This machine has a one-gallon [4 liter] reservoir to hold fogging
liquid. On the 7807 the fogging nozzle is at the end of the hose/wand
assembly; on other models Except for the 7807, it is mounted in the
power head;
Description of Operation
Fogmaster foggers atomize liquids into small droplets (fog or mist)
by shearing them in a highly turbulent section of the nozzle. A blower in
the power head supplies air to create the turbulence.
The liquid flow rate controls fog characteristics and average droplet
size. A low rate (1-2 ounces [30-60 ml] per minute) produces a dry fog of
small droplets that float extensively and diffuse widely. Larger flow rates
(4-8 ounces [100-250 ml] per minute) produce progressively larger
droplets (wet fog, fine mist).
Liquid flow is regulated by a control valve or, for certain models, a
fixed flow restrictor in the liquid intake line.
Calibration
Adjust the angle of the nozzle for your application and adjust the
liquid control valve to obtain the desired fog droplet size characteristics.
Remove the power head from the tank or drum adapter. Place
power head on a suitable stand, or suspend by its handle.
Fill a graduated cylinder or jar with a measured quantity of your
fogging liquid. For hand held models, position the cylinder or jar so the
liquid level is 6” (15 cm) below the fogger nozzle and insert suction tube.
Operate the fogger for 60 seconds. Remove suction tube, measure
remaining liquid and compute liquid consumed. This is the flow rate per
minute.
At low liquid flow rates, you may have to operate longer than one
minute to get an accurate flow measurement.
