This ULV fogger is manufactured by a well known company called Fogmaster that are producing various high quality fogging tools. This particular model by Fogmaster is called Micro Jet 7401. It is an ULV fogger that uses cold fogging techniques to atomize solutions into small particles. The fogger can output particles as small as 7 micron size, which is close to what thermal foggers produce, this allows to use the product for applying various types of liquids. Fogmaster Micro Jet 7401 is a universal fogger that can be used for wide range of applications indoors and outdoors. Device can be used to output liquids in form of a fog, wet mist or spray and can take both water and oil based solutions. Some of the ways to use the tool are for mosquito and other insect control, to eliminate bad odors, for mold control and to spray sanitizing liquids. The fogger is being used in many different areas such as commercial buildings that include warehouses, offices, shops and other places as well as individual houses and backyards when controlling insects. Fogmaster Micro Jet 7401 fogger is made in the USA.


Fogmaster Micro Jet 7401 fogger is a feature rich tool that can be used in wide range of applications. The body of the fogger same as the solution container are made from an aluminum and the fogger is in a shiny metallic color. It has got a handle on top of the unit so you can carry it around more easily. The fogger itself is powered by a strong 1 HP motor, which is available in 120V and 240V versions. The motor is powering a strong fan that atomizes and sprays solutions in up to 30 feet (9 m) distances.

The fogger has got a counter rotating nozzle that atomized fogging liquids into extremely tiny particles. Although this is an ULV fogger it can produce particles from size as small as 7 microns, which basically is fog to wet mist with particles in 30 micron size. Micro Jet fogger allows to adjust the flow rate of solution from 0-8 oz (0-237 ml) per minute thanks to the nine turn flow control valve that is located on the side of the tool. Adjusting the flow rate will also adjust the particle size fogger outputs, higher flow rate produces larger particles and lower flow rate will output solution in smaller particles. When you have adjusted the valve to appropriate setting you can use calibration to choose the same setting again. The tool also has got a valve lock feature, so you can lock the valve into the correct position when leaving the fogger to work automatically for longer time. Because the fogger has got such a powerful engine that produces a high stream of fogging solution, this tool can fog couple thousand square feet large area in just a minute, which is very useful when fogging larger outdoor areas for mosquito control.

The fogger can be used to spray both water or oil based solutions, so it can be used with water, sanitizing solutions or insecticides. For storing fogging liquids the fogger has got a 1 gallon (3.8 l) large solution tank that attaches to the bottom of the fogger. The solution container can be easily detached from the fogger which allows for easy filling of fogging liquids as well as easy cleaning of the reservoir.


This ULV fogger is really a universal tool thanks to the adjustable flow rate, particle size, powerful engine, large solution container and ability to spray different types of solution. The Fogmaster Micro Jet ULV fogger will produce dry fog which is useful for mosquito control, mist that can be used for mold or odor control and a wet spray to humidify a room, greenhouse or other area. The fogger is able to atomize the fogging liquids into such small particles thanks to a powerful fan and a nozzle specifically made to create small particles with a high air flow produced by the fan. The flow rate and particle size the fogger outputs can be regulated with a flow valve on the side of the fogger. A lower flow rate of 1-3 oz (30-89 ml) per minute will produce dry fog and high flow rate of 6-8 oz (177-237 ml) per minute will produce heavy, wet mist.

The fogger works with electricity and comes with an electric cable that needs to be plugged into a regular electricity outlet in order to power the fogger. If you need to fog a larger outdoor area, use an extension cord made for use outdoors. Before fogging detach the solution reservoir and fill it with according fogging solution and attach the tank back to the fogger. Plug the tool into electricity and you can start fogging. Adjust the liquid flow rate by turning the flow control valve for your fogging solution and applications needs. If you want to leave the fogger to work automatically, you can also adjust the angle of nozzle so it fogs into correct place. When done fogging, remember to clean the fogger and solution tank from any leftover fogging liquids and chemicals. Also clean the outside of the fogger with a soft cloth.
