Buying an air compressor requires careful thought and consideration. An ideal compressor requires focusing on many performance factors. An Air Compressor Buying Guide is the starting point before you make this decision. This article discusses the factors you need to consider before making your last choice.
Check the needed Standard Cubic Feet per Meter output – S.C.F.M.
This is one of the most important factors. It is the Standard Cubic Feet per Meter output of a compressor. This is also the volumetric output of a compressor. It is normally higher than or almost equal to your consumption. A high output is achieved with a bigger compressor.
Check the pressure capacity of your compressor
In order for the targeted flow rate to be achieved, pressure is needed. This pressure is normally given in pound per square inch. It changes according to the compressor size, brand and design. If it is needed for heavier applications, the pressure should be higher. With an increased pressure, even the flow rate or output is also increased. Most importantly, the flow rate has to match your targeted consumption.
Why do you need that compressor?
The usage of your compressor dictates the ratings you should be looking for. If you only need it for some domestic purposes, something smaller would be enough. However, if you have a number of air tools and other equipment to use the same source, then you need a bigger compressor. The rating of each tool is easy to check from the indicated values. Add up the capacities of all the tools and include a 30% allowance.
From where are you going to tap electric power?
Your source of power is critical because it even dictates the size of compressor you can use. If there is a constant supply of electricity, then a single stage reciprocating compressor can be a good choice. But if you are in an area that is persistently hit with power cuts, shut downs and load shedding, the reservoir type is your right choice. You can run it when there is power, and use it whenever there is need. It will keep the needed pressure for long hours depending on your usage.
How much space do you have for your compressor?
Before your compressor is installed, you need to arrange enough space for it. This means that if you have enough space, a bigger compressor would be ideal. But if there is no space to accommodate a bigger compressor, buy a portable one. However, space considerations need to come only after you are satisfied with the performance. In some cases, you may even need to create space.
What are some common horse power ratings?
The horse power rating of a compressor needs to be considered just like the other factors. A variety of compressors may have their ratings ranging from 1.6 to 6 horsepower. However, this factor is normally governed by the pressure and S.C.F.M. of the compressor. The power rating should not be a standalone factor. It should meet the requirements for your usage.
Summary of requirements
In conclusion, your compressor should match the usage you are buying it for. Therefore, the best Air Compressor Buying Guide you need should answer your performance questions. Most manufacturers provide the needed details. With the best guidance, you will stand a chance of buying the best equipment to work for many years to come.
