Mountain Air Whisper Fan 250 mm - 1808 m3/h, metal fan with EC motor

The Mountain Air Whisper Fan with a maximum output of 1808 m3/h is designed for 250 mm diameter ducts. The metal soundproof fan is equipped with a high-performance EC motor that guarantees high performance and long life. A digital speed controller with temperature sensor and a total of 3 modes are included. The fan power can be controlled manually or automatically according to the temperature (speed reduction or shutdown) using a simple controller.

The dual impeller and turbine-shaped inlet are designed to optimize pressure throughout the Mountain Air fan housing and improve airflow. Especially when paired with long or complex ductwork. The EC Whisper High Speed fan delivers class-leading performance with its insulated housing, while remaining nearly silent even at full power.

Key Features of the Mountain Air Whisper Fan 250 mm:
- High performance and extra quiet operation
- Ideal for ventilation systems with shorter duct lengths
- Optimized pressure in the fan housing improves airflow
- Fan comes with an external digital speed controller

6 reasons why an EC motor fan is worthwhile?
- Running of electronically commutated motors is smooth and noiseless
- EC motor fans are significantly quieter and operate at lower operating temperatures, they do not overheat
- compared to brush motors, DC EC motors have a significantly longer lifetime
- small EC motor fans can match the extraction performance of larger AC motor fans
- the electronically controlled stator ensures efficient performance and easier control
- the advantage is also greener power distribution, economical consumption and rapidly more efficient performance

The product does not include a power cord for the socket, we recommend adding a 2 metre EU power cord - IEC female.
