As a result, an air compressor is a cost-efficient way of completing your maintenance, construction and manufacturing faster.

So you need to upgrade or are looking to build a facility, you’ll need to know which type of air compressor you will need?

1. Determine the purpose of buying an air compressor. Where and how will you use it?

2. Determine your power requirements.

Once you’ve identified the above requirements, you can consider these factors:

CFM Requirement

CFM or cubic feet per minute determines the speed of how much air an air compressor can supply. This measurement is the number one factor to consider when buying a compressor. Testing the air compressors at 90 PSI-AN average setting is a must for manufacturers; this is to ensure that you are comparing apples to apples. Compressors are tested within 0.6 to 2.8 CFM.

Tank Size

Tank capacity tends to range from 1 to 6 gallons. The amount of air a tank can hold can seriously affect the overall performance of a compressor. Remember, a large tank should not replace an adequate CFM.

Oil-free vs. Oil Compressor

It is important also to set aside time for further research as to whether you would go for oil-free compressors: these are typically low maintenance and contaminant-free, or standard compressors: these can produce a larger output and can run more quietly.

Professional vs. Semi-professional vs. Domestic

Your purpose for buying an air compressor is important to determine your power requirements and the limit of your warranties. Furthermore, knowing the answer to these questions will help you identify the right compressor for your application – whether it is professional, semi-professional, or for domestic use. Industrial compressors can output vastly stronger performance than compressors for domestic use.

Portable vs Stationary Compressors

Portable compressors provide freedom and flexibility to have compressed air anywhere. These compressors are usually used in activities such as inflating sports equipment or air mattresses.

Stationary compressors, on the other hand, are typically larger and can offer more power than a portable compressor; this is because of the increased tank size.

These are some of the basic factors to consider when choosing an air compressor. Furthermore, the power source and expertise can also affect your decision. Whether you opt for an electric motor or a gas engine, always keep in mind to find a compressor that can maintain CFMs at desired PSI.
