Systemair Revolution Stratos AC Fan

German-built AC extraction that moves serious air quietly

The Systemair Revolution Stratos AC Fan is a high-output inline extractor trusted by indoor growers for reliable ventilation and low noise. A flow-optimised free-running axial impeller and sealed 230V AC motor push large volumes of air with minimal pressure loss, even pulling through a carbon filter, so temperature, humidity and CO2 stay stable inside a grow tent or grow room. Depending on size it delivers from 439 m3/h up to 4,212 m3/h of airflow, covering everything from a single tent to a full commercial room.

Key Benefits

• Airflow from 439 to 4,212 m3/h across the 150mm to 355mm sizes for tents and grow rooms
• Holds airflow under load - still moves 318 to 2,900 m3/h with a carbon filter attached
• Quiet, low-vibration running from a balanced, flow-optimised plastic impeller
• Sealed motor housing with thermal overload protection for long-term reliability
• Speed controllable - works with any standard AC fan speed controller
• German build quality for consistent output and a long service life

Beat rising heat, humidity and stale air

Weak ventilation lets temperature and humidity climb and air turn stale, which slows vegetative growth, cuts nutrient uptake and invites mould in flower. The Stratos continuously extracts warm, humid air while drawing in fresh CO2-rich air, stabilising the environment for strong transpiration and denser buds; paired with a carbon filter it also scrubs odour without choking airflow.

How to Use

• Fit the fan into your tent or room extraction line, near the top where heat gathers.
• Hang it from the built-in brackets or suspend on straps to isolate vibration.
• Connect ducting and your carbon filter with duct clamps, keeping bends to a minimum.
• Power it through an AC fan speed controller to dial in the right extraction rate.
• Balance intake and extraction to hold slight negative pressure and steady climate.
