What Are Semi-Truck Compressors?

If you’re reading this, you are probably asking yourself what an air compressor does in a semi-truck. Simply put, it is responsible for supplying compressed air to the suspension and braking systems. However, you may have a few more questions when it comes to your heavy-duty compressors. To help you answer some of those questions, we’ve put together the following article. Read on to learn more about compressors!

What Does A Compressor Do In A Semi-Truck?

The main function of the compressor is to make sure the suspension and braking systems have a supply of compressed air with which to operate. Normally, this type of compressor is driven by your semi-truck’s engine. The system is designed to build up the air pressure for the air suspension, auxiliary components, and brake system. Depending on the model of compressor your truck uses, it will draw filtered air. This will occur one of two ways – it will aspirate naturally directly from the truck air cleaner or at increased pressure from the engine’s turbocharger. Then, the system will compress the air until it reaches the pressure it requires to operate normally.

How Long Does A Semi-Truck Air Compressor Last?

If checked regularly and maintained properly, your compressor can last up to fifteen years. Of course, this will not be the case with every compressor. There are several additional factors that can increase or decrease the life of your compressor, but the best way to ensure longevity is to make sure you make it a part of your regularly scheduled checks.

According to a study done by VMAC air on how long a truck mounted air compressor should last, “the poll results showed a clear winning expectation, with 40.51% of respondents choosing 6-10 years.

When combining those results with the 19.19% of respondents who chose 1-5 years and the 17.76% who chose 11-15 years, a whopping 77.46% of respondents expect their truck mounted air compressor to last within the 1-15 years range.”

How Do I Know If My Semi Air Compressor Is Bad?

There are several things you can look for when determining whether you have a bad compressor or not. Some of those options include:

  1. Your compressor won’t start.
  2. Your compressor won’t stop.
  3. Odd noises coming from compressor.

If you are experiencing any of the above issues, you’ll want to be sure and take your rig to a certified mechanic who can diagnose and fix the issue.
