Car pump or compressor - a thing that can be found in the trunk of each car. In order not to fear in the way of unpleasant situations with wheels, you must weighingly approach the selection of this desired accessory. Pumps are two types - mechanical and electric.
1
The mechanical pump is driven by foot or hands. Accordingly, its power and the rate of pumping the wheels depend on the physical force of the one who enjoys them. Foot mechanical pumps are more efficient and compact than manual. The advantages of such a device include ease of use, relatively low cost.
2
Electrical automotive compressors work from the cigarette lighter or from the battery. Air into the tire is supplied with a piston pump, which runs from the built-in motor design.
3
The electrical compressor is equipped with a pressure gauge, providing control and regulation of the degree of pumping of the tire. On more modern models, as a rule, there is a backlight of the display of the pressure gauge. Included there may be special nozzles for pumping boats, inflatable mattresses, wheels of bicycles.

For passenger cars, a fairly ordinary compressor with a capacity of up to 2 atmospheres and pumping speed to this volume from 3 to 5 minutes. The wheels of large SUVs and trucks are serviced using more efficient electric pumps capable of working for a long time. To avoid overheating during continuous operation, they are equipped with a cooling system. The maximum duration of this compressor is 30 minutes.
5
From the power of the compressor, the method of connecting it to the network depends. Only small electric pumps with power consumption of no more than 180 W can work from the cigarette lighter. For more efficient models, direct connection to the battery is required. In such compressors, separate containers of the cylindrical form for the piston and the engine are provided. It protects the apparatus from overheating and reduces the noise level in working condition.
6
The compressor can be equipped with a "auto stop" system, which allows you to set the maximum pressure required. Some expensive models also perform the functions of the automotive vacuum cleaner.
Modern models of autocompressors are easy to use, universal and necessary on the road to each driver.
