VENTILATION & EXTRACTION

TT 125mm Extractor Fan: two speeds to take control of your grow room air

The Vanguard Hydroponics TT 125mm inline fan moves 220 or 280 m³/h depending on the speed you select, so you can match airflow to what your plants are actually doing. Run it quietly at 23 W through vegetative growth, then switch to full output at 37 W when flowering brings heat and odour. It uses the standard 125 mm duct diameter, measures a compact 240 x 195 mm and is built to work alongside an activated carbon filter. BloomLED has been supplying indoor growers for over 10 years — this is our go-to fan for tents between 0.6 and 1.2 m².

280m³/h peak airflow

23W on low speed

125mm duct size

29dB at its quietest

🌬️ Two speeds you will actually use

220 m³/h on low, 280 m³/h on high. The gap is wide enough to cover a calm vegetative phase and then a hot, pungent flowering period, without ever needing to buy a second extractor fan.

⚡ Just 23 W on the low setting

Low speed draws only 23 W, and the fan never exceeds 37 W. Across a 12-hour daily cycle that is a rounding error next to your grow light — which matters when the fan runs around the clock.

🔇 Down to 29 dB in operation

The AC motor tops out at 36 dB on high and drops to 29 dB on low. Paired with flexible ducting and anti-vibration mounts, it stays discreet enough for a spare room or a home grow cupboard.

🔧 125 mm: the growshop standard

125 mm is the most common size in indoor growing: aluminium ducting, activated carbon filters, speed controllers and reducers all fit straight on, no adapter needed. At 1.8 kg it hangs from a pair of straps with ease.

How large a grow tent can this TT 125mm fan ventilate?

At 280 m³/h on high it delivers the recommended 30-60 air changes per hour in spaces of 0.6 to 1.2 m² — typically an 80x80, 100x100 or 120x60 cm tent. For anything larger, step up to a 150 mm model.

Can I run it with an activated carbon filter?

Yes, the fan is designed for it. Use a matching 125 mm filter and allow for roughly 20% pressure loss. Running on the high setting comfortably absorbs that extra resistance.

How do I make the setup even quieter?

Hang the fan on elastic straps instead of bolting it down, fit acoustic ducting and run it on low overnight. This model has no acoustic housing, so choose a TT Silent version if near-silence is the priority.

The right balance of airflow, power draw and noise for an 80x80 or 100x100 cm tent: 280 m³/h when you need it, 23 W the rest of the time.
