How to Select the Right Scroll Compressor


Scroll Compressors are fantastic machines. They are efficient, quiet, oil-free and easy to maintain. Because of these attributes, they make an excellent choice for a variety of applications. But before you run out and buy one, consider a few factors that will help you make the right choice: air quality, air pressure and electrical service.

Air Quality

When it comes to picking one for your facility, first consider the needs of your application. Scroll compressors are already a great choice for sensitive applications, because they don’t require lubrication in the compression chamber. However, different applications have unique needs when it comes to moisture and particulates. If air quality is a consideration, look for options that come as a complete package with an air dryer and in-line filters included.

Air Pressure

Like all compressors, scroll compressors are rated in pressure (pounds per square inch, or PSI), power (HP) and flow (cubic feet per meter, or CFM). Though it may seem elementary, knowing what pressure, power and flow your end use requires is of vital importance. If you’re not sure, you can schedule an audit with a professional. They can walk you through determining your individual compressor needs.

Electrical Service

This may not seem like a big deal, but it can be, and better to address it before you accidentally ruin a machine. Unless you are working in a large industrial facility, you most likely have one phase power. If you’re using a compressor at home or in a small facility, you probably are using single-phase power.

However, another way to determine is to see if your facility has typical outlets or wall-mounted boxes, as three-phase power doesn’t come out of traditional outlets. Usually, three-phase power can support larger machines. It is always a good idea to consult an electrical expert before installing a machine.
