The Unico System UPC-61-2430 Supply Air Plenum Adapter

Product Description

The THE UNICO SYSTEM UPC-61-2430 is a round, rigid supply air plenum adapter designed for high-velocity air handler installations. Built from galvanized steel, this adapter connects the supply air plenum to the distribution system with a 7-inch diameter round outlet. It measures 16.75 inches in length, 11 inches in width, and 9 inches in height, and weighs 3 pounds. HVAC technicians use this component when configuring or replacing the supply-side plenum connection on Unico high-velocity systems sized for 2 to 2.5 ton applications. The rigid galvanized steel construction provides durability and resistance to deformation under system static pressure.

This plenum adapter is intended for use with high-velocity, small-duct HVAC air handler units in the 2 to 2.5 ton capacity range. It is suited for residential and light commercial installations where space constraints require the compact, high-velocity duct approach that Unico systems are designed around. The adapter fits into the supply air plenum section of the air handler cabinet and serves as the transition point to the round supply duct runs. Installers typically use this part during new system setup or when replacing a damaged or improperly sized plenum connection on an existing unit.

Key Features

• 7-inch diameter round outlet for compatibility with high-velocity supply duct connections
• Galvanized steel construction resists corrosion and maintains shape under sustained airflow pressure
• Rigid design provides a stable, leak-resistant plenum connection point
• Sized for 2 to 2.5 ton air handler applications
• Meets AHRI applicable standards for air distribution equipment

Compatibility

Designed as an OEM-style supply air plenum adapter for THE UNICO SYSTEM high-velocity air handlers in the 2 to 2.5 ton capacity range.

Installation Notes

Installation should be performed by a licensed HVAC technician. Power to the air handler must be disconnected at the breaker before beginning any work on the plenum or cabinet. Ensure all duct connections are properly sealed to prevent air leakage, which can reduce system efficiency and cause pressure imbalances in high-velocity systems. Follow local mechanical codes and manufacturer installation guidelines when securing the adapter to the air handler cabinet.
