Buyers Guide For Portable Air Compressors
If you’re in the market for a portable air compressor, it can be quite the daunting process to sift through the seemingly endless amount of options out there. Picking the right one is important. Not only do you want something that works, but you also want it to last. This guide will help you sort through all the things to look for and factors to consider when deciding on buying a portable air compressor.
What To Consider When Choosing
With so many options in terms of design and functionality, picking the best air compressor can be a challenge. Before deciding on a specific model, let’s examine the most crucial aspects.
Power Source
Air compressors use either electricity or gas as their energy source. Since they don’t produce any emissions, electric devices are ideal for use indoors, where they may be safely used without causing any harm to those in the vicinity. Compressors that run on gas are frequently more powerful and more portable than their electric counterparts. The disadvantage is that they require open air or good ventilation when in use.
Power
There is a direct correlation between the horsepower rating of an air compressor’s motor and the machine’s performance. For most purposes, a moderately strong air compressor will suffice; but, a more potent one will fill its tank much more quickly.
The highest pressure that a compressor can generate is also related to its horse power. Ideally, a small electric motor would have half a horse power, whereas gas-powered alternatives may use up to five. There’s that pesky power source to think about again.
An electric air compressor is sufficient for most home improvement tasks. A gas-powered compressor could be useful when transporting tools to far-flung destinations.
Maximum Pressure
Different models of portable air compressors can produce air at different maximum pressures, which are expressed in pounds per square inch (psi). One type may reach a pressure of 120 psi, while another may generate pressure of 150 or even 180 psi.
Some instruments need a higher amount of force applied to them in order to function, thus it’s crucial to be aware of the maximum pressure that they can withstand. Compressors with pressure more than 120 psi are usually adequate for usage in a garage or workshop.
Air Delivery
When shopping for an air compressor, one of the most crucial features to consider is the machine’s ability to supply air, which in turn determines what kind of air tools may be utilized with the compressor. CFM and SCFM represent the quantity of air delivered in cubic feet per minute – the volume of air delivered for one minute at a certain pressure.
Using the cubic feet per minute (CFM) rate at 90 PSI is the gold standard for comparing air compressors. This allows for a more reliable evaluation. You should keep in mind that an air compressor rated at 2 CFM at 90 PSI may actually deliver much less airflow while operating at a higher pressure. Always make sure you have everything your tools require to function properly.
Tank Size
To hold the compressed air, most bigger air compressors have a tank attached to them. The bigger the tank, the longer the tools may be used before the compressor needs to be restarted. A bigger tank, usually 6 gallons or more, will be necessary if you plan on employing tools that consume a lot of air.
Noise Rating
In the past, air compressors were massive, noisy equipment. Manufacturers of modern tools are aware of this. A typical industrial machine operates at a volume of around 70 dB, which is about the same as a washing machine.
Weight
A portable air compressor is one that can be easily moved from one location to another, whether by being lifted onto the trunk of a vehicle, placed on a shelf, or rolled. Try to find a lightweight air compressor that won’t tax your strength too much.
Pancake compressors, which are typically represented by designs that feature spherical air tanks with engines atop, are typically the most lightweight options, weighing in at around 30 pounds. Compressors with two tanks can increase capacity, but often weigh well over 70 pounds.
Wheeled options may be worth exploring for DIYers seeking for a high-volume compressor that can yet be moved around easily. They may be set up either vertically or horizontally and include wheels for portability.
Extra Features
To ensure long life and to maximize efficiency, air compressors might benefit from a few extra features. Compressors with built-in roll cages are encased in protective steel or aluminum frames. They are quite essential when portable compressors are in danger of being dropped from a truck’s tailgate.
Oil is used to lubricate the compressor pump in oil-cooled models. This keeps them cold, which increases their resilience to heat. Low-oil sensors, which turn off the machine if there isn’t enough oil, are sometimes included in these types to protect the compressor from premature failures caused by dry running and overheating.
Quick-connect adapters and simple petcock drain valves make it easy to remove any water buildup from inside a compressor.
