How To Choose The Right Rotary Screw Air Compressor

Rotary screw air compressors are one of the most popular types of industrial air compressors. They offer a lot of benefits that make them ideal for any application that requires high volume, medium pressure air. When you’re looking for the right air compressor, here are 5 things you should consider: 


Rotary screw air compressors are powerful machines that are capable of operating a wide range of heavy equipment and pneumatic tools. They are also great energy savers. Compressed air power is measured by CFM (Cubic Feet per Minute) and psi (Pounds per Square Inch). These metrics help businesses identify the best air compressor for their needs. Unlike reciprocating air compressors, which are cycled on and off, rotary screw air compressors are designed to run 100% of the time. This makes them a good choice for factories and other industrial locations where it’s important to operate air tools at the peak of their efficiency all day long. They also offer higher psi and greater air flow than other types of compressors. 


If you’ve ever been to a factory or pressing plant, you may have noticed that they use rotary screw air compressors. These machines are compact, energy efficient, and durable. Despite their compact size, they are more efficient at higher outputs and are easier to operate than reciprocating air compressors. They are also less expensive to operate, reducing your overall operating costs. 


Typically, rotary screw compressors run at lower temperatures and generate less noise than piston air compressors. This is because the rotors do not come in contact with the cylinder walls and therefore do not create friction, which raises temperatures. Moreover, they have minimal vibration due to their rotating motion. This makes them ideal for sensitive environments where vibrations can interfere with equipment. 


The oil used in rotary screw air compressors plays a significant role in the performance of these machines. It is responsible for lubricating, sealing, and cooling moving parts, as well as providing corrosion protection to the rotors. The oil is pumped into the compressor and then mixed with air during compression. It is then separated back out again before compressed air leaves the unit. These units also have a much lower oil carry-over rate than piston-based compressors, which means that you will not need to change the filter elements as often. If you need clean air in your industrial application, an oil-free rotary screw compressor is a good option. Meanwhile, water-injected rotary screw compressors are a great choice for applications that require 100% oil free compressed air. 


Like all compressors, rotary screw models need periodic maintenance to stay functioning properly. This routine inspection helps to keep the machine healthy and working, and also extends its life. Depending on the manufacturer and model, rotary screw air compressors require a specific service schedule that can range from once every 3,000 hours to 8,000 hours. These schedules will vary based on factors like the oil type used and the operating conditions.
