3 Things to Consider When Buying a New Air Compressor

Air compressors come in many shapes, sizes, and styles. When you're looking for a compressor for a high-demand environment, there are several things that you should consider. While it may stand to reason that you need to consider how much pressure it can generate, you may not be aware that you should also think about the duty cycle, the actual air demand, and the power needed for the system.

Here's a look at each factor to help you decide what kind of compressor is right for your needs.

What Kind of Power Do You Need?

One of the things that's easy to overlook until it's too late is the power demand for the compressor. Before you start looking for a unit, have your building evaluated by an electrician to determine what kind of power phase your building is wired for. You may have three-phase wiring available, or it may only be single-phase. You'll have to know which it is to choose the right compressor for it.

What Kind of Duty Cycle Do You Need?

The duty cycle of a compressor refers to the amount of time it will run before the compressor has to shut down to reset. In most cases, it's expressed in seconds per minute. You'll need to think about how much time the compressor will spend running before you choose a model.

For example, with traditional compressors, you may have a 45-second duty cycle, which means that it will run for 45 seconds out of every minute and shut down for 15 seconds before starting again. In a really demanding environment, you might need a compressor with a constant duty cycle. That means it won't shut down at all. Rotary screw compressors are constant duty cycle systems because they use a pair of rotors to compress the air.

How Much Air Will You Need?

Most machines and power tools are clearly rated for the amount of air and the pressure level that they require to operate properly. If you're opting for a traditional compressor, you'll need to evaluate the pressure produced and capacity of the storage tank to be sure that you'll get the air that you need for your tools.

If you buy a rotary screw compressor for sale, there's no storage tank capacity to be concerned with since it runs continuously, but you'll still need to consider the air production and the pressure level. Make sure whatever compressor you choose will sustain the demand of your highest-rated tools and equipment.
