As part of Trane’s 5TEM6 series platform, this air handler integrates a variable-speed ECM blower motor, all-aluminum plate-fin indoor coil, and insulated metal cabinet construction designed to support efficient heating and cooling operation across a wide range of installation environments.

Variable-Speed ECM Blower Motor Performance
The 5TEM6D04AV31SA utilizes a direct-drive centrifugal blower powered by a variable-speed ECM motor engineered for efficient airflow delivery and improved indoor comfort control. The blower operates at approximately 1050 RPM and provides nominal airflow of approximately 1,200 CFM , helping maintain consistent air distribution and system efficiency across residential HVAC applications.

3 Ton Air Handler Capacity Platform
Model nomenclature identifies this unit as part of the 3-ton air handler capacity platform , supporting nominal system capacities ranging from 24,000 to 42,000 BTU . The unit operates on 208/230V, 1-phase, 60 Hz electrical service , allowing compatibility with a wide range of matched outdoor heat pump and air conditioning systems designed for R-454B refrigerant operation.

All-Aluminum Plate-Fin Indoor Coil
The indoor coil features an all-aluminum plate-fin construction engineered for reliable heat transfer and corrosion resistance. The coil is designed for R-454B refrigerant systems and utilizes a thermal expansion valve (TXV) to precisely regulate refrigerant flow, supporting efficient system operation during both heating and cooling cycles.

Convertible Multi-Position Installation Design
The 5TEM6 series air handlers incorporate a 4-way convertible cabinet design , allowing installation in upflow, downflow, horizontal left, or horizontal right configurations . This flexibility enables installation in closets, basements, crawlspaces, attic spaces, or mechanical rooms depending on the building layout and HVAC system configuration.

Durable Insulated Metal Cabinet Construction
The cabinet features heavy-gauge metal construction with captured foil-faced insulation rated at R-4.2 , helping improve system efficiency while reducing cabinet condensation and operational noise. The cabinet is engineered to maintain 2% or less air leakage , supporting consistent airflow and overall system performance.

Draw-Through Airflow Design with Horizontal Drain Pan
The air handler uses a draw-through airflow configuration , promoting consistent air movement across the indoor coil for improved heat transfer performance. A factory-installed horizontal drain pan and 3/4-inch NPT condensate connection support reliable condensate drainage during cooling operation.

Electric Heat Compatibility for Supplemental Heating
The 5TEM6D04AV31S supports field-installed electric resistance heater kits from the Trane BAYHTR series, allowing optional supplemental heating capacity when paired with heat pump systems or used in electric heat applications. Multiple heater capacities are available to meet specific installation requirements.

Spacious Cabinet Design for Increased Airflow Capacity
The unit features cabinet dimensions of approximately 51.3 in. H × 23.5 in. W × 21.1 in. D , providing increased internal airflow capacity while remaining compact enough for typical residential mechanical spaces.

Engineered for Reliable Residential HVAC Performance
Ideal for medium-to-large residential HVAC systems, the Trane 5TEM6D04AV31S air handler delivers dependable airflow performance, durable coil construction, and flexible installation capability in a variable-speed indoor platform designed for efficient comfort and long-term reliability.
