Why Choose the Rittal SK 3239.700 Blue e+ Fan-and-Filter Unit?
The Rittal SK 3239.700 is a high-performance Blue e+ fan-and-filter unit designed to provide reliable filtered forced-air cooling for electrical enclosures, control panels and industrial automation systems. As part of the advanced Rittal Blue e+ enclosure climate control range, it uses diagonal fan technology to deliver greater pressure stability and more consistent airflow for even cooling throughout the enclosure.
The SK 3239.700 is supplied as a complete, ready-to-install unit with a high-performance pleated filter. Optimised snap-in hooks enable fast, tool-free mounting into the enclosure panel, while the opening mechanism integrated into the louvred grille simplifies routine filter replacement. The pleated filter provides high airflow while helping protect internal electrical and electronic components against dust and airborne contamination.
Operating from a 230 V single-phase, 50/60 Hz supply, the SK 3239.700 delivers an unimpeded airflow of 110 m³/h at 50 Hz and 125 m³/h at 60 Hz with its standard pleated filter. Its 204 × 204 × 105 mm housing, IP54 protection and NEMA Type 12 rating make it an effective cooling solution for industrial control cabinets and machinery enclosures.

Reliable Filtered Cooling for Industrial Enclosures
Fan-and-filter units provide forced-air enclosure cooling by drawing cooler ambient air through a filter and circulating it across heat-generating electrical and electronic components. This continuous airflow helps reduce internal enclosure temperatures, limit thermal stress and support reliable operation of PLCs, drives, power supplies and other industrial control equipment.
The Rittal Blue e+ design uses diagonal fan technology for increased pressure stability and more consistent ventilation throughout the cabinet. Combined with the high-performance pleated filter, the SK 3239.700 provides efficient airflow while helping reduce the ingress of dust and airborne particles, making it well suited to demanding industrial control and automation applications.
Typical Applications
- Electrical control cabinets and industrial enclosures.
- PLC and automation control panels.
- Machine control systems and OEM equipment.
- Variable speed drive and motor control enclosures.
- Industrial electronics and power distribution cabinets.
- Factory automation and production machinery.
