RV Air Compressor Basics

Without a trailer air compressor, your travel plans might get derailed. There is no way you would want a flat tire to ruin your trip. When you are in a remote place for months, you better have all the right tools, including an RV tire pump.

What Is It?

In simple words, an air compressor for RV is a tool that inflates the tires. Other than tires, it can pump up almost any inflatable, including footballs, kayaks, paddleboards, and more.

The main function of an air compressor is to monitor and maintain the tire pressure. When you have it, there is no need to drive to the nearby gas station when one of the tires gives up in the middle of the journey.

How Does It Work?

An RV tire inflator compressor has a tank that is filled up with air when you connect the compressor with a power source. With the help of a piston and cylinder, a motor pushes the air to the tank. Inside the tank, the air gets pressurized to the level of your choosing. This pressurized air then passes from the tank to the tires of the RV through an air hose.

Use the compressor when the tires are cold to get the correct tire pressure reading. The pressure increases when the tires run for a while because of friction with the road and hot air inside them.

Each tire has a maximum inflation pressure recommended by the manufacturer. Don’t ever inflate the tires beyond that rating. Overinflation affects the traction of the tires, shortening their life or causing them to blow out.

Benefits of RV Air Compressors

The best RV air compressor would provide multiple benefits that will be worth its price. Following are a few advantages that you can expect from a quality compressor:

Versatile use

A compressor’s main function is to inflate tires. However, a good one would have multiple nozzles compatible with various inflatable items, like bike tubes, pull toys, beach balls, different tire types, and more.

Convenience

Using the best portable air compressor for RV tires means you can travel anywhere without fearing to deal with flat tires. Just attach it to the vehicle’s battery or cigarette lighter socket and fill up the tires.

Automatic functions

The best tire inflator for RV should relieve the user from any guesswork. The functions should be automatic, so all a user needs to do is setting the air pressure, attaching the hose to the tire, and plugging the pump into a power outlet. When the tire is inflated to the desired pressure, the machine should shut off automatically.

Long-lasting

The best RV tire inflator should last for several years. The use of stainless steel material and high-quality components, such as insulated rubber valves, ensure the tool’s longevity.


Types of Air Compressor for RV Tires

The air compressor for RV tires can be of several types. However, the portable ones are mostly used in travel trailers.

Reciprocating Air Compressors

By using the principle of positive displacement compression, these machines increase the air pressure inside their built-in air tank. They accomplish the whole task with the help of a piston.

Rotary Screw Compressors

They too utilize the principle of positive displacement compression. However, they have two rotors for compressing the air and increasing its pressure.

Centrifugal Air Compressors

Employing the dynamic compression theory, these tools have a rotating impeller to transfer the energy to an air shaft. There are shaft seals and atmospheric vents that keep the spinning gear separate from the air tank.

Portable Compressor

As the name suggests, these pumps are portable in design. This is the most common and popular type because of its portability. Many RVers, campers, and seasonal travelers use them because they are easy to move around.

These compressors are available in various versions based on horsepower, PSI (pound per square inch), and CFM (cubic feet per minute). They are lighter than the traditional compressor type.

New to RV lifestyle. Love this little guy. Just attach to the tire, set the PSI, turn on and it will auto stop when the PSI is reached. Will say that u may have to play around with the connection point to properly activate the airflow. If the compressor vibrates a lot, u do not have a secure connection. There should be a steady hum without any vibration. It’s not required but I recommend a little break in between consecutive fills to prevent overheating. I noticed better subsequent fills worked better after a break. Note that this is a small compressor so it may take some time if your item needs a lot of air. Stores nicely.

Pros:

  • Reasonable price
  • Outstanding portability
  • Installation is child’s play

Check prices and reviews

Specifications:

  • Maximum Pressure: 150PSI
  • Flow Rate: 2.3CFM
  • Dimensions: 10.9 x 5.8 x 7.5 Inches
  • Weight: 10.7 Pounds

Why It’s An Editor’s Choice:

Engineered for recreational vehicles, Viair 40047 is held in high esteem by RVers that opt to use purpose-design products.

With a maximum pressure of 150PSI and a flow rate of 2.3CFM, 40047 could fully inflate typical tires of recreational vehicles in just a flash.

Moreover, as it comes with two 30-foot hoses for a total length of 60 feet, the Viair compressor is capable of supporting rigs of various lengths.

For casual RVing enthusiasts, Viair 40047 is undoubtedly the best air compressor for RV tires.

Interestingly, the compressor from Viair can be paired with 45-degree and 90-degree twist-on chucks so accessing hard-to-reach valve stems is a piece of cake.

The inflation gun of 40047 incorporates a gauge too, hence, it’s a simple matter to monitor the tire pressure.

Boasting an automatic shutoff function, Viair 40047 eliminates the need to turn off the compressor manually while switching between tires.

That is a big plus for RVers that happen to own rigs with multiple wheels.

Thanks to the low-profile build, 40047 of Viair only occupies little space and could be relocated at short notice.

Viair provides a carry bag to people that pick up its compressor as well so you don’t have to worry too much about exposure.

I have an RV with duallies on the rear and valve extenders. For the life of me, I could not get any air through the extenders using several varieties of so-called heavy duty tire inflators. I even tried a fifty pound air pump. Couldn’t fill at the gas station either. Only at the tire store. FINALLY, I found the Viair. It is very expensive but it is also a serious piece of equipment and it actually puts air into my tires using a convenient professional system and a screw on chuck which is far better than the clip-ons. You can calculate the pressure during the inflation process right from the hose without stopping to use a separate gauge constantly. It doesn’t vibrate all over the place like most of them. It is relatively quiet. OK, it is a little heavy and it doesn’t plug into the cigarette lighter, but easy to work with on my house batteries. Every RV person should have one of these. Seriously.

