Bathroom Extract Fan
SILENT DUAL

Autonomous and intelligent extractor fan for the bathroom, delivering high performance and very low noise.
It automatically adjusts its performance to the ambient conditions and ventilation requirements via a presence detection sensor and a humidity sensor.
Incorporates an intelligent control algorithm to automatically adjust the settings according to the ambient conditions, without the need for user interaction.
Learns from its environment (ambient conditions) and operates accordingly.
Motor with ball bearings and integrated thermal protection, mounted on silent-blocks to reduce vibrations and noise.
The motor regulates its speed to achieve the required flow rate, minimising consumption and noise levels to meet the exact ventilation requirement.
High quality ABS plastic. 
Electrical safety certification according to IEC 60335-1 & IEC 60335-2-80 issued by a notified body.
Direct two-wire connection (L, N).
