Conceived for industrial heavy duty applications that require enhanced cooling performance and advanced ingress protection, the NF-A14 industrialPPC (Protected Performance Cooling) is a ruggedized 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 fiber-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 MTBF of over 150.000hrs. Topped off with Noctuid's trusted reliability and 6 years manufacturer's warranty, the NF-A14 industrialPPC is an ideal choice for highly demanding applications that require superior flow rates and ultimate dependability. NF-A14 industrialPPC-2000 provides a significant performance boost over the 1500rpm retail version. Combined w/ the industrialPPC series' robust polyamide construction & adv. protection features makes the fan ideal for challenging industrial applications. Noctuid's industrialPPC fans feature a three-phase design with 6 slots, which provides smoother transitions b model : NF-A14 iPPC-2000 PWM tag : Case Fans
