## Long description

The Rittal SK 3243.900 fan kit is a built-in AC fan assembly designed for ventilation and cooling of electrical enclosures and control cabinets. The unit contains a single fan with a nominal airflow of 540 m³/h and is housed in a grey plastic frame. It is supplied as one complete kit intended to maintain airflow, expel heat and help stabilize internal temperatures in industrial and IT cabinets.
Advantages
The kit provides a compact, ready-to-install solution for enclosure ventilation without the need to source separate fan and housing components. With an airflow rating of 540 m³/h the unit can move significant air volume for continuous cooling of electrical components. The plastic grey housing offers corrosion resistance and reduced weight compared with metal housings, facilitating easier mounting and handling.
Suitable for (tasks / use cases)
 Ventilation of electrical distribution cabinets and control panels
 Cooling of small to medium-sized industrial enclosures
 Maintaining air circulation in IT racks and networking cabinets
 Replacing a single damaged or underperforming enclosure fan
When it may not be suitable
This fan kit uses an AC fan with a fixed nominal airflow; it may not be suitable where variable-speed control or EC motor efficiency is required for energy-optimised systems. It is designed as a single-fan solution and therefore may not provide sufficient cooling capacity for very large enclosures or installations that require redundancy. If dust filtration, integrated monitoring or higher airflows are mandatory, consider a fan-and-filter unit or a multi-fan solution instead.
Key specifications
 Airflow: 540 m³/h (nominal)
 Quantity: 1 fan
 Housing material: plastic
 Housing colour: grey
 Mounting type: built-in (enclosure panel installation)
How to use
Install the fan kit into the prepared cutout in the enclosure panel following the enclosure manufacturer’s mounting guidelines. Ensure correct orientation for intake and exhaust airflow and make secure electrical connections according to local electrical standards and the fan’s wiring diagram. After installation, verify airflow direction and check for obstructions. Routine inspection and cleaning of the housing and fan impeller will help maintain rated airflow and operational reliability.
What to consider before purchase
 Confirm the required airflow for your enclosure to ensure 540 m³/h is sufficient.
 Verify cutout dimensions and mounting compatibility with your enclosure panel.
 Check electrical supply compatibility with the fan’s AC power requirements.
 Decide whether integrated filtration, monitoring or EC motor technology is needed for your application.
Usage recommendations
For stable performance, position the fan to create a clear exhaust or intake path, avoid mounting near heat sources without appropriate separation, and schedule periodic cleaning to prevent dust build-up that can reduce airflow.
