Rotary Screw Air Compressors
What is a rotary screw air compressor?
Rotary screw air compressors are a type of air compressor that compress the air in a space formed between two rotating screws rotating in opposite directions. It operates by pulling air into the compressor through an inlet, where the screws rotate and compress the air between them. As the screws continue to rotate, the compressed air moves along the screws’ grooves and gets pushed towards the outlet. This process creates a continuous flow of compressed air. They are compact, reliable and energy efficient.
Unlike piston compressors, in rotary screw air compressors, there are no valves or other mechanical forces that can cause unbalance. This allows a rotary screw air compressor to operate at high speeds while combining a large flow rate with small exterior dimensions. The ideal applications of rotary air compressors are continuous, workplace and industrial applications. There are two primary versions, oil-free and oil-injected, with options of fixed speed or variable speed drive operation.
Advantages of Rotary Screw Air Compressors
When you require a constant demand for air, rotary screw compressors provide the perfect solution.
The advantages of a rotary screw air compressor include:
- No valves or mechanical forces: Unlike piston compressors, rotary screw compressors do not have valves or other mechanical forces that can cause imbalance, resulting in smoother and more efficient operation.
- Low Maintenance – With no pistons, bushings, connecting rods, or other parts that require regular maintenance, a screw compressor requires very little maintenance.
- Low noise and vibration levels – Compared to other compression technologies, a screw compressor has fewer moving parts and is smaller in size.
- High operating speeds: Rotary screw compressors can operate at high speeds, allowing for increased productivity and faster compression compared to other types of compressors.
- Large flow rate: Screw compressors can provide a large flow rate of compressed air, making them suitable for applications that require a continuous and abundant supply of compressed air.
- Compact size: Despite their high flow rate, rotary screw compressors have relatively small exterior dimensions, making them space-efficient and easier to integrate into different workplace and industrial settings.
- Versatility: Rotary screw compressors come in two primary versions: oil-free and oil-injected. They also offer options for fixed speed or variable speed drive operation, allowing for flexibility in meeting specific application requirements.
Overall, these advantages make rotary screw air compressors well-suited for continuous, workplace, and industrial applications.
