Rotary screw compressors are reliable and dependable. And, Atlas Copco makes the top of the line air compressors. Rotary screw compressors can be useful for a wide range of applications. Iacono Inc can help choose the right Atlas Copco rotary screw compressor for your business.

How do Rotary Screw Compressors Work?

These are fairly simple machines. Two rotors rotate in the opposite direction, which draws in air. This screw element is the most important element of the air compressor.

Because of the simplicity of the machine, they can operate at high speeds. Without any other valves or mechanical parts, they are able to operate powerfully, yet quietly.

There are two main categories of rotary screw compressors: oil free and oil injected. At Iacono of Long Island, we can help you choose the right one for your needs.

Do I Need Oil-Free or Oil-Injected Compressors?

As the names suggest, these two types of rotary screw compressors function either with or without oil. Your choice should depend on your end-product and application.

Oil Free Air Compressor

When selecting your Atlas Copco Rotary Screw Compressor, you need to assess your facility’s needs. If your product or application needs to be oil contaminant-free, then oil-free is the way to go. For example, a food production facility would not want to use an oil injected rotary screw compressor.

Oil Injected Air Compressor

Oil lubricated units are more economic. Therefore, if there is no immediate need for oil-free applications, then oil injected is right for you. Although there may be traces of oil in the compressed air, there are many air compressor accessories to help filter the air.

Other Considerations

Aside from your end-product, there are other considerations when choosing the right rotary screw compressor.

In cases of heavy daily use, the lifespan of an oil-free air compressor will be significantly shorter. Therefore, if you need to run your air compressor continuously, then oil-free is not the way to go.

Atlas Copco GA/GX Series Oil Injected Rotary Screw Compressor

The GA series offers better performance, lower noise, and a smaller environmental footprint. Atlas Copco GA series is ISO 9001, ISO 14001 and ISO 1217 compliant.

Compressed air models in the series GX, GA, GA+, and GA VSD+ are designed to operate in the harshest environments. The superior screw element and motor create a reduced lifespan cost. Specifically, the VSD+ will reduce energy costs by an average of 35%.

Atlas Copco SF and Z Series Oil-Free Rotary Screw Compressor

Both the SF and Z series will deliver quality, oil-free air. Since there is no oil, there is no need for additional products such as an air compressor filter. Oil-free compressors deliver clean air, which creates less waste in comparison to oil lubricated compressors.

The Atlas Copco SF air compressors are super efficient, while being compact. They can satisfy a wide range of applications, and will fit in smaller locations for maximum efficiency.

Z series oil-free compressors can satisfy a wide range of needs. These machines are commonly used for pharmaceuticals, electronics, textiles, and more.
