The P12 Pro Reverse is specially designed for air intake from the rear. It is particularly suitable when conventional fans would detract from the visual appearance. The funnel-shaped air inlet and the drop-shaped struts direct the air flow with reduced flow losses. This reduces air resistance and minimises turbulence and aerodynamic noise. Reduces motor noise, equalises load fluctuations and protects against inrush current peaks and polarity reversal. An automated measuring and balancing process ensures optimum running smoothness thanks to precisely injected equalising compound. Enables higher static pressure and maximum airflow efficiency. Thanks to the additional PWM socket, several fans can be connected in series and controlled together via just one connection. Hydrodynamic sleeve bearing and extended shaft ensure quiet running thanks to better pressure distribution and fewer vibrations.
