20833353

Overview

The nVent SCHROFF part number 20833-353 is a RatiopacPRO Air self-adhesive sealing strip designed for 19-inch rack systems. It measures 84 HP in width and is intended to close the gap between the rear horizontal rail and the base plate. This component prevents air short circuits within the enclosure, ensuring efficient thermal management by directing airflow through installed equipment rather than bypassing it.

Feature Summary

• Self-adhesive design for rapid installation without additional fasteners
• Specifically engineered to seal the gap between rear horizontal rails and base plates
• Prevents internal air short circuits to maintain effective cooling performance

Applications

• 19-inch network cabinet installations
• Rack-mounted server chassis ventilation optimization
• Data center equipment cooling efficiency enhancement

Procurement Notes

Verify the exact part number format, as distributors may list it as 20833-353 or 2553896. Confirm compatibility with specific rack frame depths and rail configurations. Check for RoHS compliance documentation if required by project specifications. Ensure the 84 HP width matches the available space between rails.

Selection Notes

Select this seal when standard airflow paths are compromised by gaps at the rack base. It is suitable for environments requiring directed cooling without modifying the structural rack components. Consider the self-adhesive nature for maintenance accessibility and quick replacement during system upgrades.

Part Context

This component belongs to the RatiopacPRO series of rack accessories manufactured by nVent SCHROFF. The series focuses on standardized solutions for electronics packaging and rack organization. The product addresses common thermal issues in dense 19-inch rack deployments by managing internal air dynamics.

Replacement Considerations

No direct public substitute part numbers are confirmed for this specific 84 HP self-adhesive seal configuration.
