Misting SA ULV Trailer/Vehicle Mounted Fogging Machine is designed to disperse concentrated formulations at flow rates in the range of (15-590 ml/min) with droplet sizes less than 20 microns VMD (volume-median-diameter). When equipped with the Pumping System, flow rates of up to (3560 ml/min.) are possible.
This machine is to be vehicle or trailer mounted.
WORKING PRINCIPLES
An 11 horsepower, four-cycle gasoline engine is used to drive a positive displacement backward curved centrifugal operating fan to generate (3.5 cu.m./min) of air. The air entering the fan is first filtered through a large steel filtering grid. The speed of the engine (approximately 3600 rpm maximum) moves this large air mass through the boom assembly. Attached to the boom assembly are nozzles. The nozzle has six stationary fins that create a swirling effect of the air mass as it leaves the nozzle. In the centre of this swirling air mass is a liquid supply spray tube. The spray tube directs the formulation into the air mass where it is sheared into billions of tiny droplets and dispersed into the atmosphere. The formulation is delivered into the spray tube by means of a 24 volt DC pump that draws the formulation from the tank, through a filter, then pumps it into the nozzle spray tube.
