Product Overview

The FB3G225-2APY-90 is a 225mm centrifugal blower engineered for high-efficiency ventilation in commercial and light industrial settings. Operating at 230V AC with 73 dB(A) ultra-quiet performance, it delivers 1202 m³/h airflow at 514 Pa static pressure while consuming only 150W. Featuring a compact design with IP44 protection, it excels in applications requiring reliable airflow with minimal noise footprint.


Key Features

  1. Optimized Airflow Efficiency

    • 150W power achieves 1202 m³/h airflow - 25% more efficient than standard 225mm blowers.

  2. Library-Quiet Operation

    • 73 dB(A) noise level (quieter than dishwasher) via aerodynamic 7-blade design and vibration-damped motor.

  3. Wide Voltage Resilience

    • Stable performance across 184-270V AC fluctuations, ideal for regions with unstable grids.

  4. Precision Speed Control

    • Standard 0-10VDC/PWM input + FG tach signal (4 pulses/revolution) for real-time RPM monitoring.


Q&A: Why Choose This Blower?

Q: Is it suitable for noise-sensitive retail environments?
A:  Retail-ready quietness. At 73 dB(A), it meets acoustic standards for stores and cafes without requiring extra silencers.

Q: Can it maintain consistent airflow in variable-temperature settings?
A:  Temperature-adaptive. Operates flawlessly from -25°C to 60°C, ideal for unheated warehouses or rooftop installations.

Q: Does it integrate with building automation systems?
A:  Smart-building ready. PWM control and FG tach output enable seamless integration with BMS controllers for energy optimization.


Typical Applications

  • Commercial HVAC: Boutique store ventilation, restaurant kitchen exhaust

  • Light Industrial: Packaging machine cooling, textile dryer airflow

  • Electronics: Audio amplifier thermal management, projector cooling

  • Agricultural: Greenhouse circulation systems, hydroponics ventilation
