The Hoffman Enclosures Inc. part number 89106978SP is a rack filter accessory designed for industrial enclosure applications. The product specification indicates that the packaging quantity consists of four units per box, with each individual unit measuring eight inches by eight inches. This component serves as a supplementary element for maintaining environmental conditions within electrical enclosures.
Verify the specific application requirements against the eight-by-eight inch dimensions and the four-unit-per-box packaging configuration. Confirm compatibility with existing Hoffman rack systems before procurement. Ensure the intended use aligns with standard rack filter functions for enclosure maintenance.
Select this component when integrating ventilation solutions into compatible Hoffman rack structures. Consider the eight-by-eight inch footprint to ensure proper fit within the designated rack space. Evaluate the need for multiple units based on the four-unit packaging quantity to meet airflow requirements.
This item belongs to the Hoffman Enclosures accessories category, specifically supporting rack-mounted systems. It complements the broader range of enclosure management products offered by the manufacturer, focusing on auxiliary components rather than primary housing structures.
No publicly confirmed substitute part numbers are available in the provided documentation. Verify direct compatibility with existing rack frames before considering alternative sources.
