Variable Speed Drive (VSD) air compressors are getting more popular in Australia for many industries. Before VSD, we know fixed speed air compressors, where they operate at the same speed every time they run. So All Air Compressors has prepared an article for you to understand the fixed speed and variable speed air compressors.
All Air Compressors is an expert air compressor repairs in Sydney, NSW. We specialise in compressed air servicing and repairs, air piping installation, and also line filter installation.
What Is Fixed Speed Air Compressor?
As the name suggests, a fixed speed air compressor operates at the same speed whenever it’s running. By design, it always draws the amount of power needed to meet the maximum compressed air demand, even if demand is less than maximum. Because the speed of the motor can’t change, whenever the demand for air changes, an air inlet valve adjusts to allow either more or less air to flow out.
Use Fixed Speed Ais Compressor When:
• Demand for compressed air fluctuates little • Upfront cost is a significant consideration
What Is Variable Speed Air Compressor?
In contrast to the fixed speed compressor, a Variable Speed Drive (VSD) air compressor can operate anywhere in the range between its minimum and maximum speed. It automatically adjusts the speed so the production of compressed air matches demands in real-time. When demand increases, the motor speeds up. When demand decreases, the motor slows down. This capability saves energy because the compressor doesn't have to run flat out whenever it’s on. You can think of the variable speed compressor like the accelerator in a car, which allows you to vary the car's speed according to road conditions, level of traffic and whether you’re in a hurry!
Use Variable Speed Drive Air Compressor When:
• Demand fluctuates significantly between jobs • Demand varies by shift, on weekends or seasonally • Manufacturing processes require tight tolerances for operating pressure
Using Variable Speed And Fixed Speed Compressors Together
Sometimes, the most efficient compressed air solution combines one or more fixed speed compressors to provide a base load with one VSD compressor that "trims" to meet changes in demand. A system with multiple smaller compressors instead of one big compressor also provides redundancy that allows you to keep part of your facility operational when a compressor is offline for service or repair. If you're not sure whether you should choose a fixed speed or variable speed air compressor—or a combination of both—our experienced compressed air system engineer from All Air Compressors can help you decide.
