Rotary screw air compressors are a popular choice for industrial and commercial compressed air systems. They are more energy-efficient and have a 100% duty cycle compared to the 60% of piston systems. This means the rotary screw system is available more often as it produces less heat requiring far less time to cool down.
Components of a Rotary Screw Air Compressor System
A typical rotary screw air compressor system consists of several components:
- Rotary Compressor
- Water Separator
- Air Tank (Wet Tank)
- Particulate Filter
- Air Dryer (Refrigerated or Desiccant)
- Coalescing Filter
- Air Tank (Dry Tank)
- Regulator
These components work together to deliver clean, dry air. Ideally, your installation would include both a wet air tank and a dry tank. Although not required, having both can save your business thousands if you have the room. Air tanks are not expensive and the dual tank set-up can be beneficial.
Servicing Your Compressor
For easy service, it is recommended to install a 3-valve bypass around the particulate, air dryer, and coalescing filter. This enables you to service the compressor without turning the compressor off.
Conclusion
Assembling a rotary screw air compressor system may seem daunting, but with the right components and setup, it can significantly improve the efficiency and reliability of your compressed air system.
FAQs
Q1: What are the benefits of a rotary screw air compressor system over a piston system?
A: Rotary screw air compressors are more energy-efficient and have a 100% duty cycle compared to the 60% of piston systems. This means they are available more often as they produce less heat and require less time to cool down.
Q2: What components are needed for a rotary screw air compressor system?
A: A typical system includes a rotary compressor, water separator, wet and dry air tanks, particulate filter, air dryer (refrigerated or desiccant), coalescing filter, and a regulator.
Q3: Why is it recommended to have both a wet and dry air tank in the system?
A: Having both a wet and dry air tank can save your business thousands if you have the room. Air tanks are not expensive and the dual tank set-up can be beneficial.
Q4: How can I service my compressor without turning it off?
A: By installing a 3-valve bypass around the particulate, air dryer, and coalescing filter, you can service the compressor without having to turn it off.
Q5: Are rotary screw air compressors suitable for all industrial and commercial applications?
A: Yes, rotary screw air compressors are a popular choice for various industrial and commercial applications due to their high performance, efficiency, and 100% duty cycle.
