The advanced stealth silencer with integrated Hyperfan V2. • 50% cheaper to run than AC equivalents • ‘Soft-start’ circuitry for less wear and tear • Most powerful EC fan of its size, class and price Super quiet in operation, the Silenced Hyperfan V2 uses the Hyperfan technology wrapped up in an acoustic foam and robust silencing canister. The Silenced Hyperfan V2 has been designed and constructed to eliminate sound whilst moving large volumes of air under the usual pressures of a grow room environment. Supplied with a detachable speed controller, adjustable from 0%-100%, allowing growers to have improved control of air flow levels. The importance of pressure (Pa) Static pressure refers to the air flow resistance of filters and duct work in a ventilation system. The air pressure must be greater than the resistance to the flow. The higher the fans static pressure rating (Pa) the greater its ability to remove either hot or stale air from the environment. Hyperfan™ has one of the highest static pressures of any fan type whilst delivering a more linear air flow, quieter operation and the highest energy efficiency. • Silencing Canister • Dual sleeve collar for universal fitting • Easy-fit hanging brackets • Acoustic foam
