Many of us use our car to commute to work/school. The machine saves a lot of time. But if a flat tire, it's for a long time. You can solve the problem - use compressors to inflate car tires. They will create working pressure in the tire in a couple of minutes. And even if you have a small puncture, you can easily get to the tire shop without a tow truck. Let's look at what characteristics this device should have and how to choose the right one. Auto-air compressors for tire inflation today are one of the integral accessories in the car. It is with the help of these devices that you can easily fix a broken or flat tire on the road. This is a very useful item.
Main specifications of autocompressors
In fact, there are few characteristics, but they must be taken into account. If you choose the device incorrectly, then it simply will not be able to pump up a particular wheel on a particular car. The most important characteristics are performance, maximum and working pressure, the presence or absence of a pressure gauge.
Performance
Compressors for inflating car tires differ in power. This indicator is specified for each model and is measured in liters per minute. For example, if the label indicates a performance level of 30-40 l / min, then such a device will be able to inflate a tire by 13-14” in a car in a few minutes.
For off-road vehicles, as well as for crossovers, which differ in larger diameter wheels, it is recommended to choose equipment with more power. The recommended characteristic - from 50 l/min. Often, manufacturers do not provide information on how this performance indicator should be understood - this is the rate of filling a certain amount of air or a volume under pressure.
Pressure
Compressors for inflating car tires differ in this characteristic. So, the maximum working pressure indicators are up to 8 atm. However, when choosing, it is not recommended to build on this maximum value. In addition, the market often offers models that do not match the value declared by the manufacturer.
In stores you can find inexpensive equipment, where the passport data indicatesfigure in 20 atm. For portable devices (and these devices are portable), it is simply not realistic to create such pressure. Even KamAZ wheels have a peak pressure of 8 atm, and here as much as 20.
Manometer
Auto-air compressors for tire inflation can be equipped with a pointer or digital pressure gauge. 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 devices are equipped with sufficiently accurate measuring equipment with a minimum error. Its scale on devices of various price categories is well read and easy to use. Pressure gauges are divided among themselves according to accuracy classes. These are 0, 2, 0, 6, 1, 2, 2, 5, 4, 0. The smaller the class, the higher the accuracy of the measuring instrument.
Features of mechanical pressure gauges
On such a device, most often there are two scales for different units of measurement. So, there is a scale in pounds per inch squared, but there is one in atm. The scale is rated at 300 psi. Thus, the manufacturer creates the illusion of power - often, the units do not have such performance. 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 level of tire pressure with a separate pressure gauge. On these measuring instruments, the scale is more informative.
Digital gauges
These devices are more convenient and practical than analog devices. The pressure is measured with a highaccuracy. During operation, there is no image vibration, and you can also change the units of measurement. Another advantage is the presence of a start-stop system. The car owner sets the desired pressure on the scale and the device will simply turn off when this pressure is reached.
Differences in food type
Also, compressors for inflating car tires differ in the type of power supply.
They are mains powered and have more power. On sale there are units powered by a cigarette lighter. Their power is often small. There are also devices equipped with a battery.
Useful options
When choosing car compressors for tire inflation, it is necessary to pay attention not only to the performance or accuracy of the pressure gauge. Last but not least is the ease of use. After all, most often motorists pump up wheels, but rarely pump them up completely. A useful feature is the ability to evacuate air - sometimes it is necessary to evacuate air mattresses or boats. Also, the device can be equipped with a bleed valve. This allows you to most conveniently reduce the pressure in the tire. Another useful option is automatic shutdown in case of overheating.
Now both imported and domestic units are equipped with a large number of nozzles. Adapters help inflate not only car wheels, but also balls, boats, and other things that people use in everyday life. Boat nozzle forThe tire inflator will appeal to fishing enthusiasts.
Selection Tips
Professionals recommend purchasing a device with a metal case. 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 and other defects. As for the nozzle, experts advise the threaded option. Information for those who are going to purchase a tire inflation compressor: the price of these units is from 1300 rubles and more. There are domestic and imported models.
