Phresh Hyperfan Stealth V2
The Stealth Hyperfan runs with EC technology - Quieter and up to 50% more efficient than their traditional AC counterparts, they pay for themselves in engery saving costs.
They shift a greater volume of air for every watt consumed and give greater air flows under the usual pressures of a grow room enviroment like carbon filters. The Stealth Hyperfan also comes with benefit of producing less noise than AC fans or non-silenced EC fans. The acoustic foam and silencing cannister dampens the noise from your air flow without restricting it.