 Perfect inflator for RV use

Bought this to use specifically with the Roy Pow AC to DC Converter 180W (Max 200W) 12V15A Power Supply Adapter (also purchased on Amazon). The set allows me to inflate RV tires via 120v source or 12v source (I use my portable Kodiak Solar Generator for the 12v source). Volume of airflow for inflation is understandably low, but the PSI for inflating RV tires (80-100 psi) is what I was looking for in this unit. When I first received the unit I performed a “break in” for the pistons by running without being connected to a tire (no pressure resistance). I did the “on for 5 mins then off until cooled” cycle about five times. So far so good with absolutely no problems. Knock on wood. Fairly good price, quick delivery.

This little air pressure is a work horse for RV use! It fills quickly, recycles fast and has plenty of pressure to fill RV tires up to about 135 lbs without issue but remember, this is not 6 gallon pancake compressor. It’s lightweight, compact and the housing makes it ready to pack. If you need more, then her bigger compressor. It does not have any quick connect parts which I added to hook up the hose quickly. The little coiled air hose isn’t very tough and should be replaced with a better hose when you get the chance.

This compressor was purchased for one main purpose to maintain the tires in my RV properly inflated. It does a great job, it fits perfectly in a compartment on the side of my RV directly under a 115v outlet. So I can run it inside compartment no extension cord and it is so quiet because compartment absorbs sound like a sponge. I used a plug-in meter that monitors volts, amps, watts, hertz, watt hour and my RV is connected to my home via shore wire. Here are results: No load voltage 119.2, load voltage 110.6, watts varied from 1068 to 1100 as pressure increased, amps varied from 9.6 to 10.1 by pressure. I also have a 1200 watt inverter however I will need to upgrade to run compressor to a 2000 watt pure sine wave. I advise never to run compressor on a modified inverter the sine wave is almost square and it will ruin your compressor motor right quick. I am extremely happy with my compressor, perfect blend of size, power and prize.

How to Choose The Best RV Air Compressor

There are certain criteria to consider if you want to get the best air compressor for RV tire in the market.

Power Source

A pump can draw power from various sources. Compressors compatible with 12V DC are the most common and they have to be connected to a vehicle’s 12V power port.

Some models can get their power from a traditional electrical outlet, which is 110V AC. There are some wireless models that have a built-in lead-acid or lithium-ion battery as the power source.

The most convenient ones are the multi-powered devices that are compatible with various types of power sources. They are most likely to have integrated batteries too for cordless operation.

PSI and CFM

PSI refers to the working pressure while CFM is the measurement of the air discharge speed. Both of these factors are highly important in determining the functionality of the best RV air compressor.

Depending on the model of the pump, PSI could range between 0 and 150 and this PSI also regulates the CFM. A compressor with a low PSI will take longer than a high-PSI device to inflate a tire.

Features: Gauge, Cylinder, and Power Cord

An air compressor normally has two pressure gauges that do the job of measuring the PSI. The cylinder or tank size is important because this is where the air gets stored. Its size indicates the volume of air pressure the pump is capable of storing.

Also, the power cord length is another feature to focus on because its length determines how far you can take the tool from the power outlet. Usually, a power cord could be between 4 and 30 inches.

Weight and Size

The weight and size of an RV air compressor give an idea about if it would be portable or not. For easier transportation, the device should be below 40 pounds. If the hose length is short, you may need to move the compressor around to inflate all RV tires. In that case, you must want to avoid a heavy unit.

FAQs About Compressors For RV Tires

If you are still confused about choosing the best RV air compressor, the answers to these questions will further help clear your doubts:

How to inflate RV tires with an air compressor?

If you need to inflate a tire, let it cool down properly. Take off the cap sealing the valve of the tire before putting the pressure gauge’s plug into that valve. Now, press down the gauge and keep applying pressure until the hissing sound of air escaping stops.

The next step involves plugging the compressor into the power socket in your car. Connect the hose’s nozzle to the tire’s valve. Switch the machine on and let the pressurized air pass from its tank to the tire.
When the tire is inflated to the desired PSI, turn off the compressor, disconnect the nozzle, and seal the valve off with the cap.

What size air compressor do I need to inflate RV tires?

The size actually does not matter when it comes to air compressors. The thing you need to make sure of is whether its PSI rating is enough for your RV tires. For example, if your RV tires require 50 PSI, the compressor needs to be rated more.

How long does an RV air compressor last?

Even the best RV air compressor will wear out over time, just like all machinery and tools. It can last around 4 to 8 years but the lifespan also depends on maintenance and storage. Regular cleaning and storing in a dry place save the device from unwanted rust and corrosion.

 Should RV tires be inflated to max PSI?

No. The “maximum cold pressure” should be imprinted on a tire’s sidewall. You should never inflate the tire at or over that PSI.

What PSI should RV tires be?

Checking the owner’s manual is the best way to find the correct PSI for the tires. However, the tires of recreational vehicles generally need 100 PSI or slightly more.

  1. Thanks for the great info!

  2. I even thought that I already found the lightest portable air compressor on the market when I bought a 6-pound model. However, VIAIR 00088 is even lighter with its 4.5-pound weight. Despite its reasonably small construction, this compact air compressor can pump air to many vehicles. It can provide air to tires of up to 33 inches in one operation.

  3. I use VIAIR to air up LT and RV tires to 80psi while on road trips. Works great, is fast and the combined length of the power cord and two air hoses allow me to tire of a 35 foot fifth wheel with no problems. Compressor shuts off automatically, allowing you to air tires a long distance from it without having to manually cut it off. This is the best compressor I have owned. It is pricey, but I firmly believe you get what you pay for.
