Things To Consider Before Buying Best 12v Air Compressor…
It is very difficult for people to make up their minds upon buying the perfect kind of air compressor they are looking for, as the market is flooded with thousands of air compressors, not only online but also in nearby shops and brand outlets. You may find anything that might be interesting in any particular air compressor while a different thing that might attract you in a different air compressor. Therefore, lookout for some of the important key specifications that are mentioned below before making up your mind to get an air compressor for yourself.
1. Air Pressure
Air pressure or PSI is an important key point to look at while you are going to buy an air compressor. PSI is known as pressure expressed in pounds of force per square inch of area. You must know for what work you are buying an air compressor if you need a high-pressure air compressor and you opt for the one which is low powered then it will be more of a waste for you. The air compressors you come across are of 120 psi or of higher range and this range is more than enough to inflate tires of bikes and cars even.
2. Power Usage
An air compressor that draws high power can inflate things easily and quickly, but if you have connected it to your car battery it would surely drain it all. So it is recommended that you keep in mind the place of usage of the air compressor. If you need to use it for household purposes, then you can go for the one that needs high power because it is fast and efficient. But if you want an air compressor for your car to inflate your tires when they get low on air, then you surely need to own the one that requires less power. Although it may take time but would surely not drain up your car’s battery.
3. Length of the Cord
Once you are done connecting up your air compressor with the 12 volts power pin of your car, you still need to reach till the tires to inflate them. Thus, you need a decent amount of chord length with the air compressor. So, you can inflate up your tires and you need not carry any extra extension wire to reach the tires. It is recommended to go for the air compressor that has a chord length of at least 10 feet or above.
4. Auto Shut Off
Auto shut off is a key feature that you need if you are new to using an air compressor. This feature automatically turns off the device when there is enough air in the object that you are trying to inflate. This helps you from estimating and guessing whether the air is sufficiently filled. You need not have a regular eye while you’re inflating any object or even your car tire, as the device itself judges the amount of air needed and the moment it reaches that limit, it turns off automatically. So you should be very careful with this specification that whether the one you are going to buy holds this feature or not.
A display with an air compressor is a very handy feature. It makes it very useful for the user to operate the device, as you can monitor the current tire pressure and turn the device off when the required limit is reached on the display screen. Some of the devices have a feature to set the air pressure limit so that it gets turned off automatically.
Extra goodies with anything you buy are always a pleasure for the user, also these accessories make the product a more handy and useful option for the user. In accessories, you can find different nozzle heads that maybe for the car tires or for a sports ball. Few companies also offer a carrying bag with the air compressor for safely transporting the device. You could also find an extension wire for longer reach, some extra fuses or maybe an alligator clip to drive out power from a battery directly.
Types of Air Compressors:
For different types of households, there are various types of air compressors you can get online or can easily get from any store in your city. Two types of air compressors can be classified into the basis of their uses, that is, Residential uses or Commercial uses.
The one that is made for household usage is of lower power ratings and it generally works on DC power supply. Whereas the air compressors that are built for commercial use are of high power ratings and work on AC source or are fuel-powered.
The most common type of air compressors that people come around is the one that comes along with a sealed container to pressurize the gas. While there are various portable 12 volts air compressors available in the market these days. The basic purpose it serves is to inflate low-pressure items, such as balls, car tires, air mattresses and a lot more. You can see an enormous number of product claiming to be the best 12v air compressor on the internet.
Based on the internal mechanism, an air compressor can be classified into positive displacement or dynamic displacement air compressor. However, the common type you can see are:
Positive Displacement Compressors
This air compressor generates power via air displacement. The working of the air compressor is based on a very simple mechanism where the air is made to get inside a vessel or cavity which increases the air pressure and the potential energy of the vessel.
Rotary Screw Compressor
These are basically used in large scale industries. They are a common example of positive displacement compressors and are very easy to take care of as they come equipped with an internal cooling system, which makes this type of compressor to be taken least care of, that is, they need very minimal maintenance.
