Electric fogger parts

Thermal foggers can be separated into two categories – electric and gas foggers. Gas foggers work by attaching a gas cylinder to the fogger, usually propane gas, and gas from the cylinder is used to heat the burner unit of the fogger. The principle of electric thermal fogger is pretty similar, it also heats up the insecticide into a burner barrel, but instead of using a propane cylinder electric foggers have an electric motor built into the unit that does the heating process and the fogger must be attached to an electricity supply in order to be able to work.

The basic design and look of an electric fogger is pretty similar to a propane fogger, however there are some differences between the two fogger types, so we are going to look at parts from which an electric fogger consists.

Body, motor and handle

The body and handle of the fogger looks pretty similar to gas foggers. The body is pretty basic from the looks and you will find a motor inside the body of the fogger. The motor used in electric thermal foggers is electro-mechanical that produces multiple thousand strokes per minute depending on the power of the motor, also electric foggers come with engines with various voltages. Electric thermal foggers can be used both indoors and outdoors.

In order to make it easier to carry around there is a handle on top of the tool. In the handle there is a built in fogging trigger, which when pressed pumps the insecticide from the insecticide container into the heat barrel where it vaporizes and is sprayed trough the nozzle. The fogging process with an electric fogger is similar to fogging with a propane fogger. The spraying trigger must be pushed in few second intervals to produce a dry fog which works the best for an outdoor application. Some foggers may have a trigger lock button near the handle. This button is used to lock the fogging trigger so you don’t accidentally pump the insecticide into the burner while operating the fogger.

Insecticide container and pump

Insecticide container is attached to the bottom part of the fogger. This container is used to store an insecticide or other type of solution that is used in the fogging process. The jar can be made from either a plastic or metal material. For cheaper foggers a plastic jar is used while more expensive mosquito foggers have a metal jar. Plastic jar needs to be screwed to the bottom of the fogger, while metals jars mostly can be attached to the fogger with special mounts that are located on the sides of the fogger. For mosquito foggers that use an aluminum container, there is a rubber gasket inside the container that helps to firmly attach the container to the fogger. If the gasket has worn out or have been lost, the fogger might not operate correctly. The size of the solution container can differ for different mosquito foggers, but the most common sizes are around 3 liters (~100 oz).

Inside of the jar a solution pump is located that pumps the fogging solution from the jar to the heat barrel when the fogging trigger gets pressed. The pump kit consists of such parts as suction tube, filter, spring, piston and others. It is important to keep the pump clean from dust, so it doesn’t clog and allow fogging solution to freely flow trough the tube.

Flow adjustment valve

Most electric thermal foggers have a flow adjustment valve which regulates the amount of insecticide that gets pumped when the trigger is pressed. Adjustment valve is usually located close to the handle or fogging trigger. By turning the flow adjustment valve you can make the fogger produce a more dry or more wet fog. If valve is completely closed the fogger will not pump any insecticide from the container, and if the valve is fully opened, the fogger is going to pump the maximum amount of insecticide into the heat barrel when fogging trigger is pressed.

Heat barrel assembly

The heat barrel is located in front of the fogger and can be attached or detached from the fogger. Make sure to properly attach the heat barrel to the fogger before using it, there shouldn’t be any gaps between the fogger and the barrel. When you attach the barrel to the fogger you need to push the barrel all the way in to hear a click at the end which confirms that the barrel is properly attached to the fogger.

Between the heater barrel and the fogger there is a small spinner nozzle nut, trough which the insecticide gets pumped from the container jar to the burner barrel. Make sure that the nozzle is not clogged and liquid can easily flow trough the nozzle. The hear barrel is heated to a high temperature with electricity and the insecticide gets pumped from the container, vaporized and sprayed out trough the nozzle in form of a fog.

Electric cord

On the back of the fogger there is an electric cord that needs to be plugged into a proper electricity socket for fogger to work. The electric cord is usually about 1 feet long, so you will need an extension cord in order to use the fogger outdoors. Make sure that you only use an extension cord that is made especially for outdoor usage to avoid any safety issues while using the insect fogger outdoors. The recommended extension cord sizes for outdoor use need to be indicated in operation manual of each mosquito fogger.
