1RB100M

Overview

The Hoffman Enclosures Inc. 1RB100M is a filter box fan designed for thermal management in industrial enclosures. It operates on 115 VAC with a power consumption of 90 Watts and draws 1.2 Amps. The unit provides an airflow rate of approximately 725 CFM (free flow CRM). Its physical dimensions are 13.38 inches by 13.38 inches by 4.50 inches. The construction features 18-gauge steel housing finished in light gray, complemented by an aluminum mesh filter element.

Feature Summary

• Provides active air filtration to maintain internal enclosure temperatures
• Constructed from durable 18-gauge steel for structural integrity
• Utilizes an aluminum mesh filter element for particulate removal

Applications

• Thermal management for electrical control panels
• Cooling for industrial automation enclosures
• Ventilation for telecommunications equipment housings

Procurement Notes

Verify the specific voltage requirement (115VAC) against site infrastructure before procurement. Confirm that the 13.38 x 13.38 inch mounting footprint aligns with existing cutout specifications. Ensure the 1.2 Amp current draw is supported by the local circuit protection devices. Check for compatibility with the intended enclosure material and finish requirements.

Selection Notes

Select this model when passive cooling is insufficient for the heat load. Compare airflow ratings against other units if higher volume is needed. Consider the aluminum filter maintenance cycle relative to the installation environment's dust levels. Verify that the 115VAC input matches available power sources in the target application area.

Part Context

This component belongs to the nVent Hoffman 1RB series of filter box fans. These units are engineered specifically for integration into metal enclosures to prevent overheating. The series typically offers various airflow capacities and voltage options to suit different enclosure sizes and regional power standards.

Replacement Considerations

Direct substitutes may include other models within the nVent Hoffman 1RB series with matching dimensions. Cross-reference airflow rates and voltage inputs when considering alternative brands. Ensure replacement units meet the same 18-gauge steel construction standards for durability.
