How to Assemble a Complete Rotary Screw Air Compressor System
Rotary screw air compressors are a popular choice for industrial and commercial compressed air systems. Though business owners typically start with a more familiar piston air compressor, which includes the piston compressor mounted on a 120-gallon air tank, as your demand for compressed air increases we recommend changing to a rotary screw air compressor system. Rotary screw compressors are not only more energy efficient but also 100% duty cycle, versus just 60% for piston systems, meaning the rotary screw system is available more often as it produces less heat requiring far less time to cool down.
Since rotary screw air compressors are less familiar to most people, let’s take a look at a typical system. Rotary screw compressors are available in sizes from about 5 to 500 hp and come in a variety of configurations: base-mounted; tank-mounted; and tank-mounted with the compressor, tank, and dryer. To deliver clean, dry air, you’ll also need a variety of components:
- Rotary Compressor
- Water Separator
- Air Tank (Wet Tank)
- Particulate Filter
- Air Dryer (Refrigerated or Desiccant)
- Coalescing Filter
- Air Tank (Dry Tank)
- Regulator
Ideally, your installation would include both a wet air tank and a dry tank. It's not required you have both but it’s a good idea if you have the room. Air tanks are not expensive and the dual tank set-up can save your business thousands. For easy service, we also recommend installing a 3-valve bypass around the particulate, air dryer, and coalescing filter. This enables you to service the compressor without turning the compressor off.
