When should we use a 6-Gallon Air Compressor?

An air compressor can be used for various tasks, from inflating tires to powering air tools. But with so many options available there, it can be challenging to know which one is right for you.

A 6-gallon air compressor is powerful yet portable. These compressors typically have enough power to handle light-duty tasks where the continuous air supply is not required, such as in most home and automotive applications. However, they are still small enough to transport easily.

When deciding whether or not a 6-gallon air compressor is right for you, consider the types of work you will be using it for and the amount of space you have available.

A larger model will be more suitable if you need a powerful air compressor to handle multiple applications or larger projects.

A 6-gallon air compressor is commonly used for-

  • Filling tires
  • powering small air tools
  • Inflating sports equipment
  • Home or shop cleaning
  • Blow up pool toys

CFM, PSI, HP, and tank size of a 6-gallon air compressor


The CFM of a 6-gallon air compressor is around 4 CFM @40 PSI and 3 CFM @90 PSI. A compressor CFM 4 means that it can pump up to 4 gallons of air per minute. The CFM measures the compressor’s efficiency, and it is calculated by dividing the volume of air that the compressor can pump in one minute by the number of gallons of air that the compressor can hold.

A higher CFM rating means the compressor is more efficient and can pump more air in a shorter period. So, it is crucial to consider the right CFM rating of an air compressor that will meet your needs.


The PSI rating of a 6-gallon air compressor is around 125 PSI, and the maximum is 155 PSI. This means that the compressor can pump 125 pounds per square inch of air into the tank. The 6-gallon size is a popular choice for home use, as it is small enough to be easily portable but still has enough capacity to power most tools.

The 110 to 150 PSI rating is also suitable for a range of applications, such as inflation, stapling, and nailing. On the contrary, selecting a higher-powered compressor with a higher PSI rating is better for heavy-duty tasks such as sanding or painting.


The HP rating of a 6-gallon air compressor depends on the make and model of the compressor. For example, a Craftsman 6-gallon air compressor has an HP rating of 1.5. A similar-sized compressor from Viair likely has a different HP rating.

It’s essential to consult the owner’s manual or contact the manufacturer to find out the HP rating for a specific air compressor. The amount of horsepower is crucial because it dictates how much power the compressor can deliver.

A higher HP rating means more power and faster inflation times. Generally, a 6-gallon air compressor with a higher HP rating will be more expensive than one with a lower HP rating.

Tank size

A 6-gallon air compressor typically has a tank size of 24 liters. This means that the compressor can simultaneously hold up to 24 liters of air. The tank size is important to consider when choosing an air compressor, as it determines how much air the compressor can accumulate and how fast it can be used.

A larger tank size will allow the compressor to run for extended periods without needing to be refilled, which is ideal for heavy-duty tasks. For smaller projects, a smaller tank size will be sufficient. Ultimately, the choice of tank size depends on the intended use of the air compressor.

How long does it take to fill a 6-gallon air compressor?

A 6-gallon air compressor is standard for many homes and small businesses. They are portable and relatively easy to operate. The time it takes to fill a 6-gallon air compressor will depend on the model and make of the compressor, the PSI (pounds per square inch) rating, and the motor’s capacity.

Generally, it will take between 2 and 5 minutes to fill a 6-gallon air compressor from empty. If you are using a higher-capacity compressor or one with a higher PSI rating, it will take less time. Conversely, if you are using a lower-capacity compressor or one with a lower PSI rating, it may take longer.

How long does a 6 gallon air compressor last?

Air compressors are vital equipment for many businesses but can also be a significant investment. One of the common queries we get asked is how long a 6-gallon air compressor lasts. To understand this, it’s crucial to know the various factors that can impact the lifespan of an air compressor.

First, it’s important to remember that all air compressors require regular maintenance in order to function properly. This includes tasks like changing the oil and filter, checking the belts and hoses, and monitoring the pressure gauge. Neglecting these simple maintenance tasks can lead to premature wear and tear and ultimately shorten the lifespan of your air compressor.

