5 Questions You Must Ask Yourself Before Finalising Rotary Screw Air Compressor

Compressed air is used in various industries. For different applications, different types of air compressors are used. Industrial air compressor manufacturers design and build a variety of tools to offer you the one you desire. 

Since there are a lot of choices, it becomes easy for the buyers to select the one they need. But, to fit your needs, you first need to analyze your requirements. Do you know what exactly your industry wants? If not, ask yourself the below questions and you might have it clear. 

What Are Your Expectations From The Compressor? 

Rotary screws can work flawlessly for long hours. They can work 24 hours a day which means they offer you 100% usage irrespective of time. The rotary screw compressors can provide your large amount of demand. Even in smaller horsepower, the compressors are way more durable than other compressors. However, if you might need larger horsepower, such as 15 or more, then you might need to consider some other compressor. 

Do You Want To Consider Lifetime Investment? 

You can either invest less for one time and keep paying in terms of rebuild requirements over short intervals or pay more at once and set free for the time ahead. A rotary screw compressor is expensive at first and wants enough maintenance too, but the lifetime is much greater than other compressors such as piston type ones. While piston-type compressors might start wanting to rebuild after 10,000 hours, a rotary screw can work flawlessly up to 60,000-80,000 hours before needing a rebuild. 

Is Noise An Issue For You? 

Many people don’t consider noise as a big problem at the workstation before their staff stays away from the place. But, if there is little distance and the team might get disturbed by noise, a rotary screw compressor is the one you need. 

Rotary screw compressors have a low sound enclosure which keeps its operating noise between 65-75 dBA which is quite less than a piston-type compressor which causes noise between 80-85 dBA. Other compressors also work at a high dBA in comparison to a rotary screw compressor. Moreover, it is also environment-friendly as higher sound can cause noise pollution in the environment leading to mass disturbance.

How Much You Can Feed Your Compressor? 

The feeding needs can also affect your choice. Rotary screw compressors can take a maximum of 3PPM oil carryover. Considering other compressors, some of them like a piston-type compressor can demand high fuel as it ages. The feed oil carryover can go up to 10 PPM which is quite high. 

Lesser the oil carryover, the higher will be the life of filter elements because they will be used less. So, it will not only cut down on operating costs but maintenance costs as well. 

What Is Your Compressed Air Requirement Schedule?

How much or how often do you need compressed air? Do you need it continuously throughout the day? Is your compressed air requirement fixed according to time intervals or it varies every day? 

A rotary screw compressor can work for hours without needing any rest. They can work day in and out offering a 100% duty cycle. You can have compressed air any time 24/7. So, if you have constant high demands, a rotary screw compressor is a great choice. 

If your requirements vary throughout the day, then also you don’t need to think much. A rotary screw compressor can be slowed down or speeded up according to requirements. You can use it as per your convenience. So, if this is the only point for considering something else, you can go for it without thinking much. 

Not only are these compressors efficient and long-lasting, but the noise level is also a great plus point. Another thing that makes it worth is the price. The prices have gone significantly down in recent years and that makes it possible for you to get one for your industry as well. There durable body and low carryover makes them a cost effective and worthwhile investment for every manufacturer.
