The GSPSCN Silver is a decent 12V air compressor, offering RV families a reliable system for inflating their tires. Traveling across the country will be more enjoyable because RVers no longer must worry about poorly maintained or inaccessible tire air services.
I like this heavy duty air compressor’s dual cylinder design, pumping out 2.12 cubic feet of compressed air per minute. Inflating a nearly flat tire to 35 PSI should not take more than 90 seconds, enabling campers to adjust their wheels and get on the road quickly. I also do not worry about where I can use this product because its maximum PSI rating is 150.

What to Look for When Buying an RV Air Compressor
Before buying an RV air compressor, there are many factors you need to consider. Below, we’ll discuss some of these things to help give you a better idea of what you’re looking for in a high-quality RV air compressor.
Understanding what tank size you want is essential to getting the best RV air compressor for your circumstances. See, with these products, the tank size affects the overall performance of the air compressor.
For example, it indicates the maximum volume of air your air compressor can hold. Therefore, the bigger the tank, the more air it contains. But as the tanks get bigger, they get harder to transport.
And since you probably want to take the air compressor with you, you need one that’s easily moved. Due to this, you should search for an air compressor with a smaller tank but with a high PSI.
Pounds per Square Inch (PSI) and Cubic Feet per Minute (CFM)
PSI or pounds per square inch is a metric that measures air pressure. In this case of an air compressor, this rating will tell the amount of pressure it can fill your tires up to; there will also be a PSI rating for your tires, which you can find on the tire’s sidewall.
With this in mind, you’re going to want an air compressor that has a maximum output high enough to fill your RV’s tires. Therefore, getting an air compressor with a higher PSI rating than your tires is essential.
Along the same lines, The CFM or cubic feet per minute is the rating that tells you the airflow rate of the compressor. In other words, the higher the CFM, the faster your tire gets filled.
Both of these two metrics are usually presented together on air compressors. For example, let’s say your tire requires 75 PSI and you find an air compressor that has the following CFM and PSI ratings “5.0 CFM @ 90 PSI”. In this case, this air compressor would be a good purchase for your RV tires.
Hose and Power Cord Length
The high quality RV air compressors will have longer cords and hoses to allow you flexibility. In general, the hose length on air compressors varies significantly from 4 inches to about 30 feet.
Honestly, I couldn’t imagine getting an air compressor with a hose that’s only four inches long. But this is an outlier, as usually, an air compressor’s hose is around twenty to twenty-six feet long. I’d recommend getting a house around twenty-four to twenty-eight feet long.
Along the same lines, the length of the powers cords can have a massive impact on your experience with an air composer. So, make sure these cords are long enough to give you some wiggle room: around twelve to fifteen feet should suffice.
As you would expect, certain types of RV air compressors can be extremely loud. And since you’ll be in close vicinity to the air compressor, the noise level is something you must consider. Therefore, it necessary you know the exact amount of decibels each air compressor you’re considering emits.
In today’s market, the average amount of noise emitted from an RV air compressor is between 40 and 90 decibels. If it were I looking for one of these products, I’d want an air compressor that emitted noise at a level of 65 or lower decibels.
To put a 65-decibel noise level into perspective, it would be like a what vacuum cleaner or hair dryer could produce. Not ideal, but something I could tolerate.
One aspect buyers tend to underestimate is the weight of the air compressor. Please don’t be one of these people. You’re going to need an air compressor that you can move around and store easily.
After all, some people will see the word portable and think it immediately means you can pack it into your RV and go. Then, they get the air compressor in the mail and its over 40 pounds.
Therefore, it’s paramount you research the exact weight of each air compressor you’re considering. I’d recommend an air compressor in the ten to fifteen pound range for easy portability.
Other Important Factors to Consider
What is an RV Air Compressor?
An RV air compressor is definitely a must-have on any trip outdoors while you are driving your recreational vehicle. Prior to preparing for a road trip, you need to ensure that the tires of your vehicle are well-inflated. You can make that possible with the help of a well-functioning air compressor designed for RV use.
Note that in case your tires suffer from under-inflation, you need to get into a gas station right away in order to bring back its pressure. Keep in mind that if you don’t then there is a great risk for excess heat to accumulate while driving. This can lead to the malfunctioning of your RV tires.
Another thing to remember is that an excessively low air pressure has a negative impact on the durability of your RV’s tires. This specific scenario also has a negative impact on the handling and braking systems of your recreational vehicle. However, you should also prevent the over-inflation of your RV tires.
Note that an excessive inflation might lead to the tires sinking easily into the loose sand as well as in trail dirt or mud. Because of this, a good RV air compressor is one of the things you definitely need in your next travels. Just makes sure that you choose an air compressor, which is not too heavy.
