Is a tire inflator an air compressor? | Drive

There is no best time for a puncture, only when it is worse or worse. This is bad when a tire near your home is flat and it takes time to fill or repair it. When it is on the side of a busy highway, the situation is even worse. But the worst time is when you don't have a temporary patch, your spare tire bursts, and you are far away from the air compressor. 

Inadequate preparation will cause more trouble, waste more time, and spend more money. One way to ensure that you always have at least a fully inflated spare tire is to place a portable tire inflator in your car. You can use it at any time to keep the tires at the specified optimal pressure, and you will develop a backup plan for the spare tire in case of emergency.

There are many different common names for these devices, including tire inflators, mini air compressors, and portable air compressors, which can be confusing when you consider that many people think of air compressors as large tanks located in the corner of the garage. So is it really an air compressor without a fuel tank? 

In order to eliminate this confusion, the Guides & Gear team decided to "turn on" a tire inflator and display all its contents in an easy-to-understand explainer. let us begin.

Tire inflators are different from simple air pumps; they are actually miniature air compressors. To better understand how they work, we broke down the main components that make up these devices and explained how they work together to inject air into tires.

The most common portable tire inflators will be plugged directly into the wall, plugged into the 12V cigarette lighter in the car, or use battery power. Each has its own advantages and disadvantages, but the type of plugging into the 12V port is the most common for the driver. 

A switch, whether in the form of a dial, a slider, a toggle switch, a trigger, or a button, can complete the power circuit of the device and turn on the device by engaging the motor. Essentially, a switch is how you turn the device on and off.

The internal electric motor is the power source of the tire inflator. The output shaft of the motor is mainly connected to a gear that transfers energy to the piston. However, in some cases, the output shaft is also connected to a fan, which rotates to cool the device while the motor is running.

Some tire inflators have built-in handles.

In most tire inflators, you have two gears, one connected to the motor and one connected to the piston. When the motor moves, it turns its gear, which is embedded in the gear of the piston. Therefore, when the motor moves, the gear moves the piston. In some cases, there may be a third gear to turn the fan. 

It's not exactly the same, but your gas-powered car does share one component type with the tire inflator: the piston. Although the motor drives the mechanism, the piston and the cylinder that houses it are where the action takes place. 

When the gear rotates, the piston is pulled down to bring air into the cylinder through the air inlet, and then pushed up. When the piston rises, the air is compressed and pushed through the tube connected to the tire. The piston steadily repeats this cycle to continue to compress air and pump it into the tire.

Most tire inflators will be air-cooled by a small fan built into the device. The location of the fan will vary, but it is likely to be close to or close to the motor that generates most of the heat.

If there is no valve working together, the piston will not be able to accomplish its purpose. The valve type, whether it is a ball valve, a flap valve, or other types, will be different, but they all have the same purpose: to draw air into the cylinder when needed, and to prevent air from entering when not needed.

Your tire inflator may also use pressure sensors. This can be used to read the pressure to display it on a digital meter, and/or they can be used to control the valve to close automatically. 

The connector or tube at the end of the tire inflator pairs the inflator with tires, balls, or anything else that needs to be inflated. It is usually made of rubber and sometimes covered with a fabric wrap. Many new models provide various tips that are paired with connectors for multiple purposes.

In short, you only need to flip a switch and the motor will turn on and drive the piston, which pressurizes through the connector and pumps air into the tire.

The coiled hose makes storage easier.

Technically speaking, yes, the portable 12V tire inflator is an air compressor. However, it does not have a tank to store compressed air, nor does it have the ability to provide power for pneumatic tools. Therefore, it is often called a tire inflator or simply an inflator because this is its only purpose and capability.

You have a question, the drive has an answer!

A. The motors in the tire inflator will heat up very quickly. If they are not sufficiently cooled, they will not be able to run for a long time. You will see that some of the most common run times are only about 5-10 minutes, but each inflator will be different. Check the user manual/service manual for detailed information about your machine.

A. There are always exceptions, but the vast majority will not. Most tire inflators you encounter, especially new ones, are oil-free.

A. To use pneumatic tools, you need an air compressor that can continuously generate a large amount of pressure and stable air flow for a long time. Small tire inflators cannot accomplish any of these things, so they cannot provide power for pneumatic tools.

A. Air compressors of different sizes are used for different tasks, so it depends on your goals, budget and the pneumatic tools you will use. For more detailed information, please visit our guide, how the garage air compressor works and the size you need, 

Answer: This is different for each car and tire, so you need to check the information posted on the inside of the driver's door or on the owner's manual. The tire itself usually displays the maximum tire pressure, but this is different from the recommended tire pressure.

Answer: First of all, if you don’t know, PSI stands for pounds per square inch, which is a measurement of air pressure. When your inflator is inserted into the tire, it will record a PSI on the built-in meter (if your device has a PSI). However, when the tire is in inflation, these readings will disappear. Therefore, make sure to measure when the inflator is turned off.

Now that we have explained what the tire inflator does and how it works, we want to show you the appearance of all the parts. In the video below, the demonstrator disassembled a cordless Ryobi device with some problems.
