TT Silent M150 Silent Extractor Fan Ø150mm — Thermostat & Speed Controller

TT Silent M150 Extractor Fan: quiet, intelligent ventilation for your indoor grow

Built for demanding growers, the TT Silent M150 extractor fan combines a 555 m³/h airflow, an acoustically insulated housing and automatic regulation through a built-in thermostat and speed controller. It is the beating heart of a healthy grow tent, where air moves constantly without any noise nuisance.

In indoor growing, ventilation matters just as much as lighting. Without constant air renewal, heat builds up, humidity climbs and your plants begin to suffocate. The TT Silent M150 extractor fan was engineered to solve this for good: it draws hot, stale air out of your grow room while letting fresh, CO₂-rich air flow back in — the essential condition for vigorous vegetative growth and a generous flowering stage. Proper air exchange also keeps the vapour-pressure deficit in the right window, helping your plants transpire and feed efficiently through every cycle.

Its defining feature is the acoustic housing. The motor is fully enclosed inside a box lined with sound-absorbing foam that dampens vibration and muffles the rush of air. Where a bare extractor can be heard across the whole room, the TT Silent M150 stays discreet — even installed in a cupboard, a bedroom or a living space. You get powerful extraction without turning your home into a plant room.

This fan does not just ventilate, it regulates. Thanks to its 4-metre temperature probe and integrated thermostat module, it continuously reads the climate inside your tent and adjusts its output automatically. When the temperature rises above the ideal threshold, extraction speeds up; as the air cools, it slows down. The result is a stable microclimate, day and night, with no manual intervention required.

The electronic speed controller completes the package. It lets you dial in exactly the airflow your setup needs, between 405 and 555 m³/h, depending on the volume of your tent and the growth phase. During vegetation a moderate flow is enough; in full bloom, when heat and odours increase, you simply turn up the power. This flexibility makes the TT Silent M150 a versatile extractor that suits beginners and experienced cultivators alike.

On efficiency, the TT Silent M150 is remarkable: it draws only 45 to 52 watts for a peak airflow of 555 m³/h. Designed to run around the clock, it is rated for a 40,000-hour service life — several years of intensive use. Paired with a Ø150 mm activated carbon filter, it also neutralises odours, for a fully controlled and discreet indoor grow. A reliable investment, hand-picked by BloomLED among the best ventilation solutions on the market.
