Revolution Super Silent High Power AC Stratos Fan

Powerful extraction that stays remarkably quiet

The Revolution Super Silent High Power Stratos AC is the largest AC inline extractor from ventilation specialist Systemair, built to move large volumes of air through a grow room while running extremely quietly. A sealed steel housing with acoustic insulation cuts vibration and noise, while an aerodynamically optimised impeller and guide vanes keep airflow strong even with a carbon filter and ducting attached. It comes in two sizes — 315mm (12") at 3,812 m³/h and 355mm (14") at 4,212 m³/h — sold by G.A.S as 315 Stratos AC and 355 Stratos AC.

Key Benefits

• Powerful airflow up to 4,212 m³/h for grow tents and grow rooms
• Super silenced casing with acoustic insulation to cut operational noise
• Aerodynamically optimised impeller and guide vanes for efficient air movement
• Balanced fan blades reduce vibration and sound
• Sealed steel housing prevents air leaks and holds pressure with filters fitted
• Thermal motor protection guards against overheating
• Durable European AC build for maintenance-free running

Need strong ventilation without disturbing the household?

Heat and humidity build up fast under grow lights, and humidity spikes in flower raise the risk of mould and hurt bud quality. The Stratos removes warm, stale air and draws in fresh air to stabilise the environment, supporting transpiration, nutrient uptake and steady growth through veg and flower — all while staying quiet enough for noise-sensitive spaces even at high airflow.

How to Use

• Install the fan within your extraction system, inside or outside the grow tent or room.
• Mount it securely using hanging brackets or mounting straps.
• Connect to ducting and a carbon filter using appropriate duct clamps.
• Plug into a suitable power source or AC fan speed controller.
• Adjust airflow to hold stable temperature and humidity.
