Systemair Revolution Vector V2 EC Fan (Silenced) - Quiet, Efficient Inline Extraction
Best for: Growers who need serious extraction from a tent or grow room but can't have a fan roaring away next door.
Our thoughts
Systemair make proper industrial ventilation kit, and it shows the moment you switch this on. The EC motor and acoustic foam housing genuinely take the edge off compared to a standard AC duct fan, without sacrificing pull. It's not the cheapest fan on the shelf, but it's built to run hard for years, and that's worth paying for on a piece of kit your whole grow room depends on.
The Revolution Vector V2 Silenced is an inline duct fan from Systemair, built around a frictionless EC (electronically commutated) motor rather than the older AC shaded-pole motors most budget fans still use. EC motors run cooler, draw roughly half the power of an equivalent AC fan at the same airflow, and give you smooth, stepless speed control rather than a handful of fixed settings.
The "Silenced" housing wraps the motor and blade assembly in sound-absorbing foam developed specifically for ventilation ducting - it won't soak up moisture or dust like household acoustic foam, so it keeps working in a humid tent long-term. Double-balanced blades reduce vibration further. It's sold across five duct sizes (6" to 12"), with the 6" model moving in the region of 764 m3/hr; airflow scales up through the range as duct diameter increases, so pick the size that matches your tent volume and carbon filter.
How it compares
Sits at the premium end of the inline fan market, priced against other EC options rather than bargain AC fans.
- Versus AC Infinity's Cloudline range (a popular budget-friendly EC fan, e.g. the T4 at 205 CFM / 28 dBA): the Cloudline is cheaper and comes with a plug-in speed controller, but the Systemair's industrial-grade motor and acoustic housing are built for continuous heavy-duty use rather than hobby tents.
- Versus standard AC-motor RVK-style duct fans: those need an external variac or speed controller (commonly £100+) to run quietly at lower speeds, and hum noticeably even then. The Vector V2's EC motor gives stepless control and the silenced housing without extra hardware.
- Versus unsilenced EC fans in the same Systemair range: the Silenced housing adds bulk and cost but knocks a meaningful amount off perceived noise, worth it in bedrooms, lofts or anywhere close to living space.
You're paying more than for a basic AC fan, but you're buying quieter running, lower power draw and motor longevity that a cheap fan won't give you.
Usage guidance
Straightforward to install like any inline duct fan - a few things make a real difference to noise and performance.
Sizing
Match duct diameter to your carbon filter and tent size rather than buying oversized "for headroom" - an oversized fan run on low is often noisier and less efficient than a correctly sized fan run at a moderate speed.
Mounting
Suspend the fan rather than resting it on a shelf, and use rubber mounts or hanging straps to stop vibration transferring into the tent frame or ducting, which is often the biggest source of perceived noise.
Ducting
Pair with insulated or acoustic ducting (such as Vortex Ultra Silent ducting) rather than plain flexible ducting to keep the whole extraction run quiet, not just the fan itself.
Speed control
Run with a compatible EC speed controller so you can dial airflow back during quieter overnight periods and up during lights-on when heat and humidity peak.

Who this is for
- Growers running a tent or small room where fan noise matters (bedrooms, converted lofts, shared houses)
- Anyone upgrading from a noisy AC duct fan who wants lower running costs and quieter operation
- Growers who already run EC speed controllers and want a fan that pairs with them properly
- Commercial or multi-tent setups that need extraction that will run reliably day in, day out
Best suited to growers who've outgrown a basic AC fan and want extraction they won't need to think about again.
Our take
This is proper Systemair engineering rather than a budget rebrand - the EC motor and silenced housing are genuine upgrades over a standard duct fan, not just marketing. It costs more upfront than an AC alternative, but the lower power draw and quieter running pay that back over time, especially if the fan is running most of the day.
Does exactly what it should, day in, day out. Pick the duct size that matches your setup and it'll be the last extraction fan you need to buy for that room.
