Compressors for pumping car tires. How to choose the right car compressor?

Many of us use the car to travel to work / study. The machine saves a lot of time. But if the wheel has lowered, it will be a long time. You can solve the problem - use compressors for pumping car tires. They will create working pressure in a tire in a couple of minutes. And even if you have a small puncture, you can quite reach the tire service without a tow truck. Let's consider what characteristics this device should possess and how to choose it correctly. Auto-air compressors for pumping tires today are one of the essential accessories in the car. It is with the help of these devices that you can easily repair a punctured or flat tire on the road. This is a very useful thing.

Main technical characteristics of car dealers

In fact, there are not many characteristics, but they must be taken into account. If you pick up the device incorrectly, then it simply will not be able to pump a specific wheel on a particular car. The most important characteristics are capacity, maximum and working pressure, presence or absence of a manometer.

Performance

Compressors for pumping car tires differ among themselves in power. This indicator is indicated for each model and is measured in liters per minute. For example, if the label indicates a level of productivity of 30-40 l / min, then such a device will be able to inflate the tire for 13-14 "in a few minutes on a car. For off-road vehicles, as well as for crossovers, which differ with wheels of larger diameter, it is recommended to choose equipment with greater capacity. The recommended characteristic is from 50 l / min. Often manufacturers do not provide information on how to understand this performance indicator - it is the rate of filling a certain amount of air or the volume under pressure.

Pressure

Compressors for pumping car tires differ in this characteristic. Thus, the maximum operating pressure values are up to 8 atm. However, when selecting, it is not recommended to repel this maximum value. In addition, the market often offers models that do not match the manufacturer's declared value. In the shops you can find inexpensive equipment, where the passport data indicate a figure of 20 atm. For portable devices (and these devices are portable), creating such a pressure is simply not realistic. Even the wheels of "KamAZ" have a peak pressure of 8 atm, and here as much as 20.

Manometer

Air compressors for pumping tires can be equipped with a dial gauge or a digital manometer. This is an important device. The accuracy of the pressure that will be pumped into the wheel is of great importance. Many domestic and imported instruments are equipped with sufficiently accurate measuring equipment with a minimum error. Scale it on devices of different price categories is easy to read and convenient to use. Manometers are divided among themselves by accuracy classes. This is 0.2, 0.6, 1.2, 2.5, 4.0. The smaller the class, the higher the accuracy of the measuring device.

Features of mechanical pressure gauges

On such a device, there are usually two scales for different units of measurement. So, there is a scale in pounds per inch in a square, and there is an atm. The scale is designed for 300 psi. Thus, the manufacturer creates the illusion of power - often, such a performance units do not. But the accuracy of such a scale is quite low even in the range from 2 to 2.5 atm. For your own peace of mind, it is better to control the tire pressure level with a separate manometer. On these measuring instruments, the scale is characterized by higher informativeness.

Digital pressure gauges

These devices are more convenient and practical, unlike analog ones. The pressure is measured with high accuracy. During operation, there is no vibration of the image, and units of measurement can also be changed. Another advantage is the availability of the "start-stop" system. The car owner sets the pressure on the scale and the device will simply turn off when this pressure is reached.

Differences by type of food

Also, compressors for pumping car tires vary in type of power. They can work from the network and have more power. On sale there are units that are powered by a cigarette lighter. Their power is often small. Also there are devices equipped with a battery.

Useful options

When choosing automobile compressors for pumping tires, it is necessary to pay attention not only to the capacity or accuracy of the manometer. Not the last is the convenience of use. After all, most motorists pump up the wheels, but they rarely pump them up completely. A useful function is the possibility of evacuation of air - sometimes it is necessary to evacuate air from inflatable mattresses or boats. The device can also be equipped with a bleed valve. This makes it possible to reduce the pressure in the tire as conveniently as possible. Another useful option - automatic shutdown when overheating. Now both imported and domestic units are equipped with a large number of baits. Adapters help pump not only the wheels of cars, but also balls, boats, as well as other things that people use in everyday life. Boat nozzle for the compressor for pumping tires will be to the liking of lovers of fishing.

Tips for choosing

Professionals recommend buying a device with a metal casing. This equipment has a longer service life. The plastic housing must withstand low temperatures. This also applies to connecting hoses. The length of the power cable must be at least three meters. It is best if the wire is as solid as possible - without cracks or other defects. As for the nozzle, experts advise the option with thread. Information for those who are going to buy a compressor for pumping tires: the price for these units is from 1300 rubles and above. There are models of domestic and imported production.
