Well, you can handle hundreds of small scale projects with this small but efficient air compressor. No doubt, getting hands-on the big project is not in the capacity of a 3-gallon air compressor, but still, it can provide a lot of benefits when you’re dealing with small to medium scale projects.
Without further ado, let’s have a look at the applications of a 3 Gallon Air Compressor.
What Can a 3 Gallon Air Compressor Do?
A 3 Gallon air compressor can do your various daily life and professional jobs, Such as:Â
- Blowing DustÂ
- Nail Gun
- Stapling Gun
- Drilling Gun
- Painting Jobs
- Inflating Tires
- Inflating Mattresses
- Sanding & Sandblasting
- Spraying Crops
Let’s discuss each application to help you understand it better.Â
1. Blowing Dust
For dusting, the required air pressure is very low; hence a three-gallon tank air compressor is best for blowing dust. The compressor is ideal and easily transferable from one place to another. You can easily clean appliances, hardware and tools, furniture and upholstery, and houseplants with a 3-gallon compressor, and it can clean the parts of the machine that are not accessible.
2. Light Duty Pneumatic Tools
With the 3-gallon air compressor, you can effectively perform small and light projects using small tools. Although most pneumatic tools are heavy, some require less air pressure and are smaller.
- Nail gun, stapling gun, bolting, fastening, drilling gun, timing.
With a 3-gallon air compressor, you can nail or trim efficiently, and you do not need a heavy-duty model.
3. Small Scale Painting Jobs
This 3-gallon air compressor is convenient and small, ideal for a paint sprayer. You can efficiently do personal painting projects with it. Door and wall spraying is possible, but the compressor will need rest before spraying another wall.
4. Inflating Bike Tires
Typically, you can simply do medium-scale inflating with a 2-3 gallon air compressor. To fill tires of mountain bikes, the pressure needs to be 30-35 PSI, the narrow bike tire pressure needs to be 100-130 PSI, and the hybrid tire pressure needs to be 40-70 PSI. So, it is excellent for the house owner to have a 2-3 gallon compressor while shops might need a larger compressor for car tires, SUVs, and trucks.
5. Inflating Pools
The 3-gallon air compressor is ideal for inflating pools, kids pools, and smaller pools, as they need less PSI, which a 3-gallon air compressor can easily do. The bigger ones need a heavy-duty compressor.
6. Inflating Air Mattresses
The 3-gallon air tank is the perfect choice to inflate mattresses, as they do not need a lot of pressure, and you can fill them with small compressors.
7. Medium or Low-Level Sanding & Sandblasting
The tank’s capacity isn’t the only factor to consider; you also need to consider CFM. For commercial or industrial scale, sanding and blasting require 10-100 CFM at 90-100 PSI. The 3-gallon air compressor is not capable of sanding and blasting, and you may need a bigger compressor.
8. Spraying Crops
The 3-gallon air compressor is ideal for spraying crops with both medicines and water. It does not need to be a heavy compressor, and a simple compressor can also do this job.
CFM, PSI, & HP Ratings of a 3 Gallon Air Compressor
CFM gives the measurement of the compressors, which refers to the air volume of the compressor at the given time and pressure The 3-gallon air compressor produces 0.5 CFM at 90 PSI or 1 CFM at 40 PSI. It plays a role in determining the best tools to use with the compressor. Most CFM is between 0.5-1, but it can only be 2.6 in some new models.
PSI determines how much air pressure an air compressor can generate, and it refers to the max pressure of the compressor, at which it shuts off. The maximum PSI of the 3-gallon air compressor is 90-150 PSI, but 110 PSI is the most common.
The horsepower of the compressor determines the power and CFM of the compressor. If the HP is higher, the CFM will be higher. The HP also plays a role in consuming power and noise levels. Mostly higher HP means the compressor is powerful and will generate loud noise. The 3-gallon air compressor usually has 0.33-1.5 horsepower, and â…“ horsepower is the most common.
Will a 3 Gallon Air Compressor Run an Impact Wrench?
The 3-gallon air compressor is not capable of impact wrenches, and even the small impact wrenches need about 1-1.5 CFM. For using impact wrenches, you need a maximum of 4-5 CFM at 90 PSI for a 1/2 wrench. The impact wrench with 1 requires 10 CFM at 90 PSI, and the 3/8 wrench needs 3 CFM at 90 PSI.
Is a 3-Gallon Air Compressor Good?
The air compressor is suitable for dozens of small projects, and it is ideal for brand nailing, finishing nailers, staplers, and inflation. The compressor is lightweight, and most importantly, it is portable. So, yes, the 3-gallon compressor is good if you use it only on small tasks.
How Long Does a 3-gallon Air Compressor last?
The 3-gallon air compressor is the most common and convenient compressor for small projects. The compressor has the capability of lasting 10-15 years. However, it can only be possible when you take proper care of its maintenance.
Most 3-gallon air compressors are oil-free, so they do not require routine maintenance, but continuous use can wear them out quickly.
Maintaining it and allowing it to rest, and not using your air compressor continuously will make it last longer.
What is a Central Pneumatic Air Compressor?
The central pneumatic air compressor is manufactured by a very reputed brand, Harbor Freight, who have been in this field for 40 years. They are trusted and have high-quality compressors also the prices of their products are reasonable.
In the brand, the most common compressors are 3-gallon air compressors. It is a low budget, and it is for small projects. The compressor is available in pancake and hot dog shape having 0.6 CFM at 90 PSI.
Airbrushing, brand nailing, stapling, inflating bike tires, and toys are the small things that a small compressor with a 3-gallon air tank can efficiently perform.
How to Choose a Small Air Compressor?
When we talk about small air compressors, we know that we will not do heavy work with the compressor. With small compressors, heavy tools like pneumatic wrenches cannot be used. You should look for a heavy-duty compressor with a great tank size if you want to do hard work.
You can use these tips to find a suitable small air compressor for your needs. Make sure the compressor has the following features:
When choosing an air compressor, tank size is one of the critical factors you should consider. 2-3 gallon tanks are the best small compressors, and the larger tank is for more heavy projects.
A small compressor is ideal for regular use and basic household needs. In addition to the tank size, the CFM is also important.
CFM, which means cubic feet per minute, gives you the speed of the small air compressor. CFM is the primary component to look at when you want to choose small compressors. The 3-gallon compressor, which comes with 2.6 CFM, is the best for small projects and has a maximum of 135 PSI.
When it comes to small compressors, most of them are between 60-80dB. It may seem different to someone who does not know much about this, but it can be the loudest at 80 decibels and the quietest at 60 decibels. If you need the compressor inside or at a quiet place, look for a 60dB or less.
Portability is not only about the weight. The small compressor is relatively light. However, it is also vital to look at the shape of the compressor. The slim air compressors are not awkward and easy to carry. However, the wider one feels and looks awkward while taking from one place to another.
Oil or Oil-Less
Nowadays, almost all the small air compressors which exist are oil-free. Being oil-free, they do not need oil maintenance regularly or ever. However, they get worn out quickly. In this sense, oil-lubricated ones are good and last longer.
