Air compressors are a very useful and handy device used commonly in construction sites and automotive shops. They are also very useful at home depending on the kind of work you do. Air compressors are designed in order to covert pressured air or gas into to kinetic energy; this energy is then used in powering household tools.
However, when deciding whether you buy a gas or electric compressor, you must know the difference between the two. The kind of air compressor you buy also depends on your requirements.
Keep on reading this article to find out the difference between electric air compressors and gas air compressors
Electric Air Compressors
Electric air compressors are more convenient than gas compressors especially if there is an electrical power supply near you. These compressors are also very affordable and can be used with various applications. These compressors come in permanent design as well as portable design depending on what you are looking for.
You also get a start and stop switch that you can use. Once the pressure decreases in the tank, the compressor shuts itself down automatically. If the pressure gets too high, then the unit will shut down as well. This generic switch comes in handy since it stops the motor if no tools are being used on it. Electric compressors, however, cannot be used with extension cords.
These compressors are not ideal for heavy duty work as compared to gas compressors and cannot withstand high construction and industrial jobs. But these electrical compressors work perfectly for indoor work and small household tools.
As long as you have access to electricity, these compressors can work anywhere you want. They run smoothly without making any noise, and they also have no toxic byproduct. This makes them great for use indoors. With these compressors, you can say goodbye to refueling.
Since they do not release harmful fumes or make noise, they do not distract your workers and employees. They are also lighter and easier to move since they do not have any fuel storage as compared to gas compressors. This allows them to be put in many different places without worrying about any flammable fuels nearby.
However, you must be aware that this applies for small electric compressors; large electric compressors are fixed and permanent in one place so they cannot be carried from one place to another. Generally, electric compressors are easier to use since they have a simpler process and require less maintenance in regard to the fuel source. They can also run easily at low temperature and can be placed anywhere near a power source.
Gas Air Compressors
Gas air compressors provide the same amount of pressure as electric air compressors. Both of these are not much different when it comes down to their performance. But the main difference between the two is their source of power.
Electric air compressor depends on electricity whereas gas compressors depend on gas to perform. Another main difference between the two is their stop and start system. Like electric compressors that can get turned on and off on their own once the pressure is filled, gas compressors cannot.
They do however have a pilot valve which opens and closes itself to verify the pressure present in the tank. This mechanism is great for tools which require a predetermined flow of air such as sanding tools, sprayers, and grinders. You must also keep in mind that these gas air compressors are not meant to be used inside. They are very noisy and release toxic fumes; inhaling these fumes can risk your health.
Also since gas is a flammable substance, you must be very careful while using it. These compressors are also very heavy than electric compressors.
Size And Power
One important thing to keep in mind when shopping for an air compressor is that gas air compressors are similar to a wheelbarrow. They come with twin tanks, an engine along with a compressor and are perfect for heavy-duty work in an open environment.
With these gas compressors you do not have to worry about powering the compressor; similarly, fill up the fuel according to your needs and use it easily. But you must keep in mind that the heavier the unit, the louder it is.
The bottom line is that if you have access to an electric socket nearby than opting for an electric air compressor; these compressors are quieter, more efficient in terms of power and since you do not have to refill the tank every time, they are also fuel-efficient.
Some Specifications To Focus On
When buying air compressors do take some time out to look at the power each compressor has in terms of PSI and CFM. PSI stands for pounds per square inch whereas CFM means cubic feet per minute. Make sure that you match the power of your tools with the power of the compressor you buy; this will let you know how much power you need.
If you plan on powering various tools at the same time, then try to get an air compressor that has enough pressure to power them all. The more the air pressure has the more power it can supply. This is something you must focus on when buying a compressor because the more pressure in the compressor, the easier your work will be.
Reciprocating Screws And Rotary
Most air compressors present in the market make use of rotary screws and reciprocating. While reciprocating can be used commonly for indoor uses, they are pretty useful. On the other hand, rotary screw compressors are used mainly for construction sites and industrial appliances; these screws help in providing the user with consistent air supply, therefore, are better for heavy-duty work where air supply is needed constantly.
An air compressor has many advantages. They are easy to maintain, are a versatile tool and help in speeding your work at home. They also help in heavy duty jobs and construction. However, it is important that whatever kind of air compressor you buy, must meet your needs. For this to happen, you must understand the needs and requirements of your business.
Once you are aware of what you are looking for, then you must focus on the following features of an air compressor:
- It’s size
- The airflow of the air compressor and is it enough for your tools
- Your work environment; are you indoor or outdoor?
- The size of the compression tank
- The tools that need to be powered
- The horsepower that your work requires
- Your control systems
- The right protection needed
- The price
- A reliable company
Also, focus on some other features such as oil-monitoring devices that will help in reducing problems caused by low levels of oil; stainless steel valves that will help in getting rid of corrosion. Also, check for one-piece connecting rods that will help in reducing any internal adjustments require by you. When buying an air compressor make sure that the fewer the parts are, the lower the maintenance cost will be.
