Helical Line Extractor T-125 (190 m3/h) – Silent Inline Fan

The Helical Line Extractor T-125 (190 m3/h) is the most practical, economical and efficient solution to ensure constant air renewal in your indoor cultivation. Designed to fit perfectly into standard ducts, this device guarantees that your plants receive the oxygen and CO2 they need to develop explosively.

Is your grow tent suffering from heat and stale air?

You know the feeling: you open your grow tent and a wave of hot, heavy air hits you. Your plants look droopy, development slows down, and temperature pockets form that can ruin your harvest. Many growers rely on passive ventilation or oversized, noisy fans that consume too much energy for the job required.

If you don't fix this, you are inviting fungi, pests and stunted growth. Stagnant air is the silent enemy of cannabis; without a constant flow, even the best fertilizers won't save your buds. Plus, the noise of a turbine engine running 24/7 can drive you (and your neighbors) crazy.

The solution is simple: the Helical Line Extractor T-125. With a capacity of 190 m3/h, it provides exactly the airflow you need to cool your space or introduce fresh air. It is the logical step to professionalize your Air Extraction System without complications or high costs.

Why this inline fan improves your setup

Compared to heavy centrifugal extractors, this helical model is incredibly lightweight and compact. If you are currently using passive intake (just a hole in the tent), installing this fan as an intractor will actively force fresh air in, lowering the temperature much faster and creating a healthy airflow for the stems.

Furthermore, if you have a long ventilation circuit where the main extractor loses power due to the length of the tube, placing this fan in the middle of the line acts as a "booster," recovering pressure and ensuring that the air effectively leaves the room. It is the perfect complement for your Grow tents.

Key features you’ll notice from the very first use

• 125 mm Diameter: Standard size compatible with most flexible aluminum tubes and Aluconnect ducts.
• 190 m3/h Flow Rate: Perfect power for air intake in medium tents or extraction in small spaces (up to 80x80 cm).
• Silent Operation: Its axial design generates much less noise than turbine extractors, keeping your crop discreet.
• Low Consumption: Designed to run 24 hours a day without you noticing a scare on your electricity bill.
• Easy Installation: It fits directly into the tube or the ventilation sleeve of the closet; you don't need tools or complex supports.

Who is this product especially interesting for?

This fan is a "Swiss Army knife" for any grower, but it is essential for:

• Growers with temperature problems: Using it as an active intractor (bringing street/room air in) lowers degrees more efficiently than just extracting.
• Micro-growers: If you have a small closet or a propagation area, this fan is enough as a main extractor.
• Users with long ducts: Ideal for reinforcing the circuit and preventing air from stagnating in the tubes.

How to integrate it into your routine without overcomplicating things

Getting it up and running is as easy as connecting it to the ducting. Look at the arrow drawn on the casing: it indicates the direction of the air. If you point it inwards, it works as an intractor; if you point it outwards, as an extractor. For total control over the environment, you can connect it to a basic timer or a Climate Control unit to turn on only when the temperature exceeds your limit.

Frequently Asked Questions

Can I use a carbon filter with this extractor?

Technically yes, but we do not recommend it as the main option. Helical fans have little static pressure and lose a lot of power when pulling through a dense filter. For use with a filter, a centrifugal extractor is better. This T-125 is ideal as an intractor or for extraction without a filter.

Is it very noisy?

No, it is one of the quietest on the market in its category. You will hear the sound of the air moving more than the motor itself.

Does it come with a cable and plug?

These industrial type fans usually come ready to connect the cable (check the specific product options or ask us if you need the cable added to your order).

What size grow tent is it good for?

As a main extractor, for spaces up to 60x60cm or 80x80cm with LED lighting. As an intractor (air intake), it is perfect for tents up to 120x120cm.

Personal Experience of Pevgrow’s CEO (Alan)

"I've seen many beginners spend a fortune on huge extractors for small tents, creating a vacuum effect that sucks the walls in. The T-125 is my favorite for balancing the system. I use it in all my setups as an active intractor. It's the cheapest way to drop the temperature by 2 or 3 degrees instantly. If you have a long tube run with bends, put one of these in the middle and you'll see how the flow improves radically. Reliable and cheap."
