Viair 40047 400P-RV

Viair 40047 400P-RV Automatic Portable Compressor Kit

While many of the models for inflating tires on our list can be used for RVs, few of them are made with the explicit intention of doing so. The Viair 400P-RV on the other hand is made exactly for that and comes top as our best RV air compressor

This model comes with two different chucks, a standard 90 degree twist-on chuck as well as one designed especially for use with rear dual wheels with a 45-degree extended reach.

Even better, it features one of the most significant airflows on our list at 2.3 CFM, which can inflate most RV tires in under 30 seconds. There are no concerns with this air compressor reaching the back wheels of your RV either as it comes with an air hose and extension that can reach 60 feet.

Bottom Line: With one of the most powerful motors, longest hoses, and specific coupling attachments made for RVs, this compressor kit comes out on top as our best motorhome air compressor.

Best RV Air Compressor: Keep Your Tires Inflated Without the Hassle

Whether you seldom get on the road with your RV or live it as a way of life, at some point you’ll need to do some general maintenance. One of the more common maintenance issues you’ll need to handle is keeping your tires inflated so as to avoid a flat tire.

You can always go to a gas station or other similar spot to reinflate your RV’s tires, but these locations are not always the easiest to get in or out of. An easier and often cheaper alternative, in the long run, is to buy a good RV air compressor.

That is why we put together a list of the nine best RV air compressors, outlining who they are most suited for. We also provide a thorough buyer’s guide, so you know what features are most important to look for in the RV air compressor market and which are hot air.

Things to Consider When Buying an RV Air Compressor

CFM & PSI Rating

The first spec is CFM, which stands for cubic feet per minute and rates the compressed airflow of the compressor. PSI stands for pressure per square inch and determines the maximum pressure of compressed air that a unit can provide.

The CFM matters as this will ultimately determine how quickly a compressor will inflate RV tires. It is essential to note the CFM of a compressor decreases as the PSI of a tire increases, so the CFM given is for 0 PSI.

These two specs are bandied about to sell you on a particular model, but only one of them is all that important. The maximum PSI rating of the unit shouldn’t matter since tires rarely require even 50 PSI, let alone the 100 to 150 maximum PSI rating often advertised.

Cables and Hoses

Since RVs tend to be large vehicles or have towing loads, cable and air hose length will restrict which compressors are suitable for different RVs. This matters less if you have numerous 12V attachments, but compressors that use 12V outlets are more limited.

Cables and air hoses are one of the more essential parts of an air compressor for use with an RV, as bad ones can make the model almost unusable. In fairness, while there is something to be said of the durability of the hose, length is the greater deciding factor.

Power Source

An RV tire air compressor can draw power directly from a 12V RV battery, or it can connect to a 12V outlet in your RV. The dash 12V outlet uses your RV’s fuses to moderate the power, which can limit the compressor’s power draw.

As such, compressors that draw directly from a 12V car battery can provide a bit more power to the motor than those that draw from a dash 12V outlet.

While the ability to draw power from a 12V outlet on your dash might seem convenient, it is only really applicable to smaller traditional vehicles than for RVs. With an often limited power cord length, a unit connected to a dash 12V outlet might not be able to reach your RV’s back tires.

Chuck Design

You generally want to lean more towards an air chuck that either twists or locks on, so you don’t have to press and hold the chuck into the tire valve the entire time. Another convenient type of chuck to have is the inflation gun, though these are less convenient when used with compressors that have a lower flow rate.

The chuck design may not determine how effective your unit is at inflating RV tires, but it can make a significant impact on how easy it is.

Portability and Weight

In terms of general portability, a handle always helps move the compressor around more easily. Some compressors feature perforated handles to ensure the handle doesn’t get hot while the unit is in use.

Depending on the type of RV you have, as well as when and where you reinflate its tires, the portability of your compressor can be more critical. If you need to inflate tires in an emergency, a smaller, more portable RV air compressor comes in handy.

On the other hand, if you have a compressor to run regular maintenance on your RV, the power from a more substantial, heavier model is a good trade-off. However, size and weight are not a great measure of how powerful the unit is.

Noise

All air compressors make a fair amount of noise, but there can be a vast difference in the volume from one model to the next. That said, the noise level is often tied to the power of the motor with more powerful compressors making more noise.

Smaller, less powerful options might be quieter, but they also have greater limitations on which tires they can inflate. Regardless of the volume, it is a good idea to get some form of hearing protection when using an air compressor for an extended period.

When you need a reasonably capable air compressor but don’t want to pay an arm and a leg, this TIREWELL model is a decent option. It only requires a 15A power draw so you shouldn’t have any concerns that this Tirewell RV air compressor will blow any of your vehicle’s fuses.

While not spectacular, the 1.24 CFM flow rate is at least average and a fairly substantial amount for the cost. As an added convenience, the TIREWELL comes equipped with a built-in LED light to make connecting the screw-on connector much easier at night.

