The Comparison of Some Popular Electrostatic Backpack Disinfecting Sprayer in Market

As we know that most surfaces have a negative charge and the opposites attract. Electrostatic spraying adopts this theory exactly. Simply speaking, it just charges liquids as they pass through a nozzle. And the liquid actively seeks out surfaces, sticks to them, and even wraps around to coat all sides. This also means hard-to-reach corners and undersides of surfaces get disinfectant.
We have studied electrostatic handheld disinfecting sprayers previously. Hereby let’s talk about some of the popular electrostatic backpack disinfecting sprayers in market. Despite the differences between them, they did have one thing in common. The electrostatic backpack disinfecting sprayers can store more disinfectant in one tank than handheld units. They’re great for buildings larger than 5000 sq. ft, allowing users to cover larger areas faster. It is a perfect choice for school, hospital, church, station etc. disinfecting. Let’s get to know them one by one.
There are several commonly used backpack sprayers in the market listed as following:
I. Victory cordless backpack sprayers
II. EMist backpack sprayers
III. EISolutions backpack sprayers
IV. Clorox backpack sprayers
V. Ryobi backpack sprayers

I. Victory cordless backpack sprayers

Victory Innovations is an American company that was founded to develop a patent pending cordless electrostatic sprayer delivery system in 2016. Even it is new, they did make very nice products. Their professional Cordless Electrostatic Backpack Sprayer is designed to allow the professional to cover up to 23,000 square feet on a single tank of fluid. Besides, they have features and advantages are as follows:
electrostatic backpack disinfecting sprayers


a) 16.8V 3400mAh Lithium-Ion battery and 16.8V charger.
b) 3 in 1 nozzle can achieve different misting requirements.
c) 2.25 gallon tank capacity.
d) 12inch Extension Wand
e) Compatible with any water soluble
a) Time and labor saving.
b) Less liquid, more surfaces covering.
c) Unique and patented technology provides effective and even coverage.

Features of the Nozzle

Here Victory uses two fine misting nozzles and one flat fan nozzle in order to achieve effective disinfection. Honestly speaking, to obtain a good spray performance, the selection of nozzles and pumps are very important. Please refer to see our Advices on Selection of Misting Nozzle and Pump for Sterilizing Sprayers.

There are three major types of spray tip for Victory’s sprayer:

1. 3 in 1 nozzle: one misting nozzle with 40 microns spray, one misting nozzle with 80 microns spray and one flat fan spray nozzle with 120 microns spray.
2. Single head spray tip: misting nozzle or flat nozzle mentioned above is available for the single head spray tip. The spray tip can be easy interchangeable by a special tool.

3. Nozzles with different spray performance are identified by color spots, white for flat nozzle, while red for finest spray with smallest flow rate and green for fine mist with relatively bigger flow rate.

II. EMist backpack sprayers.

Emist, based in Texas, was found on a legacy of electrostatic science and technology, manufactures several types of electrostatic sprayers, as well as the accessories. Their EX-7000 is a high impact and better performance electrostatic backpack sprayer. It only weights 8.1 pounds bare and only 14.9 pounds fully loaded.

a) 14.4V Lithium-Ion battery and 14V charger.
b) Fine misting nozzle applied.
c) 0.82 gallon tank capacity, compatible with any water soluble.
d) Hydroelectric Cord with convenient wand hook hangers.
a) High-touch coverage of 44,300 sq.ft.
b) Light weight of 14.9bs, easy for handling.
c) Grounding not required, cordless and any water soluble available makes it easy to operate.

Features of the Nozzle

Again, fine misting nozzle is very practical and widely used in backpack disinfecting equipment due to its ability of generating very fine mist in a long run. The droplet size of the disinfectant is quite important in practice. Please refer to The Effect of Droplet Size in Disinfecting Application.
Emist use a fine mist nozzle to produce small particles. The hex plastic housing of the mist nozzle can be easily assembling and dismantle. Generally speaking, if the spray particles are smaller, the mist is softer and the spray distance is shorter, therefore smaller coverage for the sprayer. The Emist sprayer have the larger coverage compared with other brands due to the inbuilt turbo fan in the spray gun. The wind generated by the turbo fan can push the mist farther.

III. EISolutions backpack sprayers.

EISolution, established in 1974, is an US company headquartered in Tulsa, Oklahoma, with a 35,000+ sq. ft. production facility, who delivers creative solutions for electrostatic sprayer systems, electric motors, custom controls, and customized electrical buildings. Their EISX100 electrostatic sprayer is a powerful one with the tank capacity of 4.2 gallons and fully loaded weight of 53 pounds.

d) 75% cost savings when compared to buying traditional disinfectants.
e) 90% cost savings on labor

Features of the Nozzle

EIsolution does upgrade the sprayer tips/nozzles to increase atomization of the fluid, providing an evenly distributed application. They offer multiple customized nozzle options to meet the customer's specific needs as follows:
1. Single head spray tip with different mist nozzle
The different spray tips are identified by body color.
Blue Single Tip – Extremely Fine Mist

Each type of nozzle have three pieces structure, which consist of tip holder, locking nut and spray tip. The spray tip can be interchangeable

2. Brass Triple Tip - Fogger Nozzle

For higher pressures, triple nozzle spray tips are available for finest spray with much denser mist. But from our point of view, the brass body is not good for corrosion resistance since the corrosiveness of most disinfectant.

3. Spray lance with several spray tips

The multi-nozzles spray lance can provide the largest coverage and highest disinfection efficiency. The nozzles used for the spray lance are the mist nozzles mentioned in type 1.  
This is quite brilliant actually. With this move, they did maximize the use of the nozzles to achieve the best performance for all kinds of customers anywhere they need.

IV. Clorox backpack sprayers

Features of the Nozzle

The Clorox’s sprayer use the two fluid nozzle for atomization, which need compressed air to produce fine mist. Generally speaking, the air atomizing nozzles have better spray performance compared with single fluid nozzles, smaller droplets, more uniform mist. The disadvantage of the pneumatic nozzle is the compressed air supply, in-built air compressor in sprayer or external connection of compressed air in needed.
