Air Compressor Cfm Rating

In this article we re going to help you better understand how many cfm you need to run your air tools.

Air compressor cfm rating.

I have a 600 cfm compressor in my garage that uses only 1 3 hp. Icfm inlet cfm rating is used to measure air flow in cfm ft 3 min as it enters the air compressor intake. It is a unit of measurement of a compressor s capability. It plays the most important role during the evaluation of a compressor.

To begin with despite being a single stage compressor its cfm rating is as good as the 2 stage ones. The cfm rating refers to the volume of air that the compressor can supply. This is a gas powered air compressor with a one gallon tank capacity that is also oil free. As you lower the psi output cfm increases.

The cfm value changes as psi changes. It is quiet not the quietest air compressor from the options available at the moment on the air compressor market but still ranges at 71 decibels which is a good noise level for an air compressor in a quieter hobby workspace for example. Compressors with higher cfm ratings provide more air which makes them more practical for larger jobs. This is the actual volume flow rate in the pipework after the compressor.

Your tools cfm requirements give you an idea of what you need your air compressor to do but it s not enough to simply match the air tool s rating and the compressor s rating 1 1. The cfm ratings are psi specific. By itself the cfm rating tells an incomplete story about an air compressor. It s a fan delivering 0 1 psi rules of thumb.

The higher the cfm rating of a compressor is the better are they for heavy jobs. Cubic feet per minute or cfm is the volume of air that a compressor delivers to an air tool. Fad free air delivery f a d is the. Acfm actual cfm rating is used to measure air flow in cfm at some reference point at local conditions.

California air tools lfc air compressor. Cfm ratings are meaningless without an associated delivery pressure. For example a small muffin fan in a computer can deliver 200 cfm. Compressor manufacturers rate storage tank size in gallons.

A good single stage compressor per true hp input will deliver about 4 true cfm at 100 psig. A compressor can deliver a specified cfm at 45 psi and a different cfm at 90 psi. A compressor with a higher cfm rating can deliver more air and is better suited for heavier applications such as operating air wrenches and framing nail guns. The improvements made to the new model certainly puts it in line to achieve the same accolades in 2019.

While it can rise to a maximum of 135 psi it scores quite high with its delivery of 18 1 cfm of air volume at 90 psi. The vast majority of air tools require psi of 40 or 90 to get the job done. Pounds per square inch is the measure of air force delivered by the air compressors.
