A Comprehensive Guide to Rotary Screw Air Compressor Ratings and Metrics- Insights for Beginners

Being introduced to the world of air compressors can be quite confusing and overwhelming for anyone. Without understanding the fundamentals, one may fail to understand what they are looking for and identify the right one among the myriad air compressors. So, before you look for a rotary air compressor, you must gain a proper understanding of the basics.

In this regard, you can start learning the metrics and ratings associated with the features and performance of an air compressor. With deep insight into these factors, you can evaluate the air compressor availability in the market and identify the right one for your industrial needs. If you are new to rotary air compressors, dive into the following factors and master the metrics and ratings of air compressors.

To comprehend the features of a rotary air compressor, you need to be familiar with the acronyms PSI (pressure), CFM (flow), Duty Cycle, and HP (power). These are the most significant principles of air compressors that enable you to determine the size of compressors suitable for your specific application. These factors help to select the proper air compressor that can cater to all your industrial needs.

An Overview of PSI, CFM, HP and Duty Cycle: Prime Ratings of Air Compressors

# PSI (Pounds per Square Inch)

Pounds per Square Inch (PSI) represents the level of air pressure or force generated by the air compressor per square inch. In most cases, air tools may necessitate 40 PSI or 90 PSI to achieve optimal performance for various tasks. However, tools used in industrial environments, especially those designed for cutting steel or other metals, invariably demand a compressor with the highest available PSI rating.

# CFM (Cubic Feet per Minute)

CFM is an acronym for Cubic Feet per Minute. It is a common way to measure airflow, specifically, the volume that is used to indicate the airflow from an air compressor over time (volume/time. The airflow is measured at atmospheric conditions in which the compressor is operating. Each compressor comes with specifications for cubic feet of compressed air per minute (CFM) while flowing from the discharge port. So, based on the requirement of compressed air, you can choose the level of CFM ratings. For industrial purposes where the need for compressed air is higher, you need to choose a rotary screw air compressor with high CFM ratings. 

# HP (Horse Power)

HP, or horsepower, signifies the work capacity of a motor. While horsepower is a significant factor, it's not as crucial as pressure and flow when evaluating whether a compressor is suitable for your needs. This is because modern and highly efficient compressors can achieve greater performance with lower HP. Achieving more with less HP not only conserves energy but also yields substantial benefits over the compressor's lifespan, resulting in cost savings and improved efficiency.

# Duty Cycle

The duty cycle pertains to the duration between the on and off phases of a compressor. When a compressor is in the 'off' state, it does not necessarily mean the machine shuts down completely, but rather, it remains inactive without pressurizing for extended periods. All compressors have a designated duty cycle rating. Rotary screw air compressors are ideally suited for continuous and medium-duty applications. If employed for shorter periods, it is advisable to run a rotary screw compressor long enough to reach its full operating temperature to prevent condensation from accumulating in the oil system.

There are other crucial factors as well, such as tank size, noise levels, and portability, that have significance in the selection of the perfect air compressors for specific applications. By understanding these metrics and ratings, it will be much easier to have a better idea of different air compressors and their capacity and you will be able to make smart and informed decisions to find the right one to match the requirements of your pneumatic tools and ensure efficiency.
