Swingfog fogging machines
run with regular grade gasoline (petrol) in accordance with the Swingfire principle. A fuel/air mixture is ignited in the combustion chamber and the deflagrations oscillate a column of gas in the resonator pipe between 80 and 110 times per second (depending on the type of machine). At the end of the resonator, the fogging mixture is 4-5 msec injected into the air stream emerging at high velocity, and is dispersed into fine aerosol droplets, which are distributed into an extensive, dense fog. Fuel and fogging mixture are conveyed by a small positive pressure in the tanks*. The system has, with the exception of diaphragms, no moving parts and, therefore, practically no wear. |
