Consider the following things before you purchase anything:

1. What Compressor size do I need?

The very first step of choosing a air compressor is to understand what size compressor you need. The correct size of a compressor depends on the task means to perform. Pick one is too small and it won&#;t get it job done. Choose one it is too large, and it will waste energy and could lead mechanical problems. Correctly sizing your compressor requires real data about your needs, not guesswork. Whether you&#;re upgrading your current compressor or designing a new system, ask a compressed air sales professional to conduct an air system audit to measure your actual demand.

If you&#;re planning for future capacity, keep in mind that a compressor should be sized to address actual demand. Instead of anticipating potential future demand by oversizing today, add a compressor when the time comes to provide flexibility and redundancy as your operation expands. Also keep in mind that process improvements often reduce air demand; you may be able to expand your operation without expanding air production.

2. What type of compressor do I need?

The next thing to do is to decide on the type of compressor you need for your application.  

There are two main types of compressors, piston compressor and rotary screw compressor. Piston compressor which are sometimes also called reciprocating air compressors, are the most economical and least expensive air compressors available. Rotary screw compressors are often the ideal choice for operations that require a constant compressed air supply.

3. Does air quality matter? Oil-Free Or Oil-Lubricated?

Generally, there are two basic categories of air compressors; oil-free or oil-lubricated. Oil-free air compressors don&#;t use oil and can help you ensure that your air quality is great. These are ideal for facilities where air quality is extremely important. On the other hand, oil-lubricated air compressors use oil to lubricate their parts. These machines are incredibly energy-efficient. Take some time to reflect on which type you prefer more. 

 To not overcomplicate the answer, your choice should be based on the application and process that the compressed air will be utilized in.

4. Understand the pressure and flow?

Compressed air flow is typically measured in cubic meter per minute (M3/min). Compressed air pressure is typically measured in pounds per square inch (Kpa) or barg. Think of flow as the ability to perform a process within an acceptable time frame, and pressure as the ability to support multiple processes at once.

5. What&#;s The Duty Cycle?

An air compressor&#;s duty cycle refers to how often the machine will run. Different models will have different cycles, which could affect your facility&#;s work.

6. How Much Space Will It Take?

Smartly using your available space is crucial if you want to stay organised and productive. Think about how much space you have allotted for commercial air compressors and try to find an air compressor that will be suitable for your worksite.

7. How Will It Be Installed?

Think about how your air compressor will be installed once you&#;ve purchased it. Will you install and set it up yourself, or will you hire someone else to do it? You should also consider how your product will be delivered and, if you are replacing an old one, how you will remove your old air compressor.

8. How Will It Be Maintained?

Always figure out the best way to maintain your new air compressor before you order it. Factor in the long-term maintenance cost if you are working on a tight budget. Good air compressors work well and aren&#;t a pain to maintain, so knowing how to take care of your air compressor before you have it is a good idea. 

After you purchase and receive your air compressor, remember to maintain and check it routinely. Well-maintained air compressors are less likely to break down than neglected ones and will last longer.

9. Initial vs. Overall Cost

When considering an air compressor, a primary concern should be: &#;How can I get the most amount of compressed air for the lowest overall cost?&#; Many consumers may consider only a small fraction of the life-cycle cost &#; primarily the initial cost of the machine, not realizing they will likely spend more in electricity the first year to run the machine than the purchasing price. That&#;s why, when comparing compressors, it&#;s important you examine all aspects of the costs associated!

10. Not Sure Where To Begin?

Start by analyzing your air system&#;s life-cycle costs! You can analyze your usage and potential cost savings by conducting a no-contact compressed air energy assessment. Best of all - it causes no harm or downtime to check.

Finally, it&#;s absolutely essential that you only buy your new air compressor from a reliable seller. Purchasing important products from companies who don&#;t care about quality can land you in hot water. 

Good sellers will always value the quality of their products and the satisfaction of their clients. So, it&#;s vital that you always make sure you are buying from reputable and experienced companies.

Rotary screw air compressors are perfect for the following group of people and applications:

• Large garages and workshops with air tools
• People who require a lot of compressed air.
• Large or small production facilities or industries

But there are many situations where various businesses opt for rotary screw air compressors in places where reciprocating air compressors can work better. If any of the following applies to your projects, then you do not need a rotary screw air compressor:

• You need air compressors for hand tools.
• You do not need air continuously.
• You only need compressed air for home DIY work.
• You need compressed air for light construction works, such as powering nailers.

In the above cases, you can go for a reciprocating air compressor to get the work done in the best of ways.

Choosing the right capacity and pressure for a new rotary screw air compressor.

It is essential to consider the right air compressor that can supply enough amount of compressed air at the right pressure to power all your tools. Unfortunately, most people do not know their requirements and end up buying too big or too small air compressors.

So, this section will help you in that respect. If you opt to buy a rotary screw air compressor, it should be for the following reasons.

1. It is your first air compressor

Check your user manual and specification sheets of the pneumatic equipment. This part should tell you the right pressure at which your air tools operate and the capacity you need. The components that require the highest pressure will dictate the pressure requirement. You should also add 1.5 bar to the minimum pressure required to account for any pressure drop and load-unload differential of your rotary air compressor.

After that, you should add up the air consumption of all your air tools. This should be the capacity of your air compressor. It is essential to buy a bigger air compressor, but not too big. Rotary screw air compressors do not like standing still. You should keep in mind that some air tools come with average consumption rating while others state the maximum consumption rating.

2. It is a replacement for an old rotary air compressor.

You should check the capacity and pressure of your old rotary air compressor.If the old air compressor you had was adequate, you should buy a new air compressor of the same pressure and capacity. You should take a moment to decide whether it is the right choice to get a slightly bigger air compressor to account for future consumptions.

3. You have a reciprocating air compressor and need more capacity (cfm).

You should check the pressure of the current air compressor. Ignore the maximum pressure rating of a reciprocating air compressor since it is often higher than what is needed to operate your air tools.

If you want a replacement for your air compressor, you should check the capacity of the current air compressor. Now you understand that you should buy a slightly bigger air compressor than the current one. How big? This one depends on the type of air tool and equipment you added to the business that made you opt to get another air compressor. You should also keep in mind that your business can expand in the future.

If you want a replacement to your old air compressor, you should keep in mind that a rotary screw air compressor does not like standing still as it will likely be old and rusty. In this case, you have to ensure that your rotary air compressor is the primary compressor, while your reciprocating air compressor becomes the secondary compressor. Rotary screw air compressors are the most energy-efficient.

4. You have a rotary screw air compressor and need more capacity.

Most of the time, people tend to buy the same type of air compressor as the one they already have. This is an excellent idea because it allows you to use the two air compressors side by side or use one as a backup for the other. Another great idea is buying a slightly bigger air compressor and use the old one as an emergency back up option.
