Durable, Reliable Centrifugal Technology for Your Plant
Our centrifugal compressors ensure steady-state operation through continual acceleration and deceleration, compressing a steady stream of air. As a result, this centrifugal technology consistently produces a high volume of ISO 8573-1 Class 0 oil-free air—the purest possible air as specified by the International Organization for Standardization (ISO)—for all applications.
- 68% Less Downtime
- 26% Savings in Operational Costs
- 15% Less Energy Usage
Centrifugal Compressors: A Breakdown
- Systems Impeller: Designed for lasting endurance and durability; features radial blades; spins at high velocity (50,000+ RPM) to push air outward.
- Diffuser: Slows airflow from the impeller and increases pressure; helps convert kinetic energy into pressure energy.
- Collector: Receives compressed air from the diffuser; guides the air toward the discharge outlet; can feature a volute channel (single-stage) or manifolds (multistage) for balanced airflow.
- Inlet Guide Vanes (IGVs): Control the air that enters the impeller to ensure efficiency regardless of load conditions.
- Coolers: Control temperature of the air throughout each stage, including discharge; intercoolers and aftercoolers work to improve air density, reduce system strain, and aid in moisture removal.
- Casing: Protects internal components of the system and the compressed air within; structurally sound and built to last in high-pressure and high-temperature settings.
How Do Centrifugal Air Compressors Work?
- Air Intake: Air is drawn into the compressor and directed toward the rapidly rotating impeller.
- Velocity Increase: The energy of the spinning impeller forces air out at high speeds, increasing the kinetic energy.
- Pressure Conversion: The forced air reaches the diffuser, decreasing velocity and converting kinetic energy into pressure energy.
- Discharge: The air is discharged from the unit at a continuous rate and pressure.
