Air Duct Cleaning Equipment: Troubleshooting Fogging Machine Issues

One of the most important air duct cleaning equipment to add to your arsenal, a fogging machine is an absolute sanitization pro if you use it right. Fast and effective, it lets you apply sanitizing solutions and eliminate any odors, thus ensuring complete client satisfaction.

 

However, it can only help you achieve a clean and healthy HVAC system if you find the right way to avoid common performance issues – such as clogs, weak flow, and inconsistent output. 

 

At Heat Seal Equipment Ltd., we not only provide high-quality air duct cleaning equipment such as fogging machines, but we also provide expert advice on how to use them correctly. 

 

In this blog, you will find troubleshooting techniques that will help you deal with clogs, weak fog output, and inconsistent spray patterns. 

 

How To Diagnose & Prevent Common Fogging Machine Problems

An indispensable air duct cleaning equipment, fogging machines can suffer from the occasional hiccup. Here’s how to navigate through clogs, weak flow, and an inconsistent output. 
 

 

Problem #1: Clogs & Their Fix

Clogging is actually the most common fogging machine issue. The good news is it is also the easiest one to fix. 

The primary reason clogs occur can be attributed to the build up of chemical residue inside the nozzles or the lines of the machine. This can accumulate over time, thus leading to narrowed fog pathways and restricted airflow. 

 

What causes clogs:

 

• The use of thick chemical solutions without sufficient dilution 
• Letting the solution sit in the tank for too long after each job
• Not cleaning the machine thoroughly after each use 
• The accumulation of sediment or debris in the reservoir
• Caked up fogging solution at the tip of the nozzle

 

 

What fixes clogs:

 

• After use, remove the nozzle and soak it in warm water. Use a cleaning solution to get build-up off.
• As for the fogger, run it through a neutralizing solution or a tank of clean water to get rid of any gunk. 
• Check the tube for blockages and promptly remove any found. 
• Filter or strain fogging chemicals before use to prevent build-up. 

 

 

What prevents clogs: 

 

Clog prevention is easy. All you have to do is thoroughly flush out the fogging machine you use after every job. A 2-3 minute long flush can prevent 90% of clogging instances. 

 

 

Problem #2: Weak & Inconsistent Fog Output & Its Fix

You can blame weak and inconsistent fog output on low air pressure or chemical flow. If you notice a thin, weak veil of fog emanating from your fogging machine, it is time to stop and inspect the issue.

 

 

What causes weak and inconsistent output:

 

• Decreased air pressure from your compressor
• Loose connections in your machine 
• Partial nozzle blockage
• Incorrectly diluted solution 
• A worn-out air valve 

 

 

What fixes weak and inconsistent output:

 

• Check your duct cleaning air compressor’s settings and make sure the PSI and CFM are optimal for chemical output.
• Tighten any loose airline connections and ensure there are no leakages.
• Clean the nozzle after every use even if there is no blockage. 
• Follow the manufacturer’s instructions when diluting chemicals. 
• Check your fogger’s internal valve for signs of wear and tear, debris or cracks. 

 

 

What prevents weak and inconsistent output:

 

The good news is a weak and inconsistent fog output is almost always the result of a pressure issue. The simplest way to prevent this is to ensure your duct cleaning air compressor is working as it should. 

 

 

 

Conclusion

Your fogging machine works well only when you use and maintain it right. By troubleshooting the common issues we have listed above, you can restore its function back to normal, thus ensuring consistent results during every duct sanitization session.

FAQs 

 

 

Why does my fogging machine spray in pulses?

 

A fogging machine sprays in pulses when there is an air leak or inconsistent chemical flow. 

 

How often should the nozzle of a fogging machine be cleaned? 

 

There’s no fixed frequency. You should thoroughly flush out the nozzle of your fogging machine after every use. 

 

When should I replace my fogging machine’s hoses and seals?

 

You should replace your fogging machine’s hoses and seals if you notice signs of damage, stiffness or air leaks.
