Envirovent 4 Inch Inline Extractor Fan + Timer

Envirovent Ultra Quiet Micro Inline Fan with Timer
ENV SILMV160/100T

The Envirovent Silent MV is a one of the quietest and small high power mixed-flow inline fans available.
Manufactured in a highly durable plastic with a specially designed internal skin that will direct any noise into a sound-absorbent insulation material. It features rubber gaskets on the inlet and outlet to absorb vibrations.
The SILMV/160T has a 2 speed, low energy, high power motor which delivers a maximum extraction of 180m m3/hr at a near silent 24dBA. Once installed you won't even know this fan is there. Fitted with an integral overrun timer which can be adjusted between 2-25 minutes.
The main body of the fan can be rotated in its mounting bracket whilst the cable connection box can be rotated through 360° to ensure it can be fitted in even the tightest of spaces.
