89136409R

Overview

The Hoffman Enclosures Inc. model 89136409R is a replacement filter kit designed for the HF series of enclosure cooling fans, specifically the HF09 models. This accessory provides IP55 rated protection against dust and water jets when installed in Type 12/NEMA 12 environments. The package contains six thermally bonded polyolefin filters with dimensions of 6.69 x 6.69 x 0.79 inches. These filters are engineered to maintain thermal efficiency while ensuring environmental sealing for industrial control enclosures.

Feature Summary

• Provides IP55 environmental protection against dust infiltration and water jets
• Compatible with all HF09 filter fan models for seamless integration
• Constructed from thermally bonded polyolefin material for durability

Applications

• Replacement maintenance for nVent Hoffman HF09 filter fans
• Industrial control panels requiring NEMA 12/IP55 ratings
• Enclosure cooling systems needing periodic filter renewal

Procurement Notes

Verify compatibility with existing HF09 filter fans before purchase. Confirm that the required protection level is IP55 rather than IP54, as filter specifications differ between these ratings. Ensure the installation environment matches the Type 12/NEMA 12 classification. Check for physical damage on incoming units upon receipt.

Selection Notes

Select this part only if maintaining or upgrading an existing HF09 fan assembly. It serves strictly as a consumable replacement component rather than a standalone cooling unit. Consider the frequency of maintenance cycles when determining order quantities, as the kit includes six individual filters for extended service intervals.

Part Context

This component belongs to the nVent Hoffman accessory line for enclosure climate control. It supports the broader HF series of passive cooling solutions. The product ensures continued operational reliability by replacing degraded filtration media. It is distinct from active cooling devices like air conditioners or heat exchangers.

Replacement Considerations

Official substitute part numbers are not explicitly confirmed in available public documentation. Verify exact dimensional fit (6.69x6.69x0.79 inches) if considering third-party alternatives. Ensure any replacement maintains the specified IP55 rating and polyolefin construction.
