Air compressors are machines that help users derive potential energy from fuels like diesel or petrol and store it into a tank in the form of cool compressed air. There are various applications for this compressed air such as powering tools such as nailers and inflating tires, inflatable pools, mattresses, etc.

Why is it important to get an air compressor for your RV?

Carrying an air compressor while traveling in an RV will help ensure that your tires are at proper pressure levels at all times. You can quickly fill them up to the right level before you leave home and this will help you stay safe throughout the journey. This means that you no longer have to make trips to the service station before you plan on hitting the road.

RV tires may blow out if they are filled enough or if they are overfilled. A portable air compressor will allow you to prevent that from happening. This is also quite useful if you get an unfortunate flat tire in the middle of nowhere.

Portable air compressors also have uses other than just filling up RV tires. They can also help you winterize your RV. Instead of putting antifreeze through the water lines of your RV, you can also opt for clearing the waterlines using a portable air compressor. This will help avoid any damage to your RV during winters and will help get your RV ready for the next trip on the road.

Before Buying Consider these features:-

  • Tank size

The tank size of an air compressor helps you determine how much air it can hold at a time. This affects the overall performance of the machine. Therefore, air compressors with bigger tanks can hold more air and they can help deliver longer run times.

However, bigger air tanks mean a bigger size which will be difficult to store in your RV. If you don’t need to use your air compressor for heavy-duty jobs then we suggest you get a smaller air compressor with a small air tank because you don’t need a lot of compressed air anyways. It will be smaller in size and hence, it will be easier to store and carry around in your RV.

  • CFM and PSI

PSI and CFM of an air compressor are two other important features that help determine the operating power of this unit. PSI helps measure air pressure while CFM is the measure of the airflow rate of the unit.

The PSI rating of a unit tells you much air pressure it can deliver and you can just match it with the air pressure required by your tires to ensure that it is enough. On the other hand, a higher CFM helps ensure that you will be able to complete your job quickly.

  • Noise levels

Air compressors can be a little noisy because you are working with pressurized air which can surely create a lot of noise. If you plan on using the unit indoors, make sure you get one with low noise levels something around 60 decibels or so.

  • Cord length

While working with an air compressor, there will be two kinds of cords that you have to deal with. If your air compressor is not battery operated then you will have to deal with a power cord that will help power the unit. Along with that, all air compressors come with an air hose.

It is better to go for an air compressor that comes with a long air hose as well as a long power cord. This will allow you to move around more and will expand the working diameter for your job.

  • Weight

When it comes to the best air compressors for RV tires, the weight of the air compressor is a very important factor to consider. You will have to move around the air compressor a lot so make sure you get one that does not weigh too much because otherwise, it is going to be too much of a hassle.

  • Price

Finally, make sure you consider the price of similar models before you decide on one. Don’t buy a very cheap product because otherwise, you’ll have to frequently change your air compressor because it will be of cheap quality. However, don’t overspend either, and make sure you set a budget before you begin hunting for the right product.
