NanofogĀ® Foggers - The most advanced ULV foggers for aerial disinfection

Foggers FAQs


What products can be used in a EasyFog / Nanofog fogger?

EasyFog / Nanofog foggers are capable of atomizing light liquids -- both water- and oil-based -- including pesticides, deodorants, disinfectants and, of course, water. Heavier liquids can also be fogged, providing their viscosity and surface tension is not too great. (Viscosity and surface tension affect both output rate and droplet size distribution.)

However, do not fog a flammable liquid due to the risk of fire or explosion. Standard EasyFog / Nanofog products use an open frame motor, which is not explosion-proof. (If an explosion proof motor is required for a fogging application, contact the factory to discuss a custom unit for the application.)

What other safety factors should I consider?

First, read the chemical label to make certain that fogging is appropriate for your chemical. Most chemical labels, and all pesticide labels, have instructions for use, application rates, and sometimes even the application equipment to be used.

If the chemical label has application instructions, follow them. If the label does not have application instructions, use caution and common sense, remembering that some chemicals may cause injury, or even death, if used inappropriately.

Remember also that the small droplets of a fog can travel a great distance before settling or dissipating. Be sure to consider the safety of animals, objects or other people that may be in, or downwind of, the application area.

In summary, know what you are applying. Never fog an unknown chemical.

What protective equipment should I wear when fogging?

That depends on the circumstances of your application, the potential routes of exposure (including inhalation, skin absorption, and dissolution in saliva or nasal or eye fluids) and the properties of the chemical you are using.

A material safety data sheet (MSDS) is often enclosed with chemical products. Prepared by the chemical manufacturer, the MSDS contains safety and technical information about the product (including corrosiveness, flammability, toxicity, reactivity, first aid, etc.). Your salesperson or a representative of the chemical manufacturer can help you interpret the MSDS.

You can also write EasyFog / Nanofog for application and safety information. Send a letter, fax or e-mail -- no telephone advice is given -- describing the application and chemical you propose to use. Enclose a copy of the chemical label or instructions for use, and a copy of the MSDS if you have one.

We will try to be helpful, within the limits of our knowledge. However, we do not manufacture or sell chemicals, and we are not familiar with all chemical products. The EasyFog / Nanofog Corporation cannot regulate the use to which you may put the equipment it manufactures and assumes no liability for any direct, indirect or consequential damage which may arise out of such use.

What is the particle size of your fog?

In general, the output of EasyFog / Nanofog foggers falls in a range from a near-invisible ULV dry fog (7-10 micron diameter), to an intermediate fog (15-20 microns), to a heavy, wet fog (30+ microns). Droplet size differs with nozzle design, fogger model number, liquid discharge rate and, of course, the liquid being applied.

For a given model, a lower liquid rate yields smaller particles; at equal rates, liquids with lower surface tension and viscosity yield smaller particles. In general, an oil-based fogging solution yields smaller particles than an aqueous one.

Many EasyFog / Nanofog foggers provide control of liquid rate and particle size. See the specifications page of each model for data on its droplet size range.

How do I measure fogger output rate?

We include calibration procedures with each unit. These vary slightly for different models, but here's a general approach:

1. Put some fogging liquid in a measuring cup or graduated cylinder

2. Put the liquid suction line into the cup or cylinder

3. Turn on the fogger

Adjust the output valve to get the droplet size you want for your application (the valve simultaneously controls liquid flow rate) Calculate the liquid output rate. Measure the time needed to discharge a known volume, then divide that volume by discharge time to compute the flow rate in ounces per minute (or cc/min).

Remember, first adjust the fogger for the desired particle size, then measure the liquid flow rate which produces that size output in your setting.

Do not calibrate a fogger with a dangerous chemical (or an expensive one). Instead, make an approximate calibration, using water (as a substitute for a water-based product) or light kerosene (for an oil-based one). After you put the fogger into service, use actual data on liquid consumption and fogging times to refine your calibration.

How large an area can I treat?

EasyFog / Nanofog foggers can treat a large area very quickly; 4-5,000 cubic feet per minute is fairly typical for a ULV (ultra low volume) application at a conventional dosage rate (1-2 oz/MCF).

How much chemical should I apply (or how long should I fog)?

For a space treatment, see the chemical label. It will usually specify an application rate (for example, ounces per 1000 cubic feet of space treated). After you have adjusted the fogger particle size and measured its output rate, determine the fogging time as follows:

1. Multiply room length by width by height (all in feet) to calculate room volume (in cubic feet).

2. Divide room volume by 1000 to convert to thousands of cubic feet (MCF).

3. Multiply room volume (in MCF) by the application rate recommended by the label (ounces per MCF) to get the required chemical quantity (in ounces).

4. Divide chemical quantity by the fogger output rate (oz/min) to get application time (in minutes)

For a surface treatment, follow a similar procedure but use the surface area of the treatment area rather than room volume. Some chemical labels give qualitative application rates -- for example, spray until damp, or spray until run-off occurs; follow those instructions. When making surface applications, treat uniformly to cover all surfaces evenly.

Lastly, such "open air" applications as odor control at a landfill or sewage treatment plant involve repeat discharge under the control of a timer or gas monitor. The effects of temperature, odor intensity, wind direction, chemical efficacy, etc. cannot be predicted, so you will have to experiment to determine optimum chemical dilution rates and cycle times.

What chemical does EasyFog / Nanofog recommend or sell for [my application] ?

The Ideal In Fogging Systems does not sell or recommend specific chemicals. However, many of our distributors sell or manufacture chemicals, and we can refer you to them for assistance.

How do I maintain my fogger?

Generally, Ideal In Fogging System products require little maintenance. Keep your fogger and air filter clean. After using, drain and rinse tank and run fogger head a minute or two to clear remaining liquid from internal lines. See maintenance for other tips.

Where can I go for service?

Some distributors provide repair services. Also, Ideal In Fogging System provides repair services (for Ideal In Fogging System products only) at our factory. We charge for parts only (no labor charge).

What about warranty service?

We do warranty repairs at our factory (shipping instructions).

I do my own service. Where can I buy parts?

Many distributors keep some parts on hand, or you can purchase parts from Ideal In Fogging Systems. A numbered parts drawing is enclosed with each product shipped. We can fax or Email you a copy if you need it.
