Oxbox 5JMM5A0B30M21S Wall Mount Air Handler 2.5 Ton Ecm Motor R454B Front Return

Product Description

The Oxbox 5JMM5A0B30M21S is a 2.5-ton wall-mount air handler built for residential split-system heat pump applications. It uses an ECM (electronically commutated motor) for variable-speed airflow control, which improves efficiency and reduces energy consumption compared to standard PSC motors. The unit is designed for use with R454B refrigerant, aligning with current low-GWP refrigerant requirements. It features a front return configuration as the factory default, with a built-in filter rack included. ETL Listed and AHRI Certified, this air handler is a factory-matched component intended for licensed HVAC installation.

The 5JMM5A0B30M21S is designed for residential wall-mount installation, including closet and surface-wall configurations. It is matched for use with the J5HP5030A1000AA heat pump outdoor unit as part of a 14.3 SEER2-rated system. The unit supports bottom return conversion, allowing the installer to redirect return air from the factory front-return position to a bottom-return configuration depending on the installation layout. This flexibility makes it suitable for a range of residential spaces where floor or closet installations are common.
