FFU EC Centrifugal Blower Fan Back Curved For Houses / Buildings Ventilation
| Type | Nomual voltage (VAC) | Frequency (HZ) | Speed (rpm) | Power imput (w) | Curreng draw (A) | Sound pressurelevel (dB) | Sound pressurelevel (dB) |
| LD310C-230D3-03 | 230 | 50/6 | 2200 | 320 | 1.4 | 62 | -20~+60 |
Sustainable speed control benefits to achieve low operating costs, reduce CO2 emissions protect the environment, enable the direct, simple communication between the host controller and the system,
Variable speed control of EC fan can be realized / achievedvia 0-10V speed adjustment and/or external circuit impulse modulation
Constant torque ,constant speed and constant airflow of EC fan can be fulfilled via 180,sine SVPWM(Space Vector PWM)to meet customer needs
Permanent-magnet brushless DC motor within the rotor
The stator is driven by electronic switches (which replace the Carbon brushes), controlled by a microcontroller.
Electronic system (hall effect sensor or software is used to recognize the rotor position
EC operated (230Volts Single phase or 380/480Volts , 50/60Hz)
Pressure control : A pressure sensor can be connected directly to the Electronic of the EC motor. The pressure control is made by the integrated electronics. No additional control unit is needed. (Rosenberg Versions only)
How do I know which model I should choose
Please tell us the fans pressure and ofan and size of fans’ diameter you need. We will study and suggest you the right model.
Can we buy a sample for testing?
Sure, you are welcomed to buy a sample before mass order
