EC Fans
In short: 24 series (93 models) cover 300–29,000 m³/h, up to 1010 Pa static pressure for EC Fans.
An EC fan couples a brushless PMSM motor to a built-in inverter, so the fan controls its own speed from a 0-10 V, PWM or Modbus signal. Against a shaded-pole or PSC AC motor, an EC fan typically cuts input power by 30–50 % at the same duty point and holds airflow as static pressure rises.

Typical applications
- Air handling units and fan coils running continuously.
- Refrigeration and heat-pump units with part-load operation.
- Data-center and telecom cooling with remote speed control.
- Any installation where duct pressure or filter load changes over time.
How to choose
Specify the control signal your BMS already sends — 0-10 V, PWM or Modbus RTU — and confirm the minimum speed: EC motors run far below AC minimums, which is where part-load savings appear.
