oil droplets from the mist. The air and oil mist flows outward through a curved outlet, and then flows upward through an opening in the top of the fogger head box. Air flowing from the fan chamber through the air entrainment duct mixes with an entrains the mist and carries it outward through a full rectangular opening at the top of the second end of the case.
