Mini Thermal Mosquito Fogger Machine Gas Powered

This Krisbow 2000G fogging machine is practically used for mosquito fogging, and it is suitable to be used at narrow spaces.

This machine has 2 tanks.  The large orange tank is a container for chemical fluids that kill mosquitoes and other insects.

A small semi-transparent white tank is a water bottle for rinsing the heating pipe.  Insect-killing chemical can leave sediment in a spiral-shaped heating pipe.  If there is a lot of sediment then the pipe becomes clogged. And it is difficult to clean it because of the spiral shape of the pipe.

The photo above is the right side view of this Krisbow fogger.  There was a small semi-transparent bottle filled with green dishwashing soap water.  This soapy water will later be used to rinse the pipe as soon as the fogger has been used, so as to prevent deposits from chemicals clogging the pipe.

Orange tank is used store insecticidal chemicals (pesticides, insecticides).  Maximum capacity of 2 liters or 2000 grams.

As shown in the photo, the gas cylinder or gas can is still not installed yet.  The gas cylinder must be removed if the fogger is not used,  to prevent gas leakage.

On the right side of the fogger, there is a red button to provide the electric spark to ignite the gas. If this button is pressed, an electric spark will come out under the gas pipe in the fogger's muzzle, so that the gas will be ignited.

Another red knob is at the back of fogger, above the gas cylinder.  If this red knob is turned to the left, it will open the gas flow.  The more it rotates to the left, the greater the gas fire will be.

The photo above shows the left side of the fogger. The gas cylinder is mounted already at the back of the fogger. The fogger's snout is smoldering because of the gas fire. Fogger is ready to use.

Note that the gray tap is set in a vertical position, so that insecticide can flow from inside the orange tank up towards the fogger's snout

The insecticide pump is activated by squeezing the blue handle on the top of fogger. So that the insecticide will rise out of the orange tank, then it evaporates in a spiral heating pipe and spray as smoke.

In the photo above, the rinse water bottle is turned over and slightly kneaded so that the soapy water comes out to rinse the heating pipe.  Actually this can be done with a rinse pump at the back of fogger. But sometimes the pump is not effective. Note the gray faucet on the left side of the fogger, the faucet is set in a horizontal position so that soapy water flows from the back of fogger into the heating pipe in the fogger's muzzle.

Fogger can also be rinsed with tap water. Photo above shows the fogger is rinsed with tap water. The small bottle is removed, then the bottle hose is connected to the water tap via the orange hose. Seen at the left side of fogger, the gray tap is set in the horizontal position. If the water tap is opened, tap water will flow into the fogger, through a small rinse hose, heating pipe, and out of the fogger's muzzle.

Flushing also needs to be done on the vertical pipe in the insecticide tank. It can be done by filling clean water into orange tank. Or by preparing clean water in a bucket, and the orange tank is removed.

The photo above shows the fogger with the insecticide tank that has been removed. Note the vertical pipe where there is an insecticide pump, that pipe is dipped in a bucket of water. The insecticide pump is then activated so that the water from the bucket is pumped up. Then water exits through the heating pipe in the fogger's muzzle. Note the gray tap position is set in the vertical position.

Flushing must be done immediately after the fogger has finished smoking, do not wait a few minutes. Make sure the rinse water that comes out of the fogger's snout is clear, indicating there is no insecticide left. This is to prevent deposits from chemicals clogging the fogger pipe.

From experience, usually maximum fogger working time is about 1 hour. Then immediately it is rinsed to ensure no sediment in the heating pipe. Furthermore fogger can be used for another 1 hour. Insecticide consumption is around 1 liter per hour.
