Rittal SK3240.724 Blue e+ fan-and-filter unit providing up to 218 m³/h filtered airflow from a 24 V DC supply in a 255 x 255 x 129 mm RAL 7035 housing for industrial enclosure cooling.
£241.67
The Rittal SK3240.724 is a powerful Blue e+ fan-and-filter unit designed to provide reliable filtered ventilation for electrical enclosures, control cabinets and industrial automation equipment. Operating from a 24 V DC supply, it combines efficient forced-air cooling with a compact enclosure-mounted format suitable for modern machinery and control systems.
With a maximum airflow of 218 m³/h, the SK3240.724 is designed to remove heat generated by electrical and electronic components while filtering incoming ambient air. Rittal Blue e+ fan-and-filter technology provides effective airflow and pressure stability, helping maintain suitable operating temperatures inside industrial enclosures.
Measuring 255 × 255 × 129 mm and finished in RAL 7035 light grey, the SK3240.724 integrates neatly with industrial enclosure systems. Its accessible filter arrangement and installation-friendly design simplify routine maintenance while providing dependable ventilation for PLCs, drives, power supplies and other heat-generating equipment.
Heat generated by PLCs, power supplies, drives and other electrical components can raise internal enclosure temperatures and reduce equipment reliability. The Rittal SK3240.724 provides forced-air ventilation by drawing cooler ambient air through its filter and circulating it through the enclosure, helping remove excess heat while reducing the entry of airborne contamination.
Its 24 V DC supply makes the unit particularly suitable for machinery and automation systems where low-voltage DC control power is already available. When used with a correctly sized outlet filter, the Blue e+ fan-and-filter unit establishes controlled airflow through the cabinet for efficient and economical enclosure climate control.
