Types of Portable Air Compressor

The major point of differentiation between the portable air compressors available in the market is whether they have a tank or not. If they are not equipped with a tank, then these are specially manufactured for tire inflation and deflation.

Tank Air Compressor 

These air compressors are more of a pancake style which typically resembles a garage air compressor. It provides a large amount of compressed air as compared to an air compressor without a tank.

Having an air compressor with a tank means that it has a higher capacity of holding compressed air up to a level of 6 gallons of specific volume.

This is extremely crucial if you are operating your pneumatic tools such as air drills that require a continuous supply of compressed air that a tankless or smaller air compressor cannot manage up to the mark.

However, these air compressors are slightly bulky which renders them a little bit difficult to be moved from one location to another thus affecting their portability.

Tankless Air Compressor

Tankless air compressors have shed a tremendous amount of bulk and weight perfectly enabled for easy movement from place to place. So if portability is your choice in product, then this air compressor fulfills your eligibility criteria.

However, a tankless air compressor cannot take the challenge of delivering sufficient amounts of compressed air to your tool.

This type of air compressor is suitable where a small burst of air is required such as inflation of tire and nailing and framing guns. Large pneumatic tools cannot be operated smoothly using tankless air compressors.

Power Sources of Portable Air Compressor

The portability of an air compressor is directly dependent upon the type of power source it is consuming.

Operating a portable air compressor with AC power could bother you to carry the generator as well as an air compressor to the work field that comes out very bulky and difficult.

Most portable air compressors function on AC power, extension wire from inside your home, or through a connection with a generator.

On the contrary, battery-operated air compressors are a level less efficient than AC power operated air compressors. They have limited delivery of power and compressed air to your pneumatic tool with a fear of running out sometimes.

However, they are rated at a higher degree for their portability as they don’t require a generator to run them in the work field.

At times of inflation and deflation in car tires, these air compressors can be directly plugged into the outlet of car batteries thus strengthening from DC power.

 Benefits of Portable Air Compressor | 2021 Reviews

Stationary air compressors can serve your purpose the same way as portable air compressors. However, there are some aspects in which the portable ones excel the stationary to provide additional benefits. Some of those aspects are worth mentioning.

1. Portability

This is the top tier and elite advantage of a portable air compressor. The operator is no more confined to the location of an air compressor. The portable unit can be moved easily from one site to another for purposeful applications.

These air compressors are therefore rated with outstanding efficiency for a large number of industrial tools. They are easily carried from one location to another as compared to those with heavy stationary design.

2. Compact Size

The portable air compressors are available in various sizes in the market. Most of these portable units are light in weight and small in size in contrast to standard stationary air compressors. Due to their size and weight, they can easily be adjusted within a limited space such as the corner of a garage or a workshop.

3. Low Level of Noise

Portable air compressors are way quiet when it comes to noise production as compared to loud stationary units. Due to high levels of noise production, stationary air compressors are not usually favored for indoor uses. Instead, portable air compressors are the most demanded due to minimum noise production both indoors as well as for commercial use.

Buying Guide For the Best Portable Air Compressors of 2021

Selecting the best portable air compressor while not having adequate information about the desired product can be unsettling and confusing.

Here we provide you with a detailed structure of all important aspects you can look for in your portable air compressor.

1. PSI and CFM

These are the important metrics for measuring the efficiency of any air compressor.

Pressure per square inch PSI gives you the measure of pressurized air whereas cubic feet per minute CFM measures the output of power.

It is crucial to know the values of CFM and PSI since the ill-matching of these values to your pneumatic tools can destroy both. Selecting an air compressor with a high value of PSI can be beneficial for a large variety of purposes.

Usually, the value of CFM of any portable air compressor is taken with reference to 90 PSI.

Any tool that requires short bursts of air such as inflating tires and nailing and framing guns need 2 CFM at 90 PSI.

For high power tools such as ratcheting and air drills, air at 2.5 CFM flow rate is required to operate without interruption. 

2. Motor of Portable Air Compressor

Another vital consideration in judging the performance of a portable air compressor is the motor.

Most pancake-style large portable air compressors utilize a powerful 120V motor that can even function without influence in extreme cold conditions and has the ability to compress large volumes of air in a limited period of time.

For small bursts of air such as tire inflation, smaller size motors can work efficiently with the caution of how much time it will take to inflate tires without running short of power.

3. Power Draw

Portable air compressors utilize 12-volt power sockets of your vehicle for their function.

This means that your car battery can be sufficient for powering portable air compressors to inflate and deflate tires.

The optimal range of power of a portable air compressor is 120 Watts to 150 Watts.

4. Size of a Portable Air Compressor

As the name suggests, portable air compressors are specially designed for easy movement from one site to another. This intends to make portable air compressors small in size and light in weight to make them ideal for on the go purpose.

The smaller and compact your portable air compressor, the more it will be convenient for you to fit it in the trunk of your vehicle and take it on the worksite.

5. Cord Length 

You need to connect a portable air compressor with a 12-volt power socket of your car, it requires a cord length that reaches all the four tires. In short, the cord should be long enough for ease of use. Some of the portable air compressors have 10 feet long power cord, others may be available in a longer length of 15 feet power cord.

15 feet power cord length is more in practice as it can be used over an extensive range of purposes without any trouble.

6. Warranty and Durability 

A wise selection of portable air compressor is a significant investment that gives you the product with no fear of wear and tear.

Air compressors that have metal parts in their making such as tank, fitting, and regulators are at a lower risk of getting damaged, thus giving you a long life out of a portable air compressor.

Do consider the rubber feet and powerful handles of a portable air compressor as they are the only means of movement whenever you carry it by hand.

Before investment on any portable air compressor, make sure that the manufacturers claim at least a 1.5 years warranty with a policy of return and exchange of any torn or damaged part within the mentioned time.

Conclusion

A portable air compressor is a prime investment for your indoor as well as outdoor purposes. They are light in weight, small in size, and produce negligible noise pollution. They are highly rated for inflating flat tires ensuring the best performance from your car.

Depending upon your budget, the smaller portable unit can be used for low air burst activities like an inflation of tires and nailing and framing. A mid-priced air compressor can offer you a powerful unit with multiple features assisting your high power pneumatic tools or an industrial spec for a costly price tag.
