It features mild steel construction with dimensions of 2.5 inches by 48.5 inches (approximately 63.5 mm x 1232 mm). The unit provides free airflow capacities of up to 266 CFM (452 m³/hr) or 348 CFM (591 m³/hr), depending on operational conditions. It utilizes terminal block connections and is engineered to bolt securely to the enclosure top, ensuring a tight seal against environmental contaminants.

Feature Summary

• Designed specifically as a replacement filter media for HR16 top-mount filter fan systems
• Constructed from mild steel to provide durable filtration support within industrial enclosures
• Engineered to bolt directly to the enclosure top surface to maintain an airtight seal

Applications

• Replacement filter media for nVent HOFFMAN HR16 series top-mount filter fans
• Environmental control systems requiring high-volume air exchange in industrial enclosures
• Enclosure cooling applications where sealed filtration is critical for internal component protection

Procurement Notes

Verify compatibility with existing HR16 filter fan assemblies before installation. Confirm that the mounting interface matches the specific enclosure model utilizing this filter series. Ensure the replacement unit meets the required airflow specifications for the thermal management needs of the target application environment.

Selection Notes

Select this component only when replacing filters for HR16 series fans. Consider the specific airflow requirements of the enclosure; choose based on whether the 266 CFM or 348 CFM rating aligns with the thermal load. Verify physical dimensions fit the designated filter housing slot within the enclosure structure.

Part Context

This part belongs to the MCLF series of replacement filters manufactured by nVent HOFFMAN. It serves as a consumable maintenance item for active cooling systems rather than a standalone power unit. The component is integral to maintaining the IP rating of enclosures equipped with HR16 fans by filtering incoming air.
