Why Choose the Rittal TopTherm SK3238.500 Fan-and-Filter Unit?
The Rittal TopTherm SK3238.500 is an energy-efficient wall-mounted fan-and-filter unit with EC technology, designed to provide filtered forced-air ventilation for industrial electrical and electronic enclosures. Its diagonal EC fan technology combines efficient operation with a compact installation footprint, making it well suited to smaller control cabinets and automation enclosures.
The SK3238.500 delivers 52 m³/h unimpeded airflow with the standard chopped-fibre filter. An optional pleated filter can increase unimpeded airflow to 63 m³/h at 50 Hz and 70 m³/h at 60 Hz. When paired with one SK3238.200 outlet filter and standard chopped-fibre filtration, the system provides approximately 36 m³/h airflow, increasing to 46 m³/h when two outlet filters are used.
Designed for a 200–240 V AC single-phase, 50/60 Hz supply, the unit consumes just 5.8 W and uses a diagonal EC motor. Its 148.5 × 148.5 mm front dimensions, 16 mm build depth and 124 × 124 mm mounting cut-out support compact installation, while IP54 protection helps protect enclosure equipment in industrial environments.

Energy-Efficient Ventilation for Industrial Enclosures
The Rittal TopTherm SK3238.500 provides forced-air cooling where the ambient temperature is sufficiently lower than the required internal enclosure temperature. Its EC-driven diagonal fan draws filtered ambient air through the cabinet, removing heat generated by PLCs, power supplies, relays and other electrical components without the energy requirements of compressor-based cooling.
The standard chopped-fibre filter provides effective general-purpose enclosure ventilation, while an optional pleated filter can increase available airflow. Used with appropriately sized outlet filters, the SK3238.500 creates a controlled airflow path through the enclosure while helping limit the ingress of dust and airborne contamination.
Typical Applications
- Industrial electrical control cabinets.
- PLC and automation enclosures.
- Machine control panels.
- Power supply and relay enclosures.
- Motor control and distribution cabinets.
- Manufacturing and process automation equipment.
- Enclosures requiring energy-efficient filtered forced-air ventilation.
