Air compressors offer users many benefits because they can be used for a variety of tasks once they are attached to air tools. The units make tasks such as inflating a car tire seem easy. Air compressors can be used for domestic or commercial purposes. If you are thinking of buying a compressor unit, there are a number of considerations to keep in mind. Here is an aircompressor buyers guide.
Understanding air compressor measurements
Keeping in mind that air compressors are available in many types and sizes, you need to be clear on the type of task you want the unit to perform. The task you intend to perform on a regular basis will determine the capacity of the unit you choose. The power of the compressor is measured in Pounds per square inch (PSI). A unit that can compress more air has a higher PSI and thus delivers more power to your tools.
You also need to be conversant with the unit’s Cubic Feet per Minute (CFM). This measurement refers to the amount of air a unit can pump in a minute at a certain pressure. If you are looking for a unit for heavy duty or commercial tasks, you need one that has a higher CFM. Another important measure you need to consider is the compressor’s Horse Power (HP). The HP of an air compressor is determined by the amount of power that its motor produces. If you need a unit that has the capacity to deliver more power, you need to go for one with a higher HP.
If on the other hand you plan to use the unit for long periods of time, then you need to consider the size of the tank. If a unit has a large tank, it requires a more powerful motor in order to fill it up and compress the air. Such a unit therefore needs to have a more powerful PSI and will serve you for longer periods before you have to refill it again.
Type of air compressor
After you have made a decision on the capacity of the air compressor you need, you can then decide the specific type of compressor that will meet your needs. There are three main types of compressor units to choose from. They include the Wheelbarrow style, a twin-stack style and the pancake style. If you need a highly portable air compressor unit, your best option is a twin-stack style unit because you can use it on a variety of small maintenance tasks around your home. Should you need a lightweight unit for use in small spaces, the pancake type is a good choice. This type of unit can be used for both indoor and outdoor functions because it is mostly electric powered. In the event that you need a powerful unit that you can carry around a construction site, the wheelbarrow-type air compressor is your best bet. With most of these wheelbarrow-type compressors powered by gasoline, it is best to use it outdoors due to the noise it generates.
Once you have chosen your preferred type, you will need to look at the extra features such as whether it has two air outlets, an electric start system and whether it has an idle control. Based on the above, you should be in a good position to purchase the right air compressor for your needs.
