Midea medium static pressure duct FCU site reversible piping selectable 400 1200 CFM V8 and Modbus ready OEM ODM via Hongtai

Concealed ducted work is where drawings meet reality — and reality usually wins. The Midea Medium Static Pressure Duct Fan Coil Unit is engineered to absorb the gaps between design and as-built conditions instead of making you pay for them. On AC models, water connections reverse from left to right on site; on DC models, external static pressure is selectable at 12, 30 or 50 Pa via the PCB or wired controller. Return air draws from the rear or the bottom. When the riser ends up on the wrong side or the duct run grows two extra bends, the unit adapts — no re-ordering, no return trips, no change-order arguments. One family spans 400–1200 CFM with cooling capacities from 2.35 to 13.78 kW across the AC and DC range.

At 241 mm body height (261 mm 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 new-build and retrofit jobs. The enlarged drain pan option is low-cost insurance against the call-back every contractor dreads: condensation stains on a finished ceiling. The filter assembly extracts in multiple directions, so maintenance access works however the ceiling void ended up being built — your service team will not be inventing access solutions on every visit.

The DC inverter brushless range provides seven fan speeds for precise airflow balancing at commissioning, up to 30% lower fan energy, and native V8 controller integration for jobs pairing FCUs with Midea VRF outdoor systems. XYE and PQE ports simplify central control and Modbus RTU handover to the BMS contractor. Standard supply is 220–240 V / 1Ph / 50 Hz; for export contracts, Hongtai provides OEM/ODM support with custom voltages from 180–440 V at 50/60 Hz, project branding and protocol options.

• Site-Reversible Water Connections (AC) — Swap left/right orientation on site in minutes; drawing changes do not mean re-ordering or return trips.
• Selectable ESP 12/30/50 Pa (DC) — Set static pressure at commissioning to match as-built ductwork; no factory pre-configuration lead time.
• Rear or Bottom Return Air — Adapts to actual void conditions without custom plenum fabrication.
• Enlarged Drain Pan Option — Low-cost insurance against condensation leaks and ceiling-stain call-backs.
• Seven-Speed DC Motor — Precise airflow balancing per room at commissioning; fewer comfort complaints after handover.
• Multi-Direction Filter Extraction — Service access works however the void was built; faster maintenance visits.
• V8 Controller Integration — Native pairing with Midea VRF systems for combined FCU and VRF tenders.
• XYE / PQE Ports — Straightforward central control and Modbus RTU handover to the BMS contractor.
• OEM/ODM via Hongtai — Custom voltage (180–440 V, 50/60 Hz), branding and protocols for export and tender projects.

The AC range is the rugged default for straightforward duct runs where 3-speed control is enough — and its on-site left/right piping reversal is a genuine site-proofing feature. Choose the DC inverter brushless range when duct layouts are complex or energy performance is specified: external static selectable at 12/30/50 Pa via PCB or wired controller, seven speeds for precise balancing, up to 30% fan energy saving, and native V8 integration for combined FCU and VRF tenders. Coil options, connections and service access are shared across both.
