Description
Revolution 250 Stratos AC Silenced 2038 m³/hr is a high-capacity, acoustically optimised AC inline fan from Revolution Fans, delivering 2038 cubic metres per hour of extraction airflow through a 250mm housing with the low noise signature that Revolution’s silenced technology is renowned for in professional UK grow rooms. We have been recommending Revolution silenced fans to UK growers since 2017 as the benchmark for high-volume, low-noise extraction — and the 250 Stratos AC delivers commercial-scale airflow capacity for large grow rooms while maintaining the quiet operation that makes it suitable even in noise-sensitive installations.
How Revolution’s Silenced Housing Achieves Low Noise at High Flow
Conventional inline fans at 2038 m³/hr flow rates generate significant noise from both motor operation and air turbulence through the fan housing and impeller. Revolution’s Stratos silenced design addresses both noise sources through an integrated acoustic chamber approach: the impeller and motor are mounted within an inner housing lined with acoustic damping material, which is then decoupled from the outer stainless steel casing by vibration-isolating gaskets and mounts. This double-isolation approach attenuates both the airborne noise generated by the fan’s operation and the structure-borne vibration that would otherwise be transmitted into the ductwork and building fabric. The result is a fan that delivers commercial-scale extraction capacity at a noise level genuinely suitable for noise-sensitive environments. The AC motor specification of the Stratos model makes it compatible with standard single-speed or variable triac controllers where EC technology is not required, providing a cost-effective option for large-scale extraction at fixed speeds.
How to Install the Revolution 250 Stratos AC Silenced
Mount the fan in your 250mm duct run using METU clamps for airtight connections. Support the fan independently with mounting brackets — at this size and weight, unsupported duct connections will be stressed over time. Connect to a compatible AC speed controller if variable speed is required. Combine with Phonic Trap 254mm acoustic ducting on both inlet and outlet sides for maximum noise reduction. Connect to a Can-Lite or Carbo Air 250mm carbon filter for complete odour control. Inspect and clean the impeller every 3–6 months to maintain peak performance.
Pair the Revolution 250 Stratos with a 250mm carbon filter, Phonic Trap acoustic ducting, and a compatible speed controller for a complete, high-capacity, and professionally quiet extraction system. Browse our full Revolution fan range for the complete ventilation solution.
