Why Choose the Rittal SK 3243.500 TopTherm Fan-and-Filter Unit?
The Rittal SK 3243.500 is an energy-efficient TopTherm fan-and-filter unit with EC technology designed for high-capacity forced-air cooling of electrical enclosures, control cabinets and industrial automation systems. Its diagonal fan with EC motor provides pressure-stable airflow while reducing energy consumption compared with conventional fan technology, making it well suited to continuously ventilated industrial installations.
The SK 3243.500 incorporates a 0–10 V / PWM control interface with tacho signal output, allowing the fan to be controlled and monitored as part of an enclosure climate management system. Fan speed and operating function can therefore be supervised, helping optimise cooling performance and energy consumption according to the actual thermal requirements of the enclosure.
Operating from a 200–240 V single-phase, 50/60 Hz supply, the current SK 3243.500 provides an unimpeded airflow of 540 m³/h at 50 Hz and 60 Hz with the supplied chopped-fibre filter, closely corresponding to the nominal 550 m³/h rating associated with earlier specifications. An optional pleated filter increases unimpeded airflow to 625 m³/h at 50 Hz and 716 m³/h at 60 Hz, while standard enclosure protection is IP54.

Energy-Efficient EC Cooling for Industrial Enclosures
Fan-and-filter units provide forced-air enclosure cooling by drawing cooler ambient air through filter media and circulating it across heat-generating electrical and electronic components. The resulting airflow helps control internal temperatures, reduce thermal stress and support reliable operation of PLCs, variable speed drives, power supplies and other industrial control equipment.
The Rittal SK 3243.500 enhances this cooling principle with an EC motor and integrated control interface. The fan can be regulated through a 0–10 V or PWM input and monitored using its tacho signal output, allowing airflow to be matched more closely to actual cooling demand. This makes the unit particularly suitable for installations where energy efficiency, fan monitoring and high airflow are important.
Typical Applications
- Large electrical control cabinets and industrial enclosures.
- PLC and factory automation control panels.
- Variable speed drive and motor control enclosures.
- Machine control systems and OEM production equipment.
- Industrial electronics and power distribution cabinets.
- Applications requiring controllable, monitored and energy-efficient enclosure ventilation.
