How to use it?

how-to-use-and-select-air-compressorUsing an air compressor is not that difficult. Of course if you have never read the air compressor reviews you probably are clueless as to how one works. So, sometimes you go to prefer guide manual books. That should be long for you to read and it will waste your time on unnecessary things on reading it.


  • Attach the hose to the compressor. Then attach the accessory that you will be using such as blow gun, pressure gage, tire inflator or any special attachment that you wish to use.
  • Plug the air compressor into an electrical outlet and allow the compressor to pump air into the tank. After the compressor has reached its preset pressure it will automatically shut off and will be ready to use.
  • Squeeze the trigger to allow the compressed air to come out and into the tire or into the item that you need the compressed air for. Hold the trigger down and allow the air to steadily go into where the air is needed.
  • Recharge the air compressor by allowing the compressor to sit without use. Your compressor will make a noise when it is charging. As stated before in step two the compressor will automatically shut off when it has reached its preset limit.
  • Repeat this procedure until you are done using the air compressor. There is no limit to how many times in a day that you can recharge and use your air compressor.

These steps are enough for you as amateur for the air compressor. As a starting just do as we stated above, it will help to work on your compressor.

How to Select an Air Compressor?

Your air compressor is a source of power. Whether you’re a weekend hobbyist or a business owner, you need the right size of air compressor to power your air tools properly and efficiently. Selecting the right air compressor to meet your needs is simple, if you follow these steps.

Materials Required

  • The manufacturer’s CFM requirement for all of your air tools

Steps to Follow

  • Pneumatic air tools require a volume of compressed air (expressed as cubic feet per minute, or CFM) at a specific pressure (expressed as pound-force per square inch gauge, or psig). The efficiency of a compressor is determined by its CFM and psig ratings, not necessarily its horsepower. Therefore, you can ignore the horsepower rating when sizing and selecting a compressor.
  • Gather all of your pneumatic tools together. Write down the required CFM to operate each tool, as specified by the manufacturer. If you can’t find this information, you can look online for a chart of standard requirements for common pneumatic tools.
  • Add together the CFM requirements of all of the pneumatic tools you plan to run at the same time. Increase this number by 25% to allow for additional tools, future growth, and eventual air system leaks.
  • Determine the maximum pressure (psig) needed to run the air tools. You do not need to add the psig values together like you did the CFM requirements; simply use the value of the tool that requires the greatest amount of pressure.
  • Be sure the motor characteristics of the compressor are compatible: Is your electrical supply single-phase or three-phase? What is the voltage? Residential and commercial buildings usually have single-phase, 115 volt, 60-cycle power, while industrial buildings often have a three-phase power supply.
  • Small compressors should be used with an air receiver, or storage tank. The receiver stores compressed air and minimizes the loaded run time of the compressor. The air receiver should be at least 5 gallons per CFM for optimal results.
  • Take your CFM, maximum pressure, motor characteristics, and receiver size requirements to your local compressor dealer or home improvement center and compare features among brands. Keep the quality factor in mind; you will certainly get what you pay for with air compressors.


  • Most single-stage compressors have a maximum pressure rating of 135 psig. Most two-stage compressors have a maximum pressure rating of 175 psig.
  • More horsepower does not always mean a bigger and better compressor. This is because some compressors are rated at the peak horsepower of the motor and others are rated at the running horsepower of the motor.