Reciprocating Air Compressor
Rotary screw air compressors comprise two internal motors, that run in opposite directions to generate energy by compressing the air in the vessel. The rotors that move in the opposite direction builds up pressure on the air that gets trapped within the housing.
Centrifugal air compressors use a diffuser to slow and cool the incoming air in order to build up potential energy. In the multi-phase compression process, a high amount of energy is produced in a relatively small machine through the centrifugal compressors.
Dynamic Displacement Compressors
Dynamic air compressors generate energy by bringing in the air with continuously rotating the blades and then storing the air to create pressure. Then the restricted air’s kinetic energy is stored as static energy inside the compressor. The DC 12 volts air compressor that we will review, lie under the same category of dynamic displacement compressors.
Benefits of Using a 12-volt Air Compressor
A 12-volt air compressor is mostly used for inflating tires of cars and bikes. But it can also be used with devices that need compressed air to work. The lightweight model makes it really easy for the user to carry it anywhere around. They cannot be used for big machinery as they need some high-powered air compressor for the work to be done.
Frequently Asked Questions About 12V Air Compressor
How long can you run an air compressor?
A. It depends upon the duty cycle of the air compressor. This rating is typically given as a percentage of the amount of time that an air compressor can be run in a full cycle, typically one hour, that includes the compressor’s run time and rest time. Mostly it is recommended to run it for 10 minutes max, then let it rest and you can start again later.
What happens if I run the compressor continuously for too long?
A. Running the air compressor for too long would start heating up the device. The heating could blow up the motor of the air compressor. The cigarette lighter plug of the air compressor may also meltdown and damage the socket of your car.
Can air compressors get wet?
A. Water can easily damage the inner parts of the compressor, as things corrode as they get in contact with water. The device might also malfunction, or the motor winding would blow up. So, it is recommended that you keep a distance with water and the compressor.
What causes an air compressor to overheat?
A. One of the main problems that can cause an air compressor to overheat is a high compression ratio, which is typically caused by low suction pressure.
Can we run the vehicle while the compressor is in use?
A. It is surely not recommended to run the vehicle while the compressor is still in use. You should turn on the vehicle so that the compressor can get power. But you should never run the vehicle.
How long should be the power cord?
A. The power cord should be long enough, so as to reach the rear tires of the vehicle. It is recommended to have at least 10 feet long power cord to ensure that you need not apply any extension cord to increase the length.
Do air compressor drain battery?
A. If a stand-alone battery is being used to operate the air compressor then, it will drain the battery in approximately 20 minutes. If you are using the battery of your car then you must ensure that the ignition of the vehicle is on, otherwise, the compressor will drain the battery very quickly.
How often we should clean the air filter?
A. If you clean the air filter on a weekly basis, there would be no debris deposit on the filter. Thus, will give you longer using duration.
What is the difference between start-stop and constant run compressor?
A. The compressor provides you with the control on the running of the compressor by adding a start-stop button. While the constant running compressor, once powered on can not be controlled by the user, they run continuously until the power is turned off.
What voltage the compressor should be operated?
A. Most portable compressors are made to run on a 12 volt DC supply, that is easily provided by the car battery. However, there are many products that are compatible with both DC 12 volts supply as well as AC 120 volts power supply.
Can a compressor run on a generator?
A. The compressor is designed to run on a specific amount of power supply, adding extra power or using it with a high power supply would surely damage the coiling of the motor present in it. So, using the compressor on the specified power supply is best recommended
It is recommended for people to have a 12 volts air compressor in your car, as it could result in a blessing in disguise. Travellers must carry an air compressor to inflate your low-pressure tire, as people rarely get any pump station while travelling. There are many 12 volts air compressors that you can choose from either online or just by visiting any retail shop nearby. However, the important thing is that before buying best 12v air compressor you must be aware of the specifications and features you need to look into the product which you are wishing to buy.
