1RB80M

Overview

The Hoffman 1RB80M is a filter box fan designed for thermal management in electrical enclosures. It operates on 230 VAC with an 80 W power rating and draws 1.1 to 1.5 A. The unit delivers an air flow rate of 390 CFM. Constructed from steel with a light gray finish, its physical dimensions are 10.13 x 10.13 x 4.50 inches. It utilizes an aluminum mesh filter type to maintain internal environmental conditions.

Feature Summary

• High volume air movement capability for effective heat dissipation
• Integrated aluminum mesh filtration system
• Steel construction with protective coating

Applications

• Thermal management of electrical control panels
• Cooling of industrial automation enclosures
• Environmental protection for sensitive electronic components

Procurement Notes

Verify the specific voltage requirement (230 VAC) against your facility's power supply before procurement. Confirm that the enclosure mounting hole dimensions match the 10.13 x 10.13 inch footprint. Ensure the required airflow of 390 CFM meets the thermal load calculations for the intended application. Check for any specific regional compliance certifications if applicable.

Selection Notes

Select this model when high airflow is needed within a standard panel size constraint. The 230 VAC operation distinguishes it from 115 VAC variants. Consider the steel construction for durability in industrial environments. Verify that the aluminum filter provides adequate particulate protection for the specific installation site.

Part Context

This component belongs to the nVent HOFFMAN MCLO series of filter box fans. These units are engineered as ready-to-populate solutions for panel builders. They integrate cooling and filtration into a single compact assembly, simplifying the design process for electrical enclosures requiring active thermal regulation.

Replacement Considerations

Cross-reference with other 230 VAC, 390 CFM filter fans from the same manufacturer family. Ensure dimensional compatibility with existing cutouts. Verify that substitute models offer equivalent airflow performance and filter efficiency ratings.
