Air Compressors are the most fundamental machines in air-run applications. Compressors are often regarded as the power-generators of air-tools because they run using the high-pressure air supplied by the compressor. Compressors have evolved into reliable machines in numerous fields and come in wide range varieties with different types and sizes.

Before choosing a compressor it is important to understand whether the compressor ratings are suitable for the application. Purchasing a compressor that is too small for the application will waste time and purchasing a huge one with a higher rating will waste resources.

Have a look at a few questions which you need to answer while making a choice to buy air compressors

What is the maximum operating pressure required for the application?

An answer to this question will determine whether you would need a single stage or two stage compressor. A two stage compressor delivers greater pressure than a Single stage machine. If you require higher pressure (>120 psi), a two stage compressor will be ideal.

What is the maximum CFM requirement?

CFM-Cubic ...
... Foot per minute is important to determine the air velocity required in operating an air-tool, each air tool will have a specific CFM number.

To make an answer add up the CFM number of all the tools used at the same time, add another 30%with the calculated CFM number, that’s your CFM. This will be ideal for finding out your CFM requirement and your compressor.

What type of drive system is needed?

Compressors can be operated by an electrical drive or a gasoline-powered drive. If it is possible to get consistent electricity then electrically driven compressor is the perfect choice. In the case of in-consistent power availability, a gasoline engine will be the unanimous choice.

Gasoline engines offer the best in portability and work area flexibility.

Does the machine need to be portable?

It is important to determine whether the machine needs to be moved from one spot to another, then it’s obvious that you need to purchase a portable machine. The arrangements for portability will vary with increase in size and weight of the machine.

What is the required size of the tank?

The size of the compressor tank should be determined based on the type of usage. A smaller tank is usually preferred for air usage in quick bursts. In order to sustain longer periods of usage, a large sized tank will be necessary.

Whatever compressor you may need, it is important to consult an expert in dealing with compressor and air-tools to ensure a good and ideal purchase.
