Why Choose the Rittal SK3341.230 Rack-Mounted Fan?
The Rittal SK3341.230 is a compact 482.6 mm (19-inch) rack-mounted internal fan unit designed to provide permanent air circulation inside industrial enclosures, IT racks and control cabinets. By continuously moving air around installed equipment, it helps minimise localised heat build-up and prevents the formation of hot spots around sensitive electrical and electronic components.
Designed for direct installation in the 19-inch mounting level, the SK3341.230 incorporates three fans in a compact 1 U assembly. The unit is supplied fully wired and ready for connection, complete with a terminal strip and assembly parts, helping simplify installation in both new rack systems and retrofit applications.
With an unimpeded airflow of 480 m³/h, a 230 V AC single-phase 50/60 Hz supply and dimensions of 482.6 × 44 × 200 mm, the SK3341.230 delivers effective internal air circulation while occupying minimal rack space.

Reliable Internal Air Circulation for 19-Inch Enclosures
Electrical and electronic devices installed inside rack enclosures can generate concentrated areas of heat, particularly where natural convection is restricted. The Rittal SK3341.230 continuously circulates internal enclosure air to distribute heat more evenly, helping reduce thermal hot spots and maintain more consistent conditions around installed equipment.
Its compact rack-mounted design makes the unit particularly suitable for network hardware, communications equipment, industrial control systems, power supplies and other 19-inch electronics where additional internal airflow is required without installing a larger refrigeration-based cooling system.
Typical Applications
- 482.6 mm (19-inch) industrial racks.
- Network and telecommunications enclosures.
- Industrial control and automation cabinets.
- Server and IT equipment racks.
- Power supply and electronics enclosures.
- PLC and process control systems.
- Communications and instrumentation racks.
- Machine-building and OEM control systems.
