Buying Guide to Choose the best portable compressor for RV

So if you have any confusion or if you are a beginner about air compress terms then we have described everything here so that you can easily choose the best compressor or inflator according to your need.

PSI and CFM

PSI stands for Pounds Per Square Inch it is the air pressure that an air compressor can deliver. So to know how much PSI rating is required for your RV? First, you need to know the required PSI for your RV tires, then select the compressor that can deliver more than the required PSI. For eg:- If you need 45 PSI for your tire then you need a compressor that can provide more than 45 PSI of air pressure.

CFM Stands for Cubic Feet Per Minute it’s an airflow that a compressor can provide at a given pressure level. If a compressor has a high CFM rating then it can provide more air and as a result, your RV’s tire will fill up quickly.

Duty Cycle

The duty cycle is represented by the time which an air compressor can run continuously run upon one hour multiplied by 100.

So if a compressor is rated for 33% of the duty cycle then within one hour it can run continuously for only 20 minutes. If a compressor has a 50% duty cycle then a compressor can run continuously for 30 minutes.

So The higher the duty cycle, the better.

Length of Hose

A large vehicle has 4 or more wheels but not all the wheels are present in the same place. That’s why you need a long air hose to easily inflate all the tires of your vehicle. So that you can easily inflate all your tires without any hassle.

Length of Cord and Type

Generally, Inflators or 12V air compressors have two types of electric connection one is through battery alligator clip and another one is through cigarette lighter port so make sure that which connection is available on your compressor. And also make sure you get a good length of the power cord.

Other Inflating Equipment

With these small air compressors or inflators, you also get much other essential equipment. Which makes it very easy to inflate. So during your buying journey make sure that the multiple inflation tips, pressure gauges, canary bag, Battery alligator clip, air hose, and other RV attachments are available.

Voltage Requirement

Large Air compressors required voltage ranges between 120V or 240V but the small air compressor required voltage ranges from 12V and 24V. 

But in RVs or any vehicles have 12V of DC power supply so 12V of air compressors are more convenient to use on RVs.

Weight

Lightweight air compressors are easier to carry and more convenient to use. And generally, 12v air compressors are light in weight which makes them easy to use during road trips.

  1. VIAIR is a wonderful high-pressure tire air compressor/inflator. I used my digital handle/gauge with male quick connect rather than the supplied analog. Once plugged in and turned on, it automatically activates and off to take care of high 125150 pressure. This makes it easy to maneuver around each tire without manually changing the unit or running it continuously. Air my fat 65-80 LT tires at about 1 psi every few seconds. I aired 4 large LT tires and filled 4 trailer tires in an exceedingly mostly continuous run of about 10 minutes. it’s warm enough but it doesn’t break because of the warmth. you would like to attach it to the battery thanks to the high current draw. The case is generously sized and extra items are easily inserted.
