Rittal SK 3237.800 Blue e+ EMC fan-and-filter unit, a compact 230 V single-phase enclosure cooling fan providing 20 m³/h airflow at 50 Hz and 25 m³/h at 60 Hz with integrated EMC shielding.
£163.94
The Rittal SK 3237.800 is a compact and efficient EMC fan-and-filter unit designed to provide filtered ventilation and electromagnetic shielding for electrical enclosures, control panels and industrial automation equipment. As part of the Rittal Blue e+ enclosure climate control range, it combines reliable airflow with enhanced EMC performance for sensitive industrial installations.
This wall-mounted fan-and-filter unit incorporates EMC shielding that provides a high shielding and attenuation effect and meets requirement category 2 to EN 61587-3. Diagonal fan technology improves pressure stability to support more even and consistent ventilation throughout the enclosure, while optimised detent hooks and tool-free assembly simplify installation.
Operating from a 230 V single-phase, 50/60 Hz supply, the SK 3237.800 delivers an unimpeded airflow of 20 m³/h at 50 Hz and 25 m³/h at 60 Hz. Its compact housing measures 116.5 × 116.5 × 64.5 mm, making it well suited to smaller control cabinets where dependable cooling and EMC shielding are both required.
Fan-and-filter units help regulate enclosure temperatures by moving filtered ambient air across heat-generating electrical and electronic components. Maintaining controlled airflow can reduce thermal stress, improve component reliability and support stable operation of industrial automation systems.
The SK 3237.800 is specifically designed for applications where electromagnetic compatibility is also important. Its EMC filter arrangement provides a high shielding and attenuation effect while the diagonal fan technology promotes stable airflow, making the unit suitable for control cabinets containing sensitive electronic equipment.
