PWM CONTROL FANS
The system utilizes high-performance DC motors controlled by PWM
(Pulse Width Modulation). This technology allows the fan to operate
smoothly at extremely low RPM speeds without generating motor or
electromagnetic noise.
Additionally, the fans feature blades designed with a high static pressure
rating, making them perfect for applications where airflow is restricted,
such as through ductwork. The motor housing allows the fan system to be
mounted either horizontally or vertically.
INSTALLATION GUIDE
STEP 1
Choose a mounting location free of obstructions (e.g., studs, waterlines,
electrical cords, etc.). Ensure the wall is 3.5 to 6.2 inches thick.
Place the front faceplate stencil over the center point, then mark the
mounting points and circular outline.
Before opening the hole, pay attention to the installation position of the
product and the connection distance of the power supply.
STEP 2
Drill the mounting holes into the wall. Use a saw or other tool to open the
center hole and ensure that the hole is circular.
