Pure Fan TT 100 Extractor – Dual Speed Inline Fan for Indoor Growing

The Pure Fan TT 100 Extractor is the mixed-flow ventilation solution you need to keep your indoor crop fresh, odorless, and under control. Designed for 100mm ducts, this fan combines the power of a centrifugal extractor with the silence of an axial one, ensuring your plants breathe perfectly without waking up the neighbors.

Is your grow tent becoming a sauna?

One of the biggest fears for any grower is opening the tent and feeling a wave of heat and stagnant humidity hit their face. If the air doesn't circulate properly, your plants stop breathing, photosynthesis slows down, and the dreaded fungi appear. Are you really going to risk months of work and expensive electricity bills for not having proper airflow?

Ignoring ventilation is the fastest way to ruin a harvest. Heat stress produces airy, weak buds, and high humidity is a magnet for botrytis and powdery mildew. There is nothing more frustrating than having to throw away your flowers because of mold that could have been prevented. Plus, a noisy, low-quality fan destroys the discretion of your setup, turning your hobby into a source of anxiety.

The Pure Fan TT 100 Extractor is the definitive solution for small and medium-sized spaces. Thanks to its mixed-flow technology, it moves a large volume of air with enough pressure to work with carbon filters, but with a much lower noise level than conventional turbines. It gives you the control you need to maintain the perfect VDP (Vapor Pressure Deficit) and ensure rock-hard buds.

Why this extractor is actually worth it for you

If you are growing in a closet or a tent up to 1m², you don't need an industrial turbine that sounds like a jet engine. You need efficiency and balance. The Pure Fan TT 100 offers exactly that: a professional performance/price ratio. It allows you to renew the air effectively without consuming excessive energy (max 33W), keeping your overhead costs low.

It is especially useful for growers who live in apartments or shared spaces where silence is gold. Its ability to switch between two speeds allows you to adapt the power: use the low speed for the vegetative phase or winter nights, and switch to high speed during flowering or hot summer days. It is a versatile tool that grows with your plants.

Most important features and benefits

• Dual Speed (145 / 187 m³/h): Gives you total flexibility. You can save energy when the plants are small and increase power when they need maximum transpiration.
• Mixed Flow Technology: Combines axial and centrifugal movement. This means it has enough pressure to push air through an Odor eliminator for weed without losing flow, unlike basic axial fans.
• 100mm (4") Diameter: Standard size compatible with most ducts, cooltubes, and filters on the market. Easy to find accessories.
• Maintenance Free: Designed to run continuously 24/7 without you having to grease or open it. Install it and forget it.
• Easy Access for Cleaning: The central body can be removed without dismantling the ducts, making cleaning a breeze between harvests.
• Low Consumption (21W / 33W): Efficient operation that won't spike your electricity bill, allowing you to invest that money in better genetics or nutrients.

Typical objections and clear answers

We know that choosing the heart of your ventilation system generates doubts. Here we clarify the most common ones:

• You think that it might be too noisy for a bedroom. In reality, while no fan is silent, the TT series is significantly quieter than RVK or VK types of the same power. If you use insulated ducting, it becomes barely perceptible.
• You think that it won't be powerful enough for a filter. In reality, the TT design is specifically made to handle the static pressure of a carbon filter, unlike basic inline fans that choke immediately.
• You think that it's difficult to install. In reality, it comes ready to be inserted into the ducting or attached to the wall/ceiling with its integrated bracket. It's plug-and-play.

How to use it safely and effectively

To get the best performance and extend the life of your Pure Fan TT 100, follow these steps:

1. Strategic Placement: Install the extractor at the top of your Grow tents, as hot air naturally rises.
2. Secure Connection: Use metal clamps or duct tape to hermetically seal the connection between the extractor, the ducting, and the carbon filter. Any leak can let odors escape.
3. Keep the Duct Straight: Try to keep the ducting as straight as possible. Every curve reduces airflow and increases noise.
4. Speed Selection: Use the switch to select the appropriate speed. We recommend starting with the low speed and increasing it if the temperature exceeds 26°C.
5. Don't Turn It Off: During the dark cycle, plants still breathe and humidity rises. Keep the extractor running 24 hours a day to prevent mold.

Frequently Asked Questions

Is this extractor suitable for a 1.20 x 1.20m tent?

It might fall a bit short for that size if you use high-intensity HPS lights. For a 1.20m tent, we usually recommend the 125mm or 150mm model. The TT 100 is ideal for spaces of 60x60cm up to 80x80cm, or as an intake fan for larger rooms.

Does it come with a cable and plug?

Yes, generally these models are ready to connect, but always check the specific contents of the box. Installation is simple and safe.

Can I use a fan speed controller with it?

Yes, although it already has two speeds, you can add an external potentiometer to fine-tune the flow. However, make sure the controller is compatible with AC motors to avoid humming noises.

Personal Experience of Pevgrow’s CEO (Alan)

I have used these TT extractors in countless setups, especially in mother closets and drying tents. What I like most is that they are "battle tanks": you plug them in and they don't fail. I remember a crop in a small apartment where noise was a critical issue; swapping a conventional turbine for this TT 100 made the difference between sleeping peacefully and hearing a constant hum.

My advice: don't skimp on the installation. Use good clamps and, if you can, soundproof ducting. The extractor is good, but a good installation makes it perfect. For the price it has, it is undoubtedly the best option to start with a professional Air Extraction System without spending a fortune.
