Compressor ratings are based on the current compressor technology. Each compressor has been designed to perform a specific job. The manufacturer has to make sure that their machine can be used for that job and they only add features that can be of use in performing that job. This is why there are many different compressor ratings. If you need information on what each machine can do, you will have to go through a compressor ratings system. This is done so that the average person knows how each machine is rated.
In a compressor ratings system you will find many things. You will find the amp rating of the machine as well as its pressure rating. In addition to this you will find information on the speed of the compressor. The compressor rating is in relation to the engine of the machine. Most machines with higher rated are more powerful than the ones with lower rated. Also you will find the maximum pressure that the machine can handle. All of these things are important to know before purchasing any compressor.
Some things you will learn about the compressor ratings are how big the machine is. The bigger the machine the better it will be able to handle the workload it is designed for. Of course, if the machine is too big it might not be able to handle the workload it is designed for, but if it is too small then it may blow up or break down. Knowing these things before you purchase your compressor will help you make the right decision.
