89136408R

Overview

The nVent HOFFMAN 89136408R is a replacement filter assembly designed for the HF05 series of IP55 rated filter fans. This component serves as a consumable part to maintain the dust and moisture protection integrity of the enclosure cooling system. The package contains six units, each featuring thermally bonded polyolefin media. The physical dimensions of each filter element are 4.65 inches by 4.65 inches by 0.79 inches. These filters are specifically engineered to fit the HF05 model, ensuring proper airflow while preventing particulate ingress.

Feature Summary

• Constructed from thermally bonded polyolefin material for consistent filtration performance
• Designed to replace worn filters in HF05 IP55 filter fan assemblies
• Maintains specified ingress protection ratings against dust and water

Applications

• Replacement maintenance for nVent HOFFMAN HF05 IP55 filter fans
• Industrial electrical enclosure cooling systems requiring dust protection
• Control panel maintenance where IP55 environmental sealing is required

Procurement Notes

Verify that the existing cooling unit is an nVent HOFFMAN HF05 model before installation. Confirm the current filter rating matches the IP55 specification, as this part is not compatible with lower-rated or different series fans. Ensure the replacement quantity aligns with the six-unit packaging format provided by the manufacturer. Check for physical damage on incoming units prior to mounting.

Selection Notes

Select this part only when servicing HF05 series units. Do not use for HF01, HF02, or other non-HF05 models due to dimensional differences. Consider the IP55 requirement; if higher protection is needed, verify compatibility with alternative series. Evaluate the operational hours of existing filters to determine appropriate replacement intervals based on environmental dust levels.

Part Context

This component belongs to the nVent HOFFMAN MCLP series of enclosure accessories. It functions exclusively as a consumable media element for the HF05 filter fan product line. The part does not contain electronic components or moving parts, serving solely as a passive barrier within the thermal management system of industrial enclosures.

Replacement Considerations

Compatible alternate part numbers include 34725 and 13831658. Verify these identifiers match the specific manufacturing batch requirements before substitution.
