Fogmaster Jr. by Fogmaster company is a compact, general usage ULV fogger that can be used for all sorts of works, starting from removing unpleasant odors and molds from indoor places, to treating stains, mist plants and foliage and also to spray insecticide to fight a mosquito problem. As manufacturer states, this fogger is for those jobs for which an industrial fogger is too large and hand sprayer is too small, to which we can fully relate. This fogger comes in 120VAC and 240VAC models and can be used with both water and oil based solutions.


When compared to other ULV foggers or industrial propane foggers, Fogmaster Jr. 5330 looks very small and compact fogger. It is equipped with just a ¼ gallon (0.95 liter) small solution tank, which compared to more common 0.8 gallon (3 liter) ULV tanks may seem a way too small and may need a frequent refilling. But actually this cold fogger is very efficient and economical, as you can fog quite a large area just with one tank. The discharge rate of the fogger can be adjusted from 0–4 oz (0-118 ml) per minute, which will allow to fog for approx. 8 minutes at full rate, and you probably won’t need to fog at full flow rate. The air compressor is being powered by a ¼ HP, 120VAC or 240VAC motor. The fogger can output particles in size from 15-40 microns. Particle size can be adjusted by controlling the flow rate of the fogger. Smaller flow rate will output smaller particles closer to 15 micron range, while higher flow rate will output larger particles up to 40 micron range.

As mentioned above, the solution container of Fogmaster Jr. 5330 can hold up to ¼ gallons (950 ml) of fogging solution, but you can also get a larger solution container of 0.5 gallons (1.9 l). The solution tank, same as the whole unit is made from plastic materials. The base and nozzle are made from nylon and solution tank is made from a polyethylene, which can store all sorts of fogging chemicals and is easy to clean, same as you will find on many other cold and thermal foggers.

The fogger has got a convenient handle on top of the body, to make the fogger easy to carry around when fogging. On top of the handle there is an on/off switch and on the front there is a flow adjustment valve. On the back of the handle you will find a power cord, which in opposite to other ULV foggers is quite long in 9 feet (2.7 m) length.
