Computer case Fan 14 cm 2000 RPM 31.5 dB 4.18 mmH2O Self-Stabilising Oil-pressure Bearing (SSO) Pulse-width modulation (PWM) support 140 x 140 x 25 mm Black, Brown 1 pc(s) Conceived for industrial heavy duty applications that require enhanced cooling performance and advanced ingress protection, the NF-A14 industrialPPC (Protected Performance Cooling) is a ruggedised high-speed version of the award-winning retail model. Thanks to the outstanding aerodynamic efficiency of the NF-A14 design and the use of a novel three-phase motor, the industrialPPC version provides superior airflow and pressure capacity while keeping noise levels and power consumption moderate as against comparable high-speed fans. While its fibre-glass reinforced polyamide construction and certified water and dust protection make the NF-A14 industrialPPC suitable for operation in challenging environments, the renowned SSO2 bearing technology guarantees an MTTF of over 150.000hrs.
