EFE250R5

Overview

The nVent Hoffman EFE250R5 is an EMC vertical filter fan designed for industrial enclosure ventilation. It provides a airflow rate of 125 m³/h while maintaining IP54 protection against dust and water jets. The unit operates on AC voltage at both 50 Hz and 60 Hz frequencies, rated at 230V. Constructed as a slide-in ventilator, it features a click-in installation mechanism for ease of mounting. This component integrates filtration to prevent particulate ingress, ensuring clean air circulation for sensitive electronic equipment housed within enclosures.

Feature Summary

• Vertical EMC filter design for enhanced electromagnetic compatibility
• IP54 rated protection against dust and water ingress
• Slide-in construction with click-in mounting feature
• Integrated filtration system for clean air circulation

Applications

• Automotive advanced driver assistance systems (ADAS) enclosures
• Enterprise machine control panels
• Personal computer industrial housing
• General industrial environmental control units

Procurement Notes

Verify the specific voltage frequency requirements (50 Hz or 60 Hz) match your facility's power supply before procurement. Confirm that the enclosure mounting dimensions accommodate the slide-in ventilator profile. Ensure the application environment does not exceed the operational limits defined in the official datasheet. Cross-reference the part number with the manufacturer's current product list to confirm availability and any potential supersessions.

Selection Notes

Select this model when high airflow combined with strict environmental sealing is required. The IP54 rating makes it suitable for dusty or wet industrial environments where standard fans would fail. The vertical orientation and slide-in design are ideal for space-constrained enclosures requiring quick maintenance access. Consider the EMC filtering capability if the enclosed electronics are sensitive to external interference or generate noise.

Part Context

This filter fan belongs to the nVent Hoffman environmental control product line, specifically engineered for industrial enclosures. It complements other Hoffman solutions like metal enclosures and panel fabrication tools. The EFE series focuses on providing reliable thermal management while protecting internal components from environmental contaminants, serving as a critical subsystem for durable electrical infrastructure.

Replacement Considerations

No public confirmed substitute part numbers are available in the provided documentation. Users should consult the manufacturer directly for cross-reference information or equivalent models with similar airflow and protection ratings.
