What does CFM mean in compressors?
CFM stands for cubic feet per minute and it tells you how fast the air compressor can push a specific volume of air. CFM ratings are usually rated at certain PSI ratings, i.e. 3 CFM at 90 PSI. But, you may also encounter some misleading advertising with CFM ratings too. For example, some compressors may be rated for 3 CFM at 90 PSI.
Why do air compressors draw more air?
The reason they draw more is because they need extra power. They need it to inflate large or high-pressure tires which are commonly found on most RVs, trailers, and motorhomes in general. You might also be able to tell how much an air compressor uses depending on how it’s labeled.
Can you use a 2HP compressor with a regular outlet?
That’s not something you can do with a regular house outlet. Therefore, a 2HP air compressor is more than enough as long as it can inflate high-pressure tires. One last thing to note is the CFM rating. CFM stands for cubic feet per minute and it tells you how fast the air compressor can push a specific volume of air.
Can a motorhome compressor be used on AC?
Not all compressors are used in motorhomes so some of them are designed to work with regular household outlets which run on alternating current (AC). But, there are also hybrid compressors. They can switch between AC and DC and can be used at home or on the road.
Do you have to keep the engine running to keep the compressor running?
Never forget to keep the engine running. The massive power draw of a running air compressor can quickly deplete the battery. If you keep the vehicle running, the battery can provide a consistent voltage to the compressor’s motor and it won’t fail you when you’re ready to hit the road again.
