PP — EC Motor Driven Forward Multi-Blade Centrifugal Fan

Midi Industrial is a renowned Asian manufacturer of HVAC fans and building ventilation fans for engineering projects - engineered to fuse aerodynamics, motor technology and intelligent control.

Most PP fans never leave a terminal device: a fan coil, a compact duct box, a small fresh-air terminal. The scale here is small - wheel 130-180 mm, airflow 100-2,000 m3/h, pressure up to 250 Pa, motor output just 60W-120W. At these levels the fan does not fight long ducts or heavy filter banks; it moves air through short sections inside or behind the terminal unit, quietly and with little power draw.

Control wiring note
The EC motor and controller are one unit, so the terminal does not need a separate drive mounted somewhere in the ceiling void. Control signals are VSP/PWM/485, matching fan coil controllers, thermostats and small ventilation boards that adjust speed by room demand. Insulation grade B and working temperature -25 C-60 C cover the indoor and light-duty environments these units live in. Keep the 250 Pa pressure limit in mind: if the terminal adds a long run of ducting or a dense filter, size up to a larger series.

Typical fits
Fan coil units and small duct ventilation products are the application listed, used in residential buildings, offices, hotel rooms and light commercial spaces. During selection, check the terminal's available depth and mounting flanges first; power draw at this size makes the fan easy to add to an existing terminal controller.
