ABSTRACT:
A diffusion fogger is packed on a road case. Fans draw air through a baffle chamber and through fan openings into a fan chamber, an air compressor above the fan chamber provides compressed air to a fog head assembly. The fog head assembly releases an oil mist fog into a fog duct. Air from the fan chamber is blown through the duct and out through a front opening, entraining and delivering the fog. Air from the fan chamber is circulated over a path that serves to cool the compressor, compressed air, and exhausts from the outlet ducts. The fog head is a removable vertical assembly of an oil sump chamber and a nozzle array chamber. The nozzles, with inlets to an air manifold draw up filtered oil from an oil manifold and spray a fine mist of oil and decompressed air into the nozzle chamber. The mist continues through the next above baffle box filled with marbles, removing large oil droplets. Oil collected by the marbles drains through the nozzle chamber into the sump, and the mist continues upward and horizontally through the top filter chamber, which has a foam filter. The mist is exhausted into the mist duct, where it is entrained in the air delivered by the fans which carries the fog to the desired location. The fog head and mist duct are located in a vertically hinged door on the road case.
