The Manrose MF100T is a high-performance, 4-inch (100mm) inline mixed-flow extractor fan designed specifically for long duct runs in bathrooms, kitchens, and wet rooms.
Its "mixed flow" design combines the high volume of an axial fan with the high pressure of a centrifugal fan, allowing it to move air up to 12 metres without losing significant power.
Key Specifications
Performance: Delivers a maximum airflow of 245 m³/hr (68 l/s) on high speed.
Noise Level: Operates very quietly at 24 dB(A) at 3 metres, roughly equivalent to a whisper.
Timer: Features an adjustable overrun timer (typically 1 to 20 or 30 minutes) that keeps the fan running after the light is switched off to clear remaining steam.
Speeds: Offers 3 selectable speed settings (High, Medium, Low) adjusted via an internal dip switch during installation.
Motor: Uses a high-quality ball bearing motor, continuously rated for at least 30,000 hours.
Installation & Design
Placement: Installed in the loft or ceiling void rather than directly in the bathroom, which significantly reduces noise inside the room.
Ducting: Compatible with both rigid and flexible 100mm (4") ducting.
Safety: IP44 or IPX4 rated (moisture resistant) and double insulated, so no earth connection is required.
Maintenance: The fan assembly can be easily unclipped from its mounting cradle for cleaning or replacement without disturbing the ducting.
