7 Best Portable Air Compressors In 2018 – Ultimate Buying Guide

Portable air compressors are the fundamental equipment for many household and professional works.

In its essence, air compressors supply a huge amount of compressed air to do all sorts of jobs. Compressed air can be used to inflate tires, clean electronics, and power all kinds of air tools.

Best Air Compressors

In this buying guide, we will discuss all the ins and outs of portable air compressors, as well as our product recommendations.

Without further ado, let us begin by discussing the different types of air compressors.

Different Types of Air Compressor

We can generally divide portable air compressors into four major types. An important thing to note is that the different types won’t necessarily mean differences in performance. Instead, it will mostly affect practicality, portability, and tank capacity.

Pancake Air CompressorsHot Dog Air CompressorsWheelbarrow Air CompressorsTwin Stack Air Compressor

As the name suggests, pancake compressors are identified with the low-profile, pancake-shaped tank. They are typically small in size and lightweight with 1 to 6 gallons of volume.

Besides its small stature and overall portability, another unique value of pancake compressors is that they require very little to no maintenance. They don’t feature any belts, and the pump is oil-free. However, they lack the air capacity to run large air tools.

Again, the name ‘hot dog’ was derived from the cylindrical, hot-dog shaped air tank.

Hot dog compressors are very popular because they give you the balance between portability and air capacity: they are powerful enough to power small to medium air tools but still retains portability.

They are slightly heavier than pancake air compressors and noisier. If you are planning to purchase a hot dog air compressor, make sure to choose the ones with carrying handle for easier mobility.

Wheelbarrow air compressors have two tanks, which are positioned along the length of the compressor. Sometimes, the tanks are positioned along the width, and we call this type ‘pontoon’ air compressors.

With two tanks, obviously, they are heavier than the two types discussed above and have more air capacity. They can still be defined as portable, although the weight can exceed 70 pounds.

In many ways similar to wheelbarrow and pontoon air compressors, with the main difference being the position of the two tanks. With the twin stack type, the tanks are stacked beside the compressor unit.

Important Features To Consider In An Air Compressor

There are several important features you should consider before buying an air compressor. Depending on your needs, you can determine which product to get by examining these features.

Tank Size VS Portability

In an ideal product, you would want to have an air compressor that is as portable as it can get, and as powerful as possible.

However, that certainly is not possible, as the bigger the tank size is, the heavier the air compressor will be.

So, the important thing here is to figure out your needs. What do you need the air compressor for? If you need it to power medium to heavy-duty air tools, you will need bigger tanks. How much portability do you need? Consider the balance between those two according to your needs.

Noise Level

Generally, the bigger the air tank is, the noisier the air compressor will be, although that is not always the case.

Also, an air compressor with a low-noise technology in any forms will usually be more expensive. So, consider whether you need your compressor to be low-noise.

Oil-Free Pump

If the pump is oil-free, the air compressor will be easier to maintain. Also, compressors without any belts are easier to maintain. If you are planning to use the compressor for household usage, consider easy maintenance as your top priority.

Thermal Overload Protection

Thermal overload is the most common failure with compressors and any other HVAC (heat, ventilation, and air conditioning) appliances. Thermal overheating can cause the circuits inside the air compressor to fail, as well as fire damage in some cases. So, some form of protection is necessary.

Usually, thermal overload protection system works by opening the electrical circuit while overheating occurs. This way, electrical failure can be avoided.

Included Accessories

Different products offer different included accessories in the package. Some offer carrying handles for easier mobility, some offer spare parts, etc.  Before purchasing your air compressor, make sure to look at what’s included in the package.

Other Specifications

There are other features you might want consider. For example, the overall power of the air compressor is described on its horsepower rating. Operating pressure (PSI) will be useful if you are using the air compressor to power some air tools, as the tools will have PSI requirements.

CFM (Cubic Feet per Minute) rating determines how much air the compressor can put out in one minute, which will be related to its pressure (PSI).  When the CFM goes up, generally the PSI goes down.

Consider these specifications and other features based on your needs, which air tools will you use, and how often will you use the compressor. Also, the balance between price tag and its overall value is important.
