Air compressors for car have many uses in automotive AC systems, tires, engines, automotive painting and car detailing industries. Kotech compressor will discuss the top 5 air compressors for car.

AC air compressor for car

Car AC air compressor is the heart of the car air conditioning and refrigeration system, which plays the role of compressing and transporting refrigerant.

On the basis of the different air compressor parts and working modes, AC compressors generally include rotary AC compressors and reciprocating AC compressors.

Common rotary air conditioner compressors include scroll AC compressors and rotary vane AC compressors, and common reciprocating piston air conditioning compressors include crankshaft piston AC compressors and axial piston AC compressors.

Scroll AC compressor for car

The working parts of the scroll air compressor are two scroll disks. The geometry of the scrolls are involute Archimedean spiral. One of the scrolls is fixed and the other orbits eccentrically.

Scroll AC compressors for car have many advantages. For example, the compressor is small in size, light in weight, reliable in operation, and the most important, its operation is very quiet. Multiple compression chambers work at the same time, with small air pressure difference between adjacent compression chambers and little air leaks, the volumetric efficiency of scroll compressor is very high.

Scroll AC compressors for car are increasingly widely used in the field of small refrigeration due to their compact structure, high efficiency and energy saving, micro-vibration and low noise, and working reliability. Therefore, scroll compressors have become one of the main directions for the future development of compressor technology.

Rotary vane AC compressor for car

The vanes on the rotor of a rotary vane AC compressor divide the cylinder into several spaces. When the main shaft drives the rotor to rotate one circle, the volume of these spaces changes continuously, and the refrigerant vapor also changes in volume and temperature in these spaces.

Since the size and weight of the rotary vane AC compressor can be very small, it is easy to arrange in a small engine compartment. In addition, it has the advantages of low noise and vibration and high volumetric efficiency, and has also been used in automotive air conditioning systems.

Crankshaft piston AC compressor for car

When the crankshaft rotates, the connecting rod drives the piston to reciprocate, and the working volume composed of the inner wall of the cylinder, the cylinder head and the top surface of the piston will change periodically, thereby playing the role of compressing and transporting refrigerant in the refrigeration system.

(Crankshaft of piston compressor for car)

Crankshaft piston AC compressor is widely used, with mature manufacturing technology, simple structure, low requirements for processing materials and processing technology, and low cost. It has strong adaptability, can adapt to a wide range of pressure and cooling capacity requirements, and has strong maintainability.

Axial piston AC compressor for car

Axial piston AC compressor is the mainstream product in car AC air compressor. Each cylinder is arranged around the main shaft of AC compressor, and the piston movement direction is parallel to the main shaft of AC compressor.

Axial piston AC compressor is relatively easy to achieve miniaturization and lightness, and can achieve high speed operation. It has compact structure, high efficiency and reliable performance. After realizing variable displacement control, it is widely used in car air conditioners.

Air compressor for car turbocharger

A turbocharged engine refers to an engine equipped with a turbocharger. A car turbocharger is actually an air compressor for car that increases the engine intake volume by compressing air.

A car turbo air compressor uses the inertial force of the exhaust gas discharged by the engine to drive the turbine in the turbine chamber, and the turbine drives the coaxial impeller, which presses the air sent from the air filter pipe to pressurize it into the cylinder.

The working principle of a turbocharger is that when the engine speed increases, the exhaust gas discharge speed drives the turbine speed to increase synchronously, and the impeller compresses more air into the cylinder to increase the engine intake volume.

The increase in air pressure and density can make the car fuel burn more fully, increase the fuel amount and adjust the engine speed accordingly, thereby increasing the engine’s output power and torque.

The earliest car turbo air compressor was used in sports cars or formula cars, in those racing competitions where the engine displacement is limited, the turbocharged air compressor for car can bring more power to it to help win the game.

Air compressor for car tires

With the booming development of the electric vehicle industry, in order to minimize weight, most electric vehicles are not equipped with spare tires. Therefore, a small and lightweight tire air compressor is a product that meets current needs. It can not only provide emergency tire inflation function, but also greatly reduce the weight of the vehicle load.

The common working pressure of air compressors is about 8 bar, and it is equipped with a pressure regulating valve, which can flexibly adjust the inflation pressure according to the actual pressure requirements of the tire. Therefore, portable air compressors can surely be used to inflate car tires.

Most car air compressors for tires on the market are reciprocating piston air compressors, rotary vane air compressors or rotary screw air compressors, while centrifugal compressors are more used in large industrial fields.

As a common inflation tool, portable air compressors are widely used in tire inflation of various vehicles. Whether it is a small bicycle tire or a large vehicle tire, a portable air compressor can provide sufficient inflation capacity.

With a maximum pressure of 1.5 Mpa, it can also perform various blowing, spraying, purging and other tasks. It is one of the best air compressors for tires.

Air compressor for car painting

In the field of automotive painting, in addition to the selection of spray guns and the properties of paint, the influence of air compressor on automotive painting products cannot be ignored.

For different spraying needs, choosing the best air compressor for car painting will significantly improve the quality and process level of painting.

For spraying operations that require frequent movement, a portable air compressor for car that integrated with an air compressor tank is an ideal choice. It is small in size, easy to carry, and is well enough to cope with small-area automotive painting works.

For large-area spraying operations, an oil-free portable air compressor is a better choice. It has a large spray pressure, sufficient air supply, and stable air pressure. Although it may be a little larger and expensive, it can significantly improve the efficiency and quality of automotive painting.

When choosing an air compressor for car painting, be sure to pay attention to key parameters such as power, air output, and noise, and weigh them according to actual operation needs. At the same time, perform regular maintenance on the air compressor filters to ensure clean air output and good quality of automotive painting.
