What are the advantages of using a Rotary Screw Compressor?

Air compressors come in many types, rotary screw, piston, scroll, reciprocating, some are oil-free and other air compressors require oil lubrication. Like many businesses, an efficient air compressor is at the heart of their operations. So, which type of compressor should you choose? What makes a compressor, like a rotary screw, unique? Here are some clear cut benefits of equipping your business with a rotary screw compressor

A lot of industries rely on air compressors for material handling and use for machine tools. Our Rotary screw compressors are highly popular because they pose these 8 advantages:


1. Safe and Convenient

Rotary screw air compressors are incredibly convenient, given that they deliver air continuously for the required purposes. They are also safe, and cases of accidents with the machines are almost unheard of.

2. Functions at extreme weather conditions

Rotary air compressors can work at high temperatures or in low conditions to your convenience. The machines can also work in areas where other forms of energy are prohibited due to safety or temperatures levels. Our rotary screw compressors run continuously, and this continuous duty function means that the rotary screw compressor can run all day, in all conditions without wearing out crucial components of the machine. 

3. They are designed to run tools that generate more power that typical equipment 

And since their air flow rates are extremely high, rotary air compressors can power such equipment effectively.

4. They are easier to maintain 

Many of the modern air compressors in the market have fewer parts that require maintenance. In fact, some rotary screw machines have up to 70% less of parts, which in turn lowers maintenance costs dramatically. Although easier to maintain, they do still need maintenance and as long as you keep with a rotary screw maintenance schedule, you will likely be rewarded with many years of optimal productivity from your machine.

5. They run quietly despite their massive air flow

Rotary screw air compressors are generally quiet performers, with many of them having noise dampening technologies. That and the fact that they are not huge in size makes them convenient to be stored anywhere and till provide a safe working environment. Many rotary screw compressors are barely louder than a dishwasher, so you can still have conversations in your compressor room, and not feel like you have to yell over the noise.

6. They are good energy conservers 

Rotary screw machines are generally energy efficient, and they generate less heat than normal air compressors.

7. They consume less oil than other oil flooded air compressors.

In addition, they have minimum oil carryovers. Our rotary screw compressors do an exceptional job of sealing in the lubricating oil, which means that your workshop or compressor room will be drier, cleaner, and suitable to situations that demand low air moisture. 

8. They are designed to last 

Rotary screw air compressors are designed to serve you for many years, all along while having little or no capacity reduction.

That cold, rainy, and in some places icey New Zealand winter is upon us, and with the following air compressor tips, your air system will be prepared with the preferred temperatures, despite the weather outside. Regardless of whether or not it actually snows or freezes up where you live, most winterisation service recommendations are also basic, solid maintenance procedures that will help extend the life and operational efficiencies of air compressors regardless of whether you live in Queenstown or Northland.

If you're wondering what an air compressor actually is, you've come to the right place. Simply, air compressors convert power in to air that is pressurised which is then used to power air tools such as spray guns. Air compressors are used in a wide range of applications, so naturally if you want one that will be designed for spray painting your vehicle, you want a compressor specifically made for spray guns! This way your compressor will be able to provide the right amount of power to perform the job.
