Variable Speed Rotary Screw Compressors
Variable speed compressors maintain a constant air pressure and the motor speed will be adjusted to meet the air demand of your production. Variable speed compressor units can run on 100% flow or can fluctuate to less flow to conserve energy and align with the current air demand.
Fixed Speed Rotary Screw Compressors
Fixed speed compressors run either full throttle or are switched off. These are ideal in applications where there is a constant compressed air demand 24/7. The machine will run at a constant RPM unless turned off. The inlet valve will flutter based on when air is needed or not needed instead of ramping the engine up and down.
Let's Make it Simple:
Variable Speed Benefits
- Reduced energy consumption (in the proper application)
- Quieter than a fixed speed compressoe when running at a lower RPM
- Consistent plant pressure
- Increased component lifetime
- Low inrush current during motor starts
- May qualify for energy incentives
Fixed Speed Benefits
- Lower capital cost
- Increased parts availability
- Lower maintenance and repair costs
- More efficient in applications with a consistent demand
