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

Product detailed description

The Mountain Air Whisper Fan duct fan with a maximum output of 1808 m3/h is designed for ducting with a diameter of 250 mm. The metal silenced fan is equipped with a high-performance EC motor, which guarantees high output and long service life. The package includes a digital speed controller with a temperature sensor and a total of 3 modes. The fan output can be controlled using the simple controller manually or automatically according to the temperature (speed reduction or switch-off).

The double impeller and turbine-shaped inlet are designed to optimise pressure throughout the Mountain Air fan housing and improve airflow. Especially when paired with long or complex ducting. The high-speed EC Whisper High Speed fan delivers top-class performance in its category thanks to its insulated housing, while remaining almost silent even at full power.

Main advantages of the Mountain Air Whisper Fan 250 mm:
- high output and extra quiet operation
- ideal for ventilation systems with shorter lengths of air ducting
- optimised pressure in the fan housing improves airflow
- the fan is supplied including an external digital speed controller

6 reasons why a fan with an EC motor is worthwhile?
- starting electronically commutated motors is smooth and silent
- fans with an EC motor are significantly quieter and operate at lower running temperatures, they do not overheat
- compared with brushed motors, DC EC motors have a significantly longer service life
- small fans with an EC motor can match larger fans with AC motors in extraction performance
- the electronically controlled stator ensures efficient performance and easier regulation
- another advantage is more environmentally friendly power distribution, economical consumption and rapidly more efficient performance

The product does not include a power cable, we recommend purchasing a Power cable with EU plug - IEC female, 2 metres long.
