Systemair Revolution Vector EC Fan

Systemair Revolution Vector EC Fan — Silent, Energy-Efficient Extraction for Indoor Growing

Best for: Growers who want serious extraction performance without the noise, power bills, or compromise on control

The Systemair Revolution Vector EC fan is a frictionless electronically commutated inline extraction fan built after years of intensive research by Systemair, the world's largest ventilation manufacturer. It combines German-engineered durability with EC motor technology that cuts your power consumption in half, operates at whisper-quiet levels, and gives you pinpoint control over airflow in 1% increments. This is proper kit designed specifically for the hydroponics industry — not a generic fan with a markup.

How it compares

Vector sits in the premium EC fan category, but the comparison to traditional AC fans is stark:

• vs AC fans (RVK, Can-Fan): Uses around 50% less power at the same airflow, operates virtually silently, handles carbon filter resistance without struggling, and lasts significantly longer (80,000–100,000 hours vs 40,000–50,000)
• vs entry-level EC fans (Air EC): Higher build quality, better static pressure for demanding setups, superior noise control options, and German-engineered durability backed by 5-year guarantee
• vs comparable EC rivals (Rhino Ultra Silent): Similar performance envelope; choice comes down to controller ecosystem and acoustic housing preference

Bottom line: You're paying more upfront, but over 3–5 years of running costs, energy savings and longevity typically justify the investment completely.

Usage guidance

Vector EC fans require specific setup and control to unlock their full potential:

Essential controller requirement
All Vector EC fans must be connected to a dedicated EC fan controller (such as G.A.S. Digital EC Controller) that sends 0–10v control signals to the motor. This is not optional — it's how the fan achieves its precision and efficiency. Standard AC fan controllers won't work.

Speed control and energy savings
This is where EC fans genuinely shine. Run the Vector at 60% and it uses 60% of the power. Run it at 30% and power consumption drops to 30%. An AC fan at 60% still pulls nearly full power. If you pair this with a temperature-driven controller, you're essentially automating your energy bill down.

Carbon filter integration
Vector fans generate serious static pressure — they push air through carbon filters without losing performance the way AC fans do. This means you can run larger filters or longer duct runs without the fan struggling.

Sizing your setup
If you're replacing an AC fan, match the diameter and airflow rating (measured in m³/hr). Make sure your carbon filter can handle the maximum airflow output. For noise-critical setups, consider the Silenced V2 variant and run a slightly larger fan at lower speed — quieter and longer motor life.

Noise performance
Even the standard Vector is remarkably quiet. Add the acoustic foam housing (Silenced V2) and pair it with proper phonic trap ducting, and you're looking at whisper-quiet extraction. This matters if noise bleed is a concern.

Technical specifications

• Motor type: Electronically commutated (EC) — frictionless, brushless DC with AC voltage conversion
• Power consumption: Approximately 50% less than equivalent AC fans at comparable airflow; scales linearly with speed setting (1%–100%)
• Speed control: 1% to 100% in 1% increments via compatible EC controller (requires 0–10v input signal)
• Airflow: Varies by model size (4", 6", 8" options available); check specification sheet for your chosen diameter
• Static pressure: High-performance impeller and guide vanes deliver exceptional pressure for filter and duct resistance
• Noise level: Ultra-silent operation; further reduced with Silenced V2 acoustic foam housing (up to 50% noise reduction vs standard variant)
• Housing: Fully sealed composite casing (prevents air bypass around filters); optional acoustic foam lining available
• Build quality: German-engineered; maintenance-free operation
• Warranty: 5-year guarantee
• Lifespan: 80,000–100,000 operating hours (approximately double traditional AC fans)

Who this is for

• Growers running medium to large spaces where extraction is non-negotiable
• Anyone serious about long-term energy cost reduction (payback typically under 2 years)
• Setups where noise discretion matters — residential or semi-urban locations
• Growers already invested in G.A.S. ecosystem products (seamless controller integration)
• Operations running multiple extraction fans (splitter leads allow one controller to manage several fans)
• Experienced growers who want pinpoint environmental control without compromise

Not ideal if you need plug-and-play simplicity or have severe budget constraints — you'll need to factor in the cost of a compatible EC controller, and the upfront investment is higher than AC alternatives.

Our take

This is a properly engineered extraction fan, not a rebadged industrial unit. The EC motor technology delivers on its promises: genuine power savings, real noise reduction, and control that actually means something. Yes, it costs more than an RVK, but if you're building a serious growing setup, this is where your money goes.

Particularly worth picking up if you're replacing worn-out AC kit or setting up a permanent space. Does exactly what it should, day in, day out. Good time to buy while clearance stock lasts.
