One problem that you might experience with your air compressor is that it starts making a strange noise that sounds like a vacuum cleaner.
If this happens, don’t panic!
In this blog post, I explored the possible causes of this problem and how to fix it.
Fixing an air compressor sounds like a vacuum cleaner
Intake Filter Is Dirty or Blocked
One possible reason why your air compressor might start sounding like a vacuum cleaner is that the intake filter is dirty or blocked. The intake filter is responsible for drawing in outside air and delivering it to the compressor pump. If the filter is dirty or blocked, it can restrict airflow and cause the compressor to make strange noises. To fix this problem, simply clean or replace the intake filter.
Discharge Valve is Leaking
Another possible reason for the strange noise could be that the discharge valve is leaking. The discharge valve regulates the flow of air from the compressor pump to the air tank. If the valve is damaged or worn out, it can cause air to leak from the pump, which will create a noise similar to a vacuum cleaner. To fix this problem, you’ll need to replace the discharge valve with a new one.
Something Wrong with The Compressor Pump
The last possibility is that there’s something wrong with the compressor pump itself. If the pump is damaged or worn out, it can create all sorts of strange noises. To fix this problem, you’ll need to either repair or replace the compressor pump.

What could be causing my air compressor to sound like a vacuum cleaner?
There are several reasons why your air compressor might start making noises that sound like a vacuum cleaner. One possibility is that the intake filter is dirty and needs to be replaced. Another possibility is that the unloader valve is stuck open, which can cause the compressed air to escape and make a hissing noise. Lastly, the check valve might be failing, which can also cause compressed air to escape and make a hissing noise. If you’re not sure what’s causing your air compressor to make noise, it’s best to take it to a professional for diagnosis and repair.

If your air compressor sounds like a vacuum cleaner, don’t panic! There are a few possible reasons for this problem, and in most cases, it’s relatively easy to fix.
In this blog post, we’ve explored three possible causes of this problem and how to fix each one. So before you call in the professionals, see if you can troubleshoot and fix the issue yourself!
