Phresh HyperFan V2 In-Line Fan with Fan Speed Controller 125mm / 150mm / 200mm / 250mm

Description Why Choose Phresh HyperFans? HyperFan is the latest technology available in mixed flow fans. HyperFans utilise aircraft taper blade technology to fully optimise the aerodynamic movement of air over the fan blades. Features and Benefits: New 9 pole digital EC brush-less motors Higher fan efficiency @7.85 cfm per Watt Higher linear air flow output than other fans Higher static pressure output than other fans Detachable, fully variable speed controller included Sturdy steel housing and Abec 7 ball bearings 0-10V controller compatible via RJ9 or RJ11 cable The importance of pressure (Pa): Static pressure is one of the most important factors in ventilation design. Simply put, static pressure refers to the airflow resistance of the components 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 this covered with one of the highest static pressures of any fan type. The coupling of taper blade technology, optimised laminar stator design and next gen 9 pole digital EC motors result in a fan that delivers unrivalled pressure, more linear air flow, quieter operation and the highest energy efficiency.
