Things to Consider Before Buying a Rotary Screw Air Compressor

Rotary screw air compressors are a highly efficient gas compressing tool. They function by trapping air between two meshed rotors. They reduce the air volume that has been trapped by moving it down through the rotors. The decline in volume paves the way for compressed air that can be used to inflate tires, provide thrust-to-air tools, and be used in several other applications.

Rotary screw air compressors, in our opinion, are best suited for industrial applications that can operate seamlessly only through an uninterrupted supply of compressed air. But kindly note that this is not a one-size-fits-all type of product. To make an informed buying decision, you must possess a certain level of product awareness. Here’s a quick list of some of the most critical consideration factors that you must keep in mind when you are in the market to shop for the best rotary screw air compressor.

#1 Stationary vs. Portable

Portable compressors are either powered by a diesel engine or an electric motor. They typically operate on wheels, but it is not mandatory, as portable compressors can also work standalone. We recommend using this type of compressor in areas where electrical power is not readily available. But kindly stay cautious when using a diesel engine-driven air compressor because most of them do not come with aftercoolers. Therefore, the machine might get overloaded with hot wet air, negatively impacting the overall performance. We recommend a stationary air compressor unless you want to use it in an area where you will not get a quick electrical power supply. 

#2 Type of Drive Matters

There are three options in rotary screw air compressor drive types- belt, direct, and gear driven. Gears and belts provide versatility in manufacturing but incur massive transmission losses compared to its alternative. You may experience a reduced efficiency when using a belt or gear-driven air compressor. Many modern-day compressors come with a variable frequency drive. We always recommend using such a product as they help manage motor power consumption better under different load conditions.

#3 Consider Where You Will Use It

​​Compressors used in outdoor areas encounter different ambient air temperatures and humidity. They also deal with the highest level of dust. Therefore, we recommend buying a heavy-duty industry-grade air compressor for outdoor use. The excellent news is outdoor installation ensures a more accessible option for cooling. On the other hand, you can consider a sophisticated version of a rotary screw compressor if you want to operate it indoors. You may need additional noise reduction resources if you are planning on using your air compressor inside.

These are a few factors you must consider before buying a rotary screw compressor. We recommend consulting with an expert before finalizing your buying decision.
