Ultra-slim silhouette meets C-form coil engineering and steady-airflow assurance for projects where every millimeter of plenum depth counts.
Ceiling plenum depth is the critical constraint that impacts project timelines. When architects optimize for maximum floor-to-ceiling height, the ducted unit must be the slimmest component. The Midea V8 Arc Duct addresses this challenge with a uniform 199mm body height across all capacities and a minimal 450mm front-to-back depth—enabling installation between structural beams, in tight retrofit cavities, and above low-drop suspended ceilings where conventional units cannot fit.
The C-form heat exchanger represents advanced engineering: a continuous-bend coil geometry that eliminates seam joints where condensate pools and dust accumulates. This design ensures rapid and complete water evacuation while preventing particulate buildup. The result is a cleaner heat exchanger, extended maintenance intervals, and reduced operating costs for building owners. Combined with constant-airflow logic that automatically compensates for duct friction and filter loading, the Arc Duct maintains design performance from commissioning through its entire service life.
Core Highlights
01 — Uniform 199mm Envelope Across All Capacities
Every model in the Arc Duct lineup maintains the same 199mm vertical profile regardless of cooling capacity, enabling standardized ceiling depths across mixed-capacity zones.
02 — 450mm Depth for Beam-to-Beam Installation
The shallow 450mm chassis depth allows placement between standard structural beams and in narrow plenum corridors, expanding ducted VRF applications in space-constrained buildings.
03 — C-Form Coil: Seamless Drainage, Zero Particle Traps
Continuous-bend C-shaped coil eliminates seam joints and crevices that trap condensate and dust, reducing cleaning frequency and maintaining heat-transfer efficiency.
04 — Steady-Airflow Compensation Logic
Embedded airflow regulation algorithm continuously adjusts fan output to offset duct resistance changes and filter loading, ensuring consistent supply volume without field recalibration.
05 — Right-Angle Service Orientation
Orthogonal installation alignment with accessible service panels enables filter swaps, motor inspection, and drain-pan cleaning without removing the unit from its ceiling position.
06 — 1,200mm Drainage Head with Fault Signaling
Standard high-lift pump includes digital anomaly detection that issues pre-emptive fault signals before water escape occurs, providing maintenance windows for facility teams.
07 — Selectable Long-Life or Mid-Grade Filtration
Two filtration tiers allow matching filter type to environment requirements without chassis modification—long-life for low-maintenance scenarios, mid-grade for elevated particulate capture.
