Fan kit Rittal SK 3238.708 — built-in AC fan, airflow 64 m³/h, plastic housing, black

Rittal SK 3238.708 is a compact built-in AC fan kit designed to provide forced ventilation for cabinets and electrical enclosures. The unit combines a plastic housing in black with an AC-driven impeller that delivers an airflow of 64 m³/h, making it suitable for targeted removal of heat and maintenance of stable internal temperatures in confined spaces. The kit is supplied as a single complete fan unit for tool-free surface mounting and is intended for standard industrial and commercial enclosure ventilation tasks.

Advantages

The fan kit offers a consistent airflow of 64 m³/h with AC power operation, ensuring dependable ventilation without complex installation steps. Its plastic housing reduces weight and resists corrosion, while the black finish allows unobtrusive integration into most enclosures. The supplied unit is ready for immediate mounting and includes a design compatible with common panel cutouts, simplifying upgrades or replacements in existing cabinet systems.

Suitable for (tasks / use cases)

• Ventilation of small to medium electrical cabinets and control panels
• Cooling of electronic modules and power supplies inside enclosures
• Replacement of existing built-in fans with similar airflow and mounting dimensions
• Applications requiring basic protection against dust and splashes in line with common enclosure standards

When it may not be suitable

This fan kit is intended for localized enclosure ventilation and is not designed for large-volume room ventilation or ducted HVAC systems. For applications requiring significantly higher airflows, active temperature control, or integration into complex ventilation networks, a larger or differently specified fan system should be selected.

Key specifications

• Airflow: 64 m³/h
• Drive type: AC motor
• Housing material: plastic
• Color: black
• Supply configuration: single complete fan unit for tool-free mounting
• Protection class: standard models compatible with IP54-level enclosure protection

How to use

Prepare the panel or cabinet cutout that matches the unit dimensions, then position the fan kit in the opening and secure it using the tool-free mounting features supplied with the unit. Connect the AC supply following the enclosure’s wiring practices and applicable safety standards, ensuring power is isolated during installation. After installation, verify airflow direction and secure any internal wiring to prevent contact with the impeller. Periodically inspect the housing and fan for dust buildup and clean as needed to maintain airflow performance.

What to consider before purchase

• Required airflow for the enclosure to ensure 64 m³/h meets cooling needs
• Compatibility of the fan cutout and mounting method with your cabinet or panel
• Electrical supply type and voltage compatibility for AC operation
• Environmental protection requirements (e.g., dust or splash resistance) and whether IP54-level protection is sufficient

Usage recommendations

Install the fan with the correct airflow orientation and allow for unobstructed intake and exhaust paths. Schedule regular visual inspections and clean any accumulated dust from the housing and impeller to preserve airflow and reduce noise. For enclosures with higher thermal loads, evaluate adding additional ventilation points or higher-capacity fans.
