The unit provides an airflow capacity ranging from 223 to 256 m³/h. It features an IP54 protection rating and measures 252mm in height and width.

Feature Summary

• Vertical slide-in ventilator design for easy installation
• Compact thermal management solution for industrial enclosures
• IP54 protection degree against dust and water

Applications

• Industrial equipment enclosure ventilation
• Control cabinet cooling
• Electrical panel thermal management

Procurement Notes

Verify the specific voltage requirement of 24V DC matches the system power supply before integration. Confirm that the required airflow capacity between 223 and 256 m³/h meets the thermal dissipation needs of the target enclosure. Ensure the physical dimensions of 252mm x 252mm fit the designated mounting opening in the enclosure panel.

Selection Notes

Select this model when a compact, low-power ventilation solution is needed for 24V DC systems. The IP54 rating makes it suitable for environments requiring protection against limited dust ingress and water jets. Consider the vertical orientation and slide-in mounting style for straightforward retrofitting or new installations in standard industrial enclosures.
