Why use a rotary screw compressor?
A screw compressor can operate at high speeds while combining a large flow rate with small exterior dimensions. There are two primary
rotary screw compressor versions; oil-free and oil-injected. For each version, there are options of fixed speed or variable speed drive operation.
Rotary screw compressors operate with optimal energy efficiency.
Other benefits include:
- 100% Duty Cycle
- Continuous operation at temperatures up to 46 degrees
- Low noise output
- Low oil-carry-over in oil lubricated machines
- Zero loss of capacity over time
What is a screw compressor and how does it work?
Refrigerated air dryers from 750 liters/min up to 6500 liter/min ex-stock. Larger ex overseas. Dew point 4°C under pressure. Automatic drain pre and manual drain after filters.
Screw compressors have no valves or other mechanical forces to cause imbalances unlike piston compressors.
Airpower keeps universal spare parts for compressors. Pressure switches, non return valves and safety valves are universal to all compressors. Bottom entry filters/ regulators, electric motors and starters can be used for many makes of compressors.
