Ductless Split-Type Multi-Poise Air Handler Indoor Unit R410A 4 Ton 48,000 BTU 208/230V 1 Phase 60 Hz High-Static 40MBAAQ48XA3

The Ductless Split-Type Multi-Poise Air Handler Indoor Unit R410A 4 Ton 48,000 BTU 208/230V 1 Phase 60 Hz High-Static (40MBAAQ48XA3) is the largest Bryant 40MBAA-series ducted air handler, built for high-capacity ductless applications requiring robust airflow and wide duct distribution. This 4 ton unit supports multi-poise installation, including upflow, downflow, horizontal left, and horizontal right positions, and maintains up to 0.8 in WC external static pressure so it can serve multi-branch supply systems or longer trunk lines. A high-efficiency DC fan motor provides multiple airflow selections appropriate for the 48K BTU range, enabling technicians to balance the duct system for comfort and noise control. Refrigerant connections are 3/8 inch liquid and 3/4 inch suction, with a 3/4 inch drain outlet for condensate management. The unit receives its power from the outdoor system at 208/230V single phase, 60 Hz. Cabinet dimensions of roughly 51.18 inches wide, 24.61 inches high, and 22.44 inches deep allow it to fit where larger fan coils or furnaces would normally be installed. For job fit, technicians should confirm outdoor-unit capacity pairing, ensure correct line-set sizing, verify duct static calculations, and maintain proper service clearances for routine access to the blower, coil, and filtration section.