While not the lightest we reviewed, this model is just over 5 lbs and more portable than many other comparable products we found. The direct-drive motor is housed in a steel chassis protecting it from breakage.

Be forewarned that the TIREWELL overheats more than some and can fail if you push it beyond its design.

    • Less expensive model

Aside from the excellent flow rate, the GSPSCN is also one of the more portable air compressors we reviewed, sitting at just over 7 lbs and with a convenient handle. The built-in LED light also makes using this RV tire inflator compressor much more manageable in the dark.

The GSPSCN sports a steel direct-drive motor able to handle average tire sizes, though it may not be suitable for larger RV tires. Still, the 25A power draw helps ensure that you do not have to worry about the motor breaking down. You can power it up using the battery clamps with your RV battery or alternatively plug straight into your cigarette lighter.

Keep in mind, the top exterior of this GSPSCN model is made out of plastic, not metal like the main chassis.

The AirLift 25856 onboard air compressor is installed on your towing vehicle and offers incredible reliability and convenient air suspension. This model comes with dual-path controls so you can inflate multiple airlines of your suspension system at once.

Even better, this model comes with a dash gauge that tells you the PSI rating of both air suspension springs simultaneously. To make things even easier, the gauge also comes with push-button controls to allow you to adjust the springs’ air pressure individually or together.

SuperFlow MV-9012

Best CFM

No products found.

When reinflating your RV’s tires waiting on a slow air compressor or worse waiting between duty cycles can be torture. That is why the SuperFlow MV-9012 tops our list with the most significant flow rate we came across at 3.71 cubic feet per minute.

Of course, a high flow rate is only as good as the motor pushing it, but the SuperFlow has you covered there too with a 45A direct-drive motor. On top of that, this air compressor is the only model on our list that comes with an air tank and sits at a solid 1.5 gal.

Considering how robust the SuperFlow is it follows that this unit has one of the more durable bodies on our list too. That said, you need to make sure that you can handle the massive power draw, and it is not the easiest to move around.

  • PROs

    • Puts out 3.71 cubic feet per minute
    • Has a durable chassis
    • More powerful than some
    • Has a 1.5 gal tank

Not everyone has a large Class A or even medium-sized Class C RV motorhome and so don’t need to spend the same kind of money on an air compressor unit. Step in the AstroAI which whilst more affordable also still has decent specs.

For example, while not the top-rated on our list, the 1.24 CFM flow rate is still respectable and on the average end of the scale. This unit also comes with a reliable gauge that measures air pressure more accurately than many of the other more budget models we came across.

On top of that, the 15A power draw means that you’ll have no concerns about blowing a fuse when connecting it to your 12V dash plug. Even better, the LCD backlit display and built-in LED light make using this unit at night a breeze.

Out of all the units we reviewed, few are as effortlessly portable as the Helteko with its sleek ABS chassis and a total weight that sits just above 2 ½ lbs. Even better, the Helteko comes with many features making it more convenient and comfortable to use.

For instance, like some other portable compressors, the Helteko comes with a bright LED light to make using it in the dark much easier. It also comes with a digital LCD display that simultaneously keeps track of the programmed tire pressure and current air pressure.

A stand-out feature of the Helteko portable tire inflator is its noise level, being the lowest we reviewed at under 50 dB.

    • Is a more portable product
    • Only a 10A power draw
    • Only puts out 50 dB of noise

The MasterFlow also features a brass coupler with three different adapter nozzles, but the Q Japan Nitto coupler is excellent for a wide variety of different tires.

VIAIR 45053 Silver Automatic Portable Compressor Kit (450P-RV)

Best for Class A RVs

VIAIR 450P-RV Silver Automatic Portable Compressor Kit (45053), 1 Pack

The most significant difference between this VIAIR air compressor and others on this list is the VIAIR 45053 will not overheat in the relatively short amount of time that some others do. Instead, this is the only product on our list that can run for an hour straight without having to be turned off to cool down.

Much like the other VIAIR model on our list, the 45053 also comes with a complete kit that includes the 60’ hose ideal for reaching the back tires of longer recreational vehicles. It also comes with the tire inflation gun, so you do not have to worry about a problematic tire chuck either.

This is also one of the more versatile RV air compressors on our list. Not only does it come with the additional 45-degree chuck to assist in inflating rear wheel tires, it also comes with various inflation tips for inflating other items such as air mattresses and pool toys.

While it does not have as high a flow rate as some of the shorter running models, it still holds its own with a rate of 1.8 CFM. On top of that, this air compressor doesn’t suffer from some of the durability issues that other products we came across had.

  • PROs

    • Comes with a complete kit
    • Puts out 1.8 CFM
    • Has a 60’ hose
    • Can run for 1 hr
