1RB80

Overview

The Hoffman 1RB80 is a filter box fan designed for electrical enclosure thermal management. It operates on 115 VAC with an 80 Watt power consumption and draws 1.1 Amps. The unit provides 390 CFM of airflow through the filter, while achieving 699 Free Flow CRM without filtration resistance. Constructed from steel with a light gray finish, its physical dimensions are 10.13 x 10.13 x 4.50 inches.

Feature Summary

• High volume air movement capability for efficient heat dissipation
• Minimal enclosure space requirement due to compact design
• Integrated filtration system for dust and debris protection

Applications

• Thermal management in industrial automation enclosures
• Cooling for electrical control panels
• Heat reduction in machine tool cabinets

Procurement Notes

Verify that the incoming unit matches the 1RB80 model number and confirms 115 VAC operation. Ensure the physical dimensions of 10.13 x 10.13 x 4.50 inches fit the target enclosure opening. Confirm the steel construction and light gray finish align with project specifications before installation.

Selection Notes

Select this model when high airflow is required within limited spatial constraints. The 115 VAC rating suits standard North American industrial power distributions. Consider the 390 CFM filtered performance as the primary metric for thermal load calculations rather than free flow ratings.

Part Context

This component belongs to the nVent HOFFMAN line of enclosure accessories. Filter box fans are engineered to replace traditional convection methods, offering active cooling solutions for sealed environments. The product series focuses on reliability and ease of integration into standard panel configurations.

Replacement Considerations

Cross-reference part number 22773 may be used as an alternative identifier. Verify mounting hole patterns and voltage compatibility when substituting with other Hoffman or third-party filter fans.
