Centrifugal & Turbo Blowers

Centrifugal and turbo blowers supply the compressed air required for diffused aeration in wastewater treatment. Unlike positive-displacement (PD) blowers, centrifugal technology accelerates air through high-speed impellers to generate pressure, producing smooth, pulse-free, 100% oil-free air delivery. This eliminates the need for oil filtration systems and the risk of oil contamination of the wastewater or downstream treatment processes.

Two configurations are available. Multistage centrifugal blowers use multiple impeller stages in series to achieve the required discharge pressure, operating without a bull gear and offering reliable, low-maintenance performance across a wide flow range. Single-stage turbo blowers use a high-speed direct-drive impeller with a variable frequency drive (VFD) inverter on the motor, enabling precise flow control that matches blower output exactly to the biological oxygen demand — delivering the largest energy savings of any blower technology.

Turbo blower packages are fully pre-assembled and include the compression unit, blow-off valve, VFD-controlled motor, PLC controller, and HMI interface as standard. The HMI continuously monitors and displays airflow, discharge pressure, motor current, and energy consumption, providing operators with real-time process visibility and enabling automated alarm responses without external instrumentation.
