Air Duct Cleaning Equipment: Maintenance Tips For Fogging Machines

For HVAC contractors, a fogging machine is an absolute must-have. This sanitization pro is not only effective at disinfecting ducts, but it is also useful in applying sealants. A multipurpose machine in every sense of the term, it can continue to deliver dependable performance for a long time to come, provided you maintain it well. 

 

Heat Seal Equipment Ltd., one of the most reliable suppliers of air duct cleaning equipment, including fogging machines, in Ajax, Ontario, is here to help you with that. 

 

In this blog, we will walk you through the essentials of fogging machine maintenance so all you get are flawless results, not frustrating reworks. 

 

 

Why Do You Need To Maintain Your Fogging Machine? 

 

A well-maintained fogger retains its peak performance for a considerable amount of time. It is a great and easy way to protect your investment. 

 

That said, what you should know about foggers is that they work on the principle of precision. If they are unable to produce fine mist that can reach deep into the ductwork to coat its surface evenly, it is a sign of trouble. The same holds true for clogs, leaks and pressure drops. 

 

Overtime, you might notice sealant or cleaning agent residue. Both of these can restrict airflow and alter the size of the droplets your machine releases. 

 

The overall result? Reduced performance. 

 

The overall fix? Regular maintenance. 

 

With regular maintenance, you can prevent each of these issues from turning into a costly problem. It is the smartest way to protect the internals of your air duct cleaning equipment and deliver results that keep your clients happy. 

 

 

How To Maintain A Fogging Machine: Tips From Experts

 

Maintaining your fogging machine is really not that difficult. You just need to follow a few simple steps that Heat Seal Equipment’s experts have listed below: 

 

 

• Clean the nozzles after every session

 

The nozzle of your fogging machine does the main job of transferring liquid converted into fine mist on the duct’s surface. If you want to prevent job-halting clogs, you must do the following after every use: 

 

• Use clean water or a manufacturer-approved solution to flush out dirt from the nozzle 
• Remove any visible residue with the help of a soft brush 
• Do not clean the orifice with sharp tools or wires as it can distort the pattern of the mist 

 

Clean nozzles are integral to maintaining even coating and consistent misting performance so make sure you never skip this step. 

 

 

• Flush hoses and lines thoroughly

 

If not removed promptly, residue from chemicals used to disinfect ducts can dry out and crystallize. This, in turn, can corrode the internal lines of the hose you use with your machine. We recommend: 

 

• Rinse the hose thoroughly under clear water after every use 
• Disconnect and store hoses once they have completely dried
• Before storing them or using them again, inspect them for cracks or leaks, especially near connection points

 

Just like other air duct cleaning tools you use, you must keep hoses clean to maintain stable air pressure and to curtail chances of contamination during your next fogging session. 

 

 

• Inspect seals and gaskets

 

The amount of pressure fogging machines operate under is intense. The seals and gaskets of your machine can bear the brunt of it. That is why inspecting them regularly is critical. We recommend examining all O-rings and seals for signs of wear and tear, cracks, and flattening. 

 

If you find damaged parts, replace them immediately to avoid instances of chemical and air loss. Leaks can significantly reduce the performance of your machine and put people close by at risk of chemical exposure, so do what you can to avoid them. 

 

 

Conclusion

 

We also recommend periodically calibrating the flow and air settings of your machine to ensure consistency in droplet size and mist density. You must also empty its tank completely before storing it in a cool and dry place. Apart from that, the only thing you need to ensure is that you invest in a high-quality fogger.

FAQs

 

Can I use any cleaning solution in my fogging machine?

 

As convenient as it may be, it is best not to. Use only the cleaning solution the manufacturer recommends as it will be compatible with the materials of your machine. 

 

How often should seals and gaskets be replaced?

 

Although a replacement is recommended every 6-12 months, you can replace seals and gaskets sooner if you notice signs of damage. 

 

How do I know if my fogging machine needs to be recalibrated?

 

Signs that reveal your fogging machine needs recalibration include poor coverage, uneven misting, and inconsistent pressure.
