EF250-115R5

Overview

The EF250-115R5 is a rack-mounted filter fan manufactured by nVent HOFFMAN. It features external dimensions of 252mm height by 252mm width, with a required cut-out dimension of 223mm by 223mm. The unit operates on a supply voltage of 115VAC and provides an ingress protection rating of IP54. The internal depth extending into the enclosure is 97mm.

Feature Summary

• Provides active air filtration for thermal management in rack enclosures
• Constructed to meet IP54 ingress protection standards
• Designed for direct mounting into standard panel cut-outs

Applications

• Industrial control cabinet ventilation
• Telecommunications equipment cooling
• Rack-mounted electronic system thermal regulation

Procurement Notes

Verify that the installation site accommodates the specific 223mm x 223mm cut-out requirement and 97mm internal depth. Confirm compatibility with the local 115VAC power infrastructure before procurement. Ensure the selected enclosure material supports the mounting hardware specified in the official mechanical drawings.

Selection Notes

Select this model when precise dimensional constraints require a 252mm square form factor. The IP54 rating makes it suitable for environments requiring protection against dust and water splashes. Verify that the 115VAC input matches the available control power source within the target rack assembly.

Part Context

This component belongs to the Hoffman Enclosures filter fan series designed for rack applications. It serves as a thermal management solution for protecting sensitive electronics from overheating while maintaining environmental sealing integrity within industrial or commercial rack structures.

Replacement Considerations

Cross-reference with other models in the EF250 series for alternative voltage options. Verify that substitute units maintain identical 223mm x 223mm cut-out dimensions and 97mm depth to ensure physical compatibility without enclosure modification.
