Rittal SK3326 207 Outlet Filter For Enclosure

Rittal SK3326.207 Outlet Filter is a venting accessory for enclosure cooling that mounts in the upper or lower section of Rittal enclosures to exhaust heat by convection while filtering outgoing air to protect internal components. Designed for use with the SK 3326-series filter fans, it features a mounting opening of 116.5 x 116.5 mm and a 16 mm overall depth, ensuring a compact footprint for standard enclosures. The filter uses a synthetic fiber filter element to capture dust from air exiting the enclosure, supporting longer component life and cleaner internal conditions as heat is dissipated. For energy-efficient operation of the associated filter fan, Rittal advises pairing the outlet filter with an enclosure internal thermostat, a speed control, or the digital enclosure internal temperature display and thermostat. This part integrates into Rittal’s modular climate-control ecosystem, allowing straightforward ventilation enhancements without replacing other enclosure hardware.
