Thermal Fogger parts in general
There are different types of foggers like electric or thermal fogger and each of these types have different parts suited for either cold or thermal fogging. Today we’ll look at propane foggers which are a subcategory of thermal foggers and find out from what parts they consist. It is vital to know each part of your fogging device as well as the basic operational principles of an insect fogger. This knowledge will be useful for maintenance and repairs of your fogging device as well as give you understanding of safety cautions you need to consider when operating an insect fogger.
The basics of each fogger, whether used for insect fogging, plant fogging or other activities is the same. Generally, a fogger is a device that turns some sort of liquid into fog, which consists of very small particles of this liquid that might be combined with water. To perform such process a fogger must consist of few parts.
First of all the body of a fogger must be made convenient to carry around so most foggers have specially made handle on top of the device. The body of a fogger is usually made from a tough plastic like nylon. On body you will find most important buttons and triggers that are used to operate the fogger. These triggers are placed in such spots that they are easy to reach in the fogging process.
Probably the most important part of a fogger is spray nozzle that is located in front of the body of a fogger. This spray nozzle consists of few key parts such as coil, protection basket, spray tip and other. The spray nozzle gets heated by electricity or some sort of gas like propane so insecticide or other type of liquid running trough the nozzle gets heated and gets sprayed out in very small particles that all together look like a cloud of fog.
Insecticide is stored in a special container under the body of a fogger. These containers are usually made from either a plastic on most foggers or metal on high end and commercial foggers. In the container there is a small pump that pumps the insecticide into the burner, which heats the liquid from the container.
To heat the nozzle different type of systems are used based on the type of the fogger. Electric foggers are heated by electricity so they must be plugged into an electric socket to be able to heat the burner and coil in the nozzle. A propane fogger needs a propane gas cylinder for heating. This cylinder needs to be attached at the back of the fogger. When a cylinder is attached a fuel valve must be opened in order for propane gas to flow to the nozzle of the fogger. Propane gas cylinder used on foggers are quite small, which makes propane foggers portable so you can take and use them practically anywhere and there are no restrictions as with electric foggers that need a permanent electric source in order to work.
Propane fogger parts
A propane fogger is a special type of insect fogger that uses a propane gas to heat the burner and coil. Propane gas is stored into a cylinder that gets attached to the back of the fogger. A propane fogger consists from these parts:
- Body and handle – Each of foggers parts is attached to the body of the fogger. The purpose of a fogger body is not only to hold each part together but also to take the insecticide from the container and deliver it to the nozzle. On top of the body there is a handle for holding the fogger. Body and handle of most propane foggers is made from durable plastic. Handles are made as easy as possible to use, so most buttons and triggers are located either on the body or the handle. On the handle and body of a propane fogger you will find such buttons and triggers:
- Fogging trigger – The trigger you are going to use the most is fogging trigger. This trigger is used for fogging process control, or in other words you can start fogging and release a fog by pressing the trigger and stop the fog by releasing the trigger. Each mosquito fogger has fogging trigger of different sensitivity and some foggers are going to output a lot of fog with soft touch on the trigger while other will require to press the trigger multiple time to release the same amount of insecticide.
- Trigger lock – a button that locks or unlocks the fogging trigger. This button is used for safety and prohibits the fogger from accidental insecticide pumping and spraying, which can be dangerous for a person operating the device.
- Igniter –this button creates a spark that lights the coil so it can start to heat up. This process can also be done with a regular lighter or match by lighting the coil from outside of the coil basket.
- Insecticide container – A tank that is located on the bottom of the fogger and holds the insecticide or any other kind of liquid used for fogging. Inside this insecticide jar there is a special pump which starts pumping the insecticide into the coil when fogging trigger is pressed. Also a fogging solution used for fogging can be mixed in this tank.
- Fuel valve – fuel valve is usually located near the propane gas cylinder and regulates the gas supply from the cylinder. Fuel valve needs to be opened in order for gas to flow from the cylinder to the burner and coil. After the fogging process the fuel valve needs to be closed so the gas supply stops, this can be considered as turning the fogger off.
- Coil, spray nozzle and coil basket – The part responsible of turning the insecticide into a fog consists of such parts as coil, burner, spray nozzle and coil basket. These parts are located at the front of the fogger. Insecticide gets pumped trough the burner and coil, where it gets heated before spraying out trough the nozzle. Around the coil is a wire basket that protects the coil and person operating the fogger touching the coil as it can get extremely hot. At the end of the coil there is a spray tip from which the insecticide fog is sprayed out. Under the coil there could be an igniter hole if the fogger is equipped with an ignition trigger. BE CAREFUL WHEN USING A FOGGER AS COIL, BASKET AND SPRAY NOZZLE WILL BE VERY HOT AND CAN CAUSE BURNS IF TOUCHED.
- Propane gas cylinder – Propane gas is used for heating up the burner and coil of the fogger. Besides propane gas some foggers use butane gas for heating. Cylinder needs to be attached to the back of the body of a fogger. Most propane foggers come without a propane gas cylinder and it has to be bought separately. The allowed size of a propane gas cylinder is usually indicated by the manufacturer, but most times a bit smaller or larger cylinder of same type can be used to suite different sized areas.
