Product description
SK Fan module 100-240 V, 50-60 Hz, speed-controlled, (2 fans, max. 6 fans) 280 m³/h, for VX IT, WxHxD: 550x42x340 mm, RAL 7035
The SK Fan module delivers active ventilation with speed control, enabling energy-efficient cooling that adapts to changing thermal conditions in VX IT enclosures. This directly translates to improved reliability of sensitive electronics and longer service intervals in industrial automation. Its simple C13 IEC 320 connection minimizes commissioning time and reduces wiring errors during installation, which lowers total cost of ownership. The design supports expansion from two to up to six fans, providing scalable airflow of 280 m³/h at the operating point, with a documented performance at 25 Pa that helps engineers predict real-world cooling in demanding cabinets. Dimensions of 550 x 42 x 340 mm and IP 20 protection ensure rugged compatibility with VX IT and TS IT enclosures, while a 10 A pre-fuse protects downstream components, aligning with standard plant electrical practices. The unit operates from 5 °C to 55 °C and consumes 42.5 W, balancing thermal effectiveness with energy efficiency. Weighting at 3.8 kg and a complete package including mounting parts and installation guide support quick deployment in existing systems. Overall, the SK Fan module harmonizes with Rittal enclosure ecosystems, offering reliable, compliant, and cost-conscious cooling for industrial cabinets and data center cabinets alike.
