Centrifugal Fan

EC133 Backward-Curved Centrifugal Fan — 450 m³/h

EC IP54

Product Overview

The BC133A-E072D1-01 is a high-efficiency EC backward-curved centrifugal fan rated for 450 m³/h airflow and up to 500 Pa static pressure. Its EC motor delivers precise, energy-saving speed control (0-10V/PWM, 3-speed). The backward-curved impeller maintains high efficiency against duct system resistance.

  • Compact industrial housing (IP54)
  • Long-life NSK ball bearings

Applications

The core advantages of EC/DC/AC backward-curved centrifugal fans are: high static pressure, high airflow, adjustable speed, energy efficiency, low noise, and suitability for continuous operation. Therefore, they are mainly used in HVAC and industrial ventilation scenarios that require ducted air supply, variable air volume control, and overcoming relatively high system resistance.
