What is ULV fogging?
Ultra-low volume or ULV fogging involves using special machines to produce a fine mist or aerosol. These foggers use large volumes of air at low pressure to compress liquid into droplets, which are then dispersed into the atmosphere.
The greatest advantage of ULV units over thermal foggers, which use heat to produce fog, is that they require a low volume of fluid to generate enough mist to cover large areas. So, they are more economical. In addition, you can control the droplet diameter, which is not an option for thermal foggers. Therefore, you will be able to produce precisely sized droplets to increase their efficiency and meet various needs.

For excellent performance and precise coverage, look no further than the SuperHandy ULV Fogger. It ensures the coverage of horizontal 20′ feet (5-6 m) and vertical 4.9-6.5′ feet (1.5-2 m) to let you quickly treat even a huge area. It is possible because of the high-performance motor powered by a Li-ion battery. The battery is easy to charge up, and you can replace it over time when it wears out to prolong the operation time.
I like its wireless and backpack style, so you may find this item more convenient than Curtis Dyna-Fog Hurricane ES. The padded and wide straps reduce fatigue, while cushioned and meshed supporting pads improve airflow.
The tank is spacious – 2.6 gallons, enough to cover an area of 25,000 square feet. This device distributes the solution fast and ensures intense penetration. In addition, there is a fine misting control feature that allows you to adjust disbursement from the range of 0 to 50 microns.
The SuperHandy ULV Fogger sounds like a vacuum but does its job well. My only concern is that it blows only when you hold the nozzle at your waistline or lower.

How to use a ULV fogging machine?
When working with a ULV non thermal fogger, you should follow simple steps to ensure your effort brings the desired effect and doesn’t threaten your health.
So, you should first care about your safety. Consider wearing protective clothing and gear to eliminate contact with chemicals. Wear a long-sleeved shirt, pants, and gloves. Make sure you have goggles and a respirator on.
When you are fully equipped, it’s time to fill the reservoir with mixed pesticide solution. Mix only the amount you plan to use, as storing a mixed product is not desirable. I always recommend following the label instructions of the chemicals you have at hand to ensure they work nicely.
Adjust the flow rate at the lowest setting before you turn on a ULV cold fogging machine. Then, turn it on and regulate the flow rate to the necessary level. Next, direct the fogger’s nozzle to the area that requires treatment with the solution.
