Air Compressor Buying Guide: Top 10 Considerations When Choosing A Commercial Air Compressor

Commercial air compressors are used in many different kinds of facilities and workshops. Their uses help people get work done efficiently and productively, so getting a high-quality air compressor is key if you want to maximise your facility’s work output. 

But, finding a good fit for your place can be tricky, especially if you don’t know what to look for. How do you know which kind of air compressor to pick?

In this article, we will cover a few things that you should always consider before you select your new air compressor, so keep reading to learn more helpful information.

There are quite a few different kinds of air compressors. Naturally, certain types are better suited for certain workplaces, and choosing the wrong kind could hinder your productivity. 

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.
