Revolution Silenced EC Duct Fan V2 | Ultra Quiet Systemair Inline Fan

Powerful extraction without the noise

The Revolution Silenced EC Duct Fan V2 is a high-performance inline fan engineered in Germany by Systemair for grows where airflow has to be strong but noise has to stay low. Its acoustic housing and frictionless EC motor pull heat, stale air and humidity out of the tent or room while running far quieter than a standard duct fan. Available from 150mm up to 315mm, it delivers roughly 764 to 2,122 m3/h depending on size, using around half the power of a traditional AC fan.

Key Benefits

• 764 to 2,122 m3/h airflow across the range for tents to full grow rooms
• Efficient EC motor drawing roughly half the power of a comparable AC fan
• Fully sealed, silenced housing that stops air leaks and cuts noise
• Double-balanced blades to reduce vibration and airflow noise
• Maintenance-free, serviceable motor built for long service life
• G.A.S Enviro V2 compatible using a G.A.S EC cable pack for precise speed control
• 2-year manufacturer guarantee

Fixing heat build-up and humidity spikes without a noisy fan

Without proper air exchange, heat from grow lights accumulates, humidity climbs in flower and stale air limits nutrient uptake, yet a standard high-output fan can be loud enough to rule out discreet growing. The Revolution's sealed acoustic housing and sound-dampening foam let it shift large volumes of CO2-rich fresh air with minimal vibration, giving strong extraction, stable temperature and humidity, and better root development without the racket.

How to Use

1. Install the fan inline between the carbon filter and exhaust outlet.
2. Secure it with mounting brackets or hanging straps to minimise vibration.
3. Connect ducting to the fan flanges and clamp for an airtight seal.
4. Connect to a compatible EC controller such as the G.A.S Enviro V2 via a suitable EC cable for precise speed control.
5. Without a controller, the fan runs at full power (100%) in simple on/off mode.
6. Adjust airflow through the controller to hold stable temperature and humidity.
