Oxbox 5JMM4A0B36S31S Wall Mount Air Handler 3 Ton Psc Motor R-454B

Product Description

The Oxbox 5JMM4A0B36S31S is a 3-ton wall-mount air handler designed for residential split-system cooling and heat pump applications. It uses a PSC (permanent split capacitor) direct-drive motor and is rated for use with R-454B refrigerant, reflecting current low-GWP refrigerant requirements. The unit features an all-aluminum evaporator coil housed in a painted metal cabinet with foil-faced insulation, keeping the assembly compact enough for closet or attic installs. Licensed HVAC technicians install this unit as the indoor section of a split system, pairing it with a compatible outdoor condensing unit or heat pump.

This air handler is built for residential upflow wall-mount installations and is adaptable to 13, 14, and 16 SEER system configurations. The JMM4 series covers 1.5 to 3 ton capacities, and the 5JMM4A0B36S31S represents the 3-ton position in that lineup. It is suited for installations in small mechanical closets, open attics, and similar constrained spaces where a wall-mount configuration is required. Optional auxiliary electric heaters in 5 kW, 8 kW, and 10 kW ratings are available as accessories for applications requiring supplemental heat.
