What Can I Do With a 30-Gallon Air Compressor?
The beauty of a 30-gallon air compressor is that it fills the gap between 20-gallon and 60-gallon, enabling you to take on commercial and home repair jobs. If you operate air tools, if you are restoring a classic car and need the back-up that a 30-gallon compressor gives, if you are working in a paint spray shop, all these tasks and many more benefit from using a 30-gallon air compressor.
Here are a few more uses to ponder:
- Auto repairs.
- Construction.
- Metal fabrication.
- Plasma cutting.
- Aerospace industry.
- Spray painting.
- Home repairs.
- Sculpting.
- Hobby use.
- Farm repairs.
- Commercial and industrial uses.
- Sandblasting.
- Waterblasting.
How to Choose the Best 30-Gallon Air Compressor
When selecting the 30-gallon air compressor that’s right for you, there are specific things you should be looking for. Here are a few considerations to bear in mind.
PSI
PSI or Pound Per Square Inch is the measure of pressure your compressor produces. Smaller air compressors have a weaker PSI, so when you switch to a 30-gallon model, you should expect enough PSI to perform commercial as well as home tasks.
You should expect your pressure levels to range between 125 and 155. When you consider that most air tools are rated at 80 PSI, that is ample pressure to power even the most hard-core tools.
When pairing tools to your compressor, a good rule of thumb is to leave a 20 percent gap in the PSI of the tool and the compressor. So, if your air tool has a PSI of 80 and the compressor has a PSI of 100, you should be fine.
Horsepower
This is the power rating of your motor. Smaller compressors produce 1 or 2 horsepower, but you should expect your 30-gallon compressor to function with 2 or 3 horsepower. Some models do go as high as 5, but that is the exception rather than the rule.
The motor’s horsepower is vital because it tells you how much pressure the compressor will create. It directly influences the tasks you can do, especially if you are working in a heavy-duty capacity in the commercial sector.
In the home, horsepower is still important but less of a concern as the compressor’s duties will be lighter and less demanding.
CFM
CFM, or Cubic Feet Per Minute, is the airflow rating of the compressor. A high CFM is crucial because there is little point in having an air compressor that produces a PSI of 155 and yet allows the compressed air to trickle out. It will seriously hinder your chances of a good outcome and struggle to power your air tools.
The CFM in 30-gallon air compressors should be between 5 and 10 CFM, although some models will produce more and some less. CFM is vital for jobs like sandblasting, where a high amount of pressure is required to deliver impact.
Loudness
It’s worth noting that whatever air compressor you get, it will be noisy. The best advice is to wear ear defenders when operating one. However, not all compressors are created equal. Volume levels range in decibels from the high 80s to as low as 70.
To give you an idea of equivalence, 70 dB is about the same volume as a normal conversation or office noise, whereas 80 dB is as noisy as a car doing 60 MPH with the windows open.
Portability
30-gallon air compressors are typically mounted on wheels and have large handles for added maneuverability. While they are heavy, they are portable and can be transported to the worksite. Because they are commercial-grade air compressors, 30-gallon models are a much better option than the heavier 60-gallon varieties.
60-gallon compressors are not portable and rarely come with wheels. So, if you are looking for maximum power as well as maneuverability, a 30-gallon air compressor is the best bet.
Price
The budget is a great leveler because no matter how badly you might want a particular model of air compressor, your finances will constrain you. Our best advice is to plumb for a compressor in the mid-price range. That way, it isn’t cheap and poorly constructed, or it won’t break the bank.
30-Gallon Air Compressor FAQs
Can You Paint a Car With a 30-Gallon Air Compressor?
A 30-gallon air compressor will cope just fine with painting a car, as long as the PSI of the spray gun matches the PSI of the compressor. And remember to leave a 20 percent difference in the tool’s pressure rating than the compressor.
You also need to consider the CFM values of the gun and the compressor, making sure they match as well.
How Much HP Does a 30-Gallon Air Compressor Need?
The horsepower needed varies between models and makes. Generally, for a 30-gallon air compressor to function properly, you will need a minimum of 2 horsepower, although some models can be as much as 5 horsepower, which increases your capabilities.
How To Drain a 30-Gallon Air Compressor?
The first thing you need to do is switch off the compressor and unplug it from the power supply. Ensure you remove all the attachments like air compressor hoses and tools and set the air pressure outlet to zero.
Place a drain pan under the valve and tilt the compressor so that when you open the valve, the water begins to flow out. Now open the valve, but be careful because pressurized air will escape rapidly before the moisture starts to drain away. When the fluid stops flowing, close the valve and store the compressor in a dry, flat location.
30-Gallon Compressors Really Impress
When 20 gallons is too small and 60 gallons is too large, you need to consider the benefits of a 30-gallon compressor. They offer that middle option where you can scale up the projects you take on while maintaining all the advantages of portability.
The next time you take a trip to the construction site or workshop, load a 30-gallon air compressor in your truck. You won’t regret it.