Check the weight of your chosen air compressor so you have a guarantee that you are buying one, which is portable and light enough that you can easily carry it around with just your hand. You do not want to bring a device, which is up to a hundred pounds in weight in your travels, do you?
It would be best to look for an air compressor, which is just less than 40 pounds, including its wheels. The good news about portable compressors is that aside from being lighter, they are also smaller in size plus you will never have problems storing them.
How Does an RV Air Compressor Work?
One of the major functions of your chosen air compressor is to inflate your tires to the right pressure. This means that it tends to work once it inflates the tires of your RV, camper, or trailer. It is a device, which compresses air as a means of providing power to pneumatic or air tools.
An air compressor can be powered by either gasoline or electricity. It is usually composed of two principal parts – the cylinder and the piston. The motor of your chosen air compressor will drive air into a storage tank. It then pressurizes the air.
The piston will force more air to the tank, causing the pressure to increase until it gets into the highest level. If that happens then the compressor will stop and make the tires ready for use.
You will also find the compressor useful when it comes to filling bikes, pool toys, motorcycles, and air cushions, among many others that require air filling. When it comes to learning how an air compressor works, take note that its overall quality and effectiveness is also actually dependent on its ratings.
One of the ratings you have to familiarize yourself with is the CFM (cubic feet per minute). This specific rating or value is helpful in measuring the speed through which the compressor delivers the air.
This means that if a compressor has a higher CFM rating then there is a great possibility that it is more powerful than those who have a lower CFM rating. Another vital rating that definitely has a say on how an RV air compressor works is the PSI (pounds per square inch).
This specific rating indicates the specific force through which your chosen air compressor delivers the needed air. In terms of recreational vehicles, a 40 to 90 psi is helpful in performing its function.
There is also what we call as the HP (horsepower). This specific rating is important in the way your air compressor works because it measures the mortar’s working capacity. Note that it is the mortar, which is used in driving the pump of the compressor.
Also, take note that choosing a device with a higher HP also means that you will enjoy a higher CFM from it. Aside from some important ratings, the actual size of the compressor’s tank also has a say on how it will work. It is because the size of the tank can determine the max volume of air that your compressor is capable of holding.
Such volume is often measured in the form of gallons. However, you should try to stay away from large tank sizes as much as possible. Note that while larger tanks are extremely great options, you will notice that a much smaller one is ideal, especially if you are planning to use it in your motorhome or RV.
It is mainly because small ones can promote or facilitate ease of transport. Make sure, however, that the compressor, despite having a small tank, still comes with a high PSI. It is mainly because a small tank size combined with a high PSI means that the compressor will recharge continuously. This can lead to a prolonged operating time.
Types of RV Air Compressors
The type of air compressors recommended for RVs are the portable ones. It should be noted that the types of portable RV air compressors are often based on certain factors, like their horsepower, CFM, and PSI. You can also determine the specific type of portable air compressor you need based on the size and weight.
What is good about a portable air compressor is that it is capable of maintaining the right balance in supplying power for the quick and efficient inflation of tires. They are also stored in a package, which is small enough that you can easily put it in your garage, shed, or car’s boot.
When it comes to choosing the right type of portable air compressor for your need, take note that your choices will vary based on the size. Note that there are different sizes of this device in the market with each one having a different set of specifications, air compression methods, and features.
You can go for larger but still portable air compressors that come with tanks. This is where the device will store the compressed air, pressurize it then feed it through an air hose as a means of inflating the tire. You can also go for really small ones. They come with smaller tanks.
With that, you can only use them to pressurize the air prior to delivering it with the help of an air hose. With that, it is safe to say that its motor will always run when it operates. In terms of their interiors, the small-sized portable air compressors can be expected to work with the aid of their screw-type machinery.
This allows two big screws to turn together as a means of creating a vacuum designed to suck air. This is a major help in allowing the small and portable compressor to work efficiently.
Tips in Using the Air Compressor to Inflate Tires Correctly
When it comes to inflating your RV’s tires with the aid of an air compressor, there are certain tips that can help you achieve the best results. The whole process of inflating a tire with this device is actually straightforward. In fact, most models can do up to 99 percent of the job, provided they feature a pressure auto-cutoff mechanism.
In this case, you just need to connect the air compressor into the tire valve then set your preferred pressure. Once done, you can expect the device to work. You can also ensure that you will get the best results out of inflating your RV tires with an air compressor with these tips:
Ensure that there is a tire chuck – In most cases, modern models feature all the attachments and tools required in inflating your RV’s tires. It is important that you know how to take them out straight from the box. It is also necessary that there is a tire chuck around prior to starting the inflation.
A tire chuck refers to a small tool, which connects your tire’s valve as well as your air hose’s nozzle. It works in depressing the small valve switch that you can find inside the tire’s valve. This lets the air flow. It would be best to look for a compressor with a tire chuck as it promotes ease in using the device to inflate your tire.
