Pure Fan Inline 100 Extractor – Silent 107 m³/h Ventilation

The Pure Fan Inline 100 Extractor is the compact and efficient ventilation solution designed to renew the air in your indoor crop or act as an intake fan in larger systems. Its main benefit lies in its ability to move 107 m³/h with minimal energy consumption, ensuring your plants breathe fresh air without raising your electricity bill.

Is your grow tent turning into a sauna where the air feels heavy and stagnant? Before having a device like this, you've probably noticed that temperature pockets form, humidity spikes dangerously after watering, and your plants look "sad" because they lack CO2. Relying on passive ventilation or weak fans often leads to inconsistent environments where pests and fungi thrive.

This situation is a ticking time bomb for your harvest. Stagnant air is the number one enemy of dense buds; it invites mold (botrytis) and slows down photosynthesis, stressing your girls and reducing the final weight of the yield. It's frustrating to invest in lights and fertilizers only to have the environment fail you due to poor circulation.

The solution is simpler than you think. By installing the Pure Fan Inline 100, you ensure a constant and active flow of air. Whether you use it to extract heat from a small closet or to inject fresh air (intraction) into a larger room, this device balances the climate parameters, allowing your plants to focus on fattening up rather than surviving.

Before installing your ventilation system

Before you start plugging things in, you need to plan your airflow strategy. This extractor is axial, which means it's great for moving air with low resistance. If you have a small Grow tent (e.g., 60x60cm or 80x80cm), it can work as your main extractor. For larger setups, it's the perfect intractor to bring fresh street air in.

• Check the diameter: Ensure your ducts and flanges are 100 mm (4 inches).
• Define the direction: Look at the arrow on the casing; it indicates where the air flows. Don't install it backwards!
• Plan the placement: Ideally, place it at the bottom of the tent if used as an intractor, or at the top if used as an extractor.
• Prepare the connection: It comes ready to plug in, but make sure you have an accessible socket nearby.

During use in your indoor grow

Once running, the first thing you'll notice (or rather, won't notice) is the noise. It operates quietly, which is key if you have your setup near a bedroom. With a speed of 2300 rpm, it creates a steady breeze that eliminates hot spots under the lamp. You should monitor your thermohygrometer; you'll see how the temperature stabilizes and relative humidity drops to safer levels.

If you are using it in a long circuit of Air Extraction System ducts, this fan acts as a "booster," giving that extra push needed for the air to reach the end of the line without losing pressure. It's a workhorse that consumes only 15W, so you can leave it on 24 hours a day without worrying about the electric bill.

After: results and maintenance

When you finish the cycle, the difference is obvious: healthier plants, stems that have grown stronger thanks to air resistance, and flowers free of fungal problems. A good climate equals a heavy harvest. Regarding maintenance, the Pure Fan Inline 100 is very grateful. It doesn't require oiling or complex adjustments.

You just need to check the blades after each harvest. Dust and resin tend to accumulate there, which can reduce the 107 m³/h flow over time. A simple wipe with a cloth is enough to keep it running at 100% for the next round. If you used it with an Odor eliminator for weed (carbon filter), check that the connection is still tight.

Short- and long-term advantages and benefits

• Immediate climate control: Reduces temperature and regulates humidity from minute one.
• Energy efficiency: At 15W, it consumes less than a standard light bulb.
• Versatility: Works as a main extractor in mini-tents or as an intractor in large rooms.
• Easy installation: Plug & Play, no tools required.
• Stealth: Silent operation for discreet crops.
• Durability: Robust design meant to run non-stop during the whole cycle.

Frequently Asked Questions

Is this extractor noisy?

Not at all. It is designed to be very quiet compared to industrial turbines. You will hear the air moving (wind noise) more than the motor itself.

Can I use it with a carbon filter?

Yes, but keep in mind it is an axial fan. It works best with small, lightweight filters or in setups where the duct run is short. For heavy-duty filtration in large tents, we recommend using it as an air intake (intractor) to support a more powerful radial extractor.

Does it come with a plug?

Yes, it is ready to plug into the mains (220V - 240V) and start working immediately.

Is it suitable for drying rooms?

Absolutely. It provides the gentle and constant airflow needed to dry your buds slowly without drying them out too fast, preventing mold.

Personal Experience of Pevgrow’s CEO (Alan)

"I always recommend having one of these handy, even if you already have a big extraction system. In my personal setup, I use the Pure Fan Inline 100 as an active intractor. Why? Because by forcing fresh air in at the bottom of the tent, I create a much more efficient current that pushes heat up towards the main filter. It's the cheapest way to drop the temperature by a couple of degrees in summer. Also, for my small mother plant cabinet (60x60), it's the only fan I use, and it works like a charm."
