Pure Fan TT 125 Extractor – 2 Speeds & 280 m³/h Power

The Pure Fan TT 125 Extractor is the definitive solution to ensure your indoor crop breathes fresh air constantly, acting as the true heart of your ventilation system. This device is not just a fan; it is a high-performance tool designed to extract hot, stale air and renew it, ensuring your plants have the CO2 they need to fatten up without stress. If you are looking for efficiency without complications, this mixed-flow extractor offers the perfect balance between power and consumption.

Is your grow tent turning into a sauna for your plants?

We've all been there: you open the cabinet and a wave of heat and humidity hits your face. That stagnant air is the worst enemy of your crop. When the environment is not renewed, the stomata close, growth stops, and the dreaded fungi (like botrytis or powdery mildew) begin to throw a party on your flowers. You are risking months of work and money on electricity for a harvest that could end up in the trash.

Continuing with poor ventilation is playing Russian roulette with your buds. It's not just about the heat; it's about the lack of oxygen and the accumulation of stale air pockets that prevent your "girls" from eating properly. If you don't act, you will see weak stems, airy buds, and potentially, a total loss due to rot.

The Pure Fan TT 125 Extractor is the immediate remedy to this problem. Thanks to its capacity to move up to 280 m³/h, it sweeps away heat and excess humidity in minutes. By installing it, you ensure a constant flow that keeps the climate stable, allowing your plants to focus on what matters: producing resin and terpenes.

Why this product improves what you already have

If you are still using those cheap plastic axial fans (the ones that look like PC fans), you have probably noticed that they die when you put a carbon filter on them. The Pure Fan TT 125 plays in another league. Its mixed flow technology combines the axial force with the pressure of a centrifugal fan. This means it can push air through ducts and filters without losing its breath, something basic fans simply cannot do.

Compared to heavy industrial turbines, this model is much more friendly for home growers. It is lighter, easier to hang, and consumes significantly less electricity (only 37W at maximum power). Plus, having two speeds gives you the versatility to turn it down during the seedling phase or winter, and crank it up to the max during flowering or summer.

Key features you’ll notice from the very first use

• Dual Speed: Select between 220 m³/h (for maintenance or night) and 280 m³/h (for maximum performance) with a simple switch change.
• 125mm (5") Diameter: Standard size compatible with most ducts and Odor eliminator for weed on the market.
• Easy Maintenance: The motor block can be removed without dismantling the ducts, thanks to its smart clip system. Cleaning it takes 2 minutes.
• Energy Efficiency: With a consumption of 23W to 37W, it is powerful but won't skyrocket your electricity bill.
• Durability: Designed for continuous operation, its motor is robust and does not require greasing or constant revisions.

Who this product is especially interesting for

This extractor is the "Swiss Army knife" of ventilation, ideal for a wide range of growers:

• Growers with 80x80 to 120x120 tents: It has the perfect power to renew the air in these volumes every minute.
• Users looking for discretion: Although no fan is silent, the TT design is quieter than conventional turbines, especially if you use soundproof ducting.
• Those who need versatility: Perfect as a main extractor in small kits or as an active intake fan in larger rooms to support a more powerful Air Extraction System.

How to integrate it into your routine without overcomplicating things

Installing the Pure Fan TT 125 is plug-and-play. You don't need to be an electrician; it comes ready to work. To get the most out of it, hang it at the top of your Grow tents using straps or pulleys to reduce vibrations. Connect the extraction tube to the outlet mouth and direct it towards a window or vent.

If you are worried about the smell, connect a carbon filter to the intake mouth (inside the tent). Remember to seal the joints well with duct tape or metal clamps so that no smell escapes. Set the speed according to the temperature: if you see the thermometer go above 26°C, switch to the high speed (280 m³/h) and relax.

Frequently Asked Questions

Does it come with the cable and plug included?

Generally, these extractors come pre-wired or with a very simple connection system. Check the specific contents of the box, but installation is extremely basic and safe.

Can I use a speed controller with this fan?

Yes, although it already has two integrated speeds, it is compatible with external potentiometers if you need even more precise control of the climate.

Is it very noisy?

It is quite quiet for the power it has, much more so than the VK type turbines. However, for maximum silence, we recommend using soundproof ducting.

Can it work 24 hours a day?

Absolutely. It is designed for continuous work. In fact, for optimal air renewal, it is recommended that it is always on, at least at minimum speed.

Personal Experience of Pevgrow’s CEO (Alan)

I remember when I started, I tried to save money with bathroom extractors and the result was disastrous: heat stress and smell throughout the house. When I switched to the TT range, the change was radical. What I like most about the Pure Fan TT 125 is that it is a workhorse; you plug it in and forget it exists. I usually use it in 1x1 meter tents with a 250W or 300W LED. I keep it at speed 1 during the vegetative stage to maintain humidity, and I switch it to speed 2 as soon as I flip to flowering to lower the humidity and avoid botrytis. It is, without a doubt, the best investment in terms of quality/price for a medium-sized crop.
