Rittal 3245.908 rack accessory — built-in fan 1x, airflow 931 m³/h, plastic housing, black

Rittal 3245.908 is a rack accessory featuring a single built-in fan designed for forced ventilation and heat dissipation in server cabinets, control enclosures and industrial racks. The unit has a plastic housing in black and provides an airflow of 931 m³/h. Supplied as one piece per pack, it is intended to help maintain internal temperatures and support reliable operation of installed components.

Advantages

The built-in fan delivers a measured airflow of 931 m³/h, enabling effective air exchange in compact racks and enclosures. Its plastic housing and black finish make it lightweight and visually compatible with typical server and control cabinet interiors. Supplied as a single unit per package, the accessory can be integrated where an individual fan module is required. The product is compatible with rack and cabinet ventilation strategies that rely on forced-air circulation to remove heat from sensitive electronics.

Suitable for

• Server cabinets and small data racks requiring supplemental ventilation
• Control enclosures and automation cabinets with moderate heat loads
• Industrial racks where a single fan module is needed for spot cooling or airflow management

When it may not be suitable

This fan unit is designed as a single built-in module with a specified airflow of 931 m³/h and a plastic housing; it may not be suitable for applications requiring higher redundancy, redundant fans, or metal housings for specific grounding or robustness requirements. It is not a complete cooling system and should be integrated into a broader thermal management plan rather than relied on as the sole method of cooling for high-density installations.

Key specifications

• Airflow: 931 m³/h
• Number of built-in fans: 1
• Housing material: plastic
• Colour: black
• Package quantity: 1 piece

How to use

Install the fan module into the designated rack or enclosure opening following the cabinet manufacturer’s mounting instructions and safety guidelines. Connect the electrical supply as specified by the rack wiring diagram and ensure correct airflow direction for intake or exhaust as required by the cabinet layout. After installation, verify electrical connections, secure the module mechanically, and perform a functional check to confirm the fan operates and provides the expected airflow. Monitor temperatures in the rack after commissioning to verify the desired cooling effect.

What to consider before purchase

• Confirm the fan’s airflow (931 m³/h) meets the cooling requirements of the intended rack or enclosure.
• Verify mechanical compatibility with the cabinet’s fan cutout and mounting provisions.
• Check electrical requirements and connectors to ensure compatibility with the rack’s power supply and control circuitry.

Usage recommendations

Use this fan as part of a coordinated ventilation strategy: place it where it complements existing intake/exhaust paths, maintain regular cleaning of inlet and outlet areas, and include periodic operational checks to ensure consistent airflow and temperature control within the enclosure.
