4 Vital Factors To Consider When Buying An Air Compressor

Posted on29/07/2022

Air compressors are a useful addition to any business. They have numerous functions, from powering small equipment to large industrial applications. However, to enjoy the full benefits of an air compressor, it is necessary to choose the suitable air compressor according to your business needs. This might not be easy, especially if you know little about air compressors.

Rotary screw compressors, pistons, stationary, and portable are some of the types of air compressors you can choose from. With so many options, it can indeed be tough to find a suitable air compressor for you. This article lists four essential factors you should consider when purchasing an air compressor in Singapore.

 1. Type of Compressor

There are several types of air compressors, but the most common ones are the piston and portable air compressors. A piston compressor has a motor that prompts air pressure during depletion. The more it is used, the more the air pressure increases. Piston compressors need heavy-duty maintenance and ample space for a tank to keep the equipment in one place. Hence, piston compressors are ideal for commercial use.

Portable air compressors, on the other hand, do not have tanks. Hence, they do not require much space and are easier to move. A portable air compressor is typically used to supply compressed air on road works, construction sites, or whenever people require compressed air where the other types of compressors are not suitable. Moreover, since it is compact and easy to use, a portable air compressor works well for household use.  

2. CFM Measurement

The Cubic Feet per Minute (CFM) measure is another essential factor when choosing an air compressor. Determining the CFM is crucial, as it will indicate the pressure you will obtain from the air compressor per minute. For instance, if you need to power several tools simultaneously, you will need a higher CFM rating. Usually, CFM is determined using the PSI range.

However, when measuring the CFM, remember that certain environmental factors can affect the CFM rating. These include temperature, humidity, and altitude. Other factors like atmospheric pressure, heat dissipation, and friction can also have an impact but only on some air compressors.

3. Size

Air compressors come in different sizes, and knowing the right size is vital to ensure that your chosen air compressor meets all your needs and applications. Air compressor sizes are usually classified into consumer-grade, professional-grade, and industrial-grade.

Consumer-grade air compressors are small and portable and are typically used for small projects or tasks, such as inflating tyres. On the other hand, professional-grade air compressors are larger and can be used to power numerous air tools in one go. However, industrial-grade air compressors are the ideal choice for continuous use. They usually have a more durable design and can operate at a constant temperature no matter the demand.

4. Features

One of the most useful tips to follow when searching for an air compressor is to look at its different features. Here are some of the best features you can see in an efficient air compressor:

  • Belt drive – enables quiet operations
  • Multiple couplers – allows you to use numerous tools at once
  • Oil-free pump – minimises the need for time-consuming maintenance
  • Air cooling systems – helps keep the machine cool and prevent overheating
  • Thermal protection – stop the motor whenever the machine overheats
  • Cord wrap – enables easy carrying and storage of the power cord
  • Roll cage – protects the compressor from damage whenever it is moved or used on-site
  • Ball valve drain – helps avoid condensation within the tank by allowing the drainage of the air tank whenever necessary


Compressor type, CFM measurement, size, and features are only some of the essential factors you need to consider before purchasing an air compressor for your business. Considering these factors will help you ensure that your chosen air compressor will meet the needs and applications your business requires. Indeed, to get the best value for your money, it is necessary to select a compressor in Singapore that is precisely right for you!
