Medium Static Duct FCU Concealed Quiet and Easy to Service Reversible Piping Duct FCU Fewer Surprises Behind the Ceiling

Concealed ducted fan coil units serve the spaces occupants judge most harshly — guestrooms, offices, clinics — precisely because nobody sees them until something goes wrong: a drip on the ceiling, a rattle at night, a stuffy room at the end of a long duct run. The Midea Medium Static Pressure Duct Fan Coil Unit is engineered to design those failures out. On AC models, water connections reverse from left to right on site; on DC models, external static pressure is selectable at 12, 30 or 50Pa via the PCB or wired controller. Return air draws from the rear or the bottom. Units adapt to as-built reality instead of forcing compromises that surface later as faults. One family spans 400–1200 CFM with cooling capacities from 2.35 to 13.78 kW across the AC and DC range.

At 241mm body height (261mm for DC), the chassis hides above standard ceiling grids, while three-row and four-row coil options match two-pipe or four-pipe hydraulics across the building. The enlarged drain pan option is low-cost insurance against the leak every facility manager dreads: condensation staining a finished ceiling and flooding the helpdesk with work orders. And because the filter assembly extracts in multiple directions, maintenance access works however the ceiling void ended up being built — your team services every unit quickly instead of inventing an access solution on every visit.

The DC inverter brushless range provides seven fan speeds for precise airflow balancing — rooms neither stuffy nor draughty, which means fewer comfort calls — plus up to 30% lower fan energy and native V8 controller integration for estates pairing FCUs with Midea VRF outdoor systems. XYE and PQE ports put central control and Modbus RTU within easy reach, so unit status lands on your central monitoring screen rather than on a clipboard round. Standard supply is 220–240V / 1Ph / 50Hz; for properties on other grids, Hongtai provides OEM/ODM support with custom voltages from 180–440V at 50/60Hz, project branding and protocol options.

• Site-Reversible Water Connections (AC) — Units adapt to as-built riser positions, so installation compromises never become your maintenance problem.
• Selectable ESP 12/30/50Pa (DC) — Airflow matched to the real ductwork at commissioning; no chronically under-ventilated rooms.
• Rear or Bottom Return Air — Return path suits the actual void; no custom plenums to inspect and repair later.
• Enlarged Drain Pan Option — Low-cost insurance against the ceiling-stain leaks that flood the helpdesk.
• Seven-Speed DC Balancing — Rooms tuned precisely between stuffy and draughty; fewer comfort complaints.
• Multi-Direction Filter Extraction — Filter access however the void was built; service visits stay short and predictable.
• V8 Integration, XYE / PQE Ports — Native VRF pairing plus central control and Modbus RTU visibility on one screen.
• Up To 30% Lower Fan Energy (DC) — Direct electricity savings across the concealed fleet.
• OEM/ODM via Hongtai — Custom voltage (180–440V, 50/60Hz), branding, protocols and long-term spares support.

The AC range is the robust default for standard duct runs where 3-speed control is adequate — and its on-site left/right piping reversal quietly prevents future maintenance headaches. Where noise ratings are written into the SLA, or energy performance is audited, choose the DC inverter brushless range: external static selectable at 12/30/50Pa via PCB or wired controller, seven-speed balancing, up to 30% fan energy saving and native V8 integration. Coil options, connections and service access are shared across both, so maintenance procedures and spares stay identical.
