Why Choose the Rittal SK 3237.724 Blue e+ Fan-and-Filter Unit?
The Rittal SK 3237.724 is a compact and efficient Blue e+ fan-and-filter unit designed to provide controlled ventilation and heat dissipation for electrical enclosures, control panels and industrial automation equipment. As part of the Rittal Blue e+ enclosure climate control range, it uses diagonal fan technology to provide stable airflow and more even cooling inside the enclosure.
Designed for straightforward installation and maintenance, the SK 3237.724 features optimised detent hooks for fast mounting and a convenient opening mechanism that simplifies filter changes. The complete unit is supplied ready to install with a chopped-fibre filter mat, helping protect enclosure components against airborne contamination while maintaining effective ventilation.
With an unimpeded air throughput of 20 m³/h and a 24 V DC supply, the SK 3237.724 is particularly suitable for compact control cabinets and automation enclosures. Its wall-mounted housing measures just 116.5 × 116.5 × 64.5 mm and provides IP54 protection when used with the supplied filter.

Reliable Ventilation for Electrical Enclosures
Fan-and-filter units help control internal enclosure temperature by drawing cooler ambient air through a filter and circulating it around heat-generating electrical and electronic components. Effective airflow helps reduce thermal stress, improve component reliability and support stable operation of industrial control equipment.
The Rittal Blue e+ design uses diagonal fan technology for enhanced pressure stability and more consistent ventilation. The diagonal direction of airflow also promotes more even heat dissipation throughout the enclosure, making the SK 3237.724 well suited to compact industrial installations where reliable cooling and efficient use of space are important.
Typical Applications
- Electrical control cabinets and industrial enclosures.
- PLC and automation control panels.
- Machine control systems and OEM equipment.
- Industrial electronics and power distribution enclosures.
- Factory automation and production machinery.
- Compact cabinets requiring filtered forced-air ventilation.