In addition, it’s vital to choose an air compressor that is sized correctly for your needs. A too small air compressor will have to work harder to keep up with demand, leading to overheating and reduced efficiency.

On the other hand, an air compressor that is too large will be less efficient and use more energy than necessary. By selecting the correct size air compressor for your needs, you can ensure that it has a long and productive life. With proper care and maintenance, 6-gallon air compressors can provide years of reliable service.

Will a 6 gallon air compressor run an impact wrench?

An impact wrench is a power and handy tool for loosening or tightening bolts and nuts that are stubbornly stuck. The high torque delivered by the spinning gears can quickly break them free. An air compressor provides the power needed to run the impact wrench; without it, you’d be using elbow grease (and lots of it).

A 6-gallon air compressor should be able to handle most light-duty tasks like this as long as you use the right attachments and follow some simple advice.

A 6-gallon air compressor can also run an impact wrench, but it does not have enough power to operate the tool at its full potential. The size of the compressor is not the only factor determining its compatibility with an impact wrench; the air pressure and flow rate are also important considerations.

Most impact wrenches require at least 90 PSI to function correctly, and a 6-gallon compressor typically produces around 125 PSI. However, the flow rate is more likely to be a limiting factor; a 6-gallon compressor typically has a flow rate of around 4 CFM, while most powerful impact wrenches require at least 6 CFM to operate appropriately.

Finally, a 6-gallon air compressor can technically run 1/4-inch and 3/8-inch impact wrench, but it is not powerful enough to run 1/2-inch, 3/4-inch, and 1-inch impact wrench. So you can not use these powerful impact wrenches effectively with a 6-gallon air compressor.

What type of tools can a 6-gallon air compressor run?

It is small and lightweight yet still powerful enough to handle most projects. Regarding compatibility, most 6-gallon air compressors can be used with various air tools, such as impact wrenches, ratchets, and airbrushes. An air compressor is also considered an essential tool for many homeowners.

Will a 6-Gallon Air Compressor Fill a Car Tire?

Most car tires require about 30-35 PSI of air pressure, measured in pounds per square inch. A 6-gallon air compressor can deliver around 125 PSI, so they should be able to fill a car tire.

The tank size of an air compressor will affect how long it takes to fill the tire. For example, if the compressor only delivers 2 CFM (cubic feet per minute), it will take about 5 minutes to fill a tire. If the compressor delivers 4 CFM, it will take about 2 to 3 minutes to fill a tire.

It’s also important to ensure that the 6-gallon air compressor has a safety valve that can be used to release pressure if necessary. Otherwise, the air pressure could build up too much and cause the tire to explode.

Are 6 Gallon Air Compressors Worth It?

Air compressors are essential for many trades and DIY projects, but choosing the suitable model can be tricky. One of the most common size options is the 6-gallon air compressor. But is a 6-gallon air compressor worth the investment? There are a few considerable things when deciding if a 6-gallon air compressor is right for you.

Firstly, think about where you will be utilizing it. A smaller model might suffice if you only need it for light-duty tasks like inflating tires or powering a small nail gun. However, a larger unit will be more effective if you need it for more heavy-duty applications like running a powerful impact wrench or sandblaster.

Secondly, consider the portability of the unit. A 6-gallon air compressor is typically easy to move around, making it a good choice for those who need to take it on job sites or to different properties.

Air compressors produce noise while running, so if you plan on using them in an enclosed space or close to others, a quieter model might be worth the extra expense.

Finally, whether or not a 6-gallon air compressor is worth the investment depends on your specific needs and preferences. However, they generally offer a good balance of power and portability and can be an excellent choice for those needing a mid-budget air compressor for light applications.

Final thoughts

Will a 6-gallon air compressor run an impact wrench? I think the above article will help you to get the answer. The compressed air released from a 6-gallon compressor can generate up to 150 pounds of force; this PSI is more than enough to power most small-sized wrenches on the market. This makes them a popular choice for automotive repair work and other small projects where the continuous air supply is not required for extended periods.

However its CFM rating is deficient for running a powerful impact wrench. So, avoiding a 6-gallon air compressor for an impact wrench is better.
