How to pick the perfect air compressors for your needs?


Are you looking for a new air compressor? If so, it will be very important to select a suitable compressor according to your needs. There are a variety of different factors to consider, from PSI rating to tank size. In the blog post, we will guide you on how to choose the perfect compressor for your projects.


  1. What factors should you consider when making the decision?


Step 1. Types of compressor: Stationary or Portable?

Air compressors can be powered by electricity, gasoline, or diesel. Choose the one that suits your location and power needs. If you need to move the air compressor frequently, choose a portable one with wheels and a handle.

  2. b) Portable air compressor

Step 2. CFM measurement: Calculate the total CFM of the tools.

Tip: Please consider the tools you use. Determine which one requires the highest CFM at the highest PSI. Add about 30% to 50 % to the required CFM to find a compressor that meets the request.

For example: if the tool needs 3 CFM at 90 PSI, then we estimate to add 50%. Select the compressors that deliver at least 4.5 CFM at 90 PSI.


Step 3. Pressure (PSI): The pressure, measured in pounds per square inch (PSI), determines the power of the air compressor. Choose a compressor with enough PSI to handle your tools and tasks.


Step 4. Tank size: The size of the tank determines the amount of air that can be stored and the length of time you can use the tools before the compressor needs to recharge.


Step 5. Noise level: Air compressors can be loud, so if you plan to use it in a residential area, choose one with a low decibel rating.


Step 6. Horsepower: The horsepower rating of an air compressor can affect its performance. Choose an air compressor with sufficient horsepower to meet your needs.


Step 7. Price: Air compressors come in different price ranges, so consider your budget and the features you need before making a purchase.


Overall, it is important to consider your specific needs and the requirements of your tools when choosing an air compressor. By taking these factors into account, you can find the right air compressor to meet your needs and help you get the job done efficiently.


Extra features for compressors:

* Belt drive: Quiet operation

* Air cooling systems: Keep the machine cool and prevent overheating.

* Thermal protection: Stop the motor whenever the machine overheats.


  1. How to care for and maintain the air compressor?


Tip 1: Read the user manual: Never try to repair anything on the compressor before reading the user manual. Failure to follow this step could cost you down the line.


Tip 2: Clean the intake valves: To prevent the compressor from overheating, clean out any dirt or dust that has accumulated on its intake valves.


Tip 3: Install air filter: Without air filters, it will degrade the performance of pneumatic tools. The purity of air is most critical for painting. If not using air filters while painting, the painted surface will end up blotched and sandy.


Tip 4: Check the hoses regularly: Avoid the hoses cracked or damaged. These will cause leaks and then put undue strain on the rest of the compressor's components.


Tip 5: Clean heat exchangers: It's an important component for the compressor to reduce operating temperatures. Clean them regularly to keep their work normally and extend the compressor life. 


Tip 6: Clean the fuel tank: Remove the residual build from the fuel to preserve the life of the engine.


After selecting compressors, you also need the accessories to complete the projects efficiently.


Accessories compressors need as follows:

* Hose: The type of hose you need will depend on the kinds of work you're doing and the tools you use. The length and the diameter of the hoses determine the pressure that air tools can get. 

* Hose reel: Take out and put away the hose quickly and easily. If you haven’t found the suitable one, click the link. You can find the one you need.

* Gauge: Check the compressor's air pressure. Click the link, you can find the one you like.

* Air dryer: removes water vapor and particles from the air. Extending tool and compressor life.
