When it comes to foggers, ultra-low volume foggers (ULV foggers, for short) are one of the best options to choose from. These foggers are able to produce a much finer mist than any propane or electric foggers. This means you can use them indoors and outdoors. They are perfect for many different applications, ranging from mosquito control to disinfection.

If you already own a ULV fogger or are about to purchase one, you’ll need to know how to operate it properly. This is the key to efficient fogging and great results. So, here is our ULV fogger operation manual with some tips and tricks about how you can get the most out of your ULV fogger.

Turning On and Using Your ULV Fogger

Before you start fogging, you’ll need to buy yourself a ULV fogger. Once that’s done, there are a few steps to follow before you can start your fogging treatment.

1. Plug the fogger in.

First things first, to be able to work a ULV fogger, you’ll need to connect it to a power source. This means that you simply need to plug the fogger’s power cord into an electrical outlet. Then you can start fogging.

But, before you do this for the first time, make sure you check the voltage your fogger requires. You don’t want to plug a 110-volt fogger into a 220-volt power outlet or vice versa.

2. Calibrate the fogger.

After you have plugged the fogger into an outlet, you can take the next step. It’s time to calibrate your fogger. What this means is that you need to use the adjustment knobs to achieve the flow you want.

As you increase the flow rate, the droplet size will increase, too. Larger droplets are more suited to applying disinfectants or similar chemicals because these settle better on surfaces. Smaller droplets and a slower flow rate are better for insecticides or pesticides. This will ensure they stay in the air longer and can better kill insects.

3. Fill the fogger’s tank.

Of course, you’ll need to also actually fill the tank with the liquid you want to use. This will depend on the ULV model you own. You’ll either have to open the valve on the tank or detach the tank entirely.

Make sure the liquid you want to use is suitable for a ULV fogger. Try not to mix any liquids in the tank; it’s better to do this beforehand. Also, don’t overfill the tank. Once the tank is full, just close the cap or valve (or screw the tank back on the fogger) and you’re good to go.

4. Turn the fogger on.

Now that you’ve completed the previous steps, you can turn the fogger on. Using the liquid of your choice, you can fog either indoor or outdoor areas.

Make sure that you calibrate the fogger before you turn it on. If you do this in reverse, you’ll risk getting sprayed in face or fogging an area you didn’t want to.

Turning Off and Storing Your ULV Fogger

After you’ve finished fogging, there are a few steps to follow to turn the fogger off completely. These will also ensure that you maintain it in good working condition so that it’s ready to use the next time you need it.

1. Turn off the fogger, beginning with the flow rate knob.

For most foggers, there’s a proper way to turn them off. To do this correctly, you’ll need to turn off the flow rate adjustment knob first. This will make sure that the fogger stops emitting fog.

Only then should you turn off the power completely. If you do this the other way around, the liquid could accidentally drip into the fogger’s hose. That, in time, could destroy the fogger’s motor.

After the fogger is turned off and unplugged, you should open the cap of the liquid tank to let it air it out a bit.

2. Empty the tank.

After you’ve completed the previous steps, you should always empty any remaining liquid from the tank. Then flush it with water to ensure that no chemicals remain in the tank. This will stop the leftover chemicals from damaging your fogger and tank.

3. Check the fogger for damage.

You should check over parts like the spray hose and electric cord quite frequently to ensure that they haven’t been damaged during use.

4. Put on the protective nozzle.

The final step is to put on the protective nozzle and store the fogger in a safe place until the next time you need it. It’s best to keep your fogger in a cool, dry location, out of direct sunlight.

Extra Tips for Getting the Best Results

Most ULV foggers have filters to protect the motor from the fogging liquid. You should also replace these filters from time to time to keep the fogger working at full capacity.

Fogging in the mornings or the afternoons – in low wind and dry conditions – is the best option to ensure that you get the best results.

hi there,
I have a ulv fogger 4.5litre
if you are disinfecting stairways and hand rails or doors ,skirtings etc do you need to wipe all areas after fogging or just leave and settle till dry ? also if you put it on low and keep fogging area low will it not set off fire alarm ?

    InsectCop

    No wiping is needed, simply leave the windows open, so the area is well-ventilated and will dry faster. Be careful with the smoke alarm, as it can happen with any type of spraying, as long as you’re doing it too close to the device. We suggest not letting the fog get to it, in which case it should be fine.

How long do you leave it to dry before you can enter room?

    InsectCop

    It depends on the environment, and we also suggest checking the instructions on the label of the solution you’re using.

GOOD MORNING, I have an H-5 ULV DEVICE and I am using desinfection liquid.
I have doubts about which program to use. For example, for a room of 50 m2, what program do I use? I am using number 2.

    InsectCop

    When it comes to disinfecting, we’re no experts, therefore, we suggest consulting professionals to make sure you get advice that keeps you safe!
