Description
The Rittal SK3139.100 is a high-performance TopTherm roof-mounted fan unit with a nominal voltage of 230 VAC and external dimensions of 400 x 133 x 400 mm, specifically engineered for high-protection air extraction in electrical enclosures and server racks. Driven by a high-efficiency radial capacitor motor with a power consumption of 51 W at 50 Hz and 62 W at 60 Hz, this unit features a heavy-duty ball bearing system designed for long-term mechanical stability with a service life of up to 69,000 hours. Its advanced aerodynamic design delivers an unimpeded air throughput of 500 m³/h, which remains a robust 474 m³/h even when equipped with the integrated pleated filter for enhanced filtration. Constructed with a durable RAL 7035 light grey housing and featuring an innovative clamping attachment for flexible installation from inside or outside, this 5.16 kg unit provides a dependable and energy-efficient cooling solution with IP54 protection and NEMA 12 rating for industrial power distribution, telecommunications hubs, and automated control infrastructure at the end.
