150mm Soundproof Box: bring real silence to your indoor grow

Is your 150mm extractor fan too loud at night? The BloomLED soundproof box wraps your fan in a high-density acoustic-foam enclosure, killing vibrations and turbulence noise so you can grow without keeping the household awake. Built for serious growers, this box delivers a measurable noise reduction of up to -15 dB while keeping your airflow virtually unchanged.

BloomLED 150mm soundproof box for extractor fan

Why soundproof your extractor fan?

A standard 150 mm extractor fan running 24/7 produces between 45 and 60 dB — about as loud as an ongoing conversation or a dishwasher. In an apartment, studio or shared house, that constant hum quickly becomes a problem for you and the neighbours. The professional fix used in recording studios and labs: lock the noise source inside a damping enclosure. That is exactly what this BloomLED soundproof box does.

What sets the BloomLED soundproof box apart

🔇 High-density acoustic foam

30 mm of closed-cell foam line the inner walls, absorbing the mid and high frequencies generated by the fan blades. The result is a near-silent operation at one metre away.

🔧 Tool-free installation

Drop your extractor inside, hook your ducts to the two pre-cut outlets and close the box. No screws, no drilling — everything fits together by hand in minutes.

💨 Airflow stays strong

The generous outlets and straight-through layout cause only a minor pressure drop. Your fan keeps its CFM rating while losing its noise signature.

🌿 Made for discreet indoor growing

In flats, shared houses or noise-sensitive environments, this box is the must-have companion to any grow tent that needs to stay quiet around the clock.

Which extractor fans fit this 150mm box?

Any centrifugal or axial extractor with a 150 mm round outlet — including thermo-controlled Secret Jardin units, the TT Silent series and Vent Quietline models. Just check the external dimensions of your fan before ordering.

How much noise reduction will I really see?

BloomLED bench tests show a reduction between -10 and -15 dB depending on the fan model, the airflow setting and the duct connections. To squeeze out every decibel, pair this box with insulated ducting (Combi-Connect) and anti-vibration hose clamps.

Does the foam need any maintenance?

No. The acoustic foam is treated to handle the humidity inside a grow tent. A gentle vacuum with a brush attachment once or twice per cycle is all it takes to keep the box performing at its best.

Paired with a silent 150 mm extractor, this box turns your ventilation system into a near-inaudible setup — the BloomLED signature, trusted by demanding growers for over 10 years.
