£98.80
The Rittal SK 3238.400 is a compact Blue e+ EMC outlet filter designed for use with Rittal SK 3238.8xx fan-and-filter units to provide effective ventilation and electromagnetic compatibility for electrical enclosures, control panels and industrial automation equipment. As part of the Rittal Blue e+ enclosure climate control range, it provides a controlled outlet for heated air while helping protect temperature-sensitive and EMC-sensitive components.
Designed for straightforward installation and maintenance, the SK 3238.400 features optimised detent hooks for faster enclosure mounting and supports tool-free assembly. A convenient opening mechanism on the louvred grille simplifies filter changes, while the supplied EMC filter mat provides the filtration and shielding required for compatible EMC enclosure ventilation systems.
The SK 3238.400 has external dimensions of 148.5 × 148.5 × 34.2 mm and requires a 124 × 124 mm mounting cut-out. Its wall-mounted construction and RAL 7035 light-grey finish make it well suited to industrial control cabinets using Rittal SK 3238.8xx EMC fan-and-filter units.
Outlet filters form an important part of forced-air enclosure cooling systems by providing a controlled path for heated air to leave the cabinet. When paired with a corresponding fan-and-filter unit, the Rittal SK 3238.400 supports continuous airflow through the enclosure, helping dissipate heat generated by electrical and electronic components.
The EMC version is designed for installations where electromagnetic compatibility must also be considered. Its supplied EMC filter mat allows the outlet to form part of a compatible EMC ventilation system while retaining the practical installation and maintenance benefits of the Blue e+ range, making it particularly suitable for control cabinets containing sensitive electronic equipment.
