How Does an RV Air Compressor Work?
A compressor has the sole purpose of compressing to fill up pneumatic tires for motorhomes and RVs. How does it do that? Easy – it happens in 3 steps:
- Air Drawing
The process starts with the pump drawing air from outside, which enters through an inlet valve. Every compressor has a piston. This piston is located inside the pump, which never stops drawing air from outside. The air goes directly into the tank.
Once the air is inside the tank, it pressurizes. This happens when the piston draws air,and the tank has to pressurize it all in the same place. Some air compressors use special rotors that pressurize the air and then send it to the tank.
After the air is sufficiently pressurized, no more air will enter the tank. That means it is ready to be discharged.
With a valve similar to the one that draws air inside, the compressor will discharge the air out. Because this air is pressurized, it can fill up pneumatic objects like RV tires.
As you can see, the process for drawing, pressurizing, and discharging air is not hard. Compressors are simpler than they seem.

What to Look Before Purchasing an Air Compressor for RV Tires?
So you’re looking for the best portable air compressor for motorhome, yet you don’t have any idea what to pick. Even after reading our reviews, you’re still sort of confused about which one will meet your standards.
Well, don’t worry. We’re going to help you with that here. Next, you’ll learn about the most important factors to consider before getting an air compressor for your RV:
Size and Weight
If you know the size of the tank, then you can figure out how practical it can be.
But it is not only the size but how much pressure it can handle. For example, large tanks can reach about 80 PSI, but smaller ones can reach 150 PSI with ease. However, smaller ones will empty out faster, so you will need to let them fill up a lot more.
For an RV, you will need high PSI, so we recommend small tanks with tons of PSI. This helps fill up the tank faster and inflate tires with less effort.
With size, however, also comes weight. If you get a giant compressor, there’s a high chance it will be heavy and difficult to use. But if you get a small one, then you’re likely to get a light and portable model.
Be sure to get something with the right size and weight depending on your needs. For an RV, portability and PSI are the two most important factors.
The Right PSI
Even though we already went through some of it, we still need to explain how PSI (pounds per square inch) truly matters.
To give you a general idea, it is what air compressors use to discharge. The more pressure the tank has, the more PSI it will boast. Sure enough, high PSI means faster and easier tire inflation. So we recommend getting as much as you can.
A heavy-duty truck tire air compressor, for example, will have at least 150 PSI, so even the largest truck tires can be inflated. A small model may not go over 90 PSI, which is enough to inflate RV tires.
In short, you should be ready to pick an air compressor that meets your demands. That should be enough to get your tires inflated with ease.
While PSI is a perfect measurement for inflation capacity, it is the CFM that truly tells you how much the compressor can offer.
The CFM (cubic feet per minute) measures the speed at which the air flows inside. Sure enough, the more CFM you get, the faster the air travels from the compressor to the tire. So, high CFM means speedier inflation.
For RV tires, you should go for no less than 2.0 CFM. That should be enough to get all your RV tires inflated with little effort.
Want to know the pressure level of the compressor? Then you need a pressure gauge.
This device will tell you how much PSI the compressor is working with at the moment. An easy-to-read pressure gauge can make your experience a lot easier and safer.
You won’t like inflating an RV tire with more pressure than required and end up damaging it. Similarly, you don’t want to waste any time trying to fill up a tire with less pressure than needed.
As you should know, compressors have two main types to consider: gas-powered compressors and electric ones.
Gas-powered models, for example, use gasoline to work. These are often very potent and deliver exceptional results. However, they’re harder to work with because they need gas. On top of that, they are usually super-heavy and have tons of different components that require constant maintenance.
An electric compressor is way more practical. You only need to connect it with a battery or outlet, and it should do the job well enough. While these are often weaker than gas-powered models, they are way more practical and allow easy carrying.
Here, you will have to pick between the powerful yet bulky gas-powered and the slightly weaker but more portable electric compressor.
A compressor makes a lot of noise. But you can prevent the annoyance by choosing one that doesn’t make that much.
That’s why we recommend models that make anywhere from 40 to 70 decibels. Anything louder than that can be super annoying.
Be aware that the biggest and most powerful compressors make more noise than the smaller and weaker ones.
So if you don’t care much about size and potency, then a small 65-decibel model may be your best bet. But if you don’t care much about noise, then a heavy-duty 80-decibel compressor may meet your standards.
Not many people tend to consider horsepower (HP) as a reliable measure of power. But it is always safe to know.
This mostly happens with gas-powered air compressors. It should have no less than 1 HP if you want a decent experience. Otherwise, the motor and pump are probably too weak to inflate your tires.
As compressors work with high pressures, they tend to get really hot. And that causes their interiors to overheat. The duty cycle tells you how much of that heat they can stand, and how much time they need to cool down before working at full throttle again.
So, the duty cycle tells you how much run time you can get. But duty cycle is measured in percentage.
We recommend at least 10% of duty cycle so you can get 10 minutes of work and then let it rest for 90 minutes. Similarly, a 50% duty cycle means you can get 50 minutes of work and need to let it rest for 50 minutes.
The best portable air compressor for camper will not cost too much. But it won’t be as cheap as you expect either.
You can look at a total investment of about a hundred for a medium-quality model. In case you prefer a high-quality compressor, then you may need to spend at least a couple hundred.
Just be sure to consider all their features and quality and how they match your demands. That will help you pick a sufficiently affordable air compressor that offers what you’re looking for.
