Fits 100 / 125 / 150 mm ducting - shaft or duct installation


Silenta fans are designed for straightforward installation in a ventilation shaft or connected to ducting. Choose the right size for your system with compatibility across 100 mm, 125 mm and 150 mm diameters. The clean, modern front design blends neatly into most interiors, while the integrated insect mesh helps keep bugs out. With IP34 protection, the units are well suited for everyday bathroom conditions, and an optional backdraft shutter is available to reduce reverse airflow and draughts when the fan is switched off.

Efficient motor & smart control options: timer, humidity, pull cord


Behind the sleek housing sits a reliable motor engineered for efficiency - starting at just 7 W (100 mm models). Built for maintenance-free continuous operation, each fan includes overheat protection for added safety. Pick the control style that suits your project: Silenta-ST features an adjustable run-on timer (2–30 min), Silenta-STH adds a humidity sensor with adjustable switching point (60–90% RH), Silenta-SV uses a pull cord, SVT combines pull cord + timer, and SVTH combines pull cord + timer + humidity sensing. Manual control can also be set via a wall light switch (not included) or upgraded with the optional BU-1-60 electronic control unit. Mounting is flexible: direct shaft fitting, screw fixing to the wall, or even ceiling installation. If the fan is positioned away from the shaft, flexible ducting can be used and secured with a hose clamp for a tight connection.
