FAQs about Best Air Compressor for RV Tires

How much of pressure (psi) does it need?

The pressure discharged by the compressor must exceed the psi requirement of all pneumatic tools or other machines requiring power.

(Psi- pounds per square inch)

How much air flow (cfm) does it need?

Cfm is the measure of airflow that the portable air compressor can create. You can sate Cfm in two different forms, i.e. piston displacement (PD) or actual cubic feet per minute (acfm). Acfm reflects the real amount of usable compressed air.

Choose a compressor that exceeds the psi and cfm requirements of your equipment so that you are not underpowered. You attain the best results when you purchase an air compressor with 1-1/2 times more cfm than your equipment requirements.

(Cfm-cubic feet per minute)

How much horsepower does it need?

The horsepower is directly proportional to the cubic feet per minute rating of the air compressor. The higher the horsepower, the higher air (cfm) compressor can deliver. However, do not rely solely on the horsepower when selecting the best portable air compressor.

Which size of the tank does it need?

A portable air compressor has a tank that provides a reserve of air to meet peak flow and pressure demands. The larger the tank, the more reserve is available. Tanks can either be vertical or horizontal.

What supply of electricity is available?

The power supply is an essential factor that you should consider when buying an air compressor. Where a three-phase and single-phase compressors are available, the best option is a three-phase air compressor. It produces more efficient compressed air than the single-phase equivalent units.

Single-phase compressors of up to 2.5 hp can operate from a 240v 13 amp power supply, except the new 3.0 hp low current models. 3.0 hp and higher must run from a 240v 30 amps supply. When possible, choose large air compressors that you require to allow for expansion.
