PSI? CFM? Horsepower? Choosing the Right Compressor
Horsepower?
PSI? CFM? There is a lot to consider when purchasing a new air compressor. It is important to understand what you actually need and how to
find out.
Choosing an air compressor solely based on horsepower could negatively impact overall operating expenses.
One of your primary concerns when choosing an air compressor should be โhow can I get the most amount of compressed air for the lowest
overall cost?โ Many consumers only consider the initial investment in the machine โ not realizing they will likely spend more in electricity
the first year to run the machine than the purchasing price.
So, the first step in choosing a compressor is determining the Cubic Feet per Minute or CFM demand your plant requires. CFM describes the
volume flow rate of compressed air. Improperly sizing your compressor can cost thousands of dollars in wasted electricity.
It is important to know in this situation, that more horsepower is not always better. It goes without saying that a higher HP machine uses
more electricity than a smaller one. For two air compressors with the same horsepower the CFM output could vary by as much as 25% between
companies and models.
In order to make an informed decision, it is critical to understand that all compressors are not designed equally and that you may be able
to use a smaller HP, more efficient compressor that produces the same amount of CFM, allowing you to keep profit in your pocket.
We have already stated that not all compressors are made equally, so how is a consumer to know CFM ratings, HP ratings and total package
energy usage? Well, a group of compressor manufacturers realized this dilemma and created a group called CAGI (the Compressed Air and Gas
Institute). Each compressed air manufacturer agreed to have their compressors independently tested and verified. Once verified, certified
data sheets, similar to a carโs window sticker when car shopping, are published publicly on each companyโs website with key information to
make your decision easier.
On each CAGI sheet, the amount of CFM the compressor produces at a given pressure, the maximum PSI (Pounds per Square Inch) that can be
produced, and the efficiency of the compressor in KW/100Cfm (similar to an automobileโs miles per gallon) rating can be found.
