The fan is built with a powerful EC (Electronically Commuted) motor, which delivers consistent and reliable performance. It can achieve airflow rates of up to 140 m /h (4945.47 CFM) at a static pressure of 10 Pa, making it suitable for larger bathrooms or spaces with challenging ventilation requirements. The motor's EC technology also ensures low energy consumption, with a maximum power input of 55 W.

One of the standout features of the SQN91.140B2790 is its Quietmark SQ rating, which guarantees a sound level of only 19 dB(A) when operating at low speed. This quiet operation makes it an excellent choice for bathrooms where noise levels are a concern.

The fan comes with a pre-installed humidity sensor, enabling it to automatically adjust its speed based on the bathroom's humidity levels. This not only ensures effective moisture removal but also helps maintain a comfortable bathroom environment. Additionally, the fan features a variable speed control, allowing users to manually adjust the fan speed to their preference.

The Siemens SQN91.140B2790 is designed with a modern, sleek look, featuring a flat, flush-mounted grille and a compact, slimline design.
