The Hoffman Enclosures Inc. part number 89131499SP is a replacement grille designed for the HF04 series of equipment cooling fans. This component serves as a protective and aesthetic accessory for industrial enclosure thermal management systems. The unit is finished in black to match standard enclosure aesthetics. It is classified under Equipment Cooling Fan Accessories within the nVent Hoffman product portfolio, intended to maintain airflow while protecting internal fan mechanisms from debris.
Verify compatibility with existing HF04 fan models before installation. Confirm that the black finish meets specific environmental or aesthetic requirements for the target enclosure. Ensure the replacement grille matches the original mounting interface specifications to guarantee secure attachment and proper airflow alignment without modification.
Select this part specifically when replacing components for HF04 series fans. Do not substitute with generic grilles unless dimensions and mounting patterns are identical. Consider the black finish requirement if visual consistency with the enclosure is necessary. Verify that the application environment does not require specialized corrosion-resistant materials beyond standard construction.
This item belongs to the nVent Hoffman line of enclosure accessories, specifically categorized under equipment cooling and thermal management. It complements the broader range of NEMA-rated enclosures by providing essential fan protection. The product supports maintenance operations by offering a dedicated replacement part for aging or damaged cooling system components.
Confirmed substitute identifiers include the base number 89131499. Ensure the new unit matches the HF04 form factor. No alternative cross-references are publicly documented for this specific grille configuration.
