Product Overview

The Manrose FLAT100H is a slim, low-profile 100 mm (4-inch) axial fan that’s specially designed for bathrooms and washrooms. With a depth of just 15 mm, it can be recessed neatly into panels or walls, giving a discreet, almost flush finish. The casing is made from white, high-gloss ABS plastic, making the unit both durable and easy to clean.

What sets this model apart is its built-in humidistat, which means the fan will automatically switch on when the relative humidity increases — for example, during or after a shower — and then turn off once steam levels drop. The humidistat is a clever way to prevent condensation and mould, without needing to rely on a separate switch or manual control.

In terms of performance, it delivers an extraction rate of around 95 m³/h (26 L/s), while running at a very quiet noise level of 38 dB(A). It’s IP44-rated for protection against moisture, operates on 220-240 V AC, and consumes about 14 W, making it an energy-efficient solution for maintaining fresh air in a humid bathroom environment.
