OPTIMISED FOR STATIC PRESSURE: During the development of the new BioniX P120, special emphasis was placed on a focused airstream and thus a high static pressure PWM SHARING TECHNLOGY (PST): PST ensures that all your fans listen to a single control signal, stop at low load, turn whenever necessary EFFICIENT ENGINE MODERNISATION: Thanks to sinusoidal magnetation, the new engine generates only 5% of the vibrations due to the switching of an ordinary DC motor 200 TO 2100 RPM REGULATED VIA PWM PST: With a wide range of regulation and the PWM Sharing Technology (PST), the BioniX P120 fan speed can be controlled synchronously with all your other fans together TECHNICAL DATA: Fan speed: 200–2100 rpm, Airflow: 67.56 cfm | 114.9 m³/h, Noise Level: 0.45 Sone, Static Pressure: 2.75 mmH?O, Pin: 4-pin
