DFN02

Overview

The DFN02 is a ventilation fan top manufactured by nVent Hoffman, designed for IEC enclosure standards. It features a body width of 4.69 inches and supports a maximum AC voltage rating of 240 volts. The unit operates within an input voltage range of 220 to 240 volts AC. This component serves as an enclosure accessory intended for mounting on the top surface of compatible enclosures to facilitate cooling through high airflow.

Feature Summary

• Designed for top-surface mounting on enclosures
• Provides high airflow ventilation for cooling
• Compatible with IEC enclosure standards

Applications

• Cooling electrical enclosures via top-mounted installation
• Industrial control panel ventilation
• Enclosure thermal management systems

Procurement Notes

Verify that the target enclosure complies with IEC standards to ensure compatibility with this top-mounted fan unit. Confirm that the power supply matches the specified 220 to 240 volt AC operating range. Ensure the physical dimensions allow for the required 4.69-inch body width clearance during installation.

Selection Notes

Select the DFN02 when top-mounting is preferred over side or bottom configurations. Choose this model specifically for applications requiring high airflow ventilation within IEC standard enclosures. Verify voltage requirements align with the 220-240V AC specification before procurement.

Part Context

This part belongs to the Hoffman ventilation fan series, which includes variants like the DFN01 for bottom mounting. The DFN02 is distinct in its orientation, directing airflow upward from the top surface. It functions as an accessory rather than a standalone enclosure, relying on integration with compatible housing units.

Replacement Considerations

The DFN01 is a confirmed substitute variant designed for bottom mounting. Select DFN01 only if the installation requires airflow direction from below rather than above. Both models share similar ventilation functions but differ in mounting orientation.
