10 Useful Tips To Consider Before You Buy A Piston Air Compressor

Are you having considerations about buying a piston air compressor to use for your work? Then you are in for a treat with our top ten list to guide you through the journey to your machine.

Air compressors cost you a lot of money, so it is good practices to read all the relevant information about them beforehand to understand how to choose a good machine. Look for air compressor reviews that provide you with different models, options and features to consider.

The wrong choice of air compressor will affect you in many ways: you may end up reducing your business’ productivity, receiving more customer complaints and lowering your profitability. That is not to mention the time you spend on dealing with the problematic machine that you have chosen.

Below are 10 factors to taken into consideration before buying a reciprocating air compressor.

  1. Type of compressor

There are currently 3 types of or piston air compressors on the market, including single stage compressor, dual stage compressor and twin compressor.Type of air compressor

Single stage compressors . They can compress air at a rate of 20 cubic foot per minute (CFM) at the 125 psi pressure.

Dual stage units will provide you with more compressing power. The air will undergoes two stages of compressing, through the use of two piston. The bigger piston will be responsible for compressing air during the first stage, which is the low pressure compressing. The smaller cylinder is in charge of compressing during the second, high pressure stage. The air is cooled down between the two stages.

A dual stage air compressor can have a capacity of up to 50 CFM, with a pressuring rate of 175 psi.

Based on your required amount of air and the time available for compressing, you can choose an appropriate type of compressor.

  1. Capacity and pressure

As you are choosing an air compressor, the most important criteria for the machine are its capacity and pressure. The capacity you want for a machine is calculated by adding all the air required to operate by the tools that you use for your work. Smaller tools use less air, whereas big tools will consumers a considerable amount of air that you have compressed.

To know what pressure you will require from the air compressor, check the requirements of the tools in your project.

It is advisable to buy a machine with more capacity than you need, as you may add more air tools for your project in the future. In addition, you should leave some “air” for it to breathe, right? Working at 100% percent capacity all the time is not good for a machine.

  1. Horse powerhorse power

Many people look at horse power when buying an air compressor, just like when they choose a car to buy. This is not necessary, as horse power is the combination of the capacity and pressure of the air compressor. You only need to look at these two criteria and forget about horse power.

  1. Electricity

The next thing you want to make sure is that your electricity system at home is able to provide energy for the air compressor to operate. What is the voltage of the electricity compared to the required voltage of the machine?

  1. Noise pollution

An air compressor will come with a lot of noise when they operate, so make sure you check the level of noise it can make before purchasing one.  You should ask the salesperson to test run the machine to have an idea of how it will sound when operating at your place.

Put some sound blocking object around the air compressor to lower the noise, but remember that air compressor produces a lot of heat during operation, so a cooling system may be needed.

  1. Storage tankcompressor Storage tank

An air compressor tank has sizes ranging from 40 to 80 gallon. The larger the tank is, the more air it can store to provide for your tools to operate, especially when the amount of air compressed cannot compensate for the amount consumed.

  1. Air filters

Compressed air may come out along with water and air, which is not suitable for some applications, such as painting. To produce clean, normal air, you can use filter that remove dirts, water and oil from it.

  1. Weight

Air compressors are usually heavy, so you should require the store to ship and install it at the place of your choice. You don’t want to carry on your own, trust me!

  1. Duty cycle

This is the amount of time that your air compressor can run without resting. If you need it to run for a whole day, opt for a 100% duty cycle air compressor, whereas a 50% duty cycle air compressor will work for you 10 minutes and rest for the rest 10 minutes.

  1. Miscellaneous

There are additional features that you might consider, but is not essential for the operation of air compressors:

  • Pressure regulators
  • Air connection
  • Direction of tank
  • Drains


Now that you have known all the important fact, hurry up and visit an air compressor store.
