How To Buy An Air Compressor: A Step-by-step Guide
What To Know
- To determine the CFM you need, add up the CFM requirements of all the tools and equipment you will be using with the compressor.
- Once you know the size of air compressor you need, you can start to choose the features that are important to you.
- Reciprocating compressors use a piston to compress air in a cylinder, while rotary screw compressors use a screw to compress air in a chamber.
Are you in the market for a new air compressor? If so, you’re in the right place. This comprehensive guide will walk you through everything you need to know about how to buy air compressor, from understanding the different types of compressors to choosing the right size and features for your needs.
Types of Air Compressors
There are three main types of air compressors:
- Reciprocating compressors are the most common type of air compressor. They use a piston to compress air in a cylinder.
- Rotary screw compressors use a screw to compress air in a chamber. They are more efficient than reciprocating compressors, but they are also more expensive.
- Centrifugal compressors use a centrifugal force to compress air. They are the most efficient type of air compressor, but they are also the most expensive.
Choosing the Right Size Air Compressor
The size of air compressor you need will depend on the CFM (cubic feet per minute) of air you need. CFM is a measure of the volume of air that the compressor can deliver per minute. To determine the CFM you need, add up the CFM requirements of all the tools and equipment you will be using with the compressor.
Choosing the Right Features
Once you know the size of air compressor you need, you can start to choose the features that are important to you. Some of the most common features include:
- Automatic start/stop – This feature allows the compressor to automatically start and stop when the air pressure drops below or rises above a certain level.
- Pressure regulator – This feature allows you to adjust the output pressure of the compressor.
- Oil-free – Oil-free compressors do not require oil to lubricate the moving parts. This makes them ideal for use in applications where oil contamination is a concern.
- Portable – Portable compressors are designed to be easy to move around. They are ideal for use in applications where the compressor needs to be moved frequently.
Installing Your Air Compressor
Once you have chosen an air compressor, you will need to install it. The installation process will vary depending on the type of compressor you have purchased. However, there are some general steps that you should follow:
1. Choose a location for the compressor that is well-ventilated and has plenty of space around it.
2. Connect the compressor to a power source.
3. Connect the compressor to an air tank.
4. Test the compressor to make sure that it is working properly.
Maintaining Your Air Compressor
Once you have installed your air compressor, you will need to maintain it regularly to keep it running in top condition. Some of the most important maintenance tasks include:
- Checking the oil level (if applicable)
- Changing the air filter
- Draining the condensate from the air tank
- Inspecting the compressor for any leaks or damage
Troubleshooting Air Compressor Problems
If you are experiencing problems with your air compressor, there are a few things you can do to troubleshoot the problem:
- Check the power source to make sure that the compressor is getting power.
- Check the air filter to make sure that it is not clogged.
- Drain the condensate from the air tank.
- Inspect the compressor for any leaks or damage.
If you are unable to troubleshoot the problem yourself, you should contact a qualified technician.
Key Points: Making the Right Choice
Buying an air compressor is a big decision. By following the tips in this guide, you can make sure that you choose the right compressor for your needs. With proper care and maintenance, your air compressor will provide you with years of reliable service.
Frequently Asked Questions
Q: What is the difference between a reciprocating compressor and a rotary screw compressor?
