The Unico System UPC-61-4860 Supply Air Plenum Adapter

Product Description

The THE UNICO SYSTEM UPC-61-4860 is a round, rigid supply air plenum adapter designed for use with high-velocity air handler systems in residential and light commercial applications. Constructed from galvanized steel, this adapter measures 10 inches in diameter and connects the air handler's supply outlet to the distribution plenum. At 4.0 pounds and built to AHRI-applicable standards, it provides a durable, corrosion-resistant interface point for system airflow. Licensed HVAC technicians install this component during new system commissioning or when replacing damaged plenum transition hardware on 4-5 ton equipment.

This adapter is intended for 4-5 ton high-velocity air handler installations where a 10-inch round supply connection is required. The rigid galvanized steel construction maintains duct geometry under the elevated static pressures characteristic of high-velocity systems. It is a key transition component between the air handler cabinet and the main supply trunk, making accurate sizing and secure attachment essential for system performance and efficiency.

Key Features

• 10-inch diameter round opening sized for 4-5 ton high-velocity air handler supply connections
• Galvanized steel construction resists corrosion in unconditioned mechanical spaces
• Rigid form maintains shape under high-velocity system static pressures
• Meets AHRI applicable standards for air distribution components
• Compact profile at 18 inches stated length for straightforward integration into tight mechanical spaces

Compatibility

Designed as an OEM-style replacement or new-installation supply air plenum adapter for 4-5 ton THE UNICO SYSTEM high-velocity air handlers requiring a 10-inch round supply air connection.

Installation Notes

Installation should be performed by a licensed HVAC technician familiar with high-velocity air distribution systems. Disconnect and lock out power to the air handler before beginning any plenum or duct work. Secure all connections with appropriate sheet metal fasteners and seal seams with listed duct sealant or mastic to maintain system static pressure integrity. Refer to local mechanical codes and AHRI guidelines for applicable installation requirements.
