What size air compressor do I need for air tools?

One of the most versatile and efficient forms of energy available is the compressed air. An air compressor is a cost efficient piece of equipment that has multiple functions. You can use it to complete your construction, automotive repair, maintenance, hobby, or to craft projects faster using the traditional tools. There are numerous benefits of having air tools. Accidental air leaks will not release any contaminants and the air tools last longer. They also have variable speed and torque control that enhances their performance. Choosing the size of an air compressor is an essential factor to consider if you are purchasing one for the first time.

 

Factors to consider when choosing the right size of air compressor

There are two steps you can follow if you want to choose the best size of an air compressor. First, you need to determine where you will use the air compressor. You also need to determine your power requirements.

Where will you use your compressor?

Air compressors are primarily distinguished by two main types; portable and stationary. The portable offers you flexibility in that they can be carried everywhere. They have a wide range of uses such as inflating tires, inflating air mattresses or sports equipment. You can also use them to power nail guns and impact wrenches. They are lighter compared to other models and are highly portable.

The stationary compressors cannot be carried easily from site to site. Not only are they large but also heavier than the portable compressors. They have a larger tank size that offers a greater volume of air as well as more power.

 

What are your power requirements?

There are two factors to consider when determining your power requirements; the air flow and the tank size. The required air flow can be measured in two ways, pounds per square inch (PSI) and cubic feet per minute (CFM). These measurements help determine the effectiveness of the air compressor when used in various occasions.

Air compressors operate primarily from the air that is stored (compressed) in the air tanks. As a result, the amount of air that is stored inside the compressor will determine the efficiency of certain tools. If you are using air tools that require a large amount of continuous air, you should consider having a larger tank size.

 

The different sizes of air compressors

Below is a rough guide to choosing the best tank size of air compressors. The theory behind this equipment is that the larger the tank compressor, the better the performance of the air tools. Purchasing from a reputable manufacturer will be the right thing to do. However, always remember that size matters when it comes to efficiency. The larger tanks will definitely cost more. Although you will be working on a fixed budget, never sacrifice on quality since it is a crucial factor when purchasing an air compressor.

  • 6-litre compressors

They are used for smaller projects such as nailing/stapling, spray painting, and tire inflating. This size of air compressors are compact, portable and offer high performance for consumer-grade applications. They have a low maintenance and are completely oil-less.

  • 24-litre compressors

They are fairly sized tanks used for slightly larger jobs. You can always pick something professional or a great DIY compressor with the numerous brands available. They also provide a great value for money.

  • 50-litre compressors

This size of air compressors is available in both portable and stationary versions. They were purposely designed for hobby and professional use. It is always possible to handle medium sized air tools to more demanding applications using a larger tank.

  • 100-litre compressors

Large capacity compressors come in petrol powered or electric options. They are suitable for consumer applications, semi-professional and commercial use. You will have higher benefits compared to the smaller versions because you spend less time filling up your receiver and you spend more time using your air tools.

  • 200+ compressors

If your budget is no longer a concern, you can go for the larger tanks ranging from 200 to 500 liters. They are huge capacity compressors which are perfect for workshop and commercial applications. They all come in stationary versions and are equipped with anti-vibration mounts. You have a wide variety of options to choose from such as electric, diesel or petrol powered sources.

 

Tank Style Compressors

The air compressors are available in different tank sizes and shapes. Choosing the right tank style will depend on where you want to use it as well as your taste and preferences. We have also highlighted the top picks that will give you a better idea of what to buy when making your purchasing decisions.

Applications of air compressors

Air compressors can be effective for both individual and commercial purposes. For consumer use, you will need the single tanks or ‘oil-less’ models since they are affordable. They are also made for minor household tasks like inflating tires, sports equipment, and toys. They are perfect for occasional pneumatic tool use. However, a consumer-grade compressor will not be sufficient if you intend to do a lot of home-improvement projects.

A professional-grade air compressor is the most appropriate for commercial use. They come in various designs and the primary distinguishing factor is that they are ‘oil-lubricated’. Typically, they have large single tanks or twin tanks with higher ratings in terms of hp and cfm. They are also more expensive compared to the consumer-grade air compressors. However, they are powerful and highly durable making them suitable for commercial use.
