Despite the fact that all types of automotive compressors have the same purpose, they differ as possible exploitation and efficiency. That is, the power compressor for passenger cars is absolutely not suitable for applying cargo transport. This adaptation has differences even between vehicle classes, for example, between a conventional sedan and an SUV. Therefore, when choosing a car compressor should be very attentive. About this further in the article.

Autocompressor for tire swaps, what type they are, the advantages and disadvantages of piston and membrane autocompressors

Automotive compressors are divided into piston and membrane. In compressors, where the membrane is used, the air is injected with reciprocating movements, which makes a rubber membrane located on the piston. The cost of automotive compressors, where the membrane is used is quite low, which is the main advantage of these devices. However, such compressors lose piston mechanisms in speed and maximum pressure. In addition, this type of compressors changes its behavior in low temperatures, since the rubber membrane becomes fragile, solid and loses its elastic properties that entails the output of the equipment.

Most of the implemented and manufactured compressors are piston. The pressure in them is created using a moved piston. The most best of itself has established a design where a metal rod of the piston is mounted on the shaft of the electric motor, without the use of additional plastic bushings, various connecting rods and adapters. The life of these automotive compressors is the largest. It is worth noting that the use of the Teflon Ring on the piston also increases the terms of operation of automotive compressors.

Characteristics of autocompressors for tire swaps, which we draw attention when choosing an aggregate

There are a number of basic characteristics to pay attention to when choosing a car compressor:

1. Performance.
2. Purchase pressure.
3. Type and availability of pressure gauge.
4. Connection method.
5. Pitch the scale of the pressure gauge and its graduation.
6. Cord length.
7. Built-in modern gadgets.
8. Set of adapters.
9. Reliability of the device.
10. Price.

compressor performance

This parameter is measured in liters per minute. Therefore, when choosing a device, it should take into account its landing diameter of tires and performance. For example, for 14-inch tires, there is enough device with rates of 40 liters per minute. For larger tires, it is desirable to purchase a device that can be hampered up to seventy liters. In addition, manufacturers do not rarely indicate the numbers of volume, without refinement, this volume is either under pressure. The first indicator is usually applied, so this aspect must be clarified by the seller.

purchase pressure

When choosing a automotive compressor, many car owners prefer compressors with a maximum pressure indicator, but this is not always correct. The problem is that most manufacturers overestim (sometimes very significantly) characteristics of their products. So, on some devices the pressure is indicated 20 atmospheres, but it is simply unrealistic. The present limit is eight atmospheres. As for passenger cars, there are enough atmospheres for them.

availability and type of pressure gauge

The type of pressure gauge is digital and shooting. Accuracy in this case is the determining indicator. Consequently, the error of the device must be minimal. There are a number of classes of pressure gauges depending on the error: 0.2; 0.6; 1.2; 2.5; 4. The best will be the device with the lowest number. As for accuracy, it is desirable to purchase a compressor with a digital manometer. Why? Because when pumping the wheels, the device constantly vibrates, which entails the jumps of the arrow on the analog screen. In addition, the presence of two scales on the arrow pressure gauge make the scoreboard with overloaded data and make it difficult to read.

Digital manometers issue information in a predetermined indicator with maximum accuracy. In addition, the vibration is simply missing. Another advantage of electronics is the ability to limit the required pressure (for example, two atmospheres). The compressor will turn off when the wheel is pumped.

connection method

In this regard, car compressors have two variations:

1. Which work from the automotive network.
2. Which work from the built-in battery.

Compressors that work from the built-in battery can be charged from a simple outlet, but their charge is not enough for a long time - you can pump two or three wheels, but then you will have to regret again. Of course, electrical compressors are preferable. Such devices can be connected to the cigarette lighter either to the battery (using wires with clamps, which are dressed on terminals). Compressors that are connected to the battery are greater power, so their acquisition looks more appropriate.

conditioning of the scale of the pressure gauge and its step

Try to choose manometers that do not have progenic pressure values. Give preference to pressure makers with a division price 0.1 atmospheres. By the way, after the acquisition, check its testimony by comparing the posts after pumped to a hundred.

length of cord

The length of the cord must be like that you freely get to all the wheels of the car. There are models with a built-in battery, when purchasing which it is not at all necessary to think about it, but in this case it is necessary to understand how long the battery charge will be enough, and do not forget about its loss of tanks with time.

availability of built-in modern gadgets

Many devices can be applied not only to pump the wheels, besides, it is not always necessary to pump it completely. Many functions may be much more in demand than it seems when purchasing. Automotive compressors can be equipped with the following options:

1. Disconnection - This option is triggered or when the wheel is swollen to a certain extent, or when the device is overheating, if it is equipped with a special thermorel.
   
2. Air pumping - this will help the owner in those situations where you need to turn the inflatable mattress or the like inventory.
3. Air blending - a special valve is responsible for this feature.
4. Flashlight - Built-in flashlights are the most common, which is especially useful at night.

set of adapters

When purchasing a car compressor, pay attention to the presence of various adapters that will give you the opportunity to pump a variety of rubber products - toys, boats, mattresses, balls, up to the transformation of the car compressor in the vacuum cleaner.

the reliability of the device (from which metal is made of a cylinder, is there an air filter, as the piston connecting rod)

To make sure that the purchased device is quite reliable, pay attention to its design features that are specified in the technical support:

1. What metal made a cylinder. The best option is high-alloy steel, the optimal option is the stainless steel, the cheapest option is alloys with aluminum.
2. Installing a piston connecting rod. Reliable option - on a metallic shaft, the worst option - through plastic bushings and adapters.
3. The presence of a air filter on the intake opening of the auto compressor.

price

If we talk about the cost of compressors for tires, prices from 300 rubles vary. For Chinese products of dubious quality and up to 1000-1500 rubles. For a normal device. It is not recommended to buy the cheapest product, because its quality leaves much to be desired. They may well lend the owner at the most inappropriate moment, for example, when the wheel has lowered, but there is no tireage nearby.

It is advisable to purchase a normal compressor from 1000 rubles. The body of such a product is made of steel, in contrast to Chinese plastic. As a rule, the kit includes additional nozzles, for example, to pump down the balls for football.

In addition, a cheap Chinese automotive compressor will pump a completely lowered wheel from five to ten minutes, and normal - two or three minutes. As you can see, the difference in time is significant.
