Are you considering purchasing an air compressor for your semi-truck tires but are unsure of where to start? The functioning of an air compressor is greatly influenced by size in addition to a few other aspects. It is a fundamental strategy for anyone who is just getting started with utilizing an air compressor and is having trouble choosing the proper one.
Size is strongly related to CFM level and tank capacity because these are the key components of how air compressors operate. Since air compressors come in a wide range of sizes, choosing the one that best suits your needs might be challenging.
In light of this, we have written this post to provide comprehensive information regarding what size air compressor is best for a semi-truck tire and how to choose one. So, better begin with it now:
What size air compressor for semi-truck tires?
Inflating a semi-truck tire isn’t a big yet difficult task to do, you can easily do this whether you are a beginner or an intermediate user. I have used both small and large size air compressors for inflating my semi-truck, and I believe both don’t cause any specific difficulty.
But, yes one thing that you need to do is to work with great care and precautions when you are using a large, heavy-load compressor. Make sure you check the pressure and air and set it as you require for your semi-truck tires because such compressors have a greater tendency.
Meanwhile, if you are looking for a particular answer about the size of the air compressor for semi-truck tires, you should go for a 2 – 3-gallon sized air compressor. It would be sufficient for you only if you are particularly looking for one for this purpose.
If you are getting a 2 – 3-gallon air compressor, it will provide with 25-36PSI level, so make sure to consider that too in mind while purchasing. These can typically be filled from empty tank with even the smallest compressors.
However, larger tires frequently need to be inflated to 100 PSI. At the same time, some portable compressors with lesser operating PSI levels could find this to be too much.
Size-dependent factors to look for in an air compressor for semi-truck tires
Here are some of the most uncommon and neglected factors that you must in an air compressor before purchasing for inflating semi-truck tires which also depends on the size of the air compressor.
1. Capacity of pumping:
Before purchasing a compressor, it is vital to be aware of its maximum pumping capacity. Your money will be completely wasted if you purchase a pump with low pumping capacity because it will not be able to inflate your tires. Talking about inflating the semi-truck tires, to give an exact reading you must look for a compressor with 120PSI.
2. Duty period of compressor:
Most of the compressors stop working after 15-20 minutes and I believe that’s pretty good if you need to inflate your semi-truck tires individually or even at the workshop. You can easily get done even when starting from zero.
3. Length of cord:
When you need a compressor for inflating/pumping semi-truck tires, you need to look for a longer cord to reach all the tires without any inconvenience. For that, I advise you to go for a cord length of 20 feet as it would be ideal, not so short and neither longer to make the assembling tough.
4. CFM of compressor:
The CFM rating of the compressor is yet another key component. How quickly and effectively you can fill your tire is primarily affected by this. CFM and PSI of the air compressor are measured equally with regard to the other. By knowing the PSI, you can certainly get the CFM of the compressor.
CFM of an air compressor should be more than 1 and can go up depending on the PSI.
5. Pressure gauge of compressor:
Before getting into the world of pressure gauges, the air compressor must have a meter for readings. A compressor without a meter is like a blind man doing the job. So, don’t fall for it.
Primarily, there are two types of pressure gauges, analog and the other one is digital. I have used both but as per my judgment and by experts’ recommendation too, you should go for a digital one.
6. Size of tank:
The most important of all, on which all of these factors primarily depend the most. The tank is where it all happens, from its psi to everything. Alongside that, the tank makes a huge difference in the performance of your compressor. It tells you how much time it will take you to store and then pump/inflate your tire.
So, it is the most important aspect of an air compressor. Generally, if your tank is larger, it will take you less time to inflate the tires but at the same time if your tank is large then it will take more time to fill up the tank with air.
For a smaller size air compressor and for occasional use, a 10gallon air compressor will do the job. But, if you want to go for a little larger model, then 3-4 gallons would be more than enough to do various tasks.
Final words:
Air compressors are made for their respective functioning and every compressor varies in its performance because of its construction and use.
As a worker, I frequently receive inquiries about the size of the air compressor. So, I made the decision to post all the important instructions I am aware of online. Above, in this article, I have talked about the size of air compressors for small-truck tires.
