How To Choose The Right Air Compressor For Your Air Tools
Air compressors to differ from electric compressors in many ways. They generally have higher maximum pressure and much greater capacity than an electric compressor. This increases the level of service life provided by them. However, there are some advantages and disadvantages to using air compressors. These should be considered when purchasing one for your business or home use.
Compressors come in two forms; gas engine or electric motor compressors. Gas engine compressors are more commonly used in industrial situations, as they tend to run more powerfully and do not require much maintenance. Electric compressors can be more efficient in the long run if maintained properly, however they are much less powerful and so require a lot more energy. They also have a shorter service life than gas engines. This means that they will be much more expensive to operate over time.
An advantage of most gas compressors is that they have a low to medium duty cycle. This means that they will be able to maintain a constant flow of compressed air at all times, which saves on maintenance and cleaning time. The next advantage to consider is that these compressors are generally smaller than an electric compressor, which has significant advantages in terms of space. Most businesses will find that they can fit a gas compressor in their work area relatively easily.
The next consideration is the compression pressure and the maximum pressure that can be achieved. The PSI, or pounds per square inch, is the maximum pressure that the compressor can achieve in a given period of time. This number is measured in grains of air per minute, or GPM. Higher PSI compresses air with greater pressure, which leads to better power and speed. Lower PSI compressors tend to produce slower air streams and therefore result in lower power and less speed. Gas compressors also tend to have higher cylinder pressure, which results in more consistent pressure and better performance over time.
The next thing to consider is the working pressure and the maximum pressure that can be achieved through each compression cycle. This is measured in British pounds per square inch. GPM is often times confused with PSI, as both measurements are typically used in the same circumstance. While GPM refers to the maximum pressure that is reached through a single cycle of compression, it does not necessarily indicate the highest or lowest pressure that can be achieved during any given cycle. Working pressure is typically measured in pounds per square inch. When considering the PSI vs. GPM of a compressor, it is important to keep in mind that both measurements measure compression pressures and are used solely for comparison purposes.
Another factor to consider is the power source for the compressor. Many industrial compressors are powered by an electric motor, and a gas engine powers many home-grade compressors. While there are advantages and disadvantages to each type, the most common factor is the reliability of the power source. Gas engines tend to have a much longer life span, but are far more reliable than electric motors.
The final factor to consider is the size of the compressor. The largest and most expensive models will have the best performance, but they also cost the most money. A good rule of thumb when determining the size of the compressor that would best fit your needs is to assume that the compressor would need to run continuously at the rated speed of your tools for at least eight CFM, or about five hours. In order to determine this, you would need to measure the life of the compressor's power source and divide that number in half. For example, a two-stage compressor that outputs at five hours of continuous power output would have a life expectancy of approximately three hundred hours.
Compressors can be broken down into three general categories. The most basic, slow-speed, continuous use compressor is probably the best option for most users. The other two types are fast-speed continuous use compressors and top-speed continuous use compressors. Each of these types has its own advantages, and it is a personal choice that will vary depending on the use of the tool. The final factor to consider is the tank size, which is generally determined by the motor's capacity, the capacity of the compressor itself, and the intended application.
