What Size Air Compressor For Impact Wrench

What Size Air Compressor For Impact WrenchBefore you buy an air compressor, it’s vital that you find out what your requirements are. Answer some basic questions below and you will find out

Question 1: What kind of projects will I do?

Frequent maintenance tasks or larger construction projects? Car repair or house upgrade? Someone who put a warehouse in their backyard would obviously need something stronger than someone who likes to surf through some figurines.

Question 2: What kind of air tools would I use?

If you have some tools that need continuous air such as sandblasting equipment, you should provide them with the air compressor with more airflow and bigger tanks.

For operating a brad nailer or something like this, just the small compressor can do it well.

Question 3: What kind of energy sources are available?

Most compressors can plug into standard household sockets, but some larger compressors need 240-volt power. Another one is powered by gasoline when a power outlet is simply not available.

Question 4: How much space do I have?

You will need a lot of space if you want to pick up the air compressor with big tanks. Therefore, it is necessary to look for the one that fits the available space in your house.

It is recommended to use a pancake 6-gallon air compressor as it fits well with almost every garage.

Question 5: Where will I use it?

If most of your projects will be done in one place (such as a garage or a factory), you will need to pay attention to the design of the compressor.

However, if you plan to move your tools regularly, you will want to find a lightweight and easy to carry compressor or have wheels to move better.

Ask yourself these questions then you will have some ideas of what size air compressor you need.

There are 3 main factors you need to consider when choosing an air compressor. They are: The Type Of Airflow Needed, Tank Size Compressors and The Tank Style Of The Compressor

The Type Of Airflow Needed

The Type Of Airflow NeededIf you usually check for the specification of the air compressor, you will probably know the PSI( pounds per square inch) and the CFM( cubic feet per minute). These are the 2 main factors to determine the efficiency of the air compressor.

To choose the right compressor, it is important to know the PSI and CFM required.

  • For impact wrench 0,5- inch, the CFM is commonly not over 4.0 and PSI is 90
  • For impact wrench 0.75- inch, the CFM is usually 5.0 and PSI is 90

On the condition that you have a lot of wrenches but you use only one compressor, it is advisable to use the one that is able to surpass the PSI and CFM needs of your most powerful appliances to ensure the efficiency and good performance of your air compressor.

Tank Size Compressors

There is a storage tank in all air compressors that is capable of containing the necessary air. The amount of air your tank can store will show how your impact wrench works.

You have to use a bigger tank when you use many tools at a time because when you use a lot of tools at the same time, more air is needed. In case you have few tools, it is fine to use a smaller tank.

To sum up, you have to pick up a tank that is able to power all the tools you use.

The Tank Style Of The Compressor

The Tank Style Of The CompressorThe tank style of the air compressor has no effect on the impact wrench’s performance. However, it is important when it comes to the amount of available floor space, mobility, compressor size as well as applicability

When using an impact wrench, it is advisable for you to choose the most suitable compressors that can help you work easily in every place. There are many tank styles and sizes available, it is easy for you to choose the one that fits you impact wrench the most.

Because the size of the compressor is very important when using an impact wrench, ergonomic design is something that almost everyone fancy. There are small tanks that you can carry easily.

There are also some other popular tank types you can choose including pancake, hotdog, pontoon, vertical mobile, horizontal mobility, and wheelbarrow. Make sure you choose the one that fits your needs.

Other Factors

Other FactorsThere are also some other important factors that you need to consider when you want to buy an air compressor that goes well with your impact wrench

Durability

Product with a low cost usually brings about many annoying problems. For example, compressors that stand too much stress can be broken easily and fast.

Therefore, you should buy a reliable brand to ensure its product is built to last. Moreover, you can also save more money because you don’t need to pay for regular repair.

Capacity

The capacity of the air compressor is also necessary to consider when choosing impact wrench, especially in tire and brake shops.

Although 4 or 5 gallons of air will allow you to pull one or two tires before recharging, when it comes to pulling everything you will want something in the order of 15 gallons or more.

Mobility

We tend to use our impact wrench around garages or stores. Since there is only one limit line related to your tools, it is likely that you will have to reposition your compressor at least once.

For most people, unless you have a store, you’ll want something with a smaller capacity for easy movement.

It also means that wheels and handles are necessary to make sure you can get what you need.

Price

The amount of money you are willing to spend on your compressor depends largely on how often you use the device. It is worth spending a few extra dollars if you use your compressor almost every day.

On the other hand, if you’re just a weekend warrior, you might want to save a bit and invest in a variety of tools.
