Filter for Rittal rack accessory 3237.067 — anthracite, pack of 5

Rittal 3237.067 replacement filter elements are spare filter mats designed for use with compatible Rittal rack fan and filter units. Supplied in anthracite and sold as a pack of five, these filters are intended to maintain clean airflow through roof-mounted fans, fan-and-filter assemblies or thermoelectric coolers used in server racks and electrical enclosures. The lightweight filter mats help protect sensitive electronics from dust, dirt and coarse particles while allowing adequate ventilation.

Advantages

These replacement filter mats provide a simple means of maintaining ventilation performance and prolonging component life by reducing dust ingress. Supplied as a five-piece pack, they allow for scheduled replacement intervals without interrupting rack operation. The anthracite color is neutral and suitable for professional rack environments. The design focuses on preserving airflow while trapping larger particulates that could accumulate on heat sinks, fan blades, and enclosure surfaces.

Suitable for

• Replacement filter mats for compatible Rittal roof-mounted fans and fan-and-filter units
• Enclosures and server racks where protection from dust and coarse particles is required
• Maintenance stock for IT rooms, network cabinets and industrial control cabinets

When it may not be suitable

These filter mats are intended as coarse or general-purpose replacement elements and may not provide the level of fine particulate or HEPA filtration needed in cleanroom or medical environments. They are designed to work with compatible Rittal fan/filter assemblies; they will not function as standalone sealed filters or replace filters specified for other manufacturers without verifying compatibility.

Key specifications

• Pack quantity: five filter elements
• Color: anthracite
• Intended application: roof-mounted fans, fan-and-filter units, thermoelectric coolers in racks and enclosures
• Function: coarse particulate filtration to protect electronics and maintain airflow

How to use

Replace the filter mats according to the maintenance schedule of the rack or enclosure. Power down or follow the manufacturer’s safe-access procedures for the fan or fan-and-filter unit, remove the old filter mat from its frame or housing, and insert the new filter ensuring correct orientation and a secure fit. Verify that the fan housing is closed and sealed as designed before restoring normal operation. Inspect filters periodically for visible contamination and replace sooner if airflow is reduced or heavy dust accumulation is observed.

What to consider before purchase

• Confirm compatibility with your specific Rittal fan or fan-and-filter unit model
• Determine the required replacement interval based on site dust levels and operating hours
• Assess whether a finer filtration grade is needed for your environment

Usage recommendations

Store spare filter mats in a dry, dust-free location until installation. Establish a replacement routine based on visual inspection and airflow measurements; in dusty environments inspect more frequently. When installing, ensure a proper fit to avoid bypassing unfiltered air.
