Centrifugal Fans — Series U/APR 

Compact, high-pressure centrifugal fans for industrial extraction and gas handling applications.

The U/APR series centrifugal fans are designed to handle air and gases, including slightly dusty conditions, at temperatures up to 80 °C. With their compact footprint and high-pressure capability, they are suited for installations where space is limited and reliable performance is required for extraction and process air transport.

The U/APR centrifugal fans are engineered for:

  • Industrial air extraction and ventilation

  • Gas handling and transport in process systems

  • Compact and space-constrained installations

  • Systems requiring elevated static pressure

  • Integration with ducted networks and extraction lines

These fans combine robust construction, high-pressure capability, and compact design to ensure steady, continuous industrial operation.

Applications

Industrial Air Extraction & Ventilation

High-pressure removal • Enclosed spaces

Process Gas Handling

Clean gases • Process air transport

Confined or Compact Installations

Limited space • Optimized footprint

Ducted Systems with High Static Resistance

Reliable performance • Higher static loads

  • High-pressure performance in a compact package
    Designed to deliver increased static pressure while minimizing footprint.

  • Durable industrial construction
    Sturdy steel casing and components built for mechanical strength and continuous duty.

  • Balanced impellers
    Dynamically and statically balanced for smooth, stable, low-vibration operation.

  • Direct drive configuration
    Impeller mounted directly on the motor shaft for efficient power transfer and reduced maintenance.

  • Industrial motors for continuous service
    Asynchronous motors, three-phase or single-phase, typically with IP55 protection and self-ventilation, designed for industrial continuous duty.

  • Operating temperatures up to 80 °C
    Suitable for conveyed air and gases within standard industrial temperature limits.
