Why Choose the Rittal SK3245.908 Blue e+ EC Fan-and-Filter Unit?
The Rittal SK3245.908 is a high-performance Blue e+ fan-and-filter unit with EC technology, designed for energy-efficient ventilation and intelligent monitoring of industrial electrical enclosures. Its electronically commutated motor, diagonal fan technology and integrated control interfaces provide powerful cooling with advanced monitoring capabilities for modern automation and control systems.
Operating from a 200–240 V AC single-phase, 50/60 Hz supply, the SK3245.908 delivers up to 1,161 m³/h unimpeded airflow with the supplied pleated filter. Rittal's diagonal fan design provides improved pressure stability for more even and consistent ventilation throughout the enclosure, making this model particularly suitable for large cabinets and installations with substantial internal heat loads.
Measuring 323 × 323 × 161 mm and finished in RAL 9005 black, the unit supports tool-free snap mounting and straightforward filter replacement. Integrated 0–10 V/PWM, speed output, floating fault contact and RS485 ModBus interfaces enable connection to automation and monitoring systems, while IoT functionality supports features including filter maintenance indication, automatic filter cleaning and emergency cooling.
Key Advantages
- High airflow of up to 1,161 m³/h with the supplied pleated filter.
- Energy-efficient EC motor technology for modern enclosure climate control.
- Integrated RS485 ModBus connectivity for monitoring and automation.

Intelligent EC Cooling for High Heat Loads
Large electrical cabinets containing variable speed drives, PLCs, power supplies, industrial computers and power electronics can generate substantial heat during continuous operation. The Rittal SK3245.908 delivers up to 1,161 m³/h of filtered airflow, while its EC motor and diagonal fan technology provide the performance required for demanding enclosure climate-control applications.
Unlike a conventional fixed-function filter fan, the SK3245.908 provides interfaces for integration with automation and monitoring systems. Its RS485 ModBus connection, 0–10 V/PWM input, speed output and fault contact allow operating status and fan behaviour to be incorporated into intelligent control strategies, helping improve maintenance planning, system availability and energy management.
Typical Applications
- Large industrial electrical control cabinets.
- Variable speed drive and motor-control enclosures.
- PLC and factory automation systems.
- Power electronics and distribution equipment.
- Connected machinery requiring fan monitoring and control.
- Industrial enclosures with high internal heat loads.
