39TF (ML)

Ceiling‑suspended packaged air handling unit with double‑wall construction and very low air leakage

The Carrier 39TF (ML) is a ceiling‑type, suspended packaged air handling unit designed to deliver reliable performance, high airtightness, and flexible air treatment in compact installations. Its robust aluminum frame, patented labyrinth sealing, and advanced filtration options make it suitable for demanding commercial HVAC applications.

39TF (ML)

Low air leakage rate: Formed by aluminum sections with concave and convex chamfer at the AHU body, the patented labyrinth seal structure provides low air leakage.

Robust:The AHU has an aluminum alloy frame and a hidden metal inner frame, in which the former constitutes a rigid body with high resistance to torsion by using a tenon structure and tightening with bolts and nuts, while the latter greatly improves the strength of the unit.

High performance filtration and UVGI options.
