Operating range Nominal voltage Voltage range Current Power Speed Air flow Typ. Working point Current (Appr. 50% Qmax) Power Speed Air flow Pressure Static pressure Free blowing Current Power Speed Pressure Airflow [l/min]

Maximum speed Max. allowed temperature on heat sink surface: Blower limits Exceeding the blower limits during continuous operation may cause permanent damage! Handle only in currentless condition! Information Heat sink temperature increase, freeblowing Heat sink temperature increase, static pressure Power supply requirements Ripple voltage < 5% 3000 mA (nominal voltage) Acoustic emission level at nominal voltage Balancing class 10’000h at nominal voltage Outlet orifice: 6.52 mm Ambient temperature: 25°C Cycle: 24h on Air quality: free of dust, fumes and unnatural concentrations of gases....
