The RITTAL 3237200 is a standard outlet filter designed for convection-based ventilation in electrical enclosures. It mounts in the upper or lower sections of an enclosure to allow warm air to exit while blocking dust and particulates from entering through the exhaust opening. The housing is molded from ABS plastic in RAL 7035 light gray and measures 4.8 x 4.8 x 1.6 inches. An IP54 protection rating confirms the assembly resists dust ingress and splash from any direction. Each unit ships with a fleece filter mat already included. Industrial electricians and panel builders install this component during enclosure climate control builds or as a maintenance replacement.
This outlet filter is sized for square fan openings and is rated for use with 15 CFM fans in the Rittal 3237 Series. It is well suited to industrial control panels, distribution enclosures, and automation cabinets where convection airflow is used to manage internal temperatures without an active fan-and-filter unit. The filter mat captures airborne dust and debris at the exhaust point, extending the service life of internal components. It is appropriate for both new installations and retrofit applications in light industrial and commercial environments.
Designed for use with the Rittal 3237 Series and 15 CFM fan configurations. Fits square fan openings in Rittal electrical enclosures that use convection-based climate control.
Installation is typically performed by a licensed electrician or panel builder. De-energize the enclosure and follow lockout/tagout procedures before opening the panel or servicing any ventilation components. The filter snaps or mounts into the designated cutout in the enclosure wall - verify cutout dimensions against the filter body before installation. Replace the fleece filter mat on a regular maintenance schedule to maintain the IP54 rating and prevent restriction of airflow.
