Many motorists remember times when manual and foot pumps were used to swing the wheels. However, over time, compact car compressors came to their replacement, which became an integral part of the automotive set of any driver. The advantage of the machine compressor was obvious due to its compactness, reduction of physical exertion and pumping speed. With such a compressor, it became possible to quickly and without much difficulty, increase the tire pressure, pump the tire sliding, even if there is no car service or maintenance station nearby.

Types of automotive compressors

A huge selection of compressors in the car accessories market allows the motorist to make a choice on any requests.

The technical device of compressors is almost identical.

The mechanism consists of an electric motor, a cylinder for operation and a graduated scale of tire pressure measurement.

Currently, piston and membrane compressors for tires are divided.

piston compressors

Piston compressors have higher technical characteristics, they are much more powerful, pumping speed is significantly lower, it is possible at any time of the year.

However, they have a property to heat up during operation, and dust, fall into the piston system, leads to the rapid wear of the parts of the mechanism.

membrane compressors

Membrane compressors create a low pressure, which is enough to swipe most passenger cars, are convenient to operate in warmth time.

However, piston compressors remain the most common and purchased.

Technical characteristics of automotive compressors

When choosing a car compressor, attention should be paid to the main technical parameters:

- Pump performance. This important characteristic of the compressor is measured in liters per unit time (minute).

For most passenger cars, optimal tire pressure is a value of 2.5 - 3 atmosphere.

Therefore, it does not make sense to buy a compressor with a higher productivity, as this will lead to excessive financial costs. In addition, you can connect this less powerful unit to a conventional cigarette lighter or a 12 volt automotive electrical outlet.

For cars whose wheels have a large radius of the wheels, as a rule, more than R16, you will need a more productive compressor.

These cars include SUVs (jeeps), minivans, cargo vehicles.

The more powerful pump must be connected to the battery terminals.

A different connection is fraught with an overload of automotive electrical wiring and an electrician failure.

- Maximum tire pressure.

Knowing the technical characteristics of the car, including tire pressure parameters, you can choose the corresponding compressor.

The overestimated maximum pressure rate for most cars does not carry practical benefits, and the price of such a device is much higher.

This parameter is more pressing for heavy heavyweight cars with a large radius of wheels.

- Location of the rod of the piston.

More reliable compressors are those whose piston rod is connected directly to the electric motor shaft.

The presence of unauthorized plastic elements (adapters) significantly reduces the service life of the device, lowering its efficiency.

- the gradation of the compressor scale and its location.

When choosing a car pump, it is recommended to pay attention to the testation scale of the pressure gauge.

The optimal fission price of readings should be 0.1 atmosphere. It should be remembered that the smaller the graduation of the scale, the minimal error in the testimony.

Therefore, do not use a compressor with high pressure indicators (for example 15 atm.) To swapping a conventional car wheel (3 atm.).

The location of the compressor scale also has a certain meaning, when buying needs to pay attention to the convenience of readings.

- Method of connecting to the power grid.

For automotive compressors there are two connectivity: through the salon electrician (cigarette lighter or socket) or through the battery terminals.

The first method is designed for a device with low performance.

Connection to the battery is a more reliable method, this method is suitable for more powerful units.

Compressor indicators responsible for the convenience of operation

-Maximum length of the electric shower. It should be sufficient to swing all the wheels of the car. The use of a compressor with a battery leads to a rapid decrease in electric potential and discharge.

- the presence of a digital pressure indicator. The presence of such a scale creates convenience when reading information, reducing the error in determining the values \u200b\u200bof tire pressure.

- Additional built-in accessories for additional comfort when working. Such elements include special lighting devices (built-in flashlight) during operation, as well as automatic shutdown devices during overheating.

When choosing a compressor for a car, you need to pay all the indicated characteristics and parameters, and also remember that a cheap compressor with bad indicators can create many problems on the road.
