SK3244.708 Rittal SK Blue E+ Fan-And-Filter Unit, 867/910 M³/H, 230 V, 1~, 50 Hz/60 Hz, WxHxD 323 X 323 X 156 mm, Ral 9005

Why Choose the Rittal SK3244.708 Blue e+ Fan-and-Filter Unit?

The Rittal SK3244.708 is a high-performance Blue e+ fan-and-filter unit designed for powerful filtered ventilation of industrial electrical enclosures and control cabinets. With its high airflow capacity, it provides an effective way to remove heat generated by drives, power electronics, PLCs and other electrical equipment while filtering incoming ambient air.

Operating from a 230 V AC single-phase, 50/60 Hz supply, the SK3244.708 delivers an airflow of 867 m³/h at 50 Hz and 910 m³/h at 60 Hz. This substantial ventilation performance makes it particularly suitable for larger enclosures and densely populated cabinets with demanding thermal loads.

Measuring 323 × 323 × 156 mm and finished in RAL 9005 black, the SK3244.708 combines high-volume airflow with the installation and maintenance benefits of the Rittal Blue e+ range. Its filtered forced-air design helps maintain suitable enclosure temperatures while reducing the amount of dust and airborne contamination reaching sensitive components.

Key Advantages

• High-capacity Blue e+ filtered ventilation for demanding industrial enclosures.
• Provides 867 m³/h airflow at 50 Hz and 910 m³/h at 60 Hz.

Powerful Cooling for High Heat Loads

Large electrical cabinets containing variable speed drives, power supplies, contactors, PLC systems and power electronics can produce considerable heat during continuous operation. The Rittal SK3244.708 uses high-volume forced-air ventilation to introduce filtered ambient air into the enclosure, helping transfer excess heat away from components and maintain more stable internal temperatures.

With airflow reaching 910 m³/h, the SK3244.708 is particularly well suited to larger cabinets and applications where lower-capacity filter fans may not provide sufficient ventilation. When used with a correctly sized outlet filter, it establishes controlled airflow through the enclosure for efficient and economical thermal management wherever ambient conditions permit direct air cooling.

Typical Applications

• Large industrial electrical control cabinets.
• Variable speed drive and motor-control enclosures.
• PLC and factory automation systems.
• Power distribution and switching cabinets.
• Production and processing machinery.
• Industrial enclosures with high internal heat loads.
