Best 12 Volt Air Compressor For Trucks - Buying Guide
Type
According to the structure of the air compressor, we have the following classifications:
-
Piston air compressor: This is the earliest type of air compressor among the available air compressors today. Equipment constructed with at least 1 piston. For 2-stage piston compressors possessing exceptionally high pressure, suitable for heavy industries.
-
Screw machine: This machine has a highly stable rating and high reliability. Compressed air will be from moving the 2 shafts towards each other. This equipment works with low noise, and there are 2 types of machines: oil-free and oil-free.
-
Convection compressor: The process of compressing the air of this device will go through the rotor system in the rotor. The pressure will gradually increase when the air enters the rotor and then moves through the propeller system. The advantage of this air compressor is in terms of exhaust airflow, so this product is suitable for jobs that require vast amounts of compressed air.
-
Centrifugal compressor: This compressor has a capacity that often reaches hundreds to thousands of bars.
-
Mixed flow compressor: This one is similar to a centrifugal compressor, but there is also an additional axial and radial speed mechanism at the rotor outlet.
Demand
Below we will provide users with some suggestions for buying an air compressor to suit the job requirements:
-
For household use: air compressors with a tank capacity of 10-30L are suitable for you. The use of oil or not will depend on the needs of your household work. This machine is ideal for use in jobs such as: blowing dry, inflating, spraying snow foam, nailing, spraying paint, and spraying dust. If you are looking for an air compressor device for your truck, check out the Gobege 12V Portable Air Compressor 5.65CFM.
-
For small-scale workshops: Medium pressure compressors are the first choice for you. If you want to increase productivity, you can choose models with high capacity.
-
For large-scale production units: Screw air compressors because of their extremely high pressure and ability to operate continuously are the machines that you need to find to ensure that they can meet the needs of your home.
Specifications
-
Power: This number represents the engine's ability to pump air. Therefore, for large-scale operations that need a fast and continuous intake of air, you should choose machines with large capacities and vice versa.
-
Compressed air pressure: This number shows how strong-weak the tight airflow is. The gas pressure is usually in the range of 8-10 kg/cm2 (bar). A few will be at 12 bars, 20 bars, etc. If you are looking for a device with stable air pressure suitable for your truck's needs, you can refer to the iKer Portable Air Compressor Heavy Duty.
-
Compressed air flow: These numbers determine compressed air intake and production capacity. The more air volume, the more suitable systems using large compressed air. Small car washes only need a type with an intake airflow of a few hundred liters per minute.
-
Container capacity: This number is similar to airflow; industrial machine systems need a large capacity tank to supply one or more machines and vice versa simultaneously.
Performance
Air compressors usually have a small capacity of less than 15 horsepower; they will often use the piston type and can constantly be cooled by the wind by the propeller, as well as use a capacity of 10-15 horsepower with many kinds using a box.
A product with outstanding performance and positive customer reviews that you cannot ignore is the GSPSCN Silver Tire Inflator.
Noise level
During operation, the engine of the machine rotates, and the process of exhaust gas of the device will cause noise. To reduce the impact on users, you should also choose low-noise models of Shark, Puma, and Hitachi.
An easy-to-use portable air compressor with maximum efficiency and low noise that you can refer to as the GSPSCN Portable Air Compressor.
Safety principles
Production origin
Choosing air compressors of reliable origin will help you buy high-quality machines from reputable brands that will save you money on device operating costs such as electricity consumption and maintenance costs.
Inspection papers
When buying an air compressor, you should ask the supplier to provide you with safety certificates offered by reputable organizations, which ensures that the air compressor you buy is of quality. About the thickness of the compressed air tank, the motor equipment is stable and safe.
Price
The price is often associated with the quality of the product. Many customers want cheap, so it is easy to be overtaken by units selling low-quality air compressors and buy fake goods for only ½ of the price of genuine air compressors.
However, after a short time of use, the machine generated many problems and failures, causing customers to spend a small amount of money on the repair and maintenance of the device. Therefore, choosing to buy a genuine air compressor is one of the ways to save money.
In addition, customers should also consult the prices of many different suppliers to choose to buy a simple machine at a reasonable price. You can immediately refer to the ALL-TOP Air Compressor Kit at an excellent and affordable price with stable performance.
Warranty
A genuine air compressor will always come with whole warranty policies and modes, ensuring customers' best interests.
If the machine has any errors during the warranty period, the customer can ultimately bring the device to the service center for free repair.
The warranty card of the genuine air compressor will have complete information such as the date of purchase, warranty period, warranty unit, warranty conditions, and red seal of the company.
Units that provide fake, counterfeit, and poor-quality machines will not have a warranty card or the warranty period is usually very short.
Usually, the warranty period of a device lasts from 6 to 18 months, depending on the manufacturer. It is one of the factors that help you choose a quality air compressor.
FAQs
What should be paid attention to when installing?
After the selection to buy an air compressor has been completed. Based on user requirements, you can choose mobile and fixed machines.
-
Portable compressor: Small in size, using two or four wheels for easy movement, suitable for production operations.
-
Fixed compressor: Due to its large volume and weight, it is unsuitable for moving. In addition, this type of air compressor is permanently installed due to the requirement of fixed installation and the reduction of vibration and noise. However, users need to pay attention to the strength and degree of fixation when installing.
Do I need to buy any additional accessories?
It all depends on what you want to do with the compressor. Of course, you will need an air chuck; to inflate the tires, you will need some tire chuck.
How to solve engine overheating?
First, in hot weather like summer, when we encounter this problem, we should check if the temperature in the air compressor room is too high or not.
Because of the high-temperature background in the summer, the hot air coming out of the air compressor, if not handled properly, will cause the hot air to return to the air compressor. Just like that, this repeated process many times will make the air compressor hotter and hotter.
To overcome the high temperature of the air compressor due to the high temperature in the air compressor room, we need to immediately install the hot air outlet pipe to facilitate the circulation between the air outside the environment and the exhaust gas to the compressor.

How to fix oil in compressed air?
When you see a lot of oil in the compressed air, the separation filter is not working effectively.
The oil separator filter can be damaged as follows:
-
Do not change the oil separator filter for a long time, causing the oil separator filter to be clogged and clogged
-
The oil separator filter is torn and dented due to the pressure of compressed air
-
Change the oil separator filter without changing the oil, change the oil filter. When the oil is still dirty, the residue will clog the separator filter
-
The oil return line from the separator filter to the compression chamber
-
The oil pipe inside the separator runs to the bottom of the oil separator.
How when it doesn't work?
When the air compressor is not running, you need to check to see what the cause is and then develop an effective repair plan.
With the cause of the solenoid valve or the suction valve being dirty due to lack of regular cleaning leading to blockage, you can remove and clean the valve clean, change the oil, and spring for the valve.
If the solenoid or suction valve is to a certain extent, it needs to be to make the air compressor operate more efficiently and last longer.