Make sure that the compressor stays dry – While most air compressors are designed in such a way that they can handle a lot of beating, you still have to remember that it has its number one enemy, which comes in the form of moisture.
Because of that, you need to ensure that your air compressor stays dry whether you are using or storing it. Note that this is still a device, so there is still a risk for it to get shorted in case it is wet when you are using it. In addition, it usually comes with rotating metal screws that tend to suck air.
Putting it in an environment, which is rich in moisture, can, therefore, cause these screws to accumulate rust. This might also fuse the screws together, which can lead to the compressor breaking down.
Monitor the pressure – Most of the modern air compressors for RV today feature an automatic cutoff mechanism, which is extremely beneficial as it disconnects the device automatically each time it gets into the PSI you have set.
However, if you bought an air compressor without this feature, then it is necessary to monitor the pressure while the device still operates. It is necessary to keep track of the pressure, especially if your preferred PSI is actually close to the maximum level that your chosen device can handle.
These tips are just simple but they actually work wonders in ensuring that your chosen RV air compressor will work based on your preferences.

You need an RV air compressor for a vital but straightforward reason: you don’t want your trip ruined by a flat tire. Due to this, getting an RV air compressor could solve all your problems and make sure your tires are inflated to their proper level.
After all, under inflation/over inflation can cause a heap of problems and with the right air compressor, none of these issues would ever have the chance to ruin your vacation. In the end, getting one of these products is just a practical, logical investment.
How long does an RV air compressor last?
The average motorhome air compressor lasts at least ten years. However, it is not unusual for high-end units and well-maintained air compressors to extend their longevity beyond two decades.
Camper air compressor owners must read their user guide to determine their respective unit’s limitations. Observing the manufacturer recommendations can extend its lifespan, allowing RV families to use the device for several decades.
Some tips for maintaining air compressors are:
- Fill them with the correct oil amount and lubricate the devices when necessary.
- Clean the air intake filters weekly if the compressor is put in dusty areas and replace them after 1000 hours of operation.
- Every time you change oil, clean the oil filter as well. Eventually, this filtration device will need replacement as well, usually after 6 months.
Does the tank size limit the usage of an RV air compressor?
Yes, tank size can limit the usage of an RV air compressor. RV owners must realize that the tank’s only function is to store air. The motor or pump compresses the air to inflate tires and perform other activities, such as spraying paint.
Hence, the larger the air compressor tank capacity, the more air the system can compress for different applications.
Air compressors for van life can accommodate four to six gallons of air, which is sufficient for the average RV family. After all, RVers do not inflate their motorhome tires daily.
Other activities that might use the air compressor include pressure washing, dust blowing, and expanding portable swimming pools. However, these uses are only occasional.
Most RVers pick an air compressor with a cubic feet per minute (CFM) rating of not more than four. A cubic foot is equivalent to about 7.48 gallons. Hence, a six-gallon air compressor with a 2.7 CFM airflow volume delivers about 20.2 gallons of air per minute.
RVers who want continuous airflow for multiple tools should consider an air compressor with at least 16 CFM and at least a ten-gallon tank.
What size air compressor do I need to inflate RV tires?
Well, it depends on how you want to use the air compressor. For instance, if you’re going to transport the air compressor around with on the tire, I recommend investing in an air compressor with a small tank.
See, the larger tanks can be tough to transport around: they can be quite heavy. And since you’re going to want the air compressor in your RV in the event something goes wrong, it doesn’t make sense to lug around a larger tank.
However, if you get an air compressor with a small tank, it’s essential that it has high PSI. In doing so, you’re ensuring that you won’t have to wait around for hours as your tires get inflated.
Which one is the best? (Viair 400P-RV and 450P-RV, Viair 400P vs 400P-RV)
Personally, I will pick the Viair 400P-RV. But I think you should check Viair 400P vs 450P RV.
How to maintain and check RV tire pressure?
The easiest way to maintain your tire pressure is by checking it every time you take your RV out on the road. And this doesn’t just mean looking at the bulge of the tire or hitting it with a trucker bat.
You need to buy a tire pressure gauge such as this one and use it to find your tire’s true pressure level. And with this product, it even tells you the tire’s temperature further protecting you against tire blowout.
After all, a tiny difference in PSI can make a significant impact on the weight amount your tires can responsibly carry. For instance, if your tires are 10PSI less than the recommended pressure level, it reduces maximum weight by 25%.
So, before every trip, check your tires with tires with gauge. It’s in your best interest.
Now, that you know all about the best RV air compressor on the market, it’s time you go out and get yourself one. There’s no reason your trip has to suffer because your tires weren’t inflated to the proper level with the existence of products like these.
Therefore, do both you and your family a favor and invest in one of these incredible products. I promise you won’t regret it when you’re having the fun and stress-free trip that you envisioned.