Accessories
Sometimes, a set of extras will be included with your air compressor purchase. If you’re a DIYer but don’t have a garage full of air tools and accessories, this kit may be a good place to start. These kits typically include things like blow-off chucks, quick-connect fittings, and tire inflators.
Nail guns and air hoses are occasionally sold together in kits. There are kits available that contain all the parts and pieces needed to get started, thus reducing the amount of individual purchases required. If the air compressor you want to buy doesn’t come with the essential tools for setting it up, you can buy an accessory pack separately.
Types of Portable Air Compressors
Take the power source into account when you buy a portable air compressor. Electric or gas power is used by portable air compressors. Here we’ll go over the benefits and drawbacks of each different type of power source.
Electric
When it comes to portable air compressors, electricity is by far the most common power source. These devices have a motor that is powered by electricity and may be plugged into any ordinary socket. Electric motors have a long lifespan, require hardly any upkeep over the course of that lifespan, and are often quite lightweight.
Since most homes already have an electrical outlet available, portable electric air compressors are a practical solution for DIY workshops and home improvement projects. Since they do not produce any exhaust, they can be used safely inside without the risk of carbon monoxide poisoning.
But there are some drawbacks to electric compressors that you should be aware of. Service is frequently not an option because it would be more cost-effective to just replace the compressor with a new one. They are also not practical for use on construction sites that have not yet entered the electric phase unless a large-scale generator is present.
Gas
Portable gas-powered air compressors have internal combustion engines that pressurize the air storage tanks. The gasoline engine manufacturer has a significant impact on their overall quality. As long as there is gas in the tank, gas-powered compressors can be used almost everywhere.
They are more powerful than electric models, but their weight makes them less convenient to transport. Additionally, they have a higher maintenance cost due to the fact that they need to be winterized, have their oil checked occasionally, and have their fuel filter and spark plugs replaced every once in a while. Portable air compressors that run on gas are suitable for use on outdoor work sites and other areas without electricity, but they should never be used indoors because of the danger of carbon monoxide intoxication.
How We Chose Our Top Picks
We looked at the available models’ mobility, power, professional capabilities, and our hands-on testing experience to determine the best air compressors. Since most air tools only work with pressures between 40 and 90 psi, it was necessary for each electric compressor to come with an oil-free pump and create air pressure between 90 and 165 psi to be taken into account. We also sought for a selection of tank sizes to accommodate a wide range of equipment and projects.
FAQs
What is a portable air compressor?
Because of its mobility, a portable air compressor is useful in a variety of settings, including construction and home maintenance. Air can be sucked in, compressed, stored, and then released from this device so that a pneumatic power tool can be used, a tire can be filled, or debris can be blown away.
How is a portable air compressor used?
Plug an electric compressor into an electrical outlet, then turn on the power switch. When the compressor reaches the desired pressure, a pressure regulator can be used to modify the outlet pressure to meet the needs of a specific tool.
It’s important to make sure gasoline-powered compressors have oil in the engine and that the tank is full of gas. You need to turn the key to the “on” position and pull the pull-start cable until it begins.
How do portable air compressors function?
Portable air compressors have motors that drive pistons. The piston sucks in fresh air from the environment and forces it into the storage tank. It keeps doing this until there’s enough pressure to use tools or fill tires.
How big of an air compressor do I need for my garage?
Air compressors come in a wide range of sizes, and the one you need will depend on its intended purpose. People who intend to conduct substantial home improvement tasks would be well served by a tank sized between 15 and 30 gallons. For large-scale operations like cabinet and trim installation, painting, and more, a more powerful air compressor is necessary.
Final Thoughts
In conclusion, the portability of an air compressor is affected by a number of elements. To be really portable, an air compressor needs to be lightweight, well-built, and simple to move from place to place. What you intend to do with your portable air compressor will determine which one is ideal. A smaller, less powerful, but more portable air compressor will suffice for smaller tasks. Power and performance are more important than portability when dealing with massive workloads.
