  • Versatility: The portable air compressors are designed to suit a wide range of industrial purposes.

Portable Air Compressor Buying guide

It is imperative to know how it works, its types, and other crucial factors involved in choosing the best portable air compressor. These factors include:

1.   Air Flow

    In general, the airflow is measured in terms of cubic feet per minute (CFM), which helps you understand how much air the compressor can provide to power your tires or tools. To calculate the required CFM of a tool, multiply the tool’s provided CF by 1.5. The CFM for some commonly used power tools are:

  • Angle grinder: 5 to 8 CFM
  • Brad nailer: 3 CFM
  • Pneumatic drill: 3 to 6 CFM
  • HVLP spray gun: 12 CFM

2.   Duty Cycle

The duty cycle refers to the length of time the device can run before it takes a break to cool down. It also refers to how long it needs to cool, and it measures in percentage. Some of the high-performance models have a thermal protection feature that automatically shuts off the machine when it reaches a specific temperature. An air compressor’s duty cycle is the time it can operate at 100 PSI and a temperature of 72 degrees before it needs to be turned off to cool down.  If the air compressor is working during extreme temperature changes, the amount of cooling time required will vary. Duty cycles can be stated in the following percentages:

  • 10% duty cycle – 1 minute on and 9 mins off
  • 20% duty cycle – should run for 2 minutes on and 8 minutes off
  • 30% duty cycle – 3 minutes on and 7 minutes off
  • 50% duty cycle – 5 minutes on and 5 minutes off
  • 100% duty cycle – can run on nonstop duty

What is best for you depends on your use case. The higher the duty cycle, the more expensive the air compressor will be.

3.   Power Source

Portable air compressors are powered by gas or electricity. Except for the smaller air inflators, electric air compressors use a mains supply. The advantage is that they don’t produce smoke, need less maintenance, and are the best choice for indoor applications. Gas-powered air compressors can be used in locations where there is no mains supply. They can also be high performance and comfortable to use, but should be used outside or in a well-ventilated area. As with each gas engine, good maintenance is essential to make the machine last longer.

4.   Cord length

For easy use, your air compressor should have a long power cord. Some portable air compressors have a 10 feet long power cord while others have a 15 feet long power cord. Choosing the one with a longer power cord (15 feet) is more practical without the need for an extension cord.

5.   Tank Size

Many portable air compressors come with a tank capacity of up to 6 gallons. Before buying, it is essential to check that the air compressor tank size and capacity suit the project you plan to do. For domestic compressors, a small tank of approximately 0 to 3-gallon tank capacity works best. Using a small tank with medium or large projects will result in a waste of energy. It takes longer to fill the tank and will have more wear and tear. A larger tank with at least 5 to 6 gallons of tank size would better accommodate heavy applications/more extensive projects.

6.   Maximum pressure

Before buying an air compressor to power your air tool or inflate your tires, remember to check the maximum pressure limit. In terms of Pound per square inch (PSI), air pressure is measured.  Please note that a higher PSI means a smaller tank will be able to hold more air. A safe purchasing bet would be getting a smaller device with a higher PSI to ensure effective performance. 

7.   Power Draw

For air compressors powered by a gas engine or the mains supply, the importance of the efficieny will depend significantly on your use case. If you only use your machine sparsely, the energy cost will not be very high. But when you use your air compressor all the time, the energy cost can add up. Choosing a more efficient model can save you a lot of energy cost.

In the case of a portable air compressor powered from your car battery (12V models), power usage can be crucial. You do not want to have an empty car battery after your job is done. So check how much your machine is using.

8.   Price

You can find air compressor models in a wide range of budgets. Depending on the type of air compressor, there will be cheaper brands and more expensive brands. Define upfront the features you need and the size of your budget. Don’t forget to include maintenance costs, particularly when you want to choose a gas-powered machine.

9.    Other features of an air compressor

To make your work more comfortable, portable air compressors have a range of options that you should check before making purchases. Some of these are:

  • Belt drive: It enables you to change the airflow and pressure according to your requirements flexibly. They are less costly and easy to mount and maintain, but they are not ideal for high temperatures or harsh environments.
  • Horizontal/vertical tanks: The Vertical tank would take up less space, while the horizontal tank is more portable.
  • Cast Iron components: The air compressor design is mainly available in standards cylinders, except for a few piston types. Cast iron crankcase, crankshaft, flywheel, or valve seats are available in these piston style versions, which add versatility to the air compressor.
  •  ASME parts: The American Society of Mechanical Engineers has set codes and standards that an air compressor’s parts or components should meet.
  • Low oil protection: When the oil levels are low, the part will shut off the compressor, thus avoiding downtime and costly repairs, which can be caused by low levels of fluid or oil.
  • Continuous speed: By changing the airflow according to specifications, the constant speed feature will make the engine run continuously.
  • Auto start or stop: This feature automatically helps you turn on the device whenever air is required and turns it off when the tank is full.
  • Dual Control: This allows you to set your air compressor run either in a continuous mode or an auto start/stop mode.

From the list of features, it is clear that there are many things to consider when looking for a portable air compressor. It might seem like a lot, but the truth is, if you want to have a smooth operation of your air compressor, it is best to put all these factors into consideration.

Maintaining an Air Compressor

Like any other mechanical device, it is essential to perform routine maintenance:
