Things to Consider Before Buying a 120 Volt Portable Air Compressor

Our air compressor buying guide will summarize the most basic knowledge you need to make a wise buying decision.

Type

Stationary Compressors

This type is often used by professionals and skilled workers and is a perfect device for plants and garages.

Most of this kind have an engine that generates from 4-10 HP to blow up even heavy truck tires. Being a professional-grade tool, it has a large tank, from 60 to 80 gallons, even up to 120 gallons, to work for a long time without recharging.

Stationary compressor

Normally, this stuff is securely locked on the floor and hardwired to the power source. Thanks to its vertical design, it significantly reduces floor space and facilitates use.

Portable Compressors

With many sizes and shapes, portable air compressors have become a more and more popular device on the market today.

Not as bulky as a stationary air compressor, this unit has a smaller container, around 2-6 or 20-30 gallons. The price of this product is also cheaper, and it is suitable for small offices and factories.

In terms of design, as the name suggests, it has a compact shape to move from place to place with handgrips and/or rollers.

Inflators

Technically, the inflator is a movable air compressor that is the smallest in size and excludes a reservoir. Therefore, you must plug in the power continuously while working to provide adequate air.

Inflator

This device is suitable for individual users and households. Inflators are very useful for blowing up tires, sports equipment, pool toys, etc.

Power Rating

Horsepower 

Horsepower specifies the capacity of the motor. If you are looking to buy an industrial air compressor, based on horsepower to evaluate its power is quite accurate.

But for small consumer-grade air compressors, the horsepower rating for engine power can be inaccurate.

If a consumer-grade air compressor is rated to have a 5 HP engine and can connect to a standard wall socket, remember that this machine can only deliver about 2 HP.

Normally, air compressors usually reach 1.5 - 6.5 horsepower.

However, especially for small air compressors for consumption purposes, you need to rely on SCFM (Standard Cubic Feet per Minute) criteria to more accurately assess the power of the machine and how much power this device provides for your stuff.

Pounds Per Square Inch

Pounds per square inch or PSI is to measure the air mass pressure that the air compressor produces in the tank. An air compressor needs a minimum of 90 PSI to work.

However, now on the market, there are many stronger devices with the ability to generate 120 – 150 PSI or even higher.

Note that an air compressor will need greater turn-off pressure to operate at a minimum of 90 PSI. That is why many industrial air compressors are designed with two stages.

Standard Cubic Feet Per Minute

To compare the power of an air compressor with the specification of the inflated items, you need to pay attention to the Standard cubic feet per minute, also known as SCFM, or CFM (cubic feet per minute).

SCFM is the total of air that an air compressor can deliver under standard conditions. Different tools and objects ask for a definite air mass, so the SCFM level is very important in assessing the quality of an air compressor.

Small items typically require 5 SCFM as a maximum, while large items may need over 10 SCFM. In fact, the air pressure inside the device can affect the distributed SCFM, so when comparing the SCFM of the device, it should be placed in correlation with the PSI criterion.

Pump Type

Single-Stage Vs. Two-Stage

Single-stage pump

The single-stage type has more than one cylinder that pumps air into its reservoir at a similar pressure. This type is suitable for household and easy-duty applications.

They will start at about 100 PSI and shut off when reaching 125-135 PSI.

Meanwhile, the two-stage type has more than two cylinders, where the first one will push air into the other cylinder(s). In stage one, the pressure level reaches 90 PSI and increases to more than 170 PSI in stage two.

In general, two-stage air compressors are usually designed for industrial compressors for equipment requiring high pressure.

Oil-greased Vs. Oil-Free Compressors

Oil-greased air compressors require oil to lubricate all interior parts of the pump for smooth operation. For the same size, oil-greased type is usually heavier and bulkier than oil-free units.

When using this type, you need to routinely check the oil volume and, if necessary, fill it up to avoid erosion and destruction to the parts.

Oil-free compressors are more popular than the former because they are maintenance-free. The reason is that they are covered with the same material that is put on anti-stick pans.

Oil-free types work efficiently for a variety of applications. Smaller in size and lighter than oil-greased compressors, it is more convenient to move from place to place.

Direct Drive Vs. Belt Drive Compressors

Direct drive devices have the equal speed as the engine since it connects to the drive shaft directly. Most direct drive units have low RPM and normally spin at around 1,700 - 3,450 RPM.

There are several oil-free direct drive compressors, but their quality is not as expected. To get the job done, you can purchase an oil-lubricated belt drive compressor, although it is quite bulky and immobile.

Drive compressor

Belt drive devices are more effective than direct drive compressors because their pump can rotate much more gradually than the drive. Thereby, they can perform well for longer durations with less damage.

To use this type for a long time, you need to keep the oil at the suggested degree to reduce the amount of heat moved from its pump to the engine and reduce engine vibration.

Frequently Asked Questions

How Long Should I Expect My Tire Inflator To Last?

There is no specific number on the life of a tire inflator; it depends on how well you maintain it. The more often you maintain your machines, the longer they will last.

To prolong the life of a tire inflator, you need to do the following: first, check the oil level, make sure the parts are adequately lubricated.

Second, check, clean, and replace the filter every week to avoid debris and dirt from damaging the tire inflator.

Third, monitor the temperature, avoid it becoming too hot, causing the equipment to wear out.

Fourth, tighten the loose bolts when you see the device vibrate and make a loud sound. Doing this will keep the machine in good shape and avoid any arising problems.

Fifth, follow the instructions when something goes wrong by reading the operating manual or contact a reputable service provider for help.

What PSI Are Most Standard Tires At?

Standard PSI tire is important to the user's protection and the longevity of your vehicle. Not fully inflated tires can burn and scratch unevenly, and over-inflated ones can explode.

For most vehicles, you can find standard tire pressure information on the label/tag inside the driver's door or in the owner's manual. In general, standard tire pressures typically range from 32-40 PSI in cool condition.

Therefore, you should check the tire pressure before starting the car early in the morning or wait at least three hours after driving. You can check tire pressure at professional auto repair shops or use a pressure gauge by yourself.

What Is The Benefit To Owning A Portable Air Compressor?

Owning a portable air compressor offers many benefits. First, they are handy and portable thanks to their small size and lightweight, so you can use them flexibly at home or on-the-go with your car.

Second, they save time and money. There are many portable air compressors at reasonable prices that are suitable for household use on the market today.

With good maintenance, an air compressor will stay with your family for many years. It is so easy to inflate a lot of household items on-site in just a few minutes.

Third, they are multi-purposes. You can inflate tires, floats, and balls; finish nails with a single portable air compressor and the right tools.

What Are The Benefits Of Keeping Your Tires Fully Inflated?

Keeping your tires fully inflated has more benefits than you think.

First of all, driving with under-inflated tires causes them to fatigue sooner because some tire parts have to bear extreme weight, leading to damage. Plus, you'll save money on gas by running on fully inflated tires.

Not only that, small tire pressure lays tightness on your vehicle’s engine since it needs more energy than usual. This fact leads to more harmful gases being released into the environment.

Last but not least, underinflated tires will not grip the road, which means it will take longer than necessary to force your car  to a full stop.

Under-inflated tires run the risk of slipping in wet conditions or cause a tire blowout. So keep your tires fully inflated, for your own safety, the longevity of your vehicle, and a clean environment!

Conclusion

With the useful information we provided in this post, you will not only gain useful basic knowledge about air compressors but also easily find the best 120V tire inflator that suits your needs and budget!
