SK3325.107 Rittal 230V 255mm AC Fan-and-filter Unit

Description

The Rittal SK3325.107 is a high-performance 230VAC Fan-and-filter unit with external dimensions of 255 x 255 x 105 mm, featuring an integrated ebmpapst shaded pole motor specifically engineered for mission-critical cooling in Industrial Frequency Converters and TopTherm enclosure systems. Driven by a precision-balanced motor with maintenance-free ball bearings and moisture protection, this 1.95 kg unit operates at 230 VAC / 50/60 Hz delivering a Max. Power Consumption of 41.0 / 38.0 W and a Max. Current Draw of 0.28 / 0.24 A. This High-performance unit achieves an unimpeded Air Flow of 230.0 / 265.0 m³/h (135.4 / 156.0 CFM / 3.83 / 4.42 m³/min) and a Max. Static Pressure of 16.32 / 19.37 mmH₂O (160.0 / 190.0 Pa / 0.64 / 0.76 inAq). Featuring a tool-free mounting system and a robust RAL 7035 ABS plastic housing, this IP54-rated unit is optimized for environments requiring high reliability and filtered laminar airflow in industrial VFD systems at the end.
