Rack accessory Rittal 3244.740 — plastic housing, airflow 910 m³/h, white

Rittal 3244.740 is a rack accessory featuring a white plastic housing designed to manage and direct airflow in server and network cabinets. The unit provides an airflow capacity of 910 m³/h and is intended for integration into enclosure systems to support ventilation and cooling. Supplied as a single unit with a compact form factor, this accessory aligns with applications requiring reliable air movement while maintaining a neutral appearance in IT environments.

Advantages

The plastic housing offers lightweight installation and corrosion-resistant properties compared with metal alternatives. With an airflow rating of 910 m³/h, the unit delivers substantial air transfer suitable for medium-duty cooling needs in racks and enclosures. The white finish supports aesthetic integration into light-coloured cabinets and room environments while the tool-free installation design common to similar Rittal fan-and-filter units simplifies mounting and maintenance.

Suitable for

• Ventilation and cooling of server racks and network cabinets
• Replacement or upgrade of existing air-moving components in enclosures
• IT rooms and telecommunication closets where controlled airflow is required
• Applications requiring a lightweight, corrosion-resistant housing

How to use

Install the accessory into the designated cut-out or mounting location in the rack or cabinet wall according to the enclosure manufacturer’s instructions. Ensure the unit is oriented to match the intended airflow direction for intake or exhaust. Connect any required electrical supply following local regulations and safety standards, and verify seals and panel fit to maintain enclosure integrity. After installation, run the system and confirm expected airflow and temperature profiles within the rack to validate cooling performance.

Usage recommendations

Position the unit to balance intake and exhaust flows and avoid directing hot exhaust air toward intake openings. Periodically inspect and clean surrounding filters or airflow passages to sustain the rated 910 m³/h performance. For systems with higher heat loads, consider using multiple units or combining with additional cooling measures to achieve target temperatures.
