The SPACEPAK 45AC-PAJSQ is a fiberboard plenum adapter designed for use with electric heater systems. This adapter provides a transition interface between the plenum and the air distribution system, allowing proper airflow routing within the unit. Constructed from fiberboard, it is a lightweight, thermally suitable material commonly used in low-velocity air handling applications. HVAC technicians and installers working on SPACEPAK electric heater configurations will find this a straightforward OEM-style replacement component when the original adapter is damaged or missing.
This plenum adapter is intended for installation in electric heater applications within SPACEPAK systems. It is suited for residential and light commercial environments where SPACEPAK small-duct, high-velocity, or similar air handling configurations are in use. The adapter fits within the plenum assembly to maintain the integrity of the air pathway and is typically installed during system setup or service when plenum components require replacement.
Designed as an OEM-style replacement plenum adapter for SPACEPAK electric heater systems.
Installation should be performed by a licensed HVAC technician. Always disconnect and lock out electrical power to the system before accessing internal plenum components.
