The Revolution Silenced Stratos 200 AC is designed and developed by Systemair to combine their classic Revolution fans with silence. The Revolution Silenced Stratos 200 AC takes the same German engineered and manufactured Revolution fan, wraps it in an acoustic foam specially designed to absorb noise without restricting air flow, and finally encases it in a sealed steel housing to prevent any odour leaks from your grow room environment.
