Principles Of Operation; Main Components - Vector Fog VECTORFOG H400 Instruction Manual

VectorFog™ Thermal Foggers are powered using the pulse jet principle. Pulse jet engines don't have any moving
parts; instead they have a funnel shaped combustion chamber similar to a rocket engine which opens into a long
resonator or exhaust pipe. VectorFog thermal foggers have an auto start and operate through compressed air via a
compressor. When the auto start button is pressed, the compressed air pressurizes the fuel tank, causing fuel to flow
to the injector and then into the carburettor. Air/fuel mixture is then ignited by a spark plug in the carburettor. The
spark is created by an ignition coil which is powered by a rechargeable battery. The ignition coil, battery and
compressor are all housed inside of the main body of the machine. Operating at its optimum performance,
combustion and injection is repeated with a frequency of around 200-250 cycles per second. Once the machine
starts, the chemical tank also becomes pressurized by means of a non-return valve. A close valve and supply valve
are then opened to allow the flow of the chemical/oil solution in to the resonator. At this stage the solution is
heated up to around 1,400º C and dispersed into millions of tiny droplets (around 10-30 microns in size) creating a
dense and visible smoke.
