Why use a rotary screw compressor?
Unlike piston air compressors, screw compressors have no valves or other oscillating mechanical forces to cause imbalances.
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.
Our 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

Quick Answers
Frequently Asked Questions
What is a rotary screw compressor and how does it work?
A rotary screw compressor uses two interlocking helical rotors (screws) to compress air efficiently. As air is drawn into the screw chamber, it gets trapped and compressed as the screws rotate. This continuous motion allows for a consistent air supply with minimal vibration and high energy efficiency.
What are the benefits of using a rotary screw compressor over a piston compressor?
Rotary screw compressors offer a 100% duty cycle, run at lower noise levels, and have fewer moving parts, which reduces maintenance. They’re ideal for continuous industrial use, unlike piston compressors which are better suited for intermittent tasks.
What is the difference between oil-free and oil-injected screw compressors?
Oil-injected screw compressors use oil for cooling and sealing, making them more durable for heavy-duty tasks. Oil-free compressors, on the other hand, avoid oil contamination and are typically used in sensitive industries like food, medical, or pharmaceuticals.
Should I choose a fixed speed or variable speed (VSD) screw compressor?
Fixed speed compressors run at a constant RPM, making them ideal for operations with consistent air demand. VSD compressors adjust their motor speed based on air demand, helping reduce energy consumption – ideal for businesses with fluctuating usage.
Do you supply and service rotary screw compressors across South Africa?
Yes, Airpower supplies, installs, and services rotary screw compressors nationwide. We stock a range of models from USAir 10 to USAir 100 and provide ongoing support, spare parts, and expert advice to keep your system running optimally.
