Are Gas Powered Air Compressors Portable?
Gas air compressors are more portable than their electrically-powered counterparts because they don’t require the use of cords or electrical outlets. With a gas-powered air compressor, you can use your air tools anywhere you desire to work, from working on the house, on the car, or on the job site. Gas air compressors are perfect for maximizing portability and can be used in anywhere, even places without access to electricity.
How Do Gas Air Compressors Work?
The operation of gas air compressors are simple. There is a gasoline powered engine that turns an air pump either directly or by using a pully or gear system. The engines on a gas air compressor is similar to one that you would find on a lawnmower.
How Loud Are Gas Air Compressors?
Pretty loud. Think about it. These things have engine, and engines are always going to be louder than an electric motor. Unfortunately, the loud noise of these machines doesn’t work well for use around the house. Home improvement and construction contractors, however, will find that they are well suited for such an application.
This makes sense because if no one is home, there is no one to complain about the noise. The average air pressure for these models is between 90 and 100 PSI. For reference, a tool like a paint sprayer gun may only require 40 PSI or so. Some devices, such as a grease gun, need as much as 150 PSI.
1.DeWalt DXCMTA5090412 – Best Gas Air Compressor For The Money
DeWalt has always been a favorite brand for many contractors as a high-quality power tool. The DeWalt DXCMTA5090412 is no acceptation. This air compressor has all the professional features that a DIY enthusiast would want.
Lightweight, Economical, And Reliable Gas Air Compressor
Instrumental in this air compressors unrivaled performance is the 208 CC (Cubic Centimetre) engine. This power plant combines economy and reliability by having excellent fuel efficiency and minimal maintenance requirements. The DeWalt DX Series 6 HP engine runs an oil-free, direct-drive air compressor pump. The result is a steady 5.0 CFM at 90 psi or 6.9 CFM at 40 psi. We also recognize the respectable portability of this product, which weighs in at only 74 pounds.
Built To Last And Backed Up By DeWalt
This machine really excels in rough environments. This is thanks to it’s cast iron sleeve and sturdy construction. Don’t forget that this reliable gas air compressor also comes with a 1-year limited warranty, which is good enough, considering that this is an older model that already has a proven track record of reliability. The unit comes with tool and tank pressure gauges, a one hand quick-connector, and 1/4″ regulator.
Attractive And Strong Design Gas Air Compressor
Another thing we really liked about this air compressor was its design. I mean, look at it. You really know a DeWalt product when you see one. They are known for having really well manufactured products that can stand up to the test of time while also looking great.

The compressor kicks on at around 125 PSI to keep the tank full.
Twin Stage Cooling System
The pump uses a two part cooling system, which helps to maintain lower operating temperatures. When a machine runs cooler, it will generally be more efficient. Also, heat plays a major role in wear and tear, so avoiding higher temperatures increases the over all service life of the machine.
The fact that the unit is oil-free means that it’ll have minimal maintenance requirements. The construction of this air compressor is sturdy thanks to its precisely machined thermally stable aluminum parts. This model unit also comes with a quick-connector, tool and tank gauges, and a regulator.
Another thing we liked about this gas powered air compressor was the use of twin tanks. We also liked the ergonomic handles, as they make portability easier. Its got rubber feet to help absorb vibration, and a ‘wrap around’ metal frame that keeps the engine safe when it’s being moved.

Before buying a gas powered air compressor, there are a few key factors to consider. These things include portability, power, and noise level. Also, it’s important to understand some of the terms used when discussing gas air compressors such as dB, PSI, and HP.
Air Compressor Grade
Gas air compressors can be categorized as commercial, consumer, and contractor grade. When determining which category to buy, it is crucial to consider the type of job, the frequency of use, and the number of tools to be powered simultaneously.
For home improvement projects where grid power is not available, a consumer-grade unit is ideal. For bigger jobs, such as construction projects, a contractor-grade group is preferable. Factories and manufacturing firms, however, need something even more potent. They use commercial grade models which offer the highest performance possible and can provide a steady amount of air over a long period of time. You can also find them in amusement parks, large automotive garages, and oil rigs.
PSI: Air Pressure
Air pressure inside the tank is given in PSI (Pounds per Square Inch), with most compressors having 115 PSI, which is slightly higher than the 90 PSI required by most air tools. Its not unusual to find powerful compressors with as much as 150 PSI, though.
CFM: Cubic Feet per Minute
More important is the amount of air coming from a compressor over a period of time. This is know as CFM (Cubic Feet per Minute). If you are using a tool continuously, you will need to supply higher CFM.
That is why a continually rotating smoother uses 8 CFM, while a framing nailer works with just 2.8 CFM. From a professional’s experience, determining the minimum rating for CFM is simple if you have the tool rating as given by the manufacturer. Take the rating and multiply it by 1.5. For example, if the rating on the tool is 2 CFM, the minimum requirement to power, it should be 3 CFM. Concentrate on the CFM rating at 90 PSI (Pound per Square Inch), as most tools run on this weight.
Horsepower is a measure of the capability of the motor. Since the capacity of the engine has a massive impact on every aspect of compressor performance, you want to pay attention to this. Because of the rampant inflation of indicated HP, focus on the rated amperage to determine the power of the engine.
dB: Noise Level
These are machines with several moving parts that are powered by gasoline engines. None of them are going to be quiet machines. Metal components banging against each other can be extremely loud.
Noise levels are measure in dB (decibels). Note that the increase is exponential, meaning that 60 dB is more than three times 20 dB. If you will be working indoors, you want to make sure to get a model with the lowest possible dB rating. If you are out in the open, you get get by with a little higher dB without it becoming an issue.
Compressor Tank Size
If you are using several tools continuously, you’ll need a larger tank. If your tank is too small for the job, your motor will have to do more work to compensate. This can be loud and expensive. In contrast, if you’re doing intermittent work you can get away with having a smaller tank size.
Tanks can be as big as 80 gallons, although a single tool may only require up to 5 gallons. Therefore, in simple terms, the choice of tank size depends on the type of work and the type/number of tools being powered. Larger tanks combine excellently with high PSI (Pound per Square Inch), but the shift towards portable units maintains the need for the right balance between PSI (Pound per Square Inch) and tank size.
The price is dependent on whether the gas air compressor is a commercial, contractor, or consumer-grade. Expect to pay $10,000+ for a commercial-grade unit. Contractor grade units are more affordable, with prices ranging from $150 to $5,500. The most affordable gas air compressors are in the consumer-grade category. You can get a unit for as little as $15, but the best models will set you back up to $2,500.
For a contractor who has to be on the move, the portability of the product is a requirement. The majority of contractor-grade units are easy to transport. Some can even be moved rather easily with one hand. If you are looking for portability, check out our guide to portable air compressors.
The air compressor industry is constantly innovating and creating new designs and models. Innovation is a great thing, but all the new terms and acronyms can make it somewhat confusing to understand it all. We hope to have cleared up a few of those things for you, so you’ll be able to make a more informed purchasing decision.
